Hes just a business partner of Kelvin, I don't think he's ever claimed to be involved in the club, just people speculating and wishful thinking. But yeah, a weird time to decide to call him out when he very obviously will have more important things to be dealing with.
I doubt Shoey had any inkling about that story, or indeed any connection Shaq had to it. I certainly didn't, and I suspect a majority on this board won't have either.
