(on what will happen to "Doctor Who" when he takes over")
Steven: You change everything, all the time. Even that element of the show has changed radically over the past four years... You don't worry about doing things radically, in an a new way... [You] do what tells the story...[Originally] we knew Rose much better than the Doctor, and now we know the Doctor better than we know Rose. And now we see Rose from the Doctor's point of view, instead of seeing the Doctor from Rose's point of view. You have to stay alive and stay lively, and Doctor Who is about change. Change is part of Doctor Who's formula. It must change.
