My answer is Kate, because, we start to see "James" instead of Sawyer sometimes in S4 with Kate.
Kate looks so false with Jack.

Ummmm hello??? He became a completely different person in S5. It was ridiculous how changed he was...

I know and thats why its my least favourite season for him (and overall actually), I wanted the old Sawyer back the one that we all grew to love so much! He didn't need changing.

the only reason who makes me hate sawyer :(:(

I hated seeing him like that. They completely changed his character and forced him and Juliet on the audience.

Kate with Jack was insecure and even pathetic at times, but James with Juliet was a totally different person, a guy who sniffs flowers and wears glasses. And it was painfull to watch.

He isn't his real side.

Neither. I don't think. I don't like him with Juliet, because I hate her. So it doesn't matter. and Kate shouldn't be with Jack.

sawyer and julliet were pretending to be somebody they are not with eachother. the funny thing is julliet is my fav lady charcter and sawyer is my fav male charcter but they don't work well with eachother !kate is not her self with jack so i think kate and sawyer are themselves with eachother and jack and julliet are basicaly the same people !
