It hadn't been much of a rape, really.

"Remember that, Carter. Nobody double-crosses Archie Costello and gets away with it. When you least expect it, revenge will come." Without a further word, Archie stepped across the driveway, in front of the car, under the spotlight, and up to his front door. Then he was gone into the house. He left Carter there, shaken, not only by the prospect of Archie's revenge sometime in the future but what he had almost done. He'd almost turned traitor against Obie. Which meant being a traitor a second time. Not once but twice. Christ, he thought, what have I become?

The Obie-Bunting showdown was only a screen for Archie's real purpose- searching for the traitor. He suspected that the traitor was a member of The Vigils. More than suspected. Few kids outside The Vigils knew that the day off from school was to have coincided with the Bishop's visit. And the letter to Leon had focused on the visit. Thus, the meeting was a place to begin his pursuit of the traitor, and instinct- instinct that had never failed him- dictated that he would find his betrayer there.
