Amy looking at the Doctor
“That’s what interests me about The Doctor because, actually, look at the blood on the man’s hands. 900 years, countless very selfish choices, and he’s literally blown planets up. His own race, you know, that’s all on his hands. Which is why I think he has to make silly jokes and wear a fez. Because if he didn’t, he’d hang himself.” - Matt Smith
