kinda wanna post some doodles for it so here's some really vague context on another au
Absolute Catastrophe Timeline AU (or just Catastrophe AU)
-post-canon, second summer
-time traveling incident sends old grunks to swap places with their 8 year old selves
-8 year old grunks are like "woah it's the future" and ask a million questions. Dipper and Mabel don't have the heart to tell them that they don't get a boat until they're almost 60 so Mabel impulsively lies before Dipper can do the reasonable thing and say "oh I can't tell you too much about the future it could mess things up"
-kids explore around while Dipper and Mabel try to figure out what they should do. they try time traveling but are unable to find older grunks
-while exploring around, 8 year old grunks find the portal, decide it must OBVIOUSLY lead to their boat and switch it on (older Ford fixed it and was trying to make it stable. it still isn't very stable but it runs efficiently enough that it opens a lot quicker now)
-cue Dipper and Mabel being like "wait where did they go", feeling gravity get wonky like it does when the portal is on, and run to the basement
-they manage to save Stan but Dipper ends up going through the portal with Ford.
-Mabel is now stuck with no brother and an 8 year old Stan who just ALSO lost his brother. he also finds out from Mabel that the portal does not, in fact, lead to a boat.
-Dipper is stuck in the multiverse with an 8 year old Ford and has thus ended up having to take care of a child even though he is only 13 and therefore also a child. but he's also almost 14 so is it really THAT bad?? (it is. being 14 makes absolutely no difference)
-the twins do not reunite for a very long time
-the time police can't even help bc once you're in the multiverse, you're basically separated from your universe's timeline until you come back.
-since the time police can't help, they basically end up isolating that timeline. nobody is allowed to touch it anymore it's broken. they did take any and all time travel related devices tho so. yea
this is the shortest summary I could make lol
