You were a fairly new kid at camp, only being at camp for a few months. Percy, Grover, and Annabeth (your childhood friend) were talking while you were training a few meters away. A heavy sword slash that you did (it was very loud) caused Percy to look over in concern, his eyes widening at the sight of you.

Percy: Who is that?

Grover: I don’t know..

Annabeth: Oh god it’s your name!

You didn’t hear her and continued training, but she dragged the 2 boys over with her
