Herself, in a misfire.

A few emotions flit across Vanessa's face, very quickly. Giddy anticipation, as she raised her wand up to her target. A wince, in reaction to the still unfamiliar sensation of using the wand. This was followed by confusion, as the light did not fly into the coffee shop, like she meant it to. No, instead of firing straight at her target, the beam of light hit the glass window and, as light does, bounced off, at an angle. Vanessa's next expression was one of realization- after all, it was interesting to see the rules that applied to how this otherwise impossible object worked. Then, trying very hard not to shriek, Vanessa looked down at where the light actually hit.

Bouncing off the window, and darting through the frame of her chair, the wand's beam hit Vanessa squarely in the seat of her jeans. Just like she saw with the coffee cup, the light sunk into her slacks, which pulsed with the glow once... before disappearing completely. Her long, pale legs, covered just a moment ago, were now bare all the way down to her shoes, the only cover below her waist being a pare of black, lacy boyshorts that left most of her cheeks bare to come into contact with the metal seat under her. Quickly, she grabbed her purse with one hand, slamming it over her crotch to conceal herself, but the only thing between her bared buns and the busy cafe behind her were a few metal rods of her chair. With her other hand, she hurriedly pointed the wand away from her, mind racing. This thing couldn't bring things back, could it?
