Key Dialogue

"SEA DEVIL: This is our planet. My people ruled the Earth when man was only an ape."
"DOCTOR: The depths of the sea and those areas on Earth where man cannot live can be yours."
"SEA DEVIL: And man would agree to that?"
"DOCTOR: There's a chance. Wouldn't it be better to try for a peace, than to launch yourself into a war that you cannot possibly win?"
"SEA DEVIL: I will consider what you have said."
"MASTER: No! The Doctor is your deadly enemy! He must be destroyed!"
