Very nice theories! I absolutely agree with your idea for the second killer; there is are a lot of things that can be explained that way.
SPOILER ALERT FOR EP 3 (just in case)
Specifically, I don't see any other way to explain the scene of Shannon's resurrection. Kanon is an other candidate because Jessica hears him at the end, when she's blind, but I think it's more likely Shannon could pass her voice's as Kanon rather that Kanon masquerade as Shannon.
I'm also curious about the number on the door.
