AMY: Where are we?
DOCTOR: We're in trouble.
RORY: What is that?
DOCTOR: A star. A cold star. (runs to the doors and opens it, letting in a blinding light) That's why we're freezing. It's not a malfunction. We're drifting towards a cold sun. That's our danger for this version of reality. (closes door and looks at the larger monitor on the wall)
AMY: This must be the dream. There is no such thing as a cold star. Stars burn.
DOCTOR: So's this one. It's just burning cold.
RORY: Is that possible?
DOCTOR: I can't know everything. Why does everybody expect me to, always? (heads to console area and sits dejectedly)
