WARNING: "LOST" SPOILER!!!
YOU HAVE BEEN WARNED.
Apparently the island has something against women. In particular, women who start relationships with the male castaways (Sun and Rose are safe because they were already married to start with). What gives? The second a girl shows interest (real or fake) in a guy, they kill her off. (I *get* that there may be totally non-storyline-related reasons for this). I think I'm starting to get it now: the island is a bitch. Literally. A jealous, man-hungry bitch.
Claire, I think it's smart of you to keep your distance from Charlie. Don't fall for him. Just, whatever you do... don't. And Kate, I would totally back off from Jack. Let's just not be foolish here, KWIM?
