Jimmy replayed the process of him entering the factory in his mind over and over, not missing out on any detail, starting from his entry to the factory, hearing a sound, entering the building, discovering the suspect, firing his gun, Sam coming in and firing, heading off to the side to flank the suspect, and firing his gun.
