Doctor and Rose *season 4 finale spoilers*

Concerning Doctor Who: why oh why must the best things always be painful? Why can't they just be happy? I guess it's because the bitter in the bittersweet makes the sweet sweeter. The Doctor is so sad that I can hardly stand it. And Rose is so happy in her life now, but she's only with the doctor in a way that's not ideal (with the Doctor's semi-human double). She will have to settle for the piece of the doctor that she does have. It's a pretty big piece, but still... Tragedy.
