DOCTOR: It's happening over and over again. Every time I landed there. 1999. 1066. 2005. The Earth is dying… so many times.

DOCTOR: Every world that I ever stood upon… all dead. Venus. Telos. Karn. The Ood Sphere. And Skaro.

MEL: The Daleks are dead?

DOCTOR: Everything is dead.

MEL: But there's so many places you haven't been. They must be safe.

DOCTOR: I've travelled so far. Everything caught in that pattern is dying. The whole of Time and Space. I did this.
