role of Number One/Theresa Halloran from the episode "Lines of Communication" onwards. During the filming of "Heroes and Demons", Monaghan's stunt double was Patricia Tallman. The duo went on to work together on Babylon 5 with Tallman playing the character of Lyta Alexander. They didn't initially recognise each other on the later show because of the costumes they wore in the Voyager episode. Monaghan was also considered for the main cast part of T'Pol in Star Trek: Enterprise.
