Yay someone actually sent me an ask!!! Haha
Anyway, the point of this AU is kinda for the boys to get some independence from each other? I'm going off of my own experience with three siblings, so basically they're all sick and tired of having to share every little thing that they have, and they just wanna keep one thing to themselves.
And sure, that "one thing" happens to be pretty major, but hey, young kids have weird logic/perspective sometimes.
I do kinda wanna fit April into the au but I'm not sure how... might just give her a separate arc with her meeting and befriending Cassandra? I haven't really thought about this AU in a month because I've been busy with artfight
Also, in case it wasn't quite clear I guess I'll just tell you which characters they each befriend:
Leo befriends Hueso, Usagi, and Hueso Jr.
Donnie befriends the witch girl from the episode "Donnie vs Witch Town", and possibly also the bat librarian
Mikey makes friends with Mickey, before he became a criminal or joined the mud dogz, and drags him into doing petty vandalism (aka graffiti) with him
Raph joins a yokai knitting club, which includes the minotaur lady from the maze of death, and also Sunita's grandmother. Minotaur lady kinda becomes a mentor for Raph, and the googly lady introduces him to her granddaughter. So he's also friends with Sunita.
Oh yeah, I remember now, the point of this AU is to put the boys through a bunch of silly shenanigans as kids and see how close I can shove them without them realizing what the others are up to. It's just silly fluff that I'm gonna have fun with, so I say they're not gonna tell each other XD
