“As I went to stand up, I felt a tiny point of pressure on my back."Don't move," Kasey whispered.I stayed bent over."Drop the knife," she said."Excuse me, I'm using it," I said.She swallowed hard. "For what?""Mom and Dad. You."The pressure on my back increased. "Drop it, Alexis."Drop it? Like I was a bad dog running around with a sock in my mouth."How long will this take?" I asked, setting the knife on the floor. "I'm in the middle of something."Get in the bathroom," she said.The faster I indulged her, the faster it would be over with. So I walked into the bathroom. She followed, kicking the knife toward the end of the hallway and flipping on the bathroom light. "What's this all about, Kasey?" I asked, turning around. At the sight of my face, she gasped, and the point of the fireplace poker she was holding wavered in her hands. I realized a second too late that I'd missed my chance to grab it and smash it into the side of her head. "What's happening to you?" she whispered. I glanced in the mirror. The darkness had begun to spread from my mouth and eyes. It leached out in inky puddles with thin tendrils of black snaking out in delicate feathery patterns.What's happening to me? What was she talking about?"So you have a pointy stick," I said. "Big deal. get out of my way.""What are you going to do?" I sneered. "Poke me?"'I'll hit you, Lexi." Her face was stony. "As hard as I have to."Whatever. I'm really not in the mood. "Can we talk about this in the morning?" I asked. After I kill you?"No," her eyes hardened. "Get your toothbrush.""What?""Pick up your toothbrush, and stick it down your throat.""Kasey-""Do it," she said."Ugh, fine. You're sick, you know that?""Get in the tub.""Happy?"I stuck the toothbrush into my throat. Instantly, I gagged and doubled over."Do it again," she said."God Kasey," I cried. Stabbing people was one thing. But making them barf- that was just disturbing.”
