#probably won't do anything with this AU. but i'm gonna name it the Age Shuffle AU just in case i do.

[hyperfixation-or-death]

Thinking about a Parallels AU where the main four + Camille are all different ages at the start of the show, and all the dynamics are different because of it.

The only main characters who have met at the start are Sam and Victor, and Sam and Bilal.

Sam is fifteen years old, so he's the closest to his canon age.

Victor is nine years old, so he's the youngest by a lot in this.

Bilal is thirty years old, and he's working with his mom on the tests. He also tutors Sam in math on the weekends.

Romane is nineteen years old, and hasn't met any of the other main characters.

Camille is nine years old, and she and Victor go to the same school.

Episode one starts when Sam is supposed to go to tutoring, but ends up needing to bring Victor with him, because their parents weren't able to pick him up from some activity or other.

I haven't figured out how they get to the woods from there; for the sake of convenience, let's say that cat Romane and Camille feed shows up injured, and they end up following the cat to try and help it? Work in progress.

Anyways, once they're close to the bunker, they run into Romane. Assuming we're going with the cat plot device, because I can't think of anything else right now, Romane was also trying to find the cat. The cat is gone now, though, and they're all about to turn back.

Then Victor notices the bunker (the key is in the door, idk), and wants to go inside. Sam and Bilal don't think it's a good idea, but Romane also wants to go inside for some reason, and the four end up going to check it out.

The test goes off, of course, and the timelines split.

Timeline 1 - Romane and Victor are left in the bunker.

Victor definitely blames himself for the disappearances, since he was the one to suggest going in the bunker in the first place. Romane also definitely blames herself for the disappearances, since Victor is nine years old, and she should have known it was a bad idea, but she didn't, and now this kid's brother is probably dead because of that.

Romane ends up talking to Victor afterwards, and realizes that he goes to school with Camille. The conversation turns to that, and Victor mentions that he's not doing great in some subject or other; a subject Romane happens to be good at. Feeling like it's the absolute least she could do for him, she offers to help him with homework after school.

Since Victor is literally an elementary school child, his parents are not sending him to boarding school. They do become increasingly distant and harsh, and Victor becomes increasingly convinced that they don't care about him.

Victor ends up spending a lot of time at Romane and Camille's house. At first, it's just because Romane's helping him with homework. Then it sinks in that no one else understands what happened in the bunker, and that fact starts playing into their dynamic. Then he starts to become friends with Camille. By the time four years have gone by, Victor and Camille are close friends, and Romane sees Victor as another sibling. (She hasn't moved out yet because a. She's attending university nearby. and b. She doesn't trust Herve and wants to keep an eye on her family.)

Then Vanessa Chassangre dies, and Romane is faced with the possibility of losing her sister. She's trying to figure out if she has any chance at getting custody, when Victor shows up to ask if she wants to go back to the bunker. Neither of them have figured out the correlation with the test in this AU, but they still go, out of sentimentality and curiosity and several other complicated emotions.

Test happens again; Victor and Romane time travel.

Timeline 2 - Romane and Bilal are left in the bunker.

Bilal connects the dots between the tests and the disappearances pretty quickly. He tells his mom. Then he tells Romane.

Bilal decides to try and find a way to save Sam and Victor. This time, it's less out of personal grief and more out of a sense of responsibility for what happened and guilt.

Romane graduates high school feeling completely lost. She doesn't know what she wants to do with her life, and she can't shake the guilt over what happened.

Haven't planned it out too well, but Bilal and Romane stay in contact. I'm not sure how it's going to work, but he's able to get her accepted for an internship at some point, and she ends up working with Bilal and Sofia.

The three of them continue to work at the time travel. Along the way, Romane becomes close with both Sofia and Bilal, viewing them as family.

Vanessa dies; Herve tries to take Camille. This time, it doesn't work. Romane has a support net, a steady income, and a future in the physics field. Romane gets custody of her sister.

They figure out the time travel. Bilal decides to go back.

Timeline 3 - Sam is left in the bunker; Bilal travels back to this one; Victor and Romane travel back to this one.

Since Bilal was already an adult before the time travel, Sam still recognizes him. He's clearly aged several years, though, which everyone is very confused about. Bilal has his canonical memory loss.

Idk what happens for the first day, but then Romane and Victor show up to the timeline at the same time they do in canon.

I haven't thought about how the plot changes from there, but the timeline where Victor kills Sam and then disappears after time traveling again doesn't happen. The official explanation is that they're able to stop it from happening the first time; the actual explanation is that I can't keep track of that many timelines in an already complicated AU.

Notes on the AU:

Camille ends up being there for the finale's events, both because she's a little older in the AU and because she's friends with Victor in the AU, so she insists on coming with the main characters.

Victor's emotional conflict ends up being roughly the same, because on the one hand, he's had more of a support net for those four years, but on the other, he's younger with more intense emotions, so it all kind of evens out.

For obvious reasons, none of the canon romantic relationships exist, with the exception of Sofia and Lieutenant Retz.

Obviously lots of things are different with this one, but I can't really think of a lot right now because I'm tired, so I might add to this later.
