The Human Kind

"The Human Kind" is the eighth episode of the fifth season of the Fox science-fiction/drama television series Fringe, and the show's 95th episode overall. The episode was written by Alison Schapker and directed by Dennis Smith. Plot Olivia (Anna Torv) is still worried about the effects of the Observer implant on Peter (Joshua Jackson), and succeeds in getting another one from their ally Anil (Shaun Smyth) for Walter to study. Peter is still trying to track down Captain Windmark (Michael Kopsa) to avenge killing his and Olivia's daughter Etta, using the precognitive abilities of the implant. He flees Etta's apartment just before Windmark and his associate arrive, and heads to New York City to put his plan into motion. Walter frees another video tape, this one directing him to the city of Fitchburg, 50 miles to the west of Boston. The tape instructs them to recover an electromagnet. Olivia, after giving the implant to Walter (John Noble), goes off alone to recover it, anxious about Peter's whereabouts. As Olivia travels, Walter and Astrid (Jasika Nicole) discover that the implant can transform the human brain into one of advanced intelligence but at the cost of losing all emotions if left in too long, and let Olivia know this.
