- Li H'sen Chang: I will now ask my eager volunteer kindly to step into the Cabinet of Death.
- [the Doctor enters the cabinet. Doors are shut. Chang and his assistant turn the cabinet around to show audience that the back is solid. While the front doors face upstage, the Doctor slips out and walks off into the wings, in full view of all. Chang, puzzled by the audience's laughter, swings the cabinet round and opens the doors. It's empty, but he takes it in stride]
- Li H'sen Chang: The bird has flown. One of us is yellow.
- Casey: But you don't do anything, Mr. Jago.
- Henry Gordon Jago: I... I announce the acts, I count the tickets, I smile at people - you no idea the strain it puts on a fellow.
- Henry Gordon Jago: There he is, in the box, see?
- Casey: Don't look like a detective to me
- Henry Gordon Jago: Well, he's not going to wear a brown derby and boots now, is he, secret investigator like him, a man of a thousand faces?
- Casey: Who's the girl?
- Henry Gordon Jago: Window dressing. Part of his disguise.
- Doctor Who: When the moment comes, Mr. Jago, you and I can face our destiny shoulder to shoulder.
- Henry Gordon Jago: [glum] Oh, corks.
- Li H'sen Chang: Next trick very simple. Will someone take cards, please. You, sir. Catchy.
- [Chang tosses the deck to the Doctor in the balcony]
- Li H'sen Chang: Now, sir, please to assist humble Chang by selecting any card. Ace of Diamonds. Please to hold card in air so everyone see. Now, sir, please to return card to pack, any place. Honorable gentleman please to hold pack of playing cards between finger and thumb.
- [Doctor holds out the deck]
- Li H'sen Chang: Chang will now shoot magic bullet through Ace of Diamonds without hitting other card. Please to keep very still.
- Leela: Doctor!
- [Doctor defiantly holds cards closer to his face. Audience gasps]
- Li H'sen Chang: Please to keep very quiet. Chang shoot fifty peasants learning this trick.
- Doctor Who: If his DNA helyx is split open, the more cells he absorbs into himself; the more deformed he becomes.
- Leela: You mean he's like a water bag with a hole in the bottom and the hole is getting bigger?
- Doctor Who: Yes.
