On tonight's season finale of Fringe - "There's More Than One of Everything" - someone "with close ties" to the Fringe Division is attacked. Meanwhile, ZFT bioterrorist David Robert Jones returns and Walter mysteriously disappears. The season finale features Leonard Nimoy of Spock of Star Trek fame as Dr. William Bell. Fringe co-creator Roberto Orci previously revealed that Nimoy's character will return this fall for an extended arc, in at least two episodes, and is going to be "the beginning of the answers to even bigger questions." In an interview, Nimoy described the final scene of the episode, which he shares Anna Torv, who plays Olivia.
"It's very brief, but I think interesting, entertaining and there's enough given in the scene to whet your appetite, that you'll want to see more of this relationship and what it's all about. You'll want to know what it is he has in mind with Olivia, what he wants or needs her for, why he wants to see her, what their past history is about and where they're going together."
