I think we might find out that Jack and Juliet did share some kind of intimate moment back in otherville. Now not necessarily a wild week of island sex, but something that brought Jack a lot closer to her. Lovey dovey things that would make him say stupid stuff like "she is under my protection" instead of just rationally talking to Sayid and trying to explain stuff.
I don't think Jack is working with Ben. Nope. He is just the same old dumb school boy he has always been. He has book smarts, great doctor skills, a natural desire to help, but underneath it all he is a just a little boy that thinks his Dad never loved him.
