"Y'know, by the time the first body is found, it's only a matter of time before the bloodbath commences."
Noah Foster, Pilot
Good episode. though the "Noah, it will never work because you love Audrey" thing kinda came out of nowhere. I never got that from their relationship at all
I'm really starting to think Noah is the killer. The new killer is much smarter than the previous one. Way more cruel and manipulating, laying traps, psychological attacks, using drugs and misdirection, with a focus on Audrey and following rules that he himself set out in the first season.
And I think the focus on Emma is a red herring, the killer doesn't care about her, he knows she is the "main" character and that the other characters (particularly Audrey) revolve around her.
I think there is more to it than that, but that is my theory for now.
