Brian Cochran is a senior at Trinity. He's very good at math. This talent causes him some trouble when Brother Leon recruits him to do the accounting for the chocolate sale. At first he'd rather do anything but keep Leon's nasty books and put up with his bacon-y breath. But, when the sale becomes a big success, Brian gets caught up in the excitement. He doesn't agree with anything Leon or The Vigils do, but goes along to keep from getting hurt. He's an example of a generally decent guy who simply conforms and goes with the flow.
