I'm a little disappointed with how they've written him so far this season. Last season, he seemed to turn the corner, at least in terms of maturity, after being held hostage in that country. So far this season he's been the same sarcastic, petulant child. he was during season 1 and 3/4 of season 2.

However, with this last episode, you can see some of the stuff behind his attitude and what helped shape him.
