To me, it wasn't. It's what Madalyn does, which is why I'm just waiting for her to reveal her cards. She knows the MC is too weak to resist temptation. Every time he shows some balls, confronts her about something, she does the same thing because she knows it WORKS. The idiot saw a ghost screaming in his FACE and she only had to suck him off to make him dismiss what he saw. That's how moronic this guy is, as if he never saw what he saw and barely thought about it again. If he caught Madalyn performing some satanic ritual, sacrificing goats or Ash himself on an altar, he's gonna forget all about it should she decide to fuck him after he catches her.
Yeah, that's our protagonist -_-
