Draco woke to Hermione's face leering over him. Draco sat bolt upright. "WHAT IN THE WORLD?" Hermione looked about, and spotted Ron. "Ron! He's awake!" Draco moaned, "Well obviously I'm awake. What happened? Wait, how long was I out?!" Ron smirked. "Long enough for-" 
"RON! Draco, you were only out for a few minutes." 
Draco stood up, and made his way through the crowd, dodging spells and hexes. He reached the middle of the crowd, and saw that Harry was fighting off a death Eater. He yelled, "Potter! you have to fight You-Know-Who!" Even though they seemed to be nearing the end of the battle, Draco couldn't bring himself to say The Dark Lord's name. Harry looked at Draco and nodded gravely. 
They jogged towards the center of the battle, and prepared themselves for what they hoped was the end of the battle. Draco and Harry were both panting. Harry muttered to Draco, “I’ve got this. Focus on getting the snake.” Draco was confused. “Potter, what in Merlin’s name are you talking about?” Harry glared at him. “Voldemort’s giant snake.  I need you to kill it. You’ve got to use one of these,” Harry said, producing a giant fang. “This is one of the only things that will damage it.” Draco held the fang gingerly. It was covered in blood, some of it was dried, and some was dripping from the tip. 
Draco stared at the fang for a second, and then said, “We’d better get going. I guess it’s now or never.” Harry nodded grimly. They set off in Voldemort’s direction. As they made their way through the crowd, and Draco couldn’t help but notice all the bodies littering the floor and tables.  
They reached the heart of the disarray, and saw a terrible sight. Voldemort was surrounded by powerful wizards and witches, that were all fighting him. Yet the Dark Lord never faltered. He disposed of at least three wizards in just a few seconds. But, when Voldemort caught sight of Harry, he faltered.  
Harry stepped up onto the table that Voldemort had been dueling on, and the whole Great Hall stared at him. Voldemort stared at him with a petrifying gaze. He looked Voldemort calmly in the eyes, and said, “Let’s end this, Tom.” Draco didn’t catch what happened next, and he spotted Nagini in the crowd of people. She was making her way through the people, and he saw her bit a few on her way to Voldemort. There was a shout from Voldemort, “Aveda Kedavra!” And he heard Harry fire a counter-curse. “Expelliarmus!” Draco ran through the crowd of people, who were both watching Voldemort and Harry, and dueling at the same time.  
He lost sight of Nagini, but then quickly spotted her. She was under one of the tables. Draco groaned, but then got on the ground, and crawled under the table. Then, he crawled slowly over to where she was positioned, and gripped the fang in his hand tightly. He lunged for the snake, plunging the fang into her. Nagini was too fast for Draco. Every time that he attempted to stab her, she got away. She slithered back into the mass of people, and Draco followed.  
He ran, and then, once he had his eyes on her, he sprinted to her and stepped on her. He trapped Nagini with his foot, pinning her to the ground. He kept her in place long enough to stab her with the fang, but also long enough for her to lung at him, her fangs sinking into his ankle. He felt a hot, searing pain fly up his leg. The last thing he saw was Voldemort cry out in pain, and see Harry’s final spell hit him. Voldemort was dead. That was all that mattered.
