Next Time on Doctor Who…

Below a bright white sky a blue humanoid dressed royally stands before a crowd of similarly shaded people on golden grass. "I… I have grave news, indeed. Just when we discovered that we were not alone in the universe we have found out that we may be in our last days…"

The doors to a lift fly open.

"…They are here at our door and they threaten everything that we know..."

Dalek Caan stands by Abel in a room, "The-Dal-eks-on-ly-know-one-way-of-life. Ex-ter-min-ate."

"…There is something that we should have told you centuries ago…"

The Doctor regards someone with a wealth of regret. "What have I done to you?"

"…The Time Lord myth is true…"

The Doctor stares out at an object from the TARDIS completely unbelieving and terrified.

"…and one of them left behind something truly special eons ago…"

The Doctor commands to Martha and someone else, "Run!"

"…If unleashed it could destroy our planet and whatever else lives amongst the cosmos…"

"This… this can't be here! No, there's no way! Everything is gone. This is impossible!"

"…A ship hovers above our atmosphere and they want this weapon. If they succeed we all are doomed…"

A shadow of a large object above the skies passes over the Doctor chillingly…

The Doctor tells someone about a future event. "You… that is you, Rose Tyler are going to die..."

Series 4 will continue with "Caan and Abel" next week!
