Draco panicked. His eyes adjusted to the darkness, and could make out strange figures coming through all the entrances. Death Eaters, he realized. Draco saw many teachers cast shield charms, and cast one of his own. Around him, duels were breaking out between Death Eaters and students. Draco saw Luna Lovegood and Neville Longbottom battling Narcissa. 
Draco ran over to help. As he reached Luna and Neville, he cast a shield charm to protect them. Neville looked astounded that he was helping them, and Luna looked a bit amused. Taking advantage of the slight pause in the fight, Draco, his heart pounding against his rib cage, stunned both his parents. As he, Neville, and Luna ran, he looked over at his mother and whispered, “I’m sorry.” 
Draco spotted Harry, and ran over to him. He was fighting against a Death Eater that wouldn’t stop laughing. The Death Eater cackled, and sent a killing curse right at Draco. Draco couldn’t move. His legs had turned to jelly. Something jumped in front of him. With a start, Draco realized that it was Pansy Parkinson.  She fell to the ground, and out of the corner of his eye, Draco saw Harry stun the Death Eater, who, he realized, was Bellatrix. He knelt, but realized that Pansy was dead. He was startled to feel a tear on his cheek. He brushed it away, and got up. He looked around for Bellatrix, but could not see her. She had run after killing Pansy.  
Draco ran over to the table on the left of the Great Hall, and stood on it. He watched the duels, looking for one person in particular. He spotted her and ran through the crowd. As he approached, he could see that she was dueling side-by-side with his father. The two of them were dueling Molly Weasley, Seamus Finnigan, Dean Thomas, and Lee Jordan. When Bellatrix saw Draco, she laughed and sent a curse straight at him. He dodged, but his father looked horrified. He walked over to Bellatrix and punched her. “NOT MY SON!” Draco’s stomach lurched. Lucius had let his guard down. Draco saw his aunt push Lucius away, right into the stream of green light that had come from Molly Weasley’s wand. In the few seconds before Lucius got hit, he turned, saw the curse that was coming for him. He stared at Draco, stared him right in the eyes, and then he was gone. 
Draco saw his father fall, just like he had seen Pansy and Crabbe fall. He saw his dad’s head hit the ground, and he screamed. He felt a deep rage rise in him, and tears were streaming down his face. He turned to look at his aunt, who was still aiming curses at him and the Gryffindors. He glared at her and yelled. “YOU! YOU KILLED HIM! YOU ARE GOING TO PAY!” Bellatrix looked startled, but then regained her senses. She yelled, “I DIDN’T KILL HIM! THE GINGER DID! ANYWAYS, HE IS BETTER OFF DEAD. HE HASN’T DONE ANYTHING FOR THE DARK LORD, SO HE IS IN HIS RIGHTFUL PLACE.”  
Draco couldn’t believe what he was about to do. He was torn, but the thought of his father made him certain that he was doing the right thing. He stared his aunt dead in the eyes, and shouted, “AVADA KEDAVRA” He saw his aunt hit the floor, and he turned away. He was startled to feel a tear drip down his face.
