I just went back and checked the episode recaps for the episode where they discussed Trek. Sure enough, not only do they discuss Trek, but the guy who basically broke the case open for Fringe Division ALSO CLAIMS TO BE SPOCK! And he's the one who connected the dots between The Pattern and Bell. So a man who claims to be Spock also seems to know more about Bell than anyone else. Surely he must notice the similarities between William Bell and the man he claims to be?
