SPOILERZ SPOILERS SPOILERZZZZ
That was a great final episode. Yeah so it turns out there wasn't any GREAT mystery - Kara wasn't actually Daniel, she was just an Angel. And the whole Opera house thing only applied to a very specific situation where Hera would be in danger. I agree it was basically the best they could've done given the sheer weight of the MYTHOS at this point. I kind of saw the whole FINAL TWIST as the episode was wrapping up but it was still a coo ending. I guess it makes sense that a show all about cycles starts with a great premiere (33, first ep of season 1 i mean) and ends with a great finale.
farewell... sweet Galactica....
WHY SO SERIOUS HAHAHAHHAHAAHAHAHAHAHAHHAHAHAHHAHAHAHAHAHAHAHAHHAA
