You find yourself drawn to a small apartment above a garage. You fly in through a crack in the window.
You are horrified at the filth. Week old pizza crusts, dirty, filthy clothes and sheets with encrusted semen, and a powerful stink. In the middle, sitting on the bed weeping, is the dirtiest man you have ever seen.
He looks at you. "Please, you've got to help me, I can't hold myself back anymore and I'm going to--if you don't help me, please."
"You're going to do what?"
"I'm going to kill someone. It's the only way to get these voices to shut up. They want me to kill a little girl and I've kept from doing it but I can't any more unless you help."
A vision of the future flashes into your mind. A small body, not breathing. Bereaved parents with the joy sucked out of their lives. The man talking to you, stabbed to death in a prison shower. Suddenly you realize that you have a serious job, it's not a game.
"OK, I think there's something I can do. Are you ready?"
"Please, anything."
You wave your wand, and the filthy man changes. Flesh vanishes from his waist, to reappear on chest and hips. The head shrinks slightly. Most importantly, the chemicals of the brain change, and along with them the personality.
A fat woman sits on the bed, her face transfigured with joy. "They're gone." she says. "They're gone. The voices. I don't have to hurt anyone. Thank you, thank you."
"Life isn't going to be easy." you say.
"It doesn't matter, it doesn't matter." the woman repeats. She smiles. "Maybe I'll start by cleaning this place up."
