Leonard Nimoy Returns to Fringe

Despite retiring from acting earlier this year (for who knows how many times), it seems that Leonard Nimoy just cannot stop scratching that itch. Christopher Lloyd (Back to the Future) revealed at the Star Trek Convention in Rosemont, Illinois that the actor co-guest stars with him in an upcoming episode of the series. Nimoy's William Bell character apparently died in last season finale of Fringe, willing everything to Dr. Bishop so should be an interesting trick if the character is actually returning. If he does, fantastic, but I can't help but wonder if the character might have a part in the episode but not necessarily in a way that requires an actor to play him.
