"I’ve seen lots of people die: All those aboard the R101, and then the people on The Vanguard, all those histories we overwrote; Lives never even lived. You never get used to it. The thought of those we’ve met and seen die still scrambles my insides, I remember their faces and sometimes their names. But I have to try to remember. Then there are the faces that come back unbidden in the middle of the night, Vinx and Gleen and the smallest Antle who didn’t yet have a name. The kindness they’d shown us despite all they’d lost; Their gratitude and grief, they’re the ones who haunt me. I made The Doctor go to see them, and it’s good that we did, but now I understand."

Charley my glorious goat, man.
