She grabbed her books and shut the door. Then she walked away.
"What about Zach?" Jessica asked.
Yukio didn't answer her. She just quickened her pace. She had to keep away from Melissa at all costs...and preferably any of 'evil' Yukio's friends, who weren't much better. Picking on Melissa made her feel horrible, but it also produced a wonderful feeling within her, like a drug rush. She was afraid she could grow addicted to it...or worse, turn into 'evil' Yukio for good.
But how could she keep away? She ducked into a classroom. She'd write Melissa a note. Explain things and tell her that she couldn't control herself. As she began to write the note, she felt that 'switch' flip again.
'Evil' Yukio put the pen and paper back in her bag and headed into the hall, toward her prey. She wrapped her arms around Zach admiringly, knowing how to get him riled up rather quickly. Zach really isn't a long term prospect, she thought. But he's certainly fun in the short term.
The 'old' Yukio wasn't aware that any communication with Melissa would bring on her other self for a time. Fortunately, since bullying Melissa was something 'evil' Yukio did regularly, it wouldn't be long before she lost control.
For now though, 'evil' Yukio was all focused on her own pleasure and manipulating Zach into doing whatever she wanted. And she had some ideas.
