Episode list

Once again, the TARDIS displays its preference for the grimy, the odious and the dangerous - and, finding himself lost and alone in the dark heart of a gigantic spacecraft, the Doctor has no way of knowing that a cosmic catastrophe is waiting to happen.

No one could ever know. We had to erase the past. Change everything. Start again. But even though it's been centuries now... In our hearts, none of us feels truly... Safe. I think, even if our people were to survive until the end of time itself, we would still fear... The return of the Daleks.
