I'm glad you liked chapter 9! Thanks for supporting the comic!
Gonna be perfectly honest, if somehow Battam's dad is revealed, it won't be in either the main comic or the big game. Might be in a secret third thing but that's for much much later.
Sorry if that's disappointing but the dude was a dick and genuinely just doesn't come back into his children's lives 😔 there's other really interesting parent drama in the big game though :]
