Clarisse was a bully, everyone knew that.

Hence the reason why they were all so confused when they saw you lecturing Clarisse shamelessly after she had attempted to dunk Percy's head into the toilet, and Clarisse wasn't even fighting back.

Her head was low as she actually started to feel bad about what she had done, because you were now mad at her. Everyone knew that you were like a nanny to camp, someone that comforted everyone, stopped people from having fights, and lectured anyone that did so.

They just did not expect to see you actually lecture Clarisse, and for Clarisse to genuinely regret her actions, since you were made at her now. She didn't like this, when you yelled at her even if you had the right to.

But of thing was for sure, Clarisse wasn't going to fight back to the one person she looked up to.
