Steven Moffat Quote

When you run with the Doctor, it feels like it'll never end. But however hard you try you can't run forever. Everybody knows that everybody dies and nobody knows it like the Doctor. But I do think that all the skies of all the worlds might just turn dark if he ever, for one moment, accepts it.

Lines written for River Song, in Forest of the Dead [4.9] (7 June 2008)
