The sense of paranoia grows as Sarah and her clone sisters realise that even their nearest and dearest cannot be trusted.
Who watches the watchers?
Paul again surprises Sarah at home. After sleeping together, she wakes from a nightmare in which surgeons are operating on her. She realises it was real when she coughs up an electrode.
She and Alison become suspicious that the men in their lives are monitoring them, leading her to discover that Paul is ex-military.
Alison’s search reveals a padlocked metal box in the garage. When she confronts Donnie, he runs off with it but she later finds it contains a planted stash of porn. Donnie burns the original contents.
Sarah goes to Paul’s office to check on him and plant a bug, but he notices she is missing a scar Beth had on her neck. However, when he reports in to a man named Olivier he doesn’t mention this. He confronts Sarah and she claims to be Beth’s twin.
Alison goes to buy a spy camera but encounters Vic – now missing the end of a finger – who mistakes her for Sarah. Sarah has to pay him off out of Alison’s emergency fund.
Cosima continues to test the blood samples from Katja’s briefcase and suggests their monitors may be part of a ‘double-blind’, being kept in the dark about the experiment to avoid skewing results. She meets a French student, Delphine, and strikes an immediate friendship.
Conspiracy and claustrophobia
The conspiracy thriller at the heart of Orphan Black jumps to the fore as the focus shifts from the girls to their partners (Paul and Donnie), ex-partners (Vic) and potential partners (Delphine), and we start to peel back the layers of the mystery as to why the clones exist in the first place.
Sarah and Alison in particular feel the world closing in around them as they discover they are being watched and cannot trust loved ones. The girls are drawn closer together as they realise they have no one but each other.
Vic now knows Sarah is alive – an unwanted complication. Sarah-as-Beth is now exposed, to Paul at least. And the nature of Alison’s relationship with Donnie is changed forever as she starts to spy on him.
Once again, Tatiana Maslany’s versatility shines through when Paul surprises her in the shower. It takes a few seconds for Sarah to regain her composure and transition from her natural accent – she calls Paul an ‘arsehole’, a distinctly British insult – into Beth’s voice. Subtle but effective.
This week’s big questions
Paul was Beth’s monitor and it is implied that Donnie is Alison’s. Does that mean Sarah is also being watched? And is Cosima’s connection with Delphine more than a chance encounter?
In addition to Alison, Paul confirms that Beth couldn’t have children either. Why is Sarah different? Paul says he couldn’t leave Beth: ‘You think I had no choice?’ What hold does the mysterious Olivier have over him?
