“Creatures from another world, only statues when you see them. Lonely Assassins, that's what they used to be called. No one quite knows where they came from, but they're as old as the Universe, or very nearly. And they have survived this long because they have the most perfect defence system ever evolved. They are Quantum Locked. They don't exist when they are being observed. The moment they are seen by any other living creature they freeze into rock. No choice, it's a fact of their biology. In the sight of any living thing, they literally turn into stone. And you can't kill a stone. Of course, a stone can't kill you either, but then you turn your head away. Then you blink. Then, oh yes, it can. That's why they cover their eyes. They're not weeping, they can't risk looking at each other. Their greatest asset is their greatest curse. They can never be seen. Loneliest creatures in the Universe. And I'm sorry. I am very, very sorry. It's up to you now. Don't blink. Don't even blink. Blink and you're dead. They are fast. Faster than you can believe. Don't turn your back, don't look away, and DON'T blink. Good luck.”

“Amy: So. Are you proposing to someone? The Doctor: Sorry? Amy: I found this in your pocket. The Doctor: No. No no. That's a memory. Friend of mine. Someone I lost. Would you... mind. Amy: It's weird. I feel... I dunno, something. The Doctor: People fall out of the world sometimes but they always leave traces. Little things we can't quite account for. Faces in photographs. Luggage. Half-eaten meals. Rings. Nothing is ever forgotten, not completely. And if something can be remembered it can come back.”

“There ya go, end of the universe, butterfingers.”

“You take this cold, remarkable, difficult, dangerous, borderline psychopath man, and you wonder what might have happened to him had he not met his best friend, a friend that no one would have put him with – this solid, dependable, brave, big-hearted war hero. I think people fall in love, not with Sherlock Holmes or with Dr. Watson, but with their friendship. I think it is the most famous friendship in fiction, without a doubt.”
― Steven Moffat, Sherlock Holmes on Screen
