My favorite thing about my Jogan/Scemma fankids/timeline is that Sinister still finds new ways to keep terrorizing both families and adding newer layers of fucked up trauma.
Sinister finding out about the Jo/tt divorce: Falling to his knees outside a mcdonald's parking lot after finding out his otp pairing is no longer canon. So, he becomes even more toxic about it. He's lurking on the internet forums telling Emma and Logan to go kill themselves on a burner account for ruining everything. Then goes full eugenics and tries kill both them and the kids they had with Scott and Jean. Y'know how some spieces of animals - the males straight murder the females existing babies to force her into heat so he breed and establish his own progency. Yeah that.
