I think Dave is going to be billy's demise, he'll soon have Billy peddling steroids or gh, and billy will think he's all cool, and wind up taking the fall for palumbo, this is a hypothetical situation of course...or Billy will get all friendly will our buut buddy Derek and then Derek will start pimping him out to his shabbier clients that have trouble coming up with condom money, and he'll wind up taking the dick for Derek.
Billy doesn't need the money.
He makes over 100k a year! (He's MS certified, ya know)
