May as well try to explain how magic itself worked. She could explain the mechanics, sure, but even she wasn't sure why it worked the way it did.
"Usually someone will come up and sit in front of me, and I'll talk to them," she began. "And then, there's...something in my brain, a switch gets flipped, I don't know, but my voice...changes. They pay attention like I'm the most important person in the room. Then I'll take their hand, or touch their shoulder, and I tell them what I want them to do, and when I want them to do it. Snap my fingers, break the trance, say the word at some point during the night. Once they do it, my hold's gone, which works out for the act."
