I think charlie could very possibly be compromised , perhaps ever since ethan first took him, Hes been a very influential character this season effecting ppls actions ever since him helping sawyer nick the guns. this episode he was playing ppl against each other, telling locke to go get desmond to sort out eko, and then helping eko. he manages to get away in time sumhow but we dont know about eko or locke... hmmm. hope ekos alive hes still the best character. maybe now the island can be seen from the outside world, now that the button is gone.
