Tricia Helfer as Number Six in ‘Battlestar Galactica’

Yes, Tricia Helfer is supposed to be a robot (of sorts) here. Helfer, as Number Six (on rock, in red bikini) chats with James Callis (as Gaius Baltar) in the third season of Battlestar Galactica. This was the episode "Torn," which aired on November 3, 2006. If we're reading the episode guide right, this moment turned out to be a hallucination.
