I thought the show was about discovering one's humanity and that theme worked a lot better with Amanda than soul-sucking, self-serving, egotistical Jessi.

I thought exactly the same!! That's the reason I said that I was sure Jessi/Kyle wasn't a true possibility. Maybe the writers changed their mind because all the Jessi/Kyle fans? I can't think of another reason.

Actually, I think they lost the focus of the show and not just because Kyle's love life, but the mythology started to get too complicated. Like they were playing X Files or something... I don't know if I'm making sense here.
