Peter Parker In Gotham..
-but instead of Jason being Uncle Bens alternate self (or anything batfam being related to peter at all)- Peter finds out that actually theres a man who looks, sounds, acts, breathes, smells just like uncle Ben that works in some low down shithole of a bar as a bartender.
So Peter goes and does what any normal teenager in a new universe with no one who knows who he is, and stalks his alternate uncle.
At first he just thinks its some guy who is a version of his universes uncle. Then somehow he does smth that was so uniquely his uncle that peter goes on to like going through this guys files and paperwork and like hacking into the government to see if somehow this was his uncle and not another version.
Turns out that this man turned up in Gotham with no records whatsoever, no name in the system- nothing, four yrs ago. The year that he would have gotten shot.
The report of the case shows that Ben was injured, gunshot wound that could've killed him- nearly pierced his lung. He probably has a scar.
Peter ofc has a panic attack with this information because all the signs are currently pointing to the fact that this could be his uncle from his universe but had showed up here when he had died and got to live!!!
So he does the rational thing and enters the bar Ben works at, steps in right before closing time and watches as his uncle cleans the Bar.
He just stands and watches for a minute before Ben catches his eye and-
He recognizes him. He remembers him.
And all Peter hears is his uncle uttering his name before he bursts into tears like he was 6 yrs old again after a bad nightmare.
He ends up moving in with Ben who lives in an apartment above the bar. He helps get peter an identity with some connections he has made (he's like bffs with Gordon) and he enrolled peter in school and obvi they meet the batfam at some point but Peter gets his Uncle back and he gets to be Spider-Man and thats rlly all that matters to him..
