Shamus saw the gun in the stranger's hand the moment he approached the light, and instinctively raised his hand in the air, before lowering them with a chuckle. "Good day for a sewer adventure, aye mate? Nice revolver you got there by the way, it really brings back memories from the old days. Anyway, what in the hell are you doing down here mate?" Shamus said with a smile, lifting his shotgun out of its holster with his good hand, cocking the gun just in case.
