Stowaway (Fringe)

"Stowaway" is the 17th episode of the third season of the American science fiction drama television series Fringe, and the 60th episode overall. It followed the Fringe team's investigation into a woman, Dana Gray (Paula Malcomson), who repeatedly but unsuccessfully tries to commit suicide. Meanwhile, Olivia continues to serve as the host for William Bell, to the dismay of most of her other team members.

The episode's story was written by Akiva Goldsman, Jeff Pinkner, and J. H. Wyman, while Danielle Dispaltro contributed its teleplay. Charles Beeson served as the director. Along with Malcomson, "Stowaway" featured a guest appearance by previous Fringe actor Seth Gabel. Though Leonard Nimoy had recently retired, the writers still had storylines involving his character, leading to their decision to have Bell possess Olivia's body.

"Stowaway" first aired in the United States on March 18, 2011 to an estimated 3.8 million viewers and a 1.3 ratings share for adults aged between 18 and 49. This was the series' lowest ratings share for adults up to that point. Reviews of the episode were generally positive, as multiple critics praised Anna Torv's Nimoy impression as well as Joshua Jackson's reaction to it.
