Ian and Nico
Nico liked being outside at night. It was nice out here, and dark, and safe and he liked the fire much more than the lights of the city. He didn't know Magnus well, but he knew that he was related to Annabeth, so he had to be okay. He hoped.
He'd had his share of food, and right now was trying to find a place to sit that wasn't too close to the rest of the people, but wasn't too far away, either. He didn't always enjoy socializing, but he did like listening.
As he sat, the boy next to him (who had obnoxiously red hair that might have blinded him if it wasn't night) offered him a beer. Nico looked at it for a moment, as if deciding if he actually wanted it, then shrugged and nodded as he took it and sat down.
