what if georgie comes back to life but is still the same age as when he died so bill has to be both his sibling and his parent. helping georgie walk through his problems and traumas and nightmares, which helps bill go through his own.

bill absolutely spoils georgie. georgie wants to play outside? bill drops whatever he's doing. georgie wants a stuffed animal at the fair? bill buys the whole booth. georgie definitely gets a smart phone. at first for emergencies but bill let's georgie buy all the games be wants

georgie doesn't have /too/ much trouble integrating to the 21st century nor did he have trouble making new friends, but sometimes the only people who he can relate to are adults.
all the Losers are very protective of him, even the ones who didn't know georgie in the 80s

georgie is definitely more reserved from /having his arm eaten off by a terrific clown monster/, but he still has his child optimism that makes bill very proud.

bill finds someone to fake documents saying georgie is his long lost relative whose parents have passed so he can be under bill's custody. georgie still calls bill his big brother but everyone on the outside makes their own assumptions why.

this idea started from seeing all those fic tags saying "everyone lives" everyone? including georgie? including baby georgie??

Also i know bill's whole thing is about dealing with loss but in this story he has already dealt with that and became at peace with it. but now that his little brother is back, all that progress isn't thrown away, but helps bill navigate a "new" life, aka parenthood
