I showed a girl from my world a simple, harmless vision of her past, because there were things she needed to know, and I was called in for a lecture and had a part of my power stripped. This was after she'd assaulted me and threatened my life, incidentally, which was deemed unworthy of investigation.
[Never mind that he told Acumen about the assault, not the DF. If they were such a good police force, they would've known about it anyway, right? /logic]
