Fringe: Immortality

"Immortality" is the 13th episode of the third season of the American science fiction drama television series Fringe, and the 56th episode overall. In the episode, the Fringe Division of the parallel universe investigates a series of deaths caused by flesh-eating "skelter beetles", unleashed by a mad scientist (Alon Abutbul). Abutbul, Seth Gabel, Kirk Acevedo, Philip Winchester, Ryan McDonald, and Joan Chen appeared as guest stars. The episode was written by co-executive producer David Wilcox and story editor Ethan Gross, and was directed by filmmaker Brad Anderson. "Immortality" first aired in the United States on February 11, 2011 to an estimated 3.7 million viewers, a 12.5 percent decrease from the previous week. Time shifted viewing led to an addition of 64 percent to the week's original ratings, but lead actor Joshua Jackson still expressed concern for the show's future, urging fans to watch the series live on Fridays. Television critics viewed the episode positively, with one praising it for offering "a creepy case, a great villain, and a pertinent plot twist".
