They’re on the beach of Bad Wolf Bay, and this can’t be happening; not again, not after all she went through to get back to her own universe, to return to her Doctor’s side!
Rose wants to tell the Doctor ‘No’, that she won’t go back to the alternate universe, that she belongs with him, in the TARDIS, travelling through space and time forever. She wants to beg him, ‘Don’t leave me!’ Did he ever truly care about her the way she does about him? If he loves her how can he reject her like this?
It hurts so much.
