Plot


Sarah advises Cosima not to get involved with Delphine but Cosima thinks that if they are going to get past their monitors, then they have to engage with them. Sarah tries to get Cosima to understand and brings up Alison’s situation about how she assaulted her husband thinking he was her monitor and now they’re at a couple’s retreat trying to repair their marriage. Cosima insists that her situation is much different. Sarah scoffs, “Right, 'cause you’re such a brilliant scientist.” Cosima replies that it’s because Delphine has no idea that Cosima knows Delphine is her monitor. Sarah pleads that Cosima stay away from Delphine.
Helena is struggling to wake up. A man, whom Helena recognizes as Tomas, drips water on her face. Helena asks where she is but he shushes her and tells her, “You’re getting stronger.”



Tomas asks why Helena didn’t kill Sarah, and Helena quietly says that Sarah is different from the others. She thinks she and Sarah have a connection. Tomas insists that their “connection” is nothing. Helena tells him about Sarah claiming that Helena’s not the original. Tomas violently snaps at her, asking her how she could believe such a thing. Helena cowers and apologizes. Tomas suggests that they can use Sarah to find the other clones and Helena admits that she’d like to see Sarah again. Tomas grabs Helena by the hair and tells her that “it” will say anything to justify “its” existence. Helena promises to be strong. The next morning, Helena steps out, determined to complete her mission.
At the apartment, Sarah tells Paul that Beth figured out there were nine of them and claims that so far, she has only met Alison. Sarah assures him that Alison has been with her husband since high school and so he cannot be her monitor, but Paul is not convinced. Sarah asks him whether Olivier is on to them. Paul reveals to her what Olivier told him- someone is killing the test subjects. When he asks her if she knows anything about this, Sarah pretends that she doesn’t. Paul finds it strange that Sarah doesn’t look worried about the fact that someone might be trying to kill her and she admits that she is scared. Sarah tells him that needs to see her daughter. Paul instructs her to take his car, in case someone is tailing her, and hands her his car keys. In the garage, as Sarah is about to get in the car, Helena walks up, scaring Sarah. Helena swears that she’s not there to hurt her. She just wants to talk to her.

As Art is studying the evidence, DeAngelis joins him, complaining that “Beth’s” paperwork is a mess and that the fingerprint results aren’t even there. Art tells her that they ran the fingerprints but they were not a match. DeAngelis points out that even if the prints had no match, the results should be on file. Art suggests they have forensics pull take fresh prints to be processed again.
In Neolution, Olivier is on the phone with someone who tells him that there’s a problem. The person is Leekie, who goes over Sarah/Beth’s medical reports and concludes that it’s not Beth after all. Olivier asks him which one she is if not Beth. Leekie tells him that it’s none of Olivier’s concern and orders him to bring “Beth” in.
Sarah exits the diner, on the phone with Cosima. Sarah assures her she’s not going to give Cosima up, but Cosima wonders that maybe they should tell Olivier everything. A shocked Sarah points out that Cosima was the one who said they’d terminate if they came to know that their subjects are self-aware. But Cosima thinks that their creators, having a tremendous investment in them, would protect them. Cosima asks if Sarah’s heard of Dr. Aldous Leekie, the poster boy for “Neolution”. Sarah tells her about Olivier’s club “Neolution” and Olivier’s supposed “tail”. Cosima explains to Sarah about Neolution and mentions the lecture by Leekie she and Delphine attended. This annoys Sarah since Cosima promised to stay away from Delphine but Cosima counters that she never agreed to that and a frustrated Sarah hangs up. Cosima is getting ready, going through her clothes when there is a knock on her door- it’s Delphine. Cosima opens the door for her and hurries off to get dressed.
At his apartment, Paul gets out of the shower to find Olivier waiting for him. Olivier asks him where “Beth” is. Paul claims she’s with “Christine”. Olivier is irritated since Paul was supposed to keep a close eye on Beth but Paul replies that he couldn’t force her. Olivier reveals to him that his subject, “Beth” is an imposter and has been killing the test but Paul acts clueless.



Back at the restaurant, Leekie asks Cosima and Delphine apply to the Dyad Institute. Cosima is not so sure about it but Leekie urges her to. Leekis claims that he can tell Cosima has a unique perspective but Cosima is not convinced, and replies with a hint of hostility. Delphine listens on, careful to stay out of the argument.
As Sarah and Felix are leaving, Siobhan’s hands over the photo album to Sarah and tells her that she understands if Sarah has to go back in the past to move forward. Mrs. S. vows to keep Kira safe, just as she once did Sarah. Grateful and finally understanding how lucky she is to have Siobhan in her life, Sarah embraces her. Olivier hands Paul his phone and orders him to call Sarah. Meanwhile, Sarah is taking Kira up to bed when her phone rings. Sarah answers the phone cautiously. When Paul calls her Beth, Sarah catches on to what’s happening and goes along with it. Paul tells her that he needs her to do something for him. He shouts into the phone: “They know you’re not Beth, run!” Paul lunges at Olivier, but a woman present there stabs Paul with an injection, making him faint.
Sarah and Felix arrive at Neolution. Though they know Paul wants to protect Sarah, Felix in unsure they should rescue him since he told her to run. But Sarah can’t leave Paul as she blames herself for what happened to him. Sarah calls Helena, who has broken into Beth’s apartment and is going through Beth’s things. Helena reminds Sarah that it’s almost midnight, but Sarah says that she has information for her and names Olivier. Helena is unsure, but Sarah tries to convince her that Olivier is more important than a clone. She wants Helena to meet her at Neolution. Felix and Sarah try to get in, but the door is locked. The door opens and a couple exits and Sarah hurries to catch the door. She tells Felix to call Art and tell him everything if she’s not back in 15 minutes.

Olivier holds a knife against Paul’s throat but Paul does not seem too worried as he looks on at the security monitor. Olivier also looks at the screen too, to find the woman accompanying Sarah on the floor, unconscious and Sarah sitting alone, still tied up. Olivier hurries to the room where Sarah is, but when he removes the hood, it’s Helena underneath. He holds a knife to her face and asks her who she is. Helena smacks him face down on the table, holds the knife to his throat and orders him to show her tail. As he shows her his tail, Helena tells him she has a message from Tomas, grabs his tail and cuts it off! Paul watches this on the security feed and sees Sarah running back, wearing Helena’s jacket. Sarah runs up to him and starts to untie him.

Cosima stares at the Dyad business card, deep in thought. Delphine thinks that working for Leekie would be the opportunity of a lifetime. Cosima leans in and kisses a stunned Delphine. Cosima thinks that she made a huge mistake, but Delphine insists that although that’s not the case she has to go and hurries out.
