Cal was talking in a low voice to Mrs. Casnoff. I saw her look over his shoulder at me, and wondered how she felt about me leaving for the summer. She was probably pumped, or as pumped as Mrs. Casnoff got. God knows, I’d brought nothing but trouble to Hecate Hall.
Pumped up with adrenaline - excited. (In Br English we would normally say 'pumped up', but 'pumped' on its own is used sometimes - especially in a sporting context.)
