No one ever asked him if he ever was involved at all with the Harper incident but it was just as well, he would have just lied to them if they did. It had taken him a while but he had learned that selective truths were the ones to feed to the masses. If one were to ever tell them the /whole/ story then they lost any advantage that the could have gained.
Actually, he had learned it from Jack but then again, he learned more than he would ever care to admit from the man. He'd been taught everything by the other and Jack was the reason that he's the man he is today. Though, of course, he would never speak a word of that to anyone else, if they knew that he'd been traipsing about with the reefer fiends that he seemed so passionately against , what would they think?
Not that he really cared of course, it just made things easier for him if they didn't know.
