It was Zoe, Jon's sister and one of the goth chicks. She was mad because Zoe was a natural blonde and she chose to dye it a dull black. She really wanted to see how her powers worked on girls. She walked over to wear Zoe was standing.
"You can disappear, Bitch." Zoe remarked.
"I could or I could do this." Sarah replied as she touched Zoe.
Zoe's body didn't undergo any radical changes, but her hair returned to its natural blonde. Her clothes changed into a camo jacket with an AC/DC tee and black shorts with black hose and black boots. It was how Sarah thought goths should dress.
"How's it going, Sarah?" Zoey asked her.
She then realized that the way that she was doing this was inefficient. She had to come up with a way to do it better than one person at a time.
