Sparkly Coin Au - Tumblr Posts
I LOVE THIS GIVE ME MORE
So a while ago some friends were talking about fans who claim the Same Coin theory is canon. And I made the mistake of saying:
Do you know who also has tons in common with Bill? Mabel. Yet nobody claims Bill reincarnated as Mabel. …wait now I want a "same coin but it's Mabel" AU. Funniest Bill reincarnation option. The all-seeing arsonist is making macaroni glitter art. The omnipotent tyrant is crying because a unicorn called her a bad person.
And then I overthought it for two months.
So—AU where after death, Bill's soul shoots 13 years into the past and reincarnates as Mabel. I'll call it ✨ Sparkly Coin AU ✨

Don't leave yet. Lemme show you why it works. Behold the eerie amount of parallels in their personalities, dialogue, behavior, mannerisms, tastes...



I could have kept going but my attention span ran out. All right, we all on board now? Convinced we could segue from one personality into the other? Great. Now here's why you should be interested: the juicy post-Weirdmageddon angst potential.

As long as a small fringe of the fandom still thinks Weirdmageddon is Mabel's fault, why not amp that up x100 and have some fun with it?
Is everyone sold now? Great. Let's get into the details. I've got 8 more pieces of art under the read more.
So the AU starts the instant Bill dies. Thanks to invoking his deal with the Axolotl—one way to absolve his crime, a different form, a different time—the Axolotl gives him a new shape and shoots him thirteen years into the past. Apparently, the Axolotl thought it would be very funny to stick Bill in the family that defeated him.
Which probably made for a jarring transition.

(It's fine, she's like 10 minutes old, she probably can't even tell who she's looking at. Not being able to tell who she was looking at is what got her into this situation ayyyy)
When Dipper & Mabel come back from Gravity Falls complaining about this triangular jerk Bill, their parents mention that Dipper's name was nearly Bill. See, after they knew they were going to have a boy, one night their mom dreamed about a visitor—some kind of magic pink salamander??—calling her child "BILL." Then at the next sonogram they found out they were having twins, the girl must've been hidden at a weird angle the first time, and they wanted matching names, so they thought, Bill and Bell. But they didn't really like Bell; but eventually they stumbled on Mabel, so to keep the names matching they switched from Bill to Mason. Isn't that the darnedest thing?
(Of course, Mabel and Dipper assume Bill harassed their parents to try to trick them into naming a kid after him. To be a jerk.)
When Bill meets Mabel, he's unaware that she's his future self—Bill's notably bad at doing things like, say, double-checking to see whether he's going to die anytime soon—but like... he can tell something's up.

Naturally, before visiting Gravity Falls, there were echoes of who Mabel used to be—but nothing anyone would be able to identify without context. All her Bill-ish quirks either smoothed out with time (see: how between second grade and fourth grade Mabel went from being the "freak" to the popular girl in class), or else they were accepted by her family as Mabel-ish quirks.


After they meet (and kill) Bill, they have the context to understand some of Mabel's behaviors... and unfortunately, some of Mabel's latent Bill-ness starts surfacing after she's been directly exposed to her prior incarnation.



The part of the Pines family familiar with Bill thinks the worst case scenario is that maybe Bill's survived and is slowly possessing Mabel; but far more likely, they think this is just some weird way of trying to subconsciously process last summer. Mabel doesn't think she's being weird, you guys are being weird, stop giving her weird looks. They get attacked by one triangle and now she can't wear yellow or pick up macrame as a hobby??
(It's not all red flags and uncomfortable triangle imagery, though. When Stan asks her what she'd like as a gift for some important event, she shyly admits that she thinks she's starting to outgrow her plastic gem jewelry and maybe she's old enough to get her first piece of real gold jewelry, if that's not too expensive? And Stan's never been so proud of her. Thirteen years old and already thinking about buying gold!)
But of course, the real fun starts when Mabel finds out.

That's the face of a girl who's just discovered that she tortured her great uncle. Now imagine running into the brother she possessed.
But I've already spent a million words and thirteen images on this post. If enough folks are interested in the AU maybe I'll expand on it later. Let me know what y'all think.
Goldie and Sparkly Coin!Mabel meeting would be very funny. Because this Mabel technically would be his big sister

posts that are inscrutable without knowledge of two separate fics/AUs
Mabel finally got that little brother she always wanted
