had spent the most time with Bell. She took further advice from the show's dialect coach and reviewed footage of Nimoy's previous work, though eventually she decided to jump right into the role. Noble later commented "I think the solutions she came up with – taking the essence of the man, playing with the eyebrows, simulating the voice — were really smart. We had a lot of fun doing it." Executive producers J.H. Wyman and Jeff Pickner were both impressed with Torv's take on the role, with Wyman stating that it "just transcended all our expectations", while Pinkner noted that Nimoy himself was "the most proud and most impressed" with the outcome. Actor Joshua Jackson found her performance "so creepy". He explained, "In the episodes, you see I can barely look at her. I think it ended up being a good way to play Peter’s reaction to Olivia, but it was born out of the fact that when that voice came out of her, I was like: ‘Oh, that’s just wrong!'" Pinkner confirmed in an interview with TVline that Bell's appearance would last for "a couple" episodes, and also warned that "cohabitation is not as benign as William assumes it is", a reference to problems Bell would soon have in Olivia's body. The possessed state of Olivia has led viewers to refer to her as "Bellivia". "Stowaway" featured a guest appearance by actress Paula Malcomson, her first and only time on the show to date. Guest actor Seth Gabel had previously played just one version of character Lincoln Lee, who existed as the head of Fringe division in the parallel universe. "Stowaway" marked the first appearance of the character from the prime universe. Gabel described his prime universe character as someone who works for the FBI, "but has no idea about Fringe Division. He's more of a desk jockey [who] eventually comes to believe there is much more than reality suggests". Executive producer Jeff Pinkner described Lincoln's introduction as "insanely fun -- the characterization Seth has created just makes you smile". Gabel also indicated the new character would likely return for more episodes. As with other Fringe episodes, Fox released a science lesson plan in collaboration with Science Olympiad for grade school children, focusing on the science seen in "Stowaway", with the intention of having "students learn about magnetism and how magnets can be created and demagnetized."
