Sarah visits the archives to learn more about Ethan, and with the aid of Art and Felix investigating the files from Maggie's locker, learns that he changed his name to Andrew Peckham. Helena finds a bar and makes a connection with local man Jesse, but she is later arrested for fighting with some drunks. Mark and Gracie later invite Helena back to Henrik's ranch to allow herself to be inseminated with her own fertilized eggs. Scott Smith, a fellow student of Cosima's, joins her and Delphine at Dyad, and learns that the stem cells Cosima was given belong to Kira. At rehab, Alison befriends Vic, who is later revealed to be an informant for Angela to get dirt on Alison. Sarah arrives at a house only to find Mrs. S, whose old contacts have protected Ethan for years.
