DOCTOR: It would seem the storm has animated your Gangers.

CLEAVES: They've ransacked everything.

DOCTOR: Not ransacked, searched.

CLEAVES: Through our stuff!

DOCTOR: Their stuff.

JIMMY: Searching for what?

DOCTOR: Confirmation. They need to know their memories are real.

BUZZER: Oh, so they've got flaming memories now.

DOCTOR: They feel compelled to connect to their lives.

CLEAVES: Their stolen lives.

DOCTOR: No, bequeathed. You gave them this. You poured in your personalities, emotions, traits, memories, secrets, everything. You gave them your lives. Human lives are amazing. Are you surprised they walked off with them?
