Krail: You must come and live with us.
Polly Wright: But we cannot live with you! You're different. You've got no feelings.
Krail: Feelings? I do not understand that word.
The Doctor: Emotions. Love. Pride. Hate. Fear. Have you no emotions, sir?
Krail: Come to Mondas and you will have no need of emotions. You will become like us.
[Mondas is draining Earth of its energy]
Cyberman: You must come and live with us.
Polly: But we cannot live with you, you're... you're different, you've got no feelings.
Cyberman: Feelings? I do not understand that word.
The Doctor: Emotions! Love, pride, hate, fear! Have you no emotions, sir?
Cyberman: Come to Mondas and you will have no need of emotions. You will become like us.
Polly: Like you?
Cyberman: We have freedom from disease, protection against heat and cold, true mastery. Do you prefer to die in misery?
Polly: But look, surely I... it's possible for us not to lose Earth's energy?
Cyberman: It is inevitable.
Polly: Then you don't mind if we all die.
Cyberman: Why should we mind?
The Doctor: [outraged] WHY? WHY?
Polly: Because millions and millions of people are going to suffer and die horribly!
Cyberman: We shall not be affected.
Polly: Don't you think of anything except yourselves?
Cyberman: We are equipped to survive. We are only interested in survival. Anything else is of no importance. Your deaths will not affect us.
Polly: But I can't make you understand, you're condemning us all to die! Have you no heart?
Cyberman: No, that is one of the weaknesses that we have removed.
