Y'know. I swear there was a "It's not that simple" comment by Jack in the (rather good) Jack/Kate scene. He said something like "you can't..."
Damn, I need a transcript - she was asking him about what they told him and he was trying to find the words, but then just seemed to get confused and give up.
Jack has gone down in my estimations a little to be honest, I can understand his pain at seeing Sawyer and Kate in an embrace, but he's been rather selfish - however we're still missing a piece of the puzzle and, although I may be the only one, I'm glad he's staying....AND JULES!
