When Jonas (dead camper) recounted the murders, and we saw Margaret standing, bloody, and starring out the window, I pretty much knew she was the killer. Her talk with the Night Stalker was also an indication. Didn't see the weird "love" story between her and Jingles though. Maybe Jonas saves the day, somehow.
I'm really hoping that Trevor isn't dead. I loved his character and want more of him. Poor Birdie, but I'm glad she helped Xavier out of the oven. It's no secret I love me some Cody Fern. Now he can't be on the cover of TV Guide!
Anyways, I'm loving and having fun with season, seeing I had a shit ton of questions/stories that didn't get answered in Apocalypse.
