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.

PEX: Are these old ladies annoying you?

MEL: No!

PEX: Are you annoying these old ladies?

TILDA + TABBY: No, she isn't.

PEX: Oh.

DOCTOR: You know, you really are very stupid for such clever people. If I were you I'd find that door and discover what's behind it. Because until you do, we're all at risk, You, Me, Mel, everybody. Are these antiques dotted around all over the building? It really is a splendid piece of auditoryarchitectatonicalmetrasyncocity.

FIRE ESCAPE: It works!

DOCTOR: I'm sure.

DOCTOR: Do you usually do what I usually do in these circumstances?

DEPUTY: What's that?

DOCTOR: Run!

DOCTOR: At least tell us who you are.

BIN LINER: We're the Kangs.

FIRE ESCAPE: Red Kangs. Red Kangs are best. (to Kangs) Who's best?

RED KANGS: (chanting) Red Kangs! Red Kangs! Red Kangs are best!

BIN LINER: (threatens the Doctor with a crossbow) So, who's best?

DOCTOR: The Red Kangs, I gather.

(shortly after)

BIN LINER: (to Mel) Are you a Blue Kang?

MEL: No! No, I'm not a Kang. I'm Mel. I don't know what the Kangs are.

FIRE ESCAPE: We're the Kangs! Red Kangs.

DOCTOR: (chuckling nervously) Who are, of course, the best.
