Dollhouse S01E10

Spy in the House of Love

While DeWitt is away on business, Topher discovers evidence of a spy in the Dollhouse, and four Actives are dispatched to deal with the problem. "Mellie" is sent to pacify Paul Ballard, but goes temporarily catatonic to deliver another warning from that spy. Sierra goes undercover at the National Security Agency, attempting to raid their databases for the spy's identity. Victor is dispatched on another "Lonely Hearts" gig; the recipient is revealed to be DeWitt. Finally, Echo volunteers to undergo imprinting to help with the investigation; after Topher turns her into a counter-intelligence agent, she helps Lawrence Dominic, the head of security, interview employees. She discovers the mole is Dominic himself, planted by the NSA to keep the Dollhouse (and its dangerous technology) from becoming common knowledge, particularly by staving off Paul Ballard. Dominic's personality is downloaded by Topher, and his body sent to "The Attic," to be employed whenever the NSA needs pacifying.
