Doctor: 'How long you going to stay with me?'Rose: 'Forever.'
'Army of Ghosts' and 'Doomsday' will forever be remembered as Rose's swansong. It was the end of a two year adventure which saw her transformed from inexperienced shop girl into seasoned time traveller. Rose swearing to stay with the Doctor forever, shows us just how strong her commitment to that new life is. She's in it for the long haul. Her and the Doctor are as 'together' as they're ever likely to be—but that's all about to change. Rose's monologue at the start of the episode prepares us for the worst. And despite the Doctor's reassurances to the contrary, it appears that the Beast was right, after all. Rose is going to die.
