She thought I was going to fight the top scholar for credit, and stopped me from leaving. I placed the final page he had added in front of me. "Since your name is on it, you can answer for it from now on. Whatever mess comes of it has nothing to do with me." In that moment, the smile faded from the top scholar's face.
