Harry Potter and the Son of the Sea

Harry couldn't get past the striking fact that one of the three American transfers from Ilvermorny was so similar in appearance to him. "You're right Harry. Unruly black hair, green eyes (though a different shade) same mischevious glint in his eyes..." Hermione began.

"Does it look like I know where to find a bozo?" The exchange student said staring fearlessly at Snape.

"Same sassy replies." Ron added.

"It's a Bezoar, Mr Jackson." The potions master replied to the boy.

"I don't give a whooping bag of Hermes' divine wind." The American snapped. "And you know it."

"Detention."

"That's a okay with me. I can't express my undying adoration for this class then." Harry snickered at the amount of sass and sarcasm the boy managed to cram into every syllable.

Yes. Perseus Jackson was a strange boy.
