After fighting? [Zelos tips his head back to give Yuan a weird look.] Everyone gets hungry after sparring. Even the guards get hungry after sparring. Is it different for half-elves?

[Zelos hasn't known any half-elves well enough or near enough to compare them to the human soldiers, but he knows they have long lifespans. Maybe they also only get hungry once a week or something. That would explain why Yuan never leaves the library.]
