Panicked, knowing that he's going to kill you regardless of your behavior, you reach for your weapon. Tommy, who is used to this sort of situation, fires a bullet into your stomach. You know what's going to happen now; you're going to bleed and suffer for the next half hour until you finally fade out. You know this so, even as the car is drifting to the side of the road, even as your hands shake and your vision blurs, you keep reaching for your gun. This time you get exactly the outcome you wanted; Tommy fires two more into you, putting you quickly out of your misery.
