The Doctor stepped out of his Tardis with a grin. He was visiting an old friend because this was supposed to be an important day for the old wizard. What he saw disturbed him. In front the courtyard in front of him, a young boy that Albus had talked about so much was firing a red stream at a pale, bald, malformed monster, more akin to snakes than to any human. From the snake man shot out a stream of green fire. "Ah, Voldemort," he said, sad. The Boy Who Lived, the one that Albus had taken as his student, as his apprentice, was not going to defeat this one on his own. The Doctor recalled his last conversation with Dumbledore.
"You must make sure you are there, Doctor. It would mean very much to me," insisted the old wizard, gesturing with his wand at the paper. "If you don't I'll fear that things will happen that we must prevent."
"Oh, of course. But you look like a man that has something else to say," said the Doctor to Dumbledore.
"Yes, well, there will be a man there. A man named Tom Riddle. Call out his name, and when you know who he is, place this crystal in your screwdriver. With it, you'll be able to affect wood. His is all I can say," said Dumbledore, handing the Time Lord a slightly yellow crystal with the carving of a snake being stepped on. "It will only be usable once, so use it well."
"Alright, Anything else?"
"Take these vials. They can restore life."
"Wait. That's not possible. Only Gallifreyans can regenerate."
"And now you know why I asked for your blood."
"You did this?"
"No. A rather gifted potion master did. When he learned of my plight, he asked that he not have one himself. He would be at peace with himself."
"I'll keep that in mind."
The Doctor placed the crystal in his screwdriver, in a compartment used for enhancement when needed. He looked at them and yelled out "Tom Riddle!"
The Dark Lord looked his way and with a flick of his wand sent Harry flying through the front door of Hogwarts. "And what muggle is this that challenges Lord Voldemort?" he demanded.
"Not a muggle. Not a wizard either. Tell me something, Voldemort, do you believe in aliens?" asked the Doctor casually, screwdriver hidden by his body.
"I have no need to answer your questions, and you are of no use to me," said Voldemort, swishing his wand at the Doctor. "Avada-" The Doctor suddenly pointed his screwdriver at Voldemort.
"Don't make me use this," he said, looking angry. The sudden change came because the Doctor recognized the spell, recognized what it had done.
The Dark Lord was stopped, but only for a moment. "Avada Kadav-" Before he finished his words, a buzzing sound filled the air and the elder wand snapped in Riddle's hands. It exploded into green light and Voldemort was on the ground, screaming. "Help me! Help me!" He screamed, face burnt.
The Doctor picked up the broken fragments of the wand, stuffing it into his pocket. He pulled out a two vials and handed called out to Harry. After a while, he came, and the Doctor handed him the vials. "Give these to Tonks and Lupin. It may save their lives," he whispered.
"Why don't you just kill me, Doctor? Do you think yourself merciful? I'll just be carted off to Azkaban now, mortal, waiting for death. Or they'll take my soul. Kill me." pleaded Voldemort. The Doctor stayed silent. "Why don't you yell at me about honor and friendship like Potter would have?" spat the dark lord. "Why don't you shout your victory? Why don't you celebrate?"
"Because it would be wrong." replied the Doctor. "You have suffered little that isn't self-inflicted, and yet you blame the world for your misery. You slaughtered your own father for immortality. You framed your supposed 'pureblood' family. You have done so much evil, and yet... I pity you. You are the lowliest creature I have ever met. The opposite of everything I believe in, and yet I don't hate you. I want to help you."
Minerva limped through the castle doors. "Hogwarts is secure. He has no power now. We'll put him in the dungeons till the authorities arrive, Doctor," Mgonigal shook her head. "To think that my father's stories of you were real. Its almost as amazing as wizards must be to muggles."
"Oh, more than that. We all believe we are the premiere beings of the universe. You just have a group with less power that believe themselves above all others. I'm more to you than you are to a normal person." replied the Doctor. "No. Not a cage. A nice soft one for somebody that's sick.
"He's killed so many people, though."
"A dungeon is for somebody that is a danger. This one is no such thing."
"LOOK AT ME!" screamed Voldemort. He screamed it again. "LOOK AT ME! I AM SPEAKING TO YOU!" spittle flew from his lips. Mgonigal looked his way, startled, but the Doctor shielded the dark wizard from view.
"Don't look. He's beaten. Don't obey him. He doesn't matter any more. Come on. Let's see if we can help anyone inside. Neville?" The boy who killed the snake looked up. "Please grab Tom for us and put him in a good bed. He's sick and somebody needs to take care of him until he can get more permanent quarters." The doctor strode through the doors. "Never thought I'd be here with the castle looking like this."
"You must have been a friend of Dumbledore," said Mgonigal.
"Yeah. Say, where is he?" asked the Doctor.
The professor looked down. "Gone."
"Oh. That's a shame," he replied, truly sorry for the loss. He was a good friend.
Lupin and Tonks came through the great hall doors, grinning, Tonks hugging the Doctor. "Thank you for saving us. We wouldn't be here without you."
"Well, its all in a days work for a time lord. Say, how is Harry doing?"
Everyone gathered together, answering his questions and asking some in return, happy to be alive. Everyone except George Weasley.
The Doctor calmed the crowd and pushed people aside to get to him. "I'm so sorry for what happened."
"Fred knew the risks. I just can't believe he's gone," said George. A tear fell from his eye. The Doctor knelt down next to him, and planted his hand on the young wizard's shoulder.
"It'll be okay. You'll see him again. I know this for a fact." said the Doctor. "Just live your life the way you know Fred would want you to." George nodded, and the doctor walked over to Harry Potter. "Here's the wand. even broken, it should fix yours."
"What will you do now, Doctor?" asked Harry. A grin broke across the Doctor's face.
"I'm going to go everywhere. You are going to become a great man, and you will only have one regret in your life. It won't be a terrible one, and it'll be a joke for you," the Doctor said, a twinkle in its eye. "Don't worry about it. Oh, and give this to George. Tell him that it was a gift for Fred and that Fred should still have a taste of it." He pulled out the last vial and gave it to Harry.
"Wait, where are you going?" the Chosen One asked.
"To fly with dragons," he said, walking into his blue box. "Enjoy the day. Visit Riddle. In a week, tell him that the scarecrow boy was right all along." And with that, the Tardis made its whooshing sound and it was gone, carrying our favorite alien into Alegasia. He stepped out of the Tardis, a grin on his face. He knocked on an herbal shop, and waited. A woman with red hair answered the door. "Hello Angela. What have you been doing?"
