Quote from : Doctor Who: Winner Takes All Book

He loved books like that, and telly, and films. He loved stuff where there was a Chosen One, a special person, a hero, and he loved to imagine that one day things like that would happen to him. But there was one thing he'd noticed, and that was that however much the hero seemed to risk his life, all the way through there would be other people risking their lives too, happy to give up their lives so the Chosen One, the hero, could live to fight another day, or do something clever, and everyone accepted that that was just as it should be. Often the hero didn't even know their names. He certainly rarely gave them a second thought, after the first brief regret of the loss.
