Complete story — includes the ending
Delphine meets the Leda clone Krystal and afterward informs Nealon that Krystal has no idea about clones. David Benchman informs Coady that they have infiltrated Dyad. Rachel will only decode the symbols in Ethan's The Island of Doctor Moreau book if Sarah and Scott help her escape to Taiwan with a new life using Krystal's identity. Sarah and Felix go to Krystal's place of work, a beauty salon, where Felix poses as a customer to steal her wallet. Felix discovers that although Krystal is not a self-aware clone, she began investigating her attempted kidnapping by Rudy and Seth. Rudy shows up at Scott's apartment and steals Ethan's book by threatening Scott's cat. Delphine suspects that Rachel or Shay have been spying for Castor people. Delphine fires Scott for not reporting the book earlier; Scott previously made a copy of the book. Cosima refuses to accept more treatment using Kira's stem cells, and she resigns from Dyad. Rachel begins translating but Nealon busts in, taking her and the book before smuggling Rachel away for prosthetic eye surgery using Krystal's identity. The Neolutionists have held the real Krystal in a medically-induced coma in Rachel's place at Dyad, to fool Delphine and the other clones. From what they saw translated, Mrs. S, Felix, and Sarah believe the Castor original is in London.
