Episode Recap

Although she doesn’t trust him, Sarah knows that Ferdinand now is her strongest lead in getting the bot removed in that he knows the one person who can remove it: Susan Duncan. In return, Ferdinand also wants access to Susan as he knows that she has Rachel, who he wants to save. MK is the person who has the skill set to locate Susan. As Sarah will not divulge MK as her source to him and as Sarah does not want to tell MK that Ferdinand is the person that has been helping her, Sarah needs to act as the go-between. Either finding out the identity of the other could have major repercussions, especially concerning MK’s past. While out for coffee, Alison is accosted by Trina believing her to be Beth. Trina’s accusations lead to Alison needing to follow another path to a fertility clinic to find the link back to Neolutionists. As she knows that one of her sisters has been to the clinic, Alison needs to enlist the help of others to infiltrate the clinic. This includes Felix, who has reemerged in the sisters’ lives as he finds out about Sarah’s current predicament with the bot. Cosima and Scott are able to remove the bot from Aldous’ face, his bot which is encased in a tumor. They have to find out the nature of the tumor to hopefully find out the purpose of the bot. Donnie has a heart-to-heart with Helena about how difficult the talk of a sister having a baby is to Alison. As such, Helena makes a decision of her own. And Rachel sees the signs that Charlotte, her only trusted conduit to the outside world, suffers the genetic defect that has killed many of the clones. Rachel also knows that Susan would see that Charlotte, in being the youngest ever to develop the symptoms, is worth more to the project dead than alive.
