Well...this is speculation, but speculation in light of the last episode, so I'll do the whole "highlight to read" thing down below when I get to my actual guesses... just in case (as this IS the non-spoilers thread) ... The one who dies has to be a leader to fulfill the "dieing leader" prophesy. This would lead me too to a conclusion that MAYBE this person is the one to find earth? ... but then I think about it and no...the "dieing leader" dies before he/she reaches earth according to the scrolls. I also think that Baltar officially negated Laura's claim to be the leader after he saved her. she isn't dieing anymore, and I don't think that they will kill her. Besides, she has to live so that she and Adama can go off and be happy on earth together. ^_^ So! my guesses! 1)Baltar is the leader who will die in the quest for earth. 6 has said OVER and OVER that he "is the chosen one" and we ALL know how THAT role turns out...*nudgenugdewinkwinkAnakincough* 2) Kara is the cylon. This is my guess after the last episode. She is one of the lost 5 and DEFINITLY has knoweldge as to where earth is. 3) As for who will find earth? ... That's a good question and I don't think I'm very confidant in this answer, but I think (as much as I would LOVE it to be Bill) it'll be Lee. I've thought that Lee is going to find earth ever since the whole "ARROW OF APOLLO WILL LEAD US TO EARTH" thing. can you say "foreshadowing"? Sure ya can... ULKESH! Am I close??
