So we still don't fully know what happened to Jack during his week with Others, but it seems like Ben didn't let him into the loop very much. He didn't know why Juliet was sent back to the Losties camp with them until she told him he mission, and when Juliet mentioned the underwater hatch and how it's blocking the radio transmission, Jack was like 'what?'. It seems to me that the idea of Jack being compromised is turning out to be false. Any thoughts?
