The Doctor

"They are so tired. So godsdamned exhausted and weary and just wondering whether or not it’s worth it.

But they don’t necessarily want to show it. They’ve got people around them, and sometimes it helps, and they run these brilliant streaks of manic joy and madness through life, all bluster and bravado and excitement and sometimes you’d never realize how much of it is an act until, bam, that switch flips. That switch flips, and the sadness and the anger and the depression and the self-loathing kick in, and you see what’s behind the mask. What they’re fighting, what they’re trying to hold off, every day.

Ten had his moments like that, too, but his happiness, it was more genuine. It was more joy, less escape. When Ten was alone, he was lonely. When Nine and Eleven are alone, they’re stuck with themselves, and that’s even worse.

Yeah. So I think that’s why I love them so much."
