"Subject 9 " is the fourth episode of the fourth season of Fringe.


Olivia uncovers a dangerous force that may be connected to past experiments with Cortexiphan. The investigation forces Walter to leave the lab for the first time in years and travel to Massive Dynamic to examine old case files. Walter struggles with his emotional state as he confronts the demons of his past.


Olivia Dunham experiences a strange disturbance in her home that creates a brief time distortion and attracts metallic objects it before it dissipates. After explaining this to Walter and Astrid, she and Astrid return to her home to examine the area, where the disturbance occurs again. Walter, observing this from his lab, surmises the effects are similar to one of his Cortexiphan children

Walter's memory can only recall the child subject as "Subject 9", but Olivia is able to secure records from Massive Dynamic that name the person as Cameron James. While there, it is revealed that, in the alternate timeline, the Cortexiphan trials were stopped after Olivia ran away from experiments as a

Olivia also remembers being experimented on, unlike the original timeline, and the Fringe Division has not encountered the former Cortexiphan children before, as Astrid has no memory of them. It is also revealed that Olivia now shares a much closer relationship with Nina Sharp, who knew her growing up. Walter insists on leaving the lab, the first time in

Olivia offers to treat Walter to a root beer float, during which Walter reveals his discovery of the letter and that he came to show Olivia that he is still useful.

Notable Quotes[]

Walter: Claire, will you please man the cameras in my absence?
Astrid: Really? "Claire"? That doesn't even start with an A.

Walter: You have the ability to gather and direct the kind of power we need.
Cameron: How?
Walter: Well, just like in the highway. Once when you were a boy, you-you blew up a toaster oven with your mind because of an irrational hatred of raisin toast.
Cameron: You ever had raisin toast?

Nina: Maybe you can ask Walter if he remembers what group the boy was in. I mean, that may help.
Astrid: Of course. Uh, Walter, did you hear that?
Walter: (on the earpiece) Yes. Her voice goes right into my inner ear and rattles around like razor blades. Of course, I heard her. Tell her to go...
Astrid: He said that he is not sure, but, uh, thank you for the suggestion.
Walter: I-I did not say that.
Nina: Walter has said many things to me over the years, but "thank you" was never one of them.


  • The Observer can be seen, his back to the camera, as the two fishermen pull Peter Bishop out of Reiden Lake.
  • Although credited, Seth Gabel (Lincoln Lee) does not appear in this episode.
  • Olivia Dunham claims she did not meet any other test experiments of Walter when talking to Cameron. Since Peter does not exist in this alternate timeline, it is possible that certain events may or may not have happened. Events centred around Peter have been altered since he was not there, including the letter to St. Claire happening this late in the story.
  • Walter obviously is not the owner of Massive Dynamic since Peter disappeared.
