Reminder, Angel died in the 40s. Val died in the 70s. Angel Dust was in Hell for three decades prior to Val. You'd think he'd learn some lessons throughout those three decades. You'd think that Angel would've been something else. You'd think Angel was already an established pornstar and Valentino just so happened to be his next manager.
But this is all speculation because we have yet to know anything about Angel Dust's experience in Hell—darn it, this goes for all the sinners. What were there personal experiences with Hell? Why did we get no dialogue or backstory on the things they've been through? That would've allowed us to sympathize with Angel Dust further. We would've seen what led to him being under Val's lock and key. But no, everything'll be up to interpretation because we all know Vivziepop will only yammer such information in her lousy tweets or in an interview/livestream. If we do get such answers, better wait until 2027 when season three comes out.
Once again, the more pieces you pick and hold on how buck broken this worldbuilding/character building is, the bigger you realize the puzzle is to where it'll only leave you more frustrated than ever.
