I was reading a fanfiction about Wally and Bart Fluff and like half way through I had this random thought of them actually finding a way to send Bart back to the future and thinking Bart will be excited to go back because "he didn't want to be stuck in the past" and "he must miss his family and friends" along with "this parents must be so worried".
But when they go to tell Bart he just kinda freezes for a second before dropping to the floor and hyperventilating, mumbling (or screaming either works) "I don't wanna go back, I don't wanna go back, I don't wanna go back" on repeat. Everyone is instantly really concerned and either Wally or Barry calm him down cause flash family fluff is required.
Bart tries to play it of as nothing but no one buys that and everyone is really concerned. Finally Barry and/or Wally manage to get out of him that the future is f*cked up and this leads to heartfelt hugs and words of reassurance and Bart finally gets f*ucking therapy because the boy needs it.
In summary Bart needs therapy, flash family fluff is best fluff and I desperately need someone to write this because I thrive off angst/comfort but have no motivation to write it myself.
