It was after lunch, as we were walking to the Gryffindor Common, that the nausea returned; threefold. Not wanting to scare Harry, Ron and Ginny, I told them that I was feeling tired and wanted to sleep again. They nodded and watched me turn around and leave. Once I was out of sight, I started running, my hand clasped in front of my mouth. 

Several students stopped to see their Head Girl dashing by, and, I, oblivious to all, pushed through the crowd, afraid to yell “Excuse me!!” for fear that I might…lose control.
