Louisa jumped as a boy called out. Shouldn't people check if they were too close to someone before shouting like this? She looked at the boy and recognized him from the Flying Final- yes, he was recognizable because he was stuck in the air on his broom and she almost fainted imagining herself stuck up there instead of him. "Hey! Lower your voice!" She said, rather annoyed but walked up to him. "Do you know someone called Kita Lewis? She's a badger like you." Not literally but...he should get the reference easily.

Besides, he shouldn't ask why Louisa should look for the girl herself. That would only make things impossible to explain and the Ravenclaw stayed away from any kind of explanations.
