When Charlie dropped off off Nick Lane’s file at the end of “Bad Dreams”, it contained some of the articles that he had posted on his wall. At the top of the pile was “Doppelgangers Among Us”.
This takes on a whole new meaning after the season two premiere “New Day in the Old Town” where an insta-disguise device can turn the owner into a doppelganger of anyone he plugs in to. Charlie has already been taken over by a soldier from the other side.
Since this notion was established in season one, it’s fair to assume that anyone from the other side has had the opportunity to use this device. So did Olivia meet the real William Bell? And who on our side may have been a doppelganger from the start?
