“Heroes are important. Heroes tell us who we want to be but when they made this particular hero they didn’t give him a gun, they gave him a screwdriver to fix things. They didn’t give him a tank or a warship or an X-Wing, they gave him a call box from which you can call for help and they didn’t give him a superpower or a heat-ray, they gave him an extra heart. And that’s extraordinary. There will never come a time when we don’t need a hero like the doctor.”

The Doctor: Because every time you see them happy you remember how sad they're going to be. And it breaks your heart. Because what's the point in them being happy now if they're going to be sad later. The answer is, of course, because they are going to be sad later.
~ The Doctor, the Widow, and the Wardrobe”
