Mandel's OCD, so he'd be paranoid. Probably already knows about the Serial Piller, but is doesn't want to show his hand (or briefcase #16 for that matter). I heard that one point KITT was to be played by Mr. Martin Balsam, but he's been dead for yonks, so I don't place much stock in his replacement. Easy money on Mr. Feeney, unless Vader does a run-in.
