Yeah....so an old country dialect when he gets angry and a big scar on his back from Luffy...
I can't think of any time that luffy gave someone a scar on their back, maybe this guy was from before the storyline?

You know....I get the feeling Caimie's situation will eventually be handled by the mugiwara buying Caimie's freedom from the gangs that keep hassling her. They're really only in it for the money, and Luffy's crew just came across a shitload from the previous arc. (Plus good guys never hold on to any wealth without it having to be spent or stolen by the next arc...)
