What would happen if Anti_Auto didn’t crash and could stay at least a little stable?
He'd learn the truth about himself
Now scratching out the part where he'll probably go more insane from all that.
He'll try to go back home
*Anti_Auto happened after the Ask the Errors Series but before Autosearch was officially a thing
Oh yeah, Recall already has remembered being Geno the time Anti attempted to be Anti_Auto, so that's why he's wearing his scarf. And Hobo is kinda dangerous at this time point so he's not grabbing him home, nope.
Papyus wouldn't have turned to Tip_Top and TechD as well as Incy and Acsy(to an extent Eon) wouldn't exist are some of the changes of this hypothetical scenario. And if Anti so choose to stay, then A LOT of his kids wouldn't exist or at least...to him they dont.
But then again, would he really choose to leave his new life as anti and everything the future holds for him(newfound family, friends, creations and kids) for his old one?
Would he really think that changing his appearance hides the fact he's a different skeleton than he once was?
Would he consider staying long enough for a reset to happen in hopes that would change him back to being just sans?
Beats me
