Meet Jane Doe

As Paul helps Echo regain control over all the personalities in her head, Topher perfects a way to turn anyone into a Doll.

Tropes present in this episode:

Character Development: During the time skip, Echo's doll personality has evolved into a complete person, different from Caroline Farell.
Foregone Conclusion: Due to Epitaph One, we already know that the technology Harding has Topher working on will contribute to the Dollhouse-pocalypse. Topher realizes that Rossum has each Dollhouse working on a component of a universal, wireless imprinting device.
Interplay of Sex and Violence: Ballard and Echo's sparring session gets very sexually charged.
Long Game: Echo has spent three months preparing to help the woman she got arrested before the time skip escape from prison.
Nice Job Fixing It, Villain: Bennett giving Echo a memory with Caroline in it triggered Echo's ability to access her latent imprints at will.
Power at a Price: Echo's increased ability to channel her imprints comes at the expense of increasingly debilitating headaches.
Running Gag: Once again, the Active designated Kilo is a test subject for one of Topher's inventions.
Shout-Out: Topher remarks that Bennett went all Cylon on him.
Time Skip: This episode skips three months, after which Adelle has been ousted as the head of the L.A. Dollhouse.
