I've been trying to work out the details of my theory which I'd initially made before I'd read Episode 5 (initial posts here
I'll have to fix the sin and maybe a couple other things based on episode 5, but it still seems mostly okay.
I ran into a few questions while working out details that I don't think have been settled yet.

As for the rest of the episodes, I think I will have to replay them before I can fully complete any details on them. I do have some thoughts, though.
