I've watched this episode 3 times in the last 2 days trying to pick up some clues (Please don't make me watch it again!) It seems to me that the camera crew came running into the argument. The first thing we hear is something from Sue like, "Colleen said you said that you weren't alligned with us!" I even watched it with Closed Captioning so I could get the whole fight in. I remember Colleen commenting that she thought Kelly was being a double agent. So if she went to Sue saying anything her motive probably was:
** to try and pit the alliance against eachother. If TA didn't know what Kelly was saying about them maybe they would try to vote her off instead of Colleen.
I don't see how that is really backstabbing Kelly. To backstab someone you need to have a trusting relationship with that person-- and I think at that point Colleen didn't trust anyone on that Island.
I really don't understand Sue's reaction -because from what I gathered from Rich & Kelly's discusion, it sounded like TA HAD agreed that Kelly should act as a sort of Double Agent with the Pagongers. Kelly was right in one of her confessionals when she said, "All I did was lie when I said I wasn't in an alliance. Sue has done the same thing in tribal council. Now all of a sudden I'm a bad person for it?"
Excuse me for the tangent-- but the whole argument is confusing to me.
