Cosima calls Sarah to tell her about the tags. Sarah says she’s about to meet with Leekie. Cosima asks her to at least listen to him.
Leekie says he just oversees data collection. There are other parts of the project that he doesn’t know. But he wants to make a deal. If Sarah can give him Helena – who he says will be treated and deprogrammed – he’ll give her all the answers she wants. He explains that Tomas is a religious extremist, a Proleathean.
