rio's father was a patch up until he and his wife died after being hit and killed by a drunk driver. but he was always a trouble maker, family and the club are everything to him and the only two things he'd drop absolutely everything for in the blink of an eye. rio's quick to anger and tends to react with violence first then questions, he's also still very much a manwhore but aside from all that he's an okay dude even though he doesn't like to show it.
