I'd have loved to see Kara try to get religious guidance from Cavil before finding out he's a Cylon. It would be horrifying and creepy. I'm especially imagining her trying to get help from him for her guilt over Zak's death and her conflicted feelings over Lee. It would just be bad, but possibly in an interesting way.

That would be so creepy cool.

I've always liked that Kara's faith was private and personal. It's interesting to imagine her then going to an official religious figure for any reason, but certainly more so for something so personal as her conflicted feelings over Lee and Zak (and possibly Sam too).
