A thought: Could Jessica be behind the fakery?
It makes a lot of sense if you think about it, and look at the people she talks to and the conversations she overhears:
- In ep1, she has that chat with her mother that she doesn't have anywhere else. Coincidentally, Natsuhi becomes the major driving force for the events of the next day. Was she recruited to play that role?
- Hears about the Halloween stuff in ep2, is part of the group suggesting a party for Maria, and what do we get?
- Obviously knows more than she's telling in ep4. She could very easily know how her "death" would appear if she was planning to fake it.
- Is shut out of a lot of conversation and mobility by Erika in ep5, and is consequently stuck with the cousins. Who is the First Twilight?
- Goes and approaches Kyrie in ep6. Kyrie joins the FT fakers.
I'm just sayin'.
