Plot

Another malfunction causes Cameron to believe that she is actually a human from the future named Allison. Sarah accompanies her pregnant landlady to the hospital. Ellison continues to contemplate Catherine Weaver's job offer.

Kacy has complications with her pregnancy and Sarah takes her to the hospital. There she meets the baby's father, a LAPD detective. Meanwhile, Cameron has yet more problems when she draws a memory blank while shopping for groceries. She takes up with a young street person, Jody. While together, Cameron has a series of flashbacks recalling her interrogation of a young woman, Allison Young, who resembles Cameron to a tee. We learn of the reason for the lookalikes and Cameron's one-time mission. Elsewhere, Agent Ellison is still considering Catherine Weaver's job offer and asks his ex-wife, also an FBI agent, to do a background check on her.—garykmcd

The episode opens with an unknown woman running along a dark tunnel, forcing her way through a door before being snagged by a large net. Immediately we cut to Cameron, who was apparently remembering this (since I doubt terminators day-dream).

Cameron is in the car with John, who drops her off at the supermarket while he hits another store. Sarah drives by pregnant neighbor Kacy just as she is experiencing stomach pain and takes her to the hospital.

While pushing a car through the supermarket Cameron has another flashback and while in a daze she knocks over a bunch of produce. The police are called in and during that conversation she flashbacks (or is it a flashforward?) to an interrogation by a skinless terminator. Cameron tells the terminator her name is "Allison, Allison Young."

Cameron ends up in custody where shes befriended by a blonde named Jody. Cameron introduces herself as Allison. We cut to the hospital where Kacy is having some tests done to see if the fetus is healthy. Sarah decides to stay with her.

John goes to the supermarket and finds out Cameron was taken by the cops. Cameron and Jody are released at the same time and, after seeing her wad of cash, Jody invites Cameron to join her.

Meanwhile Kacy and Sarah appear to be bonding mother to mother-to-be and Sarah tells the story of John's birth. A Trevor comes into the room and Kacy makes it clear to Sarah she would like her not to leave her alone with him. John is searching the streets for Cameron and Jody.

Ellison has a meeting with Weaver, and he makes it clear hes interested in her job offer, primarily because it will provide the opportunity to go after some terminators. Weaver tells him she thinks humans are imperfect and intimates that she does not share his believe the machines are evil.

We're back to back-story Cameron, who is in a dungeon-like room being fed a plate of rough-looking food. Cut to Cameron and Jody, who is relaying a little of her story as the two appear to be connecting. Just then a dude arrives and begins yelling at Jody, followed by a straight right hand to her jaw. The guy then grabs Cameron, but instead of ripping his arms off and beating him with them she the guy all her cash to get rid of him. Whaaa?

More friend-building between Cameron and Jody as the two check into a halfway house, and Cameron lists her name as "Allison Young." Ellison meets with his ex-wife, fellow-fed Lila, looking for some background info on Weaver.

More back-story interrogation of Cameron, which is cut together with a present-day visit by a halfway house counselor. Similar questions are asked by terminator/counselor, and the biggest revelation is hearing Cameron describe a father, a mother and a sister, the latter of which gave her a bracelet the terminator is asking about. She tearfully tells the terminator a previous birthday party never happened because "everyone was dead." We then find out in both interviews that Cameron is from Palmdale.

Back at the hospital Kacy tells Sarah that Trevor is the baby's father and that he freaked when she got pregnant.

The phone rings in a house somewhere and a young woman answers. "Mom?" Cameron asks from a phone in the counselors office, "its me, Allison." The counsel gets on the phone and we confirm that the woman is a Mrs. Young, and she is pregnant, presumably with yet-to-be-born Allison. (Or is it Cameron? My head hurts.)

Trevor brings the ladies some food, and seems like a pretty solid guy as we learn that hes an LAPD detective. A nurse tells them the baby is healthy. Lila tells Ellison that Weaver checks out.

John finally finds Cameron at the halfway house. When he confronts her she has no idea who he is and doesnt recognize the name Cameron. He tells her shes a machine and that her "chip is messed up," which prompts another flashback. In this one Cameron is running from something, past cages with humans and animals and eventually leaps off the edge of what turns out to be an aircraft carrier and into the water. Immediately shes grabbed by a net.

Back at the halfway house Cameron ends up shoving John into a way before security makes him leave. Flashback Cameron is thrown on the floor, looks up and sees . . . another Cameron! This new Cameron tells her (in the same voice as the skinless terminator from the interrogation) that "you shouldnt have run."

New and old Cameron talk, and it becomes clear that this terminator has replicated the girl named Allison. (But if our Cameron isn't Allison, how could she have been reflecting on memories that occurred when Allison was by herself? Man, my head hurts.)

Cameron tells Allison that shes very brave, which "must be why John Connor chose you." Cameron tells Allison that the humans are all going to be killed, but that "some of us don't want that. Some of us want peace." Cameron tells Allison that she wasn't just chosen by John Connor, but by "us" and demands to know where his camp is.

We're back in the counselor's office and Cameron tells the counselor she is a machine programmed to infiltrate of the human resistance and to find John Connor. The counsel then asks Cameron what she will do when she fins John Connor: "I'm going to kill him and hang his head on a pike for all to see." (Oh, crap.)

Cameron starts asking Jody questions about her life, sounding very much like the flashback interrogation. The counselor calls the authorities about Cameron's threat, but when they arrive the girls are gone. Ellison meets with Weaver (and her young daughter), telling her will take the job.

Cameron and Jody arrive at a house where Jody claims to have babysit, while John sits in his car nearby. As Jody's stories from earlier unravel, it becomes clear this house belongs to Jody's parents. Cameron keeps interrogating Jody, and we flashback to the Cameron/Allison meeting where Allison had lied to Cameron in an attempt to expose her as a terminator.

Cameron grabs Allison by the throat and kills her, saying that she has already helped her get to John Connor. So apparently our Cameron isnt one of the good guys after all. Fooey.

Back in the house Cameron starts getting all Camerony on Jody, accusing her of lying and grabbing her by the throat. John comes in to find Jody lying on the floor, still alive, as he and Cameron flee.

Kacy tells Sarah that she was actually the one who freaked out when she got pregnant and that she was scared of raising a kid with the cop. Sarah tells Kacy she lied to her earlier about Johns birth, that she was alone when he was born and that she will be there to help Kacy.

Our last scene is John and Cameron driving together, with Cameron beginning to copy some of Jody's fabricated bio as the episode comes to an end.
