"What they're doing for fun," Ino said slowly, getting up and meeting his eyes. "My family makes a living out of, back home. Taking over peoples bodies, using them against each other, pretending to be them and not just be 'someone else in their body'. We know about the chemical differences between male and female brains, old and young, how diets and levels of activity affect the way you think. In taking over someone else's body with your mind you're entering hostile territory--it's not a game. It's not safe. It's not a lark."

"You're in someone else's body," she said. "You're both you, and not you because that body doesn't understand your mind, and your mind doesn't understand that body. It's not a simple thing, a flick of a switch, or anything like that. All it takes is one hormone being at a different level from what you're used to in your own body--and then it's dangerous. The chemicals in your brain alter the way you think, and everybody is different--because we're all different--and that's not something that should be played with."
