Sarah, ever the protector, sets her focus on finding Kira and keeping her safe. Her first priority is ensuring that Kira isn't targeted by those who helped Rachel execute her plan for the Dyad Institute. Her love for her daughter is evident, as she sacrifices her own chance to get away to ensure her daughter is always safe. Kira is one of the most important parts of Sarah's life, and she will not let anyone hurt her.

Alison is dealing with the news that she has a doppelganger. She is overwhelmed by the thought that her life is not her own, that she may not be who she has always believed herself to be. This self-discovery leads her to question her own sanity, and she is forced to take a break from her regular life in order to come to grips with her newfound identity. Alison has always been a force to be reckoned with, but the realization that she has never been "normal" could have a profound impact on her going forward.

Cosima is struggling with both her own health and the realization that she may have been betrayed by Delphine. Cosima learns that the Dyad Institute was keeping tabs on her and may have played a role in her diagnosis of the disease. Delphine's loyalties are called into question, and the trust between Delphine and Cosima is tested. Cosima is going through a lot, but despite it all, she manages to keep her scientific mind focused on solving the problem at hand.

Helena is recovering from the gunshot wound she received from Mark. She is in a fragile state and is struggling to come to terms with the fact that she killed her own sister.
