(Nah, but are there any people who are sons of Apollo? For roleplay's sake.)

(I mean, we just assume there are general other kids in each cabin, we just don't have specific people. So you could say something like: "Her half-brother escorted her out of the mess hall and to the cabins." or something. I'm not super picky about it as long as you aren't controlling someone else's character. We don't have a lot of guys rping. Only two or three.)
