02E10 - By Means Which Have Never Yet Been Tried

Now that she has Kira and her harvested bone marrow, Rachel is holding all the cards. She replaces Delphine with a Dr. Nealon as the facility and thus Cosima's chief physician, not even letting Delphine say goodbye before she is escorted out of the facility. As such, Rachel can use Cosima and Kira as a bargaining chip, which works as Sarah feels she has no other option but to surrender herself to Dyad, although Sarah still stays as defiant as ever under the circumstances. However, some will do anything, even risk their own life, to stop whatever Rachel's grand plan. And on the outside, Mrs. S and Felix, with a little help, believe they may have an inside track on what's happening within the Dyad facility. Sarah ultimately has to decide whether to trust that insider and the promise made. And after the fire at the Johanssen farm, those involved are able to escape they hope to a better life. Helena hopes to reunite with Sarah and Kira, but what happens may be beyond her comprehension. And Mark and Gracie want to get married in peace, but the next phase of the Leda project may factor into what happens to them.
