This is more of a Rex and Watevra-centered Au, mostly because I wanted to explore their dynamic after Rex was abandoned in Undar and proceeded to do everything in the second movie. And how Watevra took her 'dad's absence and presumed death, before meeting him again.
When she does meet him, he is nothing like how everyone described him (cause trauma), so this is also an Au that is letting Rex heal from his past mistreatment with the help of his kid that he tried to hurt in another timeline.
I guess the way this starts off is with Rex being back to the futuring to his timeline. There's gonna be that slight shock like why isn't he dead, but imma make sure he wakes up in the Rexcelsior with his Raptors, so he has that bit of comfort (How? I'll figure that out later) while he deals with the task of wrestling with his emotions from the failure of his revenge and the fact that Lucy actually came.
So, he decides to check out Syspocalypstar (After like maybe a month, he's not emotionally ready to do it immediately), 1. He doesn't really have anything better to do, and 2. He kinda wants to see what it's like considering he 'died' in the other timeline, and he was too caught up in revenge in his to see anything other than when Bianca was playing with his friends.
When he does get there, there's a lot of him just wandering around kind of being repulsed by the bright colors and sparkliness. Eventually, he does come across a statue of him, but it's when he was Emmet, and he gets a lot of mixed feelings seeing this statue. Because 1. It's showing him when he used to be naive and trusted everyone someone he's not anymore, 2. It means they cared enough to actually build it to remember him, and 3. They could've just built it as a might as well kind of thing instead of putting in any actual effort.
So Rex is just kind of frozen there in thought, and who comes along? His kid, Watevra pops in because she wants to visit her dad's memorial since it's the only real 'connection' she has with him outside of the stories and pictures his exfriends have of him.
She notices this dude who sticks out from the crowd a lot (But also there's not really anyone there) because he has the whole tough schtick that does still exist in the peace that came with the two systems coming together, just not at the intensity he's at.
Cue the 'Hey who are you?' Line from Watevra, because she would've remembered someone like Rex if he lived in Syspocalypstar. When they do make eye contact, there's this tension in Rex from having to deal with Watevra (his kid) on his first visit to Syspocalypstar.
Watevra almost instantly feels some kind of connection to this stranger that she just met, there is this bit of one-way conversation before she looks at the statue of her dad and compares it to Rex, seeing the resemblance before coming to the realization that OH, this is her dad.
There's gonna be mostly shock, definitely tears from Watevra as she hugs him, because her dad's not actually dead. Rex is mostly gonna be shocked because this is the first time he's really been hugged in years, but also that's his kid hugging him.
A sequence of Watevra spilling out a bunch of questions at him before they (Rex) decide to go someplace more private to talk since people are staring at their queen hugging a random stranger.
They have a talk with each other, Rex explaining where he was and what he did, and yeah Watevra is a bit surprised that this traumatized mess of a man is the person everyone told her about, but she still sympathizes and accepts him, explaining her side of the story. And Rex is still not ready to face his old friends, but he is willing to build a relationship with Watevra, and that's basically what the whole Au is gonna be about.
NOW this right here is like the first fic in the series that I'm planning to do.
What follows is a bunch of misunderstandings, Rex being hostile to his old friends and mayhem, and a wedding redo to make up for the rushed one five years ago, and this time Watevra's dad is actually here.
So yeah, I'm good to answer any questions anybody has about this Au, would love to be able to ramble about it some more. It's still in the early development stages, but I'm hoping to actually start writing it once I get my Undar fic out.
