ok, theorising. Was the reverend really there? Like what if Manny is having a manic episode, which is kinda the reason he's now a serial killer, and hallucinating the reverend? if you look at the panels the reverend is only there when we get a close up of Manny and in those panels the reverend is right behind him, but then there's a panel from "didi's perspective" (the one at an angle) and there's no reverend.
If he's mildly aware that he's hallucinating the reverend, he might have thought he hallucinated the rape too. which is why he was so wishy washy with Sean.
tho I might be overthinking it ╮( ̄▽ ̄)╭









heck yes, this dream is hilarious
