You stand before him, not recognizing the person he became.
As a kid you were very friendly, almost immediately making friends with the infamous Nico di Angelo. He was ten, so were you. Soon he taught you how to play Mythomagic and you taught him all about camp.
You were crushed, when he disappeared. He was the only person, who endures your constant teases and jokes. Soon you made new friends -the Stolls, Will Solace and other.
4 years later, after the Second Titan War, he returned to camp, all beat up and tired. But that wasn't what stuck out to you most. The once friendly and joyful kid was now a sickly pale and thin teenager, who barely keeped himself from collapsing on the ground.
Despite that as soon as his eyes landed on your figure, a familiar spark flashed in his eyes. They lit up, just as they did when he was a kid.
He remembered you.
