- Dr. Who: As I said my dear, it's fortunate for all of us that everything is dead.
- Barbara Wright: Yes.
- Susan Foreman: [seeing the giant cat which is very much still alive] Grandfather!
- Ian Chesterton: Barbara! He's standing at the sink. I can see him standing at the sink. He's turned the tap on!
- Ian Chesterton: [separated from the Doctor and Susan, Ian and Barbara find themselves in a laboratory] Look at those enormous test tubes!
- Forester: [trying to explain Farrow's dead body] He pulled it out of his pocket and told me he was stealing the formula. I struggled with him. The gun must have been turned to his body. It went off.
- Smithers: [after a cursory examination of the corpse] I wouldn't try telling that story to the police, if I were you.
