You sat beside Percy at the dinner pavilion. Of course he was mad. Nico had to sit alone in complete and awkward silence for an hour. No one to annoy him with their words, no one to make sure he ate, no one to tease him and make sure he had a good time. Sure it was only for one meal, but that was a lot. He'd grown used to the banter and gotten quite attached to you positively. You only say beside Percy because he wanted tips on something. Nico didn't know that so his thoughts were spiraling out of control. You weren't there to ground them. She hates me. She doesn't want to be friends with me anymore. I'm too cold. Told you everyone leaves. Nobody wants a pathetic, socially awkward son of Hades who can't get over his dead sister.

He sat there, starting into nothingness. His thoughts eating him from the inside out, when you walked over.
