MIRIAM: The Doctor and the Daleks, the Daleks and the Doctor. Have you never thought they were both really the same thing?

EVELYN: What are you talking about?

MIRIAM: One invades, destroys, exterminates. The ultimate bogey-man. Good night, sleep tight, make sure the Daleks don't bite. The other, our fearless Champion, the perfect hero who will protect us from harm.
