|Roses are red|

Doctor Who AU - He Drove Himself Crazy
The Doctor decided to make contact with Rose Tyler at Bad Wolf Bay for one last time, thinking that she and his metacrisis clone were happy. Instead, he was faced with a mourning Rose who told him that his half-human counterpart had gone mad and died, leaving her all alone.
This is just terribly heartbreaking.
