She had pointed it at a goth girl standing with her friends loitering and, as she watched, the girl began to change, growing older, her clothes shifting.
Within seconds, the girl had become a woman in her thirties, wearing a yellow sundress and carrying a purse. She looked like any of a dozen other women roaming around. She passed the other Goths, as if she didn't even know them, going about her business.
She tried again, shooting the other two Goths, who also turned into mature women, joining their friend again. She looked on, approvingly. Three troublemakers turned into fine upstanding members of society. She wondered how that could be, but it clearly did work.
This required more experimentation. Would it only work on girls like that? She looked around for someone else to try it on.
