It had been quite a while since Samuel Anders had set foot in a Camp Half-Blood arena--more than a year, in fact. When he'd left, he'd been severely disillusioned with the place, specifically the notion of training a bunch of teenagers to save the world. Sure, a demigod's life was never easy, but despite that, far too many of the campers were still too soft and too undisciplined to be ready for war. They cared more about being popular and getting dates and other frivolous things. They hadn't experienced the streets like he did.
That was Samuel's opinion, anyway. It was not a popular one. His being blunt about it had given him a bad rap with quite a few of his fellow campers. He had never been a people person to begin with, but this level of alienation at camp had been a bit unpleasant, even for him. So Samuel had left, thinking that it was perhaps better to strike out on his own. He had hitchhiked throughout the States, killing monsters whenever they came his way. It turned out to be a horrible time, and Samuel had wondered what he was even doing. A few dreams from his father, Morpheus had convinced him to return to camp.
So here he was. Samuel still didn't trust that the average camper had anything to teach him about fighting or survival, but it was either give them a chance or return to the streets, being constantly hounded and alone. He nodded towards the girl already there and took a seat on a nearby bench, waiting for her to do something.
