Title: The Coma
The italics are not, I repeat, NOT a flashback. Everything else is.
Muttering "Expelliarmus", he caught Voldemort by surprise and managed to disarm the dark lord.
Harry was just about to finish the dark lord off once and for all when a memory forced its way to the front of his brain, ceasing all other activity. Obviously Voldemort was using his talent at Legilimency. Any hesitation was dangerous, as there was a room full of armed Death Eaters ready to kill him, but there was nothing he could do, so he succumbed to its power.
"Help!" a woman's voice yelled to Harry's right. The voice was distant, but clearly distraught. "Someone please help!"
Without thinking, Harry immediately turned towards the yell, raising his wand in the process. He saw a family of three, father, mother, and son, lying on the ground and breathing heavy. Just above them was the dark lord, smiling his infamous smile, reveling in the pain he was causing.
"Help!" the woman called out again. Voldemort laughed and said something that Harry couldn't hear from his distance. He had frozen when he saw Voldemort, something that he knew would be detrimental in the future. As a punishment for yelling, Voldemort subjected her to the Cruciatus Curse.
By now, Harry had composed himself and sent a Patronus to all three camps, Gryffindor, Hufflepuff, and Ravenclaw. He ran flat out towards Voldemort, ready to stop him before he killed the family. As he got close, he saw that they were worse then he thought. The man was lying unconscious on the ground, deep gashes on his face. The son was kneeling on the street, but swaying slightly, clearly about to lose his consciousness as well. The woman was also kneeling, but fully aware of the situation, calling out for help as tears ran down her face.
All around the street, there were Death Eaters looking on with excitement. Some were looking around, trying to find someone else to torture, but others were just standing there watching as if this were the Quidditch World Cup. No, Harry just called it the Muggle-Killing World Cup. The teams were Voldemort and his Death Eaters versus everyone else. Guess who was winning.
Behind him, Harry heard several pops that meant others had come to join him. Unfortunately, the Death Eaters had heard the noise as well. This was going to be a long night.
The memory was detailed and Harry could feel the emotions that were tied to it, so he was slightly glad when the scene changed. Out of the corner of his eyes, he saw Voldemort slowly retrieve his wand.
Harry was walking away from the castle, determination written on his face.
