Chiron is the most bathed out of all King Fire's slaves, but that's because he gets disgusting really quick. The only reason why he doesn't bite the girls during bath time is because he learned that he doesn't get fed if they're bitten. Which took him about a year to figure out.
It's normally the same two girls who bathe him, because he trusts them. Slightly. 1 washes him, and the other keeps him distracted with food
