Again I ask did you see Ellen at all? If you did then that's the ending. That scene with Tigh in the water is the final scene in this episode. So if you saw that you're good!

I don't know what's up with Kara. Haven't ruled out her being a cylon. I've always had a theory that there were 13 cylons instead of twelve - symmetry with the 13 tribes of kobol and the lost 13th colony and all that. We'll have to wait and see!

Yeah it's a difficult show to process at times. (In a good way, I think!)
