After my extended discussion/meta last week, I figured I should post a follow-up.
As I suspected, they were being overdramatic with the trailer. They did reveal who Adam is (and it's not Lucas, unless they decide to pull a double twist, which I doubt), but everything else is still on the table. And since this was the winter finale, and no one knows if the show will get picked up for another season, this is a good time to make that reveal. So I'm ok with that.
I have thoughts on the show, but I'm still too wired to properly articulate them. Maybe later today/tomorrow I can be more rational about it.
