Quote #4
Chad, Steroid Expert/is also my supplier. And not/just mine. He underwrites/his living expenses dealing/illegal substances. Steroids/are just the tipping-off place. (15.34)
If Chad's willing to supply Sean with steroids, it seems likely that he'd be willing to supply other drugs in the future. Instead, he tells Sean he won't provide any more steroids. It's his version of sibling concern.
