Leekie sets up a meeting with a powerful woman named Marian Bowles, with whom he discusses the living status of Dr. Ethan Duncan. Marian seems to have a strong handle on the clone situation, though we don't learn much about her personal involvement in it. We get the sense that Marian is higher up on the Dyad food chain than Leekie when she essentially orders Leekie to pull in the reins on Rachel and make some strides on obtaining Sarah Manning.
Mrs. S wastes no time in getting to the Dyad Institute to strike up a deal with Leekie. She offers Ethan Duncan's early research on the clones but Leekie requires the authentication of this research by the good doctor himself. Siobhan counters with another offer: Duncan for the Dyad in exchange for Kira's freedom. This deal, however, doesn't include Sarah as Mrs. S believes that Kira deserves a better life than what she's been given. Still seemingly playing both sides of the field, Siobhan calls Sarah to fill her in on her meeting with Leekie. She believes that Rachel has no idea of Leekie's involvement with her mother's murder and the two agree to drop that knowledge bomb on Rachel despite the consequences.
Sarah is reunited with her daughter for a few short moments before she gets a call from Felix and Alison. Sarah rushes to the rehab center to help them with their Vic problem while Felix spikes Vic's tea, knocking him unconscious. As the day goes on, Sarah gets strong-armed into playing Alison at her rehab's Family Day. Consider this scene a throwback to Season One's potluck party at Alison's house where Sarah pretended to play Alison in front of her entire neighborhood. Meanwhile, Alison and Felix go on a mission to hide the unconscious body of Vic and narrowly avoid being spotted by Angie DeAngelis. Our detective sees her informant passed out and bleeding from the nose, which basically negates him as a credible source and saves Alison's secrets, for now.
The biggest shock at Family Day comes when Donnie discovers both Alison and Sarah side-by-side and is flabbergasted by the resemblance. Alison confronts her husband about his involvement in the experiments, but Donnie explains that he was completely unaware his monitoring gig had anything to do with clones at all, but instead was pitched to him as an extended sociology experiment. Poor, sweet, dumb Donnie.
Cosima calls Sarah and fills her in on the Kira stem cell treatment problem. Kira overhears the resulting argument between Sarah and Cal and pulls her own loose tooth out, just for her 'Aunt' Cosima. Just another creepy-sweet moment from Orphan Black. The mother-daughter pair ride off, presumably to bring the tooth to Cosima.
Meanwhile, Siobhan's deal with Leekie comes to a head when Rachel and Paul show up to meet Ethan Duncan and authenticate his early research. For once we see some real emotion from Rachel, including tears in her eyes at the sight of her long-lost father who proceeds to tell his daughter about Leekie's involvement in Rachel's mother's death.
Armed with that knowledge, Rachel confronts Leekie and a Baddie Showdown begins. Leekie urges Rachel to put this whole thing behind her and move forward, but Rachel instead calls Marian. In another switch up, we discover that Marian has ordered a hit on Leekie for his incompetence with the Sarah Manning issue. Rachel, in an act of kindness, prompts Leekie to leave the Dyad and forgo his car and his home in effort to survive the hit. With one powerful quote, Rachel admits that it is foolish to spare Leekie's life, but he raised her. "Nurture prevails," she says, which is basically the central discovery of this entire series.
Of course, it'd be far too easy if Leekie got away. Donnie, now armed with knowledge and literally armed with a handgun, tracks Leekie down for retribution. Poor Donnie, in another moment of pure idiocy, decides to punctuate his statement of resignation from the program with a smack to his steering wheel...and with it an accidental trigger-pull of that handgun, angled so it shoots Leekie directly in the head.
With episode seven down and only three more to go before the end of the season, I'm glad these loose ends are beginning to knot up. It's good to see that many of the secrets from earlier this season are already being wrapped up. Cosima's now aware of the stem cells' origins and has seemingly isolated Delphine thanks to her secretive nature, Donnie's cognizant of the clone experiments, and Rachel understands her mentor's involvement in her mother's murder.
With these secrets now common knowledge, we can now move on to the bigger picture questions. Will Rachel join Sarah Manning in her anti-Dyad fight? Will Helena's dream of a family come to pass, no matter how unsettling the Prolethean lifestyle that accompanies it? What will become of Kira if Sarah gets her too close to the Dyad, now that Leekie's gone? It's obvious that the line of power at the Dyad stretches well beyond Rachel and Leekie and probably even beyond the new boss, Marian, but I'm pretty positive Paul would dive in and snatch up the miracle child of Sarah Manning at any chance he could.
I'm hoping to see a change of heart from Rachel. It'd be good for Sarah to have a powerful ally in her corner, no matter how strained the relationship is. At this point, I'm willing to replace Rachel with Marian in a battle with the Proletheans for this season's Best Villain Award.
