Wylan My Beloved - Tumblr Posts
We’ve been asking for a Wesper photo for so long. And now, we have a Polaroid photo and a video?! We are winning guys. Our prayers are being heard
I have finally seen my beloved Wesper together, I can finally die in peace. But not now because I need to watch season 2
The entire fandom went absolutely crazy over a 17 second video. What do you think’s gonna happen to us when season 2 comes out?
The Six of Crows fandom is being well fed
The piano scene in S2E3 is somehow talked about SO MUCH but also not enough, and I know that doesn't make sense but hear me out. Wylan has been in the Barrel for how long with nothing from his life before, only the decency he stubbornly clings to (hence why he initially refused to make bombs for Kaz, but his desperation got the better of him) and, if we use the information from the books, his flute. And we know the significance of music in Wylan's identity: he used it to hide his disability by setting whatever was read aloud to him to a melody in his head; the music room was the only place in his father's house he was ever happy in; and, in Crooked Kingdom, he recalls sitting at the piano bench with his mother, and it's one of the few memories he has of her because she "died" when he was young, so of course his memory of her is going to be a bit foggy.
Music wasn't something he got so good at to win his father's approval the way science and maths were - music was always his. It's what makes him Wylan and not Jan Van Eck's son, and being in the Barrel has tried to separate him from that part of his identity. Yes, he plays his flute in S2E1, but he plays it out of desperation. How long has it been since he's played music because of how connected he is to it, not because he needs money? It's something he yearns to do, and so when he and Jesper break into Pekka's country estate, Wylan doesn't take his eyes off the piano when he notices it - not even while Jesper is talking to him. He yearns to feel the press of the piano keys beneath his fingers, for the comfort playing music always gave him, and I think this is beautifully signified in that frame where presses the broken piano key: he so desperately wants that comfort and security, but can't have it.
Even though it looks like he sits at the piano to encourage Alby to keep playing, it's more so because he couldn't pass up the opportunity to do what he's yearned to do for so long. It's only 30ish seconds, but he loses himself in the music he plays, in that security he's sought since he first arrived in the Barrel. He's reliving sitting at the piano bench with his mother, and a show headcanon I have is that this little piece of music was something Marya taught him or wrote for him or something he wrote for her. Either way, it's made him lose himself in those happy childhood memories of him playing the piano with her.
Then that momentary peace and comfort is snatched away from him as he snaps back to reality. He's not at his father's house playing piano with his mother: he's in the Barrel, wrapped up in the company of literal criminals, and his mother's been dead since he was eight (well, we know she isn't dead, but he doesn't). His guard goes back up, and he goes back to being Wylan Hendriks, the demolitions expert keeping a privileged past and childhood traumas close to his chest, the boy who was desperate enough to start playing criminal with a band of thugs and thieves.

WHO GAVE THEM THE RIGHT TO POST THESE ON THE SAME DAY AS IF MY HEART CAN HANDLE IT


*jesper and wylan getting arrested*
officer, glaring at them both: anything you would like to confess?
jesper, glaring right back: nope
officer, nodding, writing on his pad: guilty
jesper, sputtering: but- what???
officer, ignoring him, turning to wylan: and you?
wylan, doing his best impression of a baby duckling: nope
officer, eyes narrowing:
wylan, blinking innocently:
officer, nodding again, writing on his notes: must have gotten lost
jesper, who knows that ALL successful parts of the plan were wylan’s and not his: oh come on-
Here's a friendly reminder that Wylan doesn't actually like chemistry, he's just good at it because he thought that being good at it would compensate for the fact that he can't read, that it would earn him his father's approval.
The next time I see someone call Wylan "boring" because his trauma isn't "as bad" as the other Crows' (namely Kaz and Inej's) I'm going to throttle someone. Firstly, trauma isn't comparable: trauma is trauma, regardless of what traumatic experience a person goes through. The point of Six of Crows is that all the Crows are traumatised but find comfort and solace within one another and galvanise each other's healing process.
Secondly, Wylan is a victim of ableism and emotional, mental and physical abuse - which is traumatic - and his story makes me feel physically ill whenever I think about it. As a disabled child, Wylan needed accommodations that his father refused to give him: instead, J*n treated him as something that needed fixing, and treated his disability as pure stubbornness that could be forced out of him with punishment and abuse. He "tried specialists, tonics, beatings, hypnotism" - which are traumatic. J*n also manipulated Wylan into believing that it was his fault by constantly shifting the blame to him (a behaviour very typical amongst abusers). As a result, Wylan never acknowledged his father's behaviour as abusive, which is why he tells Jesper in Crooked Kingdom that "he isn't evil" despite J*n literally trying to kill him twice. In fact, Wylan tries to justify how his father treated him, claiming that he "had done his best to care for his son, and if he’d failed, then the defect lay with Wylan." He also takes it as a display of affection and the desire to protect him, claiming that "his father might sound cruel, but he wasn’t just protecting himself or the Van Eck empire, he was protecting Wylan as well."
Wylan blaming himself for his father's actions doesn't stop there: in the period after Inej is kidnapped by J*n, Wylan feels responsible for what happened despite knowing that "he couldn’t have prevented his father from double-crossing the crew and kidnapping her. He knew that, but he still felt responsible". The guilt is eating away at him because he's so accustomed to taking the blame for his father's wrongdoings. Even after finding out the truth about his mother, which was really the catalyst for him recognising that J*n is indeed evil, his initial response is him blaming himself for it: "it was me. I caused this. He wanted a new wife. He wanted an heir. A real heir, not a moron who can barely spell his own name." This is only made even more sickening when we learn that Wylan would hear how his parents "fought all the time, sometimes about me", which would only amplify his feelings of responsibility for his father sending Marya away, stripping her of her life, family and fortune.
This is all without him not being allowed to grieve his mother's "death". This is all without the imposter syndrome and self-loathing Wylan experiences as a result of all of this, the fear that the Crows would see him as worthless and defective the way his father did and abandon him.
tl;dr: stop overlooking Wylan's trauma because he too has deep mental and emotional scars.
In the books, it's the scheming face. In the show, it's the bombastic side-eye.


Someone: what are you thinking about?
My brain: in Crooked Kingdom, Wylan tells Jesper that his father "places a high value on learning", to which Jesper replies with "higher than money?" that prompts Wylan to tell him that "knowledge isn't a sign of divine favour. Prosperity is." This obviously has religious undertones by referencing the belief that financial prosperity is a sign of the existence and aid of Ghezen, the god of industry and commerce worshipped by Kerch citizens, but it's also representative of certain facets of Wylan's character. J*n never valued his son's mind (the "knowledge" component of this analogy) because he thought that the "prosperity" of the Van Eck empire was impossible with a "defective" child, hence why he would refer to Wylan fulfilling the role as a mercher's son as an "impossible task" due to him not being able to read despite his other strengths in science, maths and music. He believed that Wylan not being able to read makes him "some fool who would make the Van Eck name a laughingstock", which would ultimately hinder the prosperity of the empire. This is why J*n "finally had to accept that Ghezen saw fit to curse me with a moron for a child": no matter how smart Wylan is and how much "knowledge" he has, his disability prevents the "prosperity" of the empire and, thus, there was no sign of divine favour. However, this ironic when you consider how Wylan becomes the reason for the empire's prosperity at Crooked Kingdom's conclusion. In this case, "knowledge" refers to his ability to read in the way his father perceived it: that it defined his intelligence and worth. His lack of knowledge (according to his father) may not have been a sign of divine favour - at least, not in the way J*n thought - but the prosperity of the empire under Wylan, his "defective" child, can be read as such. The fact that this line takes on a whole new meaning by the end of the duology is so representative of Wylan reclaiming his identity as he finally accepts all of himself - including the parts he'd learnt to hate and tried to outrun.
Me: ...beautiful weather we're having today, isn't it?
I will never move on from how not only did the Crows steal the tank from the Ice Court, but the entire time Wylan is smiling to himself and then absolutely LOSES IT once they've escaped. Like the crew has just stolen a tank from a high-security prison, narrowly escaping death, but Wylan physically can't stop laughing and is quite literally snorting with laughter at the image of the Fjerdans firing uselessly in the tank's direction with the Fjerdan might banner caught in its treads. He could have died but he's laughing hysterically at how stupid the Fjerdans look as they failed to prevent literal children (who have STOLEN ONE OF THEIR TANKS) from escaping their high-security prison. This has got to be one of my favourite underrated Wylan moments.
to the bone ━━━ a six of crows one-shot.

spoiler warning: this is not a safe space for fans who have only watched the show and do not want to have wylan's story spoiled for them in case we get the spin-off. this one-shot is based off a scene that is referenced in six of crows, and contains heavy spoilers for wylan's backstory which hasn't yet been explored in the showverse (I say "yet" because I'm holding onto hope that we'll get that spin-off asdfghjkl).
summary: ever since jan van eck had hired him for the mission at the ice court, kaz intended to use wylan as leverage against his father. but wylan had known from the start, from the moment that kaz had told him that he'd be excellent at hostage, that that wouldn't be effective. not when he'd been nothing but a disappointment to his father. not when van eck was hellbent on forgetting that he ever had a son. wylan couldn't keep it hidden anymore. kaz needed to know the truth. (or: the scene where wylan tells kaz about his disability.)
author's note: this work is a submission for grishaverse disability pride day by @gvdisabledpride that will also be available on ao3, so if you also see this work there... that's why :)

ABOARD THE FEROLIND after the battle at the Djerholm harbour, Wylan lay curled up in his cot below deck, waiting for the moment the sway of the ship would lull him to sleep.
Except he knew it probably wouldn't. He'd been lying in his cot for what felt like hours, tossing and turning, desperately trying to silence his racing thoughts and just fall asleep. He tried to focus on the sound of the sea muffled by the hull of the Ferolind, on the sway of the ship as it journeyed closer and closer to Ketterdam — but the freezing cold wasn't doing him any favours, and neither was that anxious gnawing in his gut.
The mission had been, considerably, a success: they'd escaped the Ice Court in one piece, with Kuwei Yul-Bo stashed away in one of the other cabins and the promise of thirty million kruge awaiting them back in Ketterdam. Wylan would get his share and leave this life behind. He'd journey somewhere far away, never having to speak the name Van Eck again.
Van Eck…
Wylan swallowed the bile rising up inside him. Kaz had intended to use him as leverage against his father, lest the plan go awry and Van Eck was suddenly uncooperative. “Wylan isn’t just good with the flint and fuss,” he'd announced that first day on the Ferolind, right before he'd revealed Wylan's true identity to the rest of the crew. “He's our insurance.”
Wylan shut his eyes, curled up tighter in his cot. His heart was starting to beat a little faster, a hummingbird trapped inside a cage, and he forced his breath slowly through his chest — a deep breath through his nose, shattering the silence that had thickened around him. Kaz had kept him close to use him as leverage against Van Eck, but one thing the older boy wasn't aware of was that Wylan couldn't be their insurance. Not when his father wanted him to disappear. Not when he was attempting to forget he ever had a son. Not when his new wife, Alys, was bearing the heir of the Van Eck empire — a proper hier, not the defective one he’d received in Wylan. Not the one who’d turn the Van Eck name into a laughingstock.
I have to tell Kaz.
Instinctively, his fingers reached up to touch his neck. He could still feel Prior's meaty hands clasped tightly around it, his grip firm and relentless as Wylan grew dizzy and black spots slowly filled his vision. He sat up, hoping the feeling would subside if he got up and let more air fill his lungs — and yet, the feeling of his throat constricting persisted, and a suffocating, uncontrollable panic welled up in him.
He hugged his knees to his chest and slowly rocked himself back and forth with his head buried in his arms, horrified by how his breath was coming out in short, shallow whimpers as the memories came flooding back, by how the tears prickled the corners of his eyes as his father's voice echoed in his ears.
A child half your age can effortlessly do what you cannot.
I've tried everything I possibly could. I've tried tutors, specialists, I've tried forcing that stubbornness out of you and yet you refuse to be taught.
You can't be sent anywhere because your defect might be revealed.
“Get out of my head,” Wylan whimpered, grabbing fistfuls of his hair as he continued to rock himself back and forth. “Get out of my head.”
Once you reveal yourself to be defective, they'll turn your back on you. They'll leave you as you were: the wayward son of one of the richest men in Ketterdam.
“Get… Get out of my head.”
But the voice was persistent, unwelcome. You worthless fool. You soft-pated idiot.
He pressed the heels of his hands to his eyes, blinking back the tears that formed a painful lump in his throat. He swallowed, trying to force it down to no avail, and a fresh flare of panic swelled within him. Someone could walk into his cabin at any moment and see him in this state: rocking back and forth with his head in his hands, chest shuddering over and over as he gasped for air, begging the voice in his head to lapse into silence. And yet, there was nothing he could do about it. He felt detached from his own body, as though he were watching himself from the perspective of an outsider, helpless against the wave of shame overcoming him.
He stayed like that until the jittery feeling coursing through him had subsided enough for him to think rationally again. Above that irrefutable voice in the back of his mind, he once again thought about revealing his greatest shame to Kaz. What would happen if he just stayed there on his cot, if he never told Kaz that he couldn't be used as leverage against his father? And what would happen if Van Eck double-crossed them, and there wasn't any good enough insurance to ensure that the six of them would get their money? Their efforts would have been futile, and none of them would get what they'd initially sought — and it might as well be his fault.
His body starting to tremble, Wylan forced himself to stand up from his cot. Just do one thing at a time. Just like his tutor had taught him in order to stop him from getting overwhelmed by the page. Stand up. He slid off the edge of the cot, straightened as his feet touched the ground. Take a deep breath. He closed his eyes, took another deep breath through his nose. Open your eyes. He opened his eyes and forced himself to walk. Go find Kaz. He assumed Kaz would be in his own cabin, scheming away, concocting backup plans for their backup plans in case anything went wrong.
He quietly left his cabin, making his way down the Ferolind's lower deck to find Kaz. He found the older boy sitting on the cot in his own cabin, staring intently at the floor with one hand gripping the crow head of his cane.
“Kaz?” Wylan swallowed frantically, his skin burning hot as he fought the words to come through. “I… I won't be leverage enough against my father. I know I'm supposed to be your… insurance, but I can't be. It won't be enough.”
Kaz sat up straighter, his free hand curling over the head of his cane as he looked up at Wylan. “And why is that?”
Something about Kaz's cold glare, his rock-salt rasp as he asked the question, sent a chill rippling over every inch of Wylan's skin. He wanted to scream. He wanted to bolt back to his cabin, hide beneath the paper-thin covers until he vanished completely. He wanted the floor to open up beneath him, to be dragged by the rolling waves into the depths of the sea. He wanted to disappear, just like his father wanted him to.
I have to tell him.
“I…” The roar of blood in his ears was deafening, drowning out the murmur of the waves outside the Ferolind's hull. That shameful helplessness was taut in his belly, a knot incapable of coming unravelled.
You just have to say it. You just have to say you can't read.
His father's taunts reverberated in his mind. Defective. Imbecile. Worthless. Broken. Disgraceful. Idiot. Useless. He was choking on them. They pressed against his throat like Prior's iron grip closing around it all those months ago, dirty fingernails digging into the skin of his neck. His cheeks burnt with shame despite the cold sweat that had broken out over every part of his body. His heart was a war drum beneath his ribs, his chest too tight, his breath too short and shallow. Take a deep breath. He couldn't. His clothes felt tight around his body — too tight, as though they stuck to him.
“I… I have an affliction.” Uttering those words aloud was enough to send a violent roil through Wylan's stomach, and he had to stop himself from throwing up. This was it. There was no taking back those words: he was halfway there.
Kaz merely sat there, looking rather impatient with his gloved hands folded over the crow's head of his cane. Wylan couldn't imagine what he looked like in this moment: red-faced, a trembling hand near his lips as if he were about to bite his nails, his eyes not meeting Kaz's.
It felt like the walls of the cabin were closing in on him, Prior's hands tightening around his throat as the latter half of his confession choked him. The waters he'd leapt into all those months ago were rising around him, filling his lungs and numbing his limbs with its icy grasp. He tried to fight against it, but the water was weighing him down, his limbs useless against the tide as he drowned in the murky waters of the Ketterdam harbour.
He drew another deep, shuddering breath.
Spit it out.
“I… I can't read,” he finally gasped, and the water receded.
There. He'd said it. He'd revealed his shame to Kaz, his voice barely above a whisper lest the sea around them carry his shame across its rolling waves and let the whole world know about Jan Van Eck's defective child.
Kaz's piercing glare was still on him, as if expecting him to say more. His expression remained as cold and calculating as ever — had he known about this too, just as he'd known about Wylan's true identity? Did Wylan have any tells that gave away his shame — his face growing pale at the sight of the tangled scrawl of words across a page, staring at it for too long hoping that he'd recognise the shapes of the words? Or had Kaz been surprised? Had this been the one thing he hadn't seen coming? His gaze was piercing and unreadable, but Wylan sucked in another breath and continued, trying to keep his voice steady.
“It's not that no one tried to teach me, lots of people did. But I just can't do it. It's like something in me refuses to do it.” That was what his father used to drill into him throughout his childhood, and the memory filled him with a sickening dread.
“I'm…” Wylan moistened his lips thoughtfully, trying to phrase his next words carefully without having the entire shameful story out in the open. The story of his father sending him away, supposedly to study music in Belendt. Of his Miggson and Prior trying to kill him, of him leaping into the murky canal with nothing but his satchel, fake enrolment papers and a soaked-through stash of kruge. “To him, I'm not worth losing. You can't use me as leverage if I'm not good enough insurance. There has to be another way around this, because this won't work. I know it won't.”
Kaz averted his gaze thoughtfully, then shrugged before standing up, leaning on his cane. That was his only response — a shrug. Had Wylan not been so afraid, so shaken by that shameful helplessness, he would have burst out laughing: he'd just revealed his defect to Kaz Brekker — the Bastard of the Barrel, the boy they called Dirtyhands in the grimy streets of the Barrel — and he'd merely shrugged. Shouldn't he be concerned with what to do with Wylan, now that he'd found out that his demolitions expert was just a useless fool evicted from his father's home?
“We'll have to work around that, then,” Kaz responded in that low, raspy voice. His eyes met Wylan's, boring into him as though searching for some semblance of worth within him, something that would compensate for his other failings. A pinprick of discomfort shot up Wylan's spine at the prolonged eye contact, but Kaz's eyes left his as he scanned Wylan from the top of his head down to the tips of his toes and back up again.
Wylan just stood there, completely stunned. He'd expected Kaz to sneer at him, or laugh at his affliction and refuse to give him his share of their reward once they'd reached Ketterdam. He'd expected the knot in his stomach to tighten, the shame growing, but he felt it loosen ever so slightly with the odd sense of relief and liberation that came with revealing his condition to Kaz.
“And how do you suppose we do that?” Wylan asked, his voice a low croak. “What other leverage could we possibly use?”
Kaz looked towards the door of his cabin, then back at Wylan. Kaz Brekker saw the world as though it were a puzzle, and he studied Wylan like he was a piece of that puzzle that didn't fit where he'd thought it would — but now, it seemed, he'd found another place he could slot that piece into without having to tear the entire project apart. “Lest Van Eck double-crosses us, we'll have to stop him from getting what he wants.”
Wylan's brow furrowed. “And how, exactly, would we do that?”
“Nina's a passable Tailor at best — but, under the influence of parem, she could achieve something that shouldn't be possible. Not even in the hands of the most gifted Tailor.” Wylan swallowed thickly as Kaz continued. “We'll have her tailor you to look like Kuwei, and hand you off to your father.”
Wylan's heart stuttered at that. He was no stranger to Kaz's elaborate and unbelievable schemes — after all, they'd stolen a tank from a high-security prison — but this was different. This was absurd. Wylan agreeing to be tailored to look like Kuwei was a death wish: the Shu boy was valuable, certainly with large bounties on his head. He held the secret to the world's greatest threat, one that could wreak havoc if it fell into the wrong hands. Wylan could have refused — he should have refused, if he wanted to make it back to Ketterdam alive. Instead, he cleared his throat and responded with an assertive, “I'll do it.”
For a split second, a surprised look flashed in Kaz's eyes, but disappeared as quickly as it came. He expected me to refuse, Wylan thought as his cheeks heated with embarrassment once again.
“It may be permanent,” Kaz warned him.
Wylan shook his head. “I need to know. Once and for all, I need to know what my father really thinks of me.”
Kaz cast him an almost pitying look. “Surely Van Eck would have some qualms about ending your life—”
“He wouldn't,” Wylan asserted, picking at the skin of his lip, that ill feeling returning as the reality dawned on him. Van Eck had tried to kill him once, what would stop him from trying again? “I'll bet you that.”
“How much?”
“Ten kruge.”
Kaz's lip curled in a grin. “Surely your father wouldn't be so callous.”
Wylan shrugged. “You'd be surprised.”
“Nothing surprises me, merchling. That's why I'm still alive.” Kaz walked past Wylan and made his way to the cabin's entrance. “I'm going to fill Nina in on the plan. Go to her cabin within the hour.”
Wylan nodded as Kaz left the cabin, leaving Wylan alone with nothing but his own racing thoughts. When he'd finally gotten himself to move, he walked back to his own cabin and propped himself down on his cot, his body still trembling with the aftermath of confessing his greatest shame to Kaz. His fingers itched the way they always did whenever he yearned to play his flute or the piano in the music room of his father's house. Ghezen and his works, he wanted nothing more than to snatch his satchel up from the foot of his cot and grab his flute. He wanted to close his eyes and bring the instrument to his lips, letting the world disappear around him as the notes wrapped him in his own story — one free of the shame and fear he'd carried for so long, one that made his heart flutter with joy as the music flooded a soothing warmth through him. But he couldn't bring himself to even glance in the direction of his satchel.
He thought back to Kaz's unchanged expression at his admission, the light, dismissive shrug of his shoulders. The shame still gnawed at Wylan, but there was also the strange relief of getting something off his chest despite it, as though telling Kaz had freed something in him — something that had been encased in the chains of his father's contempt for as long as he could remember.
It's not too late to decline, pressed that voice in the back of his mind.
He shook his head assertively — if this is what had to be done to ensure the crew got their money, then so be it. And yet… he was terrified and horribly anxious.
He looked down at his hands, his eyes tracing over the creases of his slender fingers, the little scars with no clear origin along his skin, the crescent outlines on his palms from digging his nails into them. Within the hour, they weren't going to be his hands anymore — they'd be Kuwei's. Slowly, he buried his face in his hands, sighing deeply as his fingers raked through the tufts of hair that brushed his forehead. The face in his hands wouldn't be his anymore, and neither would the hair between his fingers. With Nina's power, he'd soon become the most valuable person in the world. He was terrified, but that wouldn't stop him from doing what he needed to. From ensuring that he and the rest of this crew got their money.
From finally learning what his father truly thought of him.
Van Eck had made it clear as Wylan grew up that there was no space for his son in his household. He'd made it clear that he wanted Wylan disappear for as long as it took him to forget that he ever had a son. And yet, a part of him hoped that maybe he'd misunderstood everything. That his father did indeed love him unconditionally just as any father loved his child.
Wylan lifted his head from his hands and started gnawing at his thumbnail. He wouldn't know for certain until the rest of Kaz's plan was carried out, when his face and name were no longer his.
Currently reading Crooked Kingdom & this is what I find in ch 14:


Maaaaan, I love this show❤️
I know Wylan saying "always hit where the mark isn't looking" in Crooked Kingdom is supposed to be a humorous nod to his "who's Mark?" line in Six of Crows but I can't help but think of it as a representation of an overlooked facet of his character development.
What I find the fandom forgets is that he's ultimately the least experienced of the Crows and the one who, let's be honest, is the least cut out to be a criminal. It has nothing to do with him being soft or whimpy (I want to unleash my inner Dirtyhands every time I hear someone say that), it's simply because he spent most of his life sheltered from the brutality of the Barrel. Yes, his household was abusive, but "he’d never had to work for anything. He’d had servants, hot meals, clean clothes. Whatever it took to survive the Barrel, Wylan knew he didn’t have it" - and he spent a total of three months in the Barrel prior to the events of Six of Crows. Had he not started doing demo for the Dregs, he would have definitely died in the Barrel - especially considering how he clings to his decency and morality because it's all he's got left, but they won't get him very far in a place like the Barrel.
Due to his inexperience, as Leigh puts it in the Crooked Kingdom collector's edition, he "wasn't a Crow yet" in book one: he wasn't accustomed to Barrel life, let alone the life of a criminal. (It also references how he learns to trust his crew and is now a part of them not out of desperation, but out of a bond beyond blood, but that's for another time.) Going from not understanding what "[hitting] the mark" means because he's autistic to, as Jesper puts it, "[being] thoroughly corrupted" signifies how he's finally started becoming accustomed to a life he's never had to lead before.
Something I don't see anyone speak about (if you have and I just haven't seen it... I'm sorry :( ) is how Wylan not only reclaims his identity by the duology's conclusion, but he also reclaims Marya's. I feel like we as a fandom overlook just how much J*n put Marya through in an attempt to erase Wylan from the public memory: he had her declared insane as a grounds for divorce and institutionalised her, leaving her "abandoned along with her defective child" in order to "forever rid himself of any evidence that Wylan had existed". This transcended to J*n not allowing Wylan to grieve his mother's 'death' because, as he put it, "it didn’t pay to dwell on the past" - and Wylan tells Jesper that J*n never brought Marya up after breaking the news of her finality to his son, confessing "we just stopped talking about her".
What we also need to remember is that the Van Eck mansion "had belonged to Wylan’s mother’s family for generations before Van Eck had ever set foot through the door". (Edit: I didn't mean to write that the mansion belonged to the Hendriks - it was part of the property under the Van Eck name. Sorry about that!) Just like how J*n separated Wylan from his mother, he simultaneously took so much from Marya - first her home, then her name, her fortune, her own child. This is why Marya was admitted as Marya Hendriks, not Marya Van Eck: this is J*n quite literally stripping her of her name to permanently erase her from the public memory. The nurse addresses Marya as "Miss Hendriks", to which Marya mutters "Van Eck" in response, because "she was not Marya Hendriks, she was Marya Van Eck, a wife and mother stripped of her name and her fortune." So why is it that Wylan says, "I am Marya Hendriks' son" if Marya Hendriks is the woman who's left after Marya Van Eck had her name and her life taken away from her? Because this is Wylan reclaiming his mother's identity.
If we examine the moment Wylan visits his mother at Saint Hilde, Marya's first words to him are "did you come for my money? I don’t have any money" to which Wylan replies that he doesn't have any money either. The money neither of them have comes to signify the lack of autonomy they have over their identities, which have spent so long confined by J*n's contempt as he gradually works towards making them vanish entirely. J*n tried desperately to erase Marya's memory as a means of gradually erasing Wylan's - however, Wylan is the only one who keeps his mother's memory alive, just like how Marya keeps her son's alive. Upon arriving in the Barrel, Wylan detaches himself from his father's name and, instead, uses his mother's maiden name. Yes, he's doing it to not draw attention to himself (because what would the child of one of the richest men in Ketterdam be doing in a place like the Barrel?), but he's also preserving Marya's memory, clinging to it like a lifeline without even realising it. In a way, it's saving him.
Before I go on any further, I'm taking a brief detour to discuss the transition in Wylan's motivations upon discovering what really happened to his mother (it's relevant, I promise). Wylan completely breaking down when he realises that his father is indeed evil is such a pivotal moment that marks a major transition in his motivations. Jesper comforts Wylan during his breakdown, assuring him that "Kaz is going to tear your father’s damn life apart" - a sentiment that "felt like cool water cascading over the hot, shameful feeling of helplessness he’d [Wylan] been carrying with him for so long". His continued contribution to the Dregs’ mission is no longer about making the money to “get out of town and never speak the name Van Eck again” - now, he's "here for her". Now, it's about punishing his father, saving Marya and returning all J*n took from her: “what am I doing here? But he knew the answer. Only he could see his father punished for what he’d done. Only he could see his mother free.” He realises that J*n's life falling apart means that, with his money, "he could take his mother from this place. They could go somewhere warm. He could put her in front of a piano, get her to play, take her somewhere full of bright colors and beautiful sounds. They could go to Novyi Zem. They could go anywhere." He could save her, liberate her from the confines of J*n's contempt - and only he can do it, because who else would?
Meanwhile, Marya clings to the memories of her child even though J*n took him away from her. While institutionalised, Marya would paint - and in her paintings, "repeated again and again, was the face of a little boy with ruddy curls and bright blue eyes". We know that J*n wanted Wylan to disappear "the way he’d made Wylan’s mother disappear" - what we don't know, however, is what J*n told Marya during the time she was institutionalised. Did he visit her after sending Wylan away, supposedly to study music in Belendt, to tell her that Wylan is dead? Did he ever visit her before then and tell her that her son is dead to expunge his memory from Marya? We can only speculate - but what we do know is that, regardless of whether or not she thinks he's dead, Marya is grieving the loss of her child.
Something that Wylan fears if the Dregs’ mission is unsuccessful is that he’s “going to die and there will be no one to help her. No one to even remember Marya Hendriks” - and the same could be said about Marya’s feelings of responsibility for preserving the spirit of her child. Amidst her grief is the strive to save him and his memory, because she’s really the only one who’s willing to remember him. At the asylum, her paintings are thrown out “every six months” because “there just isn’t enough space for them” - but that doesn’t stop her from continuing to paint the face of her child and, thus, remembering him, making sure he doesn't disappear. Wylan confesses to Jesper that his parents “fought all the time, sometimes about me”, revealing how Marya has always fought for Wylan - and her being institutionalised, having her paintings thrown out every so often, won’t put an end to her fighting for him. She's hellbent on ensuring he doesn't vanish, because there’s no one else who would. (Think of this in relation to the meaning behind “no mourners, no funerals” - if Wylan disappeared, “no one would come looking”, as is the case with the rest of the Crows.)
Now, let's examine how, by the end of the duology, Wylan not only liberates himself from the pain caused by his father's wrongdoings, but also saves his mother. He'd "chosen to use a portion of his newfound wealth to restore his home", exemplifying how inheriting his father's fortune represents him reclaiming his identity from the pain and abuse J*n's contempt inflicted upon him. However, I mentioned earlier that the Van Eck mansion didn't actually belong to the Van Ecks in the first place - it belonged to the Hendriks. (Edit: again, not the mansion, but part of the property under the Van Eck name.) Thus, Wylan's position by the end of Crooked Kingdom also comes to represent him reclaiming his mother's identity as he returns everything J*n took from her. By "restor[ing] his home", he's also restoring Marya's.
Wylan's wide-eyed reaction to Kaz calling him his demolitions expert is even funnier when you realise that Wylan actually has no idea what he's doing, like he canonically agreed to do demo work for the Dregs without even knowing the first thing about demo and now he's suddenly being called an expert at it and he just has to go along with it because this is his job and therefore he needs to at least act like he knows what he's doing (even though he has absolutely no clue and he's only doing this because he's desperate).
We all talk about how Wylan was abused by his father, but what I don’t see a lot of people talking about is how J*n didn’t even allow his son to grieve his mother’s loss. At that age, Wylan probably would have only started to grasp the concept of death, and he also needed time to process and grieve Marya’s finality - and J*n wouldn’t let him do either. And to make matters worse, Wylan needed his father there for him during that time and instead J*n just gave up on him. He wouldn't even let Wylan talk about his mother and instead expected him to simply suppress his grief because "it didn’t pay to dwell on the past". This would have done just as much emotional and mental damage to Wylan as his father’s abuse and I don’t know why more people aren’t talking about it.
