As much as I hate Juliet, something tells me that she might turn on the Others and become part of the Losties. When Jack mentioned the look on her face when the submarine blew up and how she wants to go home as much as the rest of them do, I think that really triggered her emotions. I think the more time she spends with the Losties, the more she'll second guess which side she should really be on.

What ever happened to Goodwin, the Other that Juliet was screwing around with? Did he die? And if so, who killed him?
