01E11 - Briar Rose

Echo is imprinted with the mind of a teacher to help out an emotionally disturbed 11-year-old girl deal with her traumatic past, which seems to parallel Echo's. Meanwhile, Ballard escalates his quest to find the Dollhouse which leads him to a shut-in, named Stephen Kepler, whom was the architect of the L.A. branch building of the Dollhouse who reluctantly gives him information about its location. When an unidentified dead body is found in Arizona, Sierra is imprinted as an FBI forensic specialist to investigate when the MO has the likings of the mysterious Alpha. Back in the deep bowels of the Dollhouse, Adelle goes to "the Attic" where she has the comatose Dominic imprinted into Victor to interrogate him for information about who is behind Ballard's quest to find the Dollhouse. When Ballard finally discovers the location of the Dollhouse and breaks in to look for Echo, he is caught by Boyd who takes him to Adelle for questioning just when Sierra phones from Arizon to inform them that the corpse of the unknown man thought to be murdered by Alpha is that of a "Stephen Kepler". Ballard's helper is actually Alpha... who reveals himself by attacking Victor and Dr. Saunders. Alpha/Kepler imprints Echo with a memory that makes her recognize him as her former lover.
