The servants and the like were of no interest to Jimmy, and he didn't want to slaughter these defenseless people, so he didn't go back to the backyard. After replacing the magazine in his Glock, there weren't many people left in the main building, and considering the intense gunfire earlier, the fact that none of his people had come inside to report meant they probably realized their security was in dire straits.
Jimmy looked up at the people in the house; a few were scattered across different rooms, seemingly aiming their weapons at the doors. There was one person crouching at the top of the stairs on the second floor, probably planning to defend the staircase. From his position, he could oversee the entire foyer, including the front door—a skilled man, far superior to ordinary gang members.
