I don't think Jack truly loves her. I think he is just looking for someone to save, but Kate has a mind of her own and she's also a liar so that will drive Jack crazy in the end.
Jack is a sweetheart and that is what draws Kate into him, and i think he is gorgous...But if i were Kate, Gosh, i would totally utalise her climbing skills and climb things all day, and occasionally see Jack
I can only hope that Jack and sawyer both come to there senses and kick that s h i t in the dirt. she is everything that is wrong with women. Even evangeline thinks so. Kate is a hussie!
