DOCTOR: Greetings.
CARETAKER: I am the Chief Caretaker.
DOCTOR: And I am-
CARETAKER: No need to tell me. I know who you are. We have been waiting for this momentous visit for so many years. You are the man who brought Paradise Towers to life. The visionary who dreamed up its pools and lifts and squares. And now you have returned to your creation. You will make all those dilapidated lifts and rise and fall as they've never done before. All signs of wallscrawl will disappear from the corridors of Paradise Towers. The floors will gleam and the windows will shine, and will be made as new. Fellow Caretakers, do you know who this is? This is the Great Architect returned to Paradise Towers. Bid him welcome. All Hail the Great Architect, all hail.
CARETAKERS: All hail the Great Architect.
DEPUTY: What shall we do with him now then, Chief?
CARETAKER: Kill him.
