Dollhouse - Season 2 Episode 10

We finally enter the mysterious Attic – the secret vault where the Dollhouse keeps damaged actives and problematic employees unconscious and in a perpetual state of terror. Adelle has had Echo sent there, along with Victor and Sierra, on the grounds that her multiple imprints and their growing self-awareness are making the three a danger to Rossum. In the dream-world of the Attic, Echo and her friends forced to face their worst nightmares repeatedly, and their only ally is former Dollhouse security head Laurence Dominic, sent there earlier when he was discovered to be a spy for the NSA. Together they must confront a mysterious predator bent on killing the Attic's prisoners, as they try to uncover the mystery of the Attic's true nature and purpose. Meanwhile, Adelle forces Topher to find a way to restore Ballard's damaged brain in order to revive him – at a terrible cost.
