Did the Submarine ever actually leave the Island EVER? In the episode Through the Looking Glass (reference to Alice in wonderland, where a portal takes her to another place)the Looking Glass station has a pool big enough to dock the Sub in. It is even mentioned in this episode or the one prior, can't remember who said it. So, could the Looking Glass be a place where people are teleported to and from the Island without them knowing. Could they be given their sedative and then taken to the Looking Glass to be teleported to Ann Arbor, Portland or wherever and vise versa??? Just one of my crazy theories.
