Sam had already come up with a plan; all he needed now was for Bobby to break the array, then he'd be able to complete the mission and even take the rewards from the inheritance. As for the 30% of the treasure Sam had promised Bobby, he obviously wouldn't follow through. After all, why should he? His original goal was to kill Bobby anyway. As long as Bobby broke the array, once they were inside, Sam could kill him, grab the treasures, and at the same time, he would be killing two birds with one stone.
Bobby inspected the hill where Marcus had disappeared. "Bobby, I heard you have a talent for arrays. You think you can break this?" Sam asked in a friendly manner. Everyone looked at Bobby with expectation in their eyes.
