Draco understood the weight of his decision in that moment. This was a matter of life and death. How could he, Draco Malfoy, falter when it came time to act? Looking at Dumbledore's accepting stance shattered the icy barriers that he had instinctively conjured on his heart. He couldn't kill the only person who had believed in him. He wasn't that sort of person. He bit his lip as he raised a shaking arm towards Dumbledore. The wand in his fingers felt foreign. His heartbeat pounded in his ears as he tried to muster the words to end a life.
