The fire went on. Hogwarts Castle was burnt down completely. Harry Potter, Luna Lovegood, Susan Bones, and Draco Malfoy came together in the middle of a burnt area that used to be under the Great Hall. Luna and Susan could not keep their contempt of Malfoy off their faces. Harry, however, was calm.
"We must rebuild our home together. As four representatives from each house, we must work together. Luna, Susan, I know you may hate Draco, but in reality he is just a cowardly boy who has had a bad influence. Forgive him and move on. Hogwarts will be great again, and you will see your children leave from platform 9 ¾."
Draco sighed, and said, "I know I have done wrong. And, I am really sorry. Please forgive me this once. I may be a Slytherin, but I will act better from now on."
Luna, who never held grudges for long, replied, "I forgive you, Draco. It's not your fault really. Voldemort is a really mean guy."
Susan, as loyal as the first Hufflepuff, croaked out, "I forgive you too. But don't think I'm going to let you off that easily. One wrong move and you're in Azkaban."
Draco smiled weakly, "Of course, Susan."
"Well it is time. I trust you all know what to do." Harry lead the others by pulling out his wand. Just as the sun rose above the horizon, all four representatives raised their wand and pointed up at the sky. Hogwarts Castle rose again. Like in the muggle movies Harry had seen, sparkly dust rose above the growing walls, and with one last shine, the sparkle disappeared as the wall met at the top of Hogwarts. With the healing of Hogwarts, Harry's scar also disappeared, Luna recovered a memory of her mother, Draco gained the courage to speak with his crush, and Susan learned how to communicate with her idol, Helga Hufflepuff.
19 years later, Harry was seeing his children off to Hogwarts. His scar had not hurt for 19 years, because it was gone, although the memory of it will always be there, just under the skin.
