I really don't want the triangle to be Kate's only story. Meaning, the only manifestation of her "psychological" issues. If all her story really comes down to is, 'Who should I date, the bad boy or the good guy, because they'll define who I am,' then her character is looking for nothing more than outside validation.

But if by "psychological thing" you mean she struggles with her self-worth, and it happens to manifest itself in the men she chooses, then yeah, maybe it's more complex, and I think that's what they were going for in WKD (which I agree, is probably her best episode character-wise). But unlike Sawyer, Jack, Hurley, and others we haven't seen any significant change - she still seems to be torn between the two same guys five years down the road. Just when I thought they gave her something where she stood apart from the men in Aaron's storyline, it still came down to Sawyer anyway. Her motives weren't as humanitarian as they seemed - she kept Aaron because Sawyer wasn't there.

Sorry, didn't mean to go on a rant there, LOL. I was just kind of pissed when I watched the Pilot and Tabula Rasa - that her character didn't amount to more than that, and that they've written her keeping her feelings so close to the vest - not knowing how she feels, or what her motivations are - it's made her hard to identify with, for me at least.
