Amy stands on the other side of the window, betrayal, hurt, anger, and hate shining through her eyes.
Because by hugging Mom, I sided with her, and stood against what Amy was going to do. I left my sister, and took the monster's side, the way she sees it. I pull away from Mom, and try to pretend everything is okay. Nothing is, though, and she knows it. She tilts head to the side, a question in her eyes. I point behind her, at the window, and Amy's eyes widen, and she runs. Mom turns around too late, and turns to look at me, even more confused than before.
"Amy," I whisper. "She wants to kill you."
Mom picks up her paper and pencil. And she writes:
Let her bring whatever she's got for me. I might die. I may suffer and have to deal with it for the rest of my life. But I may also deal it right back at her.
I meet Mom's eyes with a new resolve, a new purpose. She is now Amy, and Amy is now her. The villain and the victim have switched places. And I'm stuck right in the middle of all of it.
