HANDBOT: Apalapucia is under planet-wide quarantine. This is a kindness facility for those infected with Chen Seven.

(The Doctor covers his mouth and nose with his coat lapel.)

DOCTOR: What?

RORY: Chen Seven, hmm?

DOCTOR: The one day plague.

RORY: What, you get it for a day?

DOCTOR: No, you get it, and you die in a day.

RORY: This is your fault.

DOCTOR: I’m so sorry, but, Rory--

RORY: No, this is your fault! You should look in a history book once in a while, see if there’s an outbreak of plague or not!

DOCTOR: That is not how I travel.

RORY: Then I do not want to travel with you!

DOCTOR: It’s your choice.

RORY: This isn’t fair. You’re turning me into you.
