YMMV / Dollhouse S 01 E 01

• Complete Monster: The unnamed, pedophilic kidnapper is a Serial Rapist and killer of little girls. When twelve-year-old Davina Crestejo is abducted by him and his cohorts, the doll, Echo, is implanted with the artificially constructed personality of a hostage negotiator named Eleanor Penn, and sent by the Dollhouse to negotiate Davina's release. The personality of Ms. Penn was constructed partially from the memories of a little girl who was kidnapped as a child herself. When the time comes for the kidnappers to collect the ransom, however, Ms. Penn has a nervous breakdown upon seeing the face of one of the kidnappers and recognizing him as the same man who kidnapped her as a child. She then reveals this kidnapper's modus operandi. Kidnapping little girls, he ransoms them to their parents, then, after the money arrives, murders his partners and keeps the girls as his Sex Slaves, killing them when they grow too old for his tastes. When Echo informs his fellow kidnappers about what their partner's planning for Davina, they are so disgusted that they immediately try to kill him before allowing Echo to leave with Davina.
