Cosima suspects that Delphine is her monitor and is confident she can control their relationship and any fallout that may occur. Helena is recovering from her wounds but tells Sarah she wants the names of the other clones. The police meanwhile have determined that the victim from the gravel pit and the killer in the bathroom have identical DNA. They assume it must be the same person or that the samples were tampered with. Sarah learns about some of her past from Mrs. S. Olivier receives orders to bring Beth in when medical tests reveal an impostor.
