The Tenth Planet

KRAIL: You must come and live with us.

POLLY: But we cannot live with you. You're, you're different. You've got no feelings.

KRAIL: Feelings? I do not understand that word.

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.

POLLY: Like you?

KRAIL: We have freedom from disease, protection against heat and cold, true mastery. Do you prefer to die in misery?
