POLLY: Then you don't mind if we all die.

KRAIL: Why should we mind?

DOCTOR: Why? Why?!

POLLY: Because millions and millions of people are going to suffer and die horribly!

KRAIL: We shall not be affected.

POLLY: Don't you think of anything except yourselves?

KRAIL: We are equipped to survive. We are only interested in survival. Anything else is of no importance. Your deaths will not affect us.
