An older gent walks downstairs to find large amounts of blood all over the walls and doors. He makes a phone call, telling whomever is on the other end of the line that there’s an issue.
And with his newfound freedom, Castor clone Rudy brings a young lady back to his hotel room. She seems a little tipsy and wonders why he’s not in a better room if he’s Special Forces. He blames cutbacks and gets her another drink, then takes her coat. The girl turns away from him and Rudy briefly seems to be Seth, but when she turns back he’s Rudy again. They begin to make out and get busy and Seth creeps out of the shadows. He joins them uninvited, which freaks the girl out. She says this isn’t what she signed up for, but Rudy insists that he and his brother share.
Sarah, Cal, and Kira walk together and discuss current events: Delphine is in Europe dealing with Rachel’s business. Sarah says she needs to call Cosima, but Cal leads them to a nice flat that is his new apartment. Both ladies like the place and Cal is happy.
Rudy wakes Seth (by spitting water in his face) just in time to stand at attention when Paul stops by his hotel room. Seth dresses quickly as Rudy antagonizes Paul by describing his recent run in with Sarah. Rudy doesn’t like the idea of Sarah working with Dyad but Paul ignores this, saying Rudy will be “first.” Then we see that Paul affixes a camera to his head an inch from his eye and asks him logic puzzles. He answers with ease and little stress. Seth, on the other hand, is slightly more frazzled and unsure of his answers, eyes darting side to side as he tries to think of the correct answer. Looks like Paul’s in charge of the mental conditioning of the Castors. Rudy saves Seth from a question he couldn’t think of the answer for and Paul gives them their extraction papers. Rudy doesn’t like the idea of dropping their mission, but Paul insists they go back to base immediately.
Scott visits Felix’s loft to give Cosima another check up. He’s astonished at how great her current health stats are and Cosima says that maybe her improving health is a sign that she needs to get back to a lab. Scott doesn’t trust Dr. Nealon, the man currently running Dyad’s lab, but he thinks much more highly of him than he did of Dr. Leaky. Also, Dr. Nealon wants to meet this afternoon. Felix brusquely tells them to shoo, but not before giving Cosima a new clone phone.
At a soccer game, Alison and Donnie discuss her potential run for School Trustee, shooting daggers at Marci as she gives an interview to what looks like local media. Donnie is worried about how they’ll pay their mortgage, much less for a campaign, and Alison reminds him they can’t sell the house because of the guy they buried in the garage. Donnie walks away to tend to their daughter and Alison is approached by Ramon. He tells Alison that most of his clients are soccer moms and she’s shocked that he’s selling pills at a kid’s soccer game. She tells him she’s clean and he says he’s about to hit the straight and narrow, too, and is going to college. As Ramon walks away, Donnie returns, curious about who he was and Alison replies that he’s an opportunity. Hmmm…
Sarah, Cal, and Kira play hockey in his apartment and have a ball swinging sticks around indoors. Sarah gets a phone call from Art – excuse me, I mean, Detective Bell. He’s just picked up a case from the woman Rudy picked up and after seeing how much the suspects (Rudy and Seth) look like “that Prolethean freak Mark” he thought he should call Sarah. Immediately she asks if one of them has a scar and other other a sketchy little mustache, which Art confirms, and she asks if the woman was hurt at all. Art says she just seems freaked out so far and Sarah wants to know everything Art knows, but he has to go back inside, promising to resume their conversation later. When she hangs up, Sarah fills Cal in on her call. He asks her to stay, knowing it’s futile, and she says she has to go find Helena. She’s pleased that he’s gone to such lengths to make a home for her and Kira and they kiss.
The Army Castor brings Helena in a room full of soldiers and they lay her on a platform and waterboard her. As she tries to recover they take an oral swab and inject her with something. Just before she can be waterboarded again, the smoking woman intervenes, telling everyone that Helena is pregnant. She introduces herself as Dr. Virginia Coady and tells Helena that it might not seem like it, but she’s happy to meet her. O-kay.
Over at Siobhan’s, Felix makes tea for the still recovering Mrs. S. He tries to cheer her up, saying Sarah will come around, but Siobhan isn’t so sure. She thinks she’s lost them and Felix tells her she should do something about it. He gives Siobhan a clone phone and says she doesn’t get to sit this one out so she’d better get to work calling up her dodgy friends who might be able to help.
Cosima and Scott banter but are interrupted by Dr. Nealon’s arrival. Nealon compliments Cosima’s good health and she starts off strong with a solid, “Yeah, I’m as important to you as Sarah’s ovary, huh?” He says hard science requires hard decisions, telling Cosima that even she has had to make some of her own, but she redirects the conversation to Rudy’s escape. Scott asks Nealon about the original genomes for Project Leda, but he says that it’s lost to them thanks to the Duncans. He explains that Leda began as a military experiment under their guidance, but when the military shut them down they were recruited by Dyad and brought their genome with them. He says the Duncans also secretly sourced donors for two lines of clones, a male and female, which surprises Scott and Cosima. Cosima wants to know who these donors are but Nealon says the Duncans falsified records and hid identities to ensure that information was never discovered, meaning both Leda and Castor original genomes are lost.
Art walks with the woman from the hotel and she’s not comfortable just going home knowing Rudy and Seth are still out there. Sarah approaches them and Art tries to get her to go away, but she’s got some questions for the woman. Enter Detective Beth Childs. “Beth” approaches the woman and asks her to outline, again, what exactly happened in the hotel room. According to her, after we saw her withdraw upon seeing Seth join them, Rudy got mad that she wanted to leave as though he was rejecting Seth. She saw them rummage through her wallet and wrote down all of her personal information, and then ripped out a piece of her hair and put it into a bag. Art is none too pleased at Sarah’s latest acting gig, but she says she’s just trying to figure out what the Castors are after because they have Helena. So Art spills a little helpful information: the brothers both have a two-headed horse tattooed on their left forearms.
Alison and Donnie plan a clandestine little meeting with Ramon at the soccer field. When Ramon arrives, we finally understand the opportunity: Alison wants to buy Ramon’s business from him, hookups and clients and all. Ramon is a little skeptical that nice Mrs. Hendrix can handle the drug game, but she says it’ll be a breeze since most of his clients are in her circle, anyway.
Seth paces and agonizes over the logic puzzle that got him stuck earlier. He lashes out and punches a car window (but doesn’t break it), damaging his hand. Just then Rudy calls, saying he’s not going back to base as ordered. Instead, he’s paying a visit to Felix’s loft. Rudy tells Seth that he knows he’s glitching, and Seth confesses that it’s been happening for a week or so. Rudy breaks into Felix’s loft as Seth tells him he doesn’t know what to do about his condition, and Rudy tells him they’re going to “finish the job.”
At Dyad, Cosima speaks to Sarah over the phone about the Castors. She tells Sarah that, according to myth, Castor was a warrior horseman which connects to the brothers’ tattoos (which is a black ops insignia). They’re trained, perfect ghost soldiers, but Sarah wonders why they took the woman’s hair. Cosima says that if they got a follicle they could be interested in some kind of medical testing. Sarah isn’t happy that this information gets her zero steps closer to finding Helena, so Cosima steers her toward another alternative that Sarah doesn’t want to pursue: see Siobhan in order to get to Paul.
Helena has been hooked up to the same eye camera headset we saw Rudy and Seth in earlier and is being subjected to the same kinds of logic questions by one of the army men (and closely watched by Army Castor). Pupok the scorpion distracts her, though, so her first answer is, “Where are these mangoes? I would like to see these mangoes.” The men become impatient as Helena deliberately insults Army Castor (“I saw your brother. He was ugly”), so Dr. Coady intervenes. She takes Helena outside and they’re in an army holding facility of some sort. The dry, arid atmosphere indicates desert, and Dr. Coady says it’s nice at night because she can smoke since the air is clear. She and Helena walk together and we find out that Coady has been a guardian of sorts to the Castors since they were young, even though she never wanted children. Someone brings some food which Coady gives to Helena and Helena scarfs it down. Coady tells Helena that her family sold her out to bring her there, that it was Sarah who gave her up because she’s expendable. Helena doesn’t believe it but Coady presses on, saying she’s not expendable to her – or her boys.
Rudy searches Felix’s apartment and almost finds Professor Duncan’s copy of Dr. Moreau that Cosima is hiding. Then he spots Felix’s art corner – which includes a painting of Sarah.
Speaking of Sarah, she stops by Siobhan’s and is greeted by Felix. He says Siobhan has three broken ribs and, judging by her total honesty, a possible concussion and warns Sarah to take it easy on her. Sarah gets straight to it and says she needs to get in touch with Paul and Siobhan says he’s gone dark as he’s gotten what he wanted. Sarah prepares to leave but Siobhan stops her, saying Cal is doing her no favors pretending that he, Sarah, and Kira can be a family and live safely there. She urges Sarah to take Kira and go someplace safe but Sarah, as usual, doesn’t want to listen to her saying that she won’t take advice from someone who sold her sister. Siobhan says that she regrets that but knows that they are all in the dark about what Castor is all about which makes for terrible fighting conditions. She recalls picking up with the kids and leaving when Sarah was young, because that was the right thing to do to protect the children. Sarah seems to be considering it now.
Out at Ramon’s car, Alison and Donnie peek into their new lives: $80,000 worth of narcotics, from pills to purple drank. Ramon says he’ll hand it over for $25K, because he’s built up a brand, and Alison says they’ll take that as well as his client list for $32K. He tries to get her up to $35K but she insists she’s firm on $32K and will pay cash, causing Donnie to panic. They step aside to talk and he’s worried about where they’ll get that money from. Alison says they’ll borrow from their retirement fund because this is much-needed income. And besides, her new, very loyal customer base will double as her voter base, making her election bid practically a shoo-in.
While unpacking, Cal hears a door open and a dog barking outside. He steps out to investigate and, finding nothing, goes back inside – but Paul is waiting for him, gun drawn. Paul tells Cal to turn around and put his hands on his head so that he can pat him down. He asks Cal why Sarah went to see Delphine at Marion Bowles’ and he’s like, “Why don’t you just ask her? She does want to talk to you.” Returning his gun to its holster, Paul warns Cal that none of them know what they’re getting into. Cal rubs it in that Paul’s infiltration of Dyad was a failure, so Paul reminds Cal that he used to be a weapons designer and war profiteer. Cal asks where Helena is, but Paul changes the focus back to Sarah. He says Sarah needs to take the deal that gives her time and space and give it up, because if she keeps coming it’s going to end badly for everyone.
Sarah and Kira turn up at Felix’s and they discuss possibly moving in with Cal. Sarah runs a bath for Kira as Kira brings her favorite toys into their fort. Sarah misses a call from Cal with her phone in the other room, and as Kira climbs to another segment of the fort she is startled by Rudy, sitting quietly with red Xs drawn over his eyes. Sarah calls for Kira as the bath is ready and comes out of the bathroom to find Rudy sitting with a gun held to Kira. He wants to know if Sarah has the tissue samples of the Castor original but she maintains she doesn’t know anything about that. He threatens Kira some more as Cal arrives downstairs. Seth stops him asking for some change allowing Cal to notice Seth’s horse tattoo and remember Sarah’s phone call earlier. He cold cocks him but doesn’t know Rudy down, and Rudy pulls a knife, saying his brother won’t be disturbed.
As he paints little red lines on Kira’s face, Rudy tells Sarah he can’t leave without answers, causing her to bring up Seth. Downstairs, Seth’s having an episode and Rudy wants to know how Sarah even knows about him. As Seth’s distracted by the voices in his head, Cal reaches for a blunt instrument, but Seth falls to the ground himself. His cries reach the second floor and Rudy panics, nearly shooting Sarah and Kira. He leaves and Sarah “locks” the door, and Rudy finds Cal standing over Seth. As Seth groans in agony, Rudy holds Cal at gunpoint as Cal tries to calm Rudy down. Then Rudy shoots Seth twice in the chest and the brothers share an oddly touching moment as Seth dies there on the floor. Cal is shocked by all of this but Rudy just takes the notebook in Seth’s hoodie pocket and runs away.
Back at Siobhan’s, Sarah talks Kira through a new life on the run as they pack to leave town. Felix tells Sarah she’s a good mother for doing what she’s doing, and Siobhan, Kira, Cal, Felix, and Sarah all make their respective goodbyes. Siobhan says her people will get them out of the country and warns him not to contact hers until they’re out. It becomes clear that Cal is taking Kira away to Iceland and Sarah promises Kira that she’s going to fix things and they’ll be together again. Now, Sarah says, they have to get Helena and the only way to do that is to go to the one they know, Mark.
In a hotel room, Gracie wakes and hears Mark in the bathroom. She calls for him but he tells her to go back to sleep. In the bathroom, Mark uses a blowtorch to burn off the horse tattoo on his left forearm, biting on a towel to muffle his screams.
The Questions: What is Sarah’s next step to get to Helena? Will Helena be susceptible to Dr. Coady’s half-truths? Who’s going to find Seth’s dead body in Felix’s lobby? Are Sarah and Siobhan friends again? And are the original Leda and Castor samples really gone forever?
