(The Doctor believes Rose has been killed by the Dalek)
The Doctor: I could have killed that Dalek in its cell. But you stopped me.
Henry Van Statten: It was the prize of my collection!
The Doctor: Your collection? Well, was it worth it? Worth all those men's deaths? Worth Rose? Let me tell you something, Van Statten, mankind goes into space to explore, to be part of something greater.
Henry Van Statten: Exactly! I wanted to touch the stars!
The Doctor: You just want to drag the stars down and stick them underground beneath tons of sand and dirt and label them. You're about as far from the stars as you can get. And you took her down with you.
