i have vague ideas ... he owns an illegal underground fighting ring basically and he's somewhat of a debt collector for it (i.e. beating ts out of people within an inch of his life). he has those brass knuckles but he honestly don't need them, partially has them for the aesthetic ... its sort of a family businesssss i think. he participated in it when he was younger, like 16, and he began with dogs but as he got older it was other people. he's 29 now and still peak i fear His design Is In The Works!
