Okay here's a question ---
* On the one hand, if Nimoy/Bell do return for an episode, and the producers manage to keep it under wraps completely .... surprising the viewers with absolutely no warning in advance, THAT would be wicked cool in my opinion. Quite a coup and an "awwww SNAP!" moment for us devoted Fringophiles.
* On the other hand, if Fringe wants to boost it's ratings again with a Nimoy bump, then wouldn't they be advertising it fairly heavily right about now?
