Arya Takes More After Her Mother In Personality While Sansa Takes After Her Father's.

Arya takes more after her mother in personality while Sansa takes after her father's.

Sansa and Ned are more gentle and we don't really see them using physical force that much. Hell, they even try to save others from harm even if it was cause them harm in return. Ex) Ned giving Cersei a chance to run away with her kids because he knows that she and her children will possibly die if Robert finds out the truth but instead he is the one who is executed. Sansa telling Maragery the truth about Joffrey which becomes one of the reasons for Joffery's death but Sansa is framed for it.

Catelyn and Arya are not afraid to speak their minds and are pretty stubborn when they have their mind set on something. Catelyn who frees Jaime Lannister because even if having Jaime has a captive gives the North and its allies a advantage, she will do whatever it takes to get her daughters back. Arya refusing to give up her love for Needle despite her parents telling her that it's no such thing for a lady, even refusing to get rid of Needle when she joins the faceless men because it's the one few connections she has to her identity as Arya Stark, the girl with wolf blood.

Arya Month Day 2: Nymeria

Arya’s beloved direwolf Nymeria. Nymeria is named after a warrior queen whom Arya very much admired. Nymeria and Arya’s bond is immensely powerful. When Arya was in danger by the psychopathic Joffrey, instead of doing nothing but shouting and crying like Sansa, Nymeria leaped to Arya’s defense and gave that little shit what he deserved (hopefully it was painful). Sadly, knowing Nymeria would be killed for hurting Joffrey, Arya sends Nymeria away. Now Nymeria, having grown extremely large as she’s a direwolf, runs in the Riverlands with a massive pack of wolves. But Arya frequently thinks about her beloved wolf and has dreams of her. But they aren’t just dreams. Arya is a Warg like her siblings and can get inside Nymeria’s mind. Even from very long distances. A symbol of the immensely powerful bond they share. Hopefully one day Arya can reunite one day with her beloved direwolf and Nymeria’s pack could be a great asset to the living in the war against the Others.

And here’s one line highlighting how much Arya trusts her wolf.

“He grabbed the little girl by the hand and pulled her close. "What if the wolves come?""Yield," Arya suggested.”

Nymeria lives because at nine years old Arya was already capable of accepting difficult truths and making hard choices. 

She didn’t want to lose her wolf, she didn’t want to drive her away and she certainly didn’t want to throw stones at her. But when it is made clear to her that for Nymeria to stay would almost certainly mean her death, Arya accepted it and made the hard but brave decision to have Nymeria abandon her. She could have buried her head in the sand, clung to Nymeria and hoped that her father would stand between them and the Queen, but instead she picked up stones and threw them at her beloved pet, betraying her trust for her own good.

Now, Nymeria is alive, Nymeria is free, and Nymeria is a queen.

What has always been true is that the Arya/Lyanna parallels work both ways. It’s extremely meaningful to Lyanna to be paralleled with Arya in order to shed light on Lyanna’s inner world, in preparation for the reveal of a long held secret.

How it works is like this: because Arya defends Mycah against Joffrey, we can understand Lyanna’s defense of Howland. Because Arya never once strays from wanting justice for her brutally murdered friend, we can imagine what drove Lyanna to masquerade as the Knight of the Laughing Tree. And because Arya doesn’t think twice about any of this, we can understand Lyanna's convictions.

Because Arya loves exploring and discovering new plants she’s never seen before, because she brings flowers to Ned out of love, we can understand Lyanna being "fond of flowers" as part of a curious and affectionate nature.

Because Arya is never impressed with Joffrey, we can understand Lyanna's immediate assessment of Robert. Because her siblings react to news of Arya's betrothals to unsuitable partners with "Arya won't like that one bit" & "she never will, not Arya" & "[i]f he tries to lay a hand on her, she'll fight him," we can understand the gulf that opened between Lyanna and her family after her betrothal. Because amiable Elmar Frey looked down on Nan the serving girl and Arya resented him for it, we can see Lyanna judging Robert based on how he treats Mya/Mya's mother.

Because Bran thinks Arya "wasn't scared to get dirty, and she could run and fight and throw as good as a boy," because he first assumes Lyanna & Benjen fighting are him & Arya, we can imagine Lyanna & Benjen's relationship.

Because Arya is wolf-blooded and we see that written out, we can understand Lyanna as well.

That isn't to say it isn't meaningful to Arya, having Lyanna scattered through her story. Arya's complex relationship with mentor figures is a post to itself, but in brief: legacies are passed down by people, to people, who then use them as a starting/turning point. Daenerys Targaryen understands the duality of her family's legacy through the fragments of Viserys as her brother, king, and abuser; when he dies, she is the last, and she births dragons. Jon Snow is groomed for command in the Night's Watch just like his uncle and ancestors before him, charged with protecting his homeland in the shadow of an eight thousand year old Stark dynasty. Tyrion is Tywin writ small. The last greenseer waited generations just to haunt Brandon Stark's dreams.

Arya doesn't have that. She has a direwolf, she's a warg, and she has the North in her face. Wolf child, blood child; scattered yet meaningful pieces of a puzzle. By connecting her to Lyanna who came before her, it's a lineage. It's no longer an accident. Arya isn't Lyanna any more than Daenerys is Aegon the Conqueror, or Jon Snow is any of his predecessors, or Tyrion is Tywin, or Bran is Bloodraven, or Edric Dayne is Arthur, or Arianne is Nymeria. These parallels to (pre-series) characters represent a benchmark to be surpassed, whether or not the characters realize it themselves, and in Arya's case is no less.

Intentional parallels like this ask us: what if you were part of something - maybe even the culmination of something - that's been brewing for a very long while now? What if who & what you are is so important, so necessary, that time would fold in on itself for you?
