"Are you sure you aren't sick, Percy?" she questioned. Percy shrugged and said it was probably nothing and dragged her into the classroom. He heard Annabeth giggle to herself and say, "Yeah, it would be absolutely ridiculous that I got you sick. After all, you are half god." OR, Percy values his pride and Annabeth is always right.
