What Cassandra didn't know is that everything that happened during her demonstration was intentional, except for the light bulb thing. Spark had been altering the lights in order to put on a show for everyone because that's what Vlad had ordered. In fact, Spark had constantly been using her powers since she acquired them. It was like learning to use a new gun or knife, she was always practicing in order to master her new tool of the trade.

"You think whatever the fuck you want then. I don't have to explain myself, tch." Spark leaned back in her chair with her hands behind her back. These people were really getting on her nerves and she was doing all she could not to start a fight right there in front of Vlad. It was strictly forbidden for Spark to attack any of the other experiments unless she was explicitly ordered to do so. He had made that clear when he recruited her. Spark tried to ignore them by staring at the ceiling but all she could think about was breaking noses. She needed to be away from them soon or she was going to explode.
