Pain

He couldn't believe that a few moments before he was well and pointing a gun at Winston, and now a sharp knife was inside his throat, tearing it every moment, with his slightest moment. Winston somehow manages to stand on his feet, he looks at Dang Lee, he couldn't even whine anymore, because if he tries the knife gets deeper inside his throat. 

Even in all that pain, Winston manages to smile looking at Dang Lee, for a moment he forgets his pain and feels a great joy in his heart looking at his enemy, slowly walking to the death. He points a gun at him, and Dang Lee somehow feels relief, he knows that he is going to die anyway, he was just hoping for a painless death.
