I *called* it! When I saw Debbie I knew she was the Death Bringer, and when when I saw the "Death Bringer" I knew it was Mikey who would say Debbie is the Death Bringer once he was unmasked. Yay! I mean, nothing good ever happens to Anthony. What were the chances of Debbie showing up without any sort of twist?
What I didn't get was why Mikey didn't just say it at the start, which I assumed is just because he's been jerking Anthony around the whole time anyway, but somebody commenting here gave a much better explanation already.
It also occurs to me that now that Mikey's a demon, it doesn't matter how many times he's shot if there's no chicken around.
So if Anthony is still married and this series doesn't just ignore continuity from life and other series, maybe sister Ash and his dad will show up? And they'd probably side with the demons too. Ash probably already is a demon. She's behind the whole thing!
