Okay, so, Cosima’s safety is important enough to Delphine for Leekie to use it as incentive? More important than the others? What’s the Leekie-approved reason for that? Why’s Cosima so important to Delphine, beyond anything romantic? And speaking of their dynamic, Cosima’s the only clone being brought anywhere near the inner Neolution workings deliberately. Even before it was discovered that Sarah wasn’t Beth, Delphine had met Cosima and invited her to the Leekie seminar. I wonder if they actually mean to use Cosima’s intelligence and scientific curiosity to experiment on herself?

That last part is especially intriguing. Delphine makes the decision to split with Leekie, to lie to him, to place herself in a lot of potential danger, not for Cosima, but Sarah Manning’s daughter. The same child who is actually near the center of the show, being so dear to Sarah, Mrs. S, Felix, and now Helena. And who we last saw being sped to a hospital in an ambulance.
