'blah' mean thoughts
It was a late night at Hogwarts School of Witchcraft and Wizardry. A lone figure stood in the Entrance Hall, not caring if anyone saw him. A storm was raging outside, and he was not able to hear it in the dungeons. Violent storms usually kept people up, but for Draco Malfoy, it was soothing.
His dorm mates, sixth-year Slytherins Vincent Crabbe, Gregory Goyle, and Blaise Zabini, were sleeping, when he snuck out of the Slytherin House. Footsteps were heard over the thunder, and still Draco did not move.
Draco didn't move an inch nor did he turn to face the new-comer. A hand was placed on his shoulder, under which was felt neither twitch nor flinch. This lack of movement scared the new-comer. It was like Draco had been petrified. The new-comer turned to run and get Madame Pomphrey, but was halted by a voice. "Professor."
The professor turned and looked at Draco. His silver-blonde hair was worn loose, ending just above his shoulders, covering his ears. Draco then turned to look at his dark-haired professor.
"What is it, Draco?" Severus noticed unshed tears in Draco's eyes. "What's wrong, Little Dragon?"
Without answering, Draco flung his arms around Severus. "Severus!"
Severus wrapped one arm around the sixteen-year-old Slytherin. Quickly and gently, the Potions Master tucked Draco's hair behind his ears.
Draco felt his Head of House go rigid. "Severus?"
"Come with me, Draco."
Draco nodded and, unconsciously, un-tucked his hair, once again covering his ears. Severus led Draco to his office. Severus said something in a language Draco didn't understand, but had heard his mother use. The door to the office opened, and the two Slytherins entered. Draco had been in the Potions Master's office before. It was one of his favorite places to spend his time.
"Stay here, Draco. I'll be back in a moment."
Draco sat in one of the chairs in front of the fire and looked around the room. There were a couple certificates (including his diploma from Hogwarts) whose light-colored frames contrasted with the midnight blue walls and black ceiling. On one wall there was a large tapestry depicting a large serpent and a raven-haired Slytherin with the words The Heir of Slytherin at the bottom. The opposite wall was covered completely by shelving. Resting on the shelves were potion ingredients, most of which Draco had never handled himself. Stuff like Lobalug Poison, Runespoor Eggs, Powdered Romanian Longhorn Horns, Jobberknoll Feathers, and Frozen Ashwinder Eggs were on the lower shelves. The higher shelves held the more dangerous and magical ingredients, such as Erumpet Horn and Tails and Exploding Fluid, Dragon Hide and Blood and Hearts and Livers and Horns, and Unicorn Horns and Hairs. The highest shelf, however, was completely empty, except for a raven which at the moment was sleeping. On the adjacent wall was a bookcase (as well as the door Severus had gone through). Several titles of books stood out at Draco. Titles such as "Fantastic Beasts and Where To Find Them," "Quidditch Through the Ages," and "1000 Magical Herbs and Fungi" were familiar to him. There were several other potion books and just as many Defense Against the Dark Arts books. A desk was next to the bookcase. Normally, it was devoid of any clutter. So, it shocked Draco to see a few rolls of parchment, an ink bottle, Severus's green and black quill, and a couple of books on the desk. The sixth-year Slytherin got up and walked over to the desk. The books didn't look too interesting to Draco as one was on Werewolves and the other Vampirism. Draco picked up one of the rolls of parchment and, expecting to see a potion recipe, unrolled it. To the silvery-blonde Slytherin's surprise, it wasn't a recipe. In fact, there was nothing written on it. This confused Draco. 'Why would Severus keep a blank roll of parchment on his desk?' Shrugging, Draco rolled the parchment back up and laid it on the desk. Curious as to what the other rolls of parchment were, Draco picked up the next one.
Severus, dusting off his robes after flooing to Malfoy Manor, was greeted by Narcissa Malfoy. "Hello, Severus."
"Is Lucius home?"
"No, Sev. He's not."
Severus drew the silvery-blonde woman into his arms. "Our suspicions have been confirmed. He did inherit the genes."
Narcissa pulled back and smiled at him. "Sev, we knew he would. How could he not? We both have the genes, my love. It was only a matter of time before his Elvin characteristics began to show themselves."
"I can't stay too long. I left our son in my office." Severus turned to leave. "Maybe you should come with me, and we can both explain to Draco."
Narcissa nodded and both of them flooed to the staff room, where Severus led both of them to his office.
Draco had finished looking at the rolls of parchment. Aside from the blank parchment, there was a potion recipe, an essay done by a Ravenclaw, and a document written in a language Draco didn't understand.
Severus peeked back into the main room of his office. Draco was curled up in the chair, sleeping. The Potions Master turned back to Narcissa. "He's sleeping, Narci. We should tell him later. When is Lucius due back?"
"Not for a few days."
Severus nodded as he pulled a blanket out of a trunk. It was green with the word 'Slytherin' embroidered in silver on the front. The 'S' of Slytherin was a snake. He carried the blanket into the next room and over to Draco. Severus draped the blanket over the young Slytherin and knelt down in front of the chair. He reached out and tucked Draco's hair behind his ear, revealing his pointed ear.
Narcissa came up beside Severus and looked at the young Elvin boy. "He looks just like you did at the age, Sev, but with my hair color and a combination of our eyes."
"That he does, Narci. That he does."
The silvery-blonde woman smiled and tucked Severus's hair behind his ears, revealing his pointed ears. Severus smiled at her, stood up, and led her into the adjacent room, where they sat in chairs that were facing each other and talked about everything from Draco to Lucius to Voldemort and his Death Eaters, back to Draco to the classes Severus taught.
It was still dark out when Draco woke up. He recognized where he was immediately; Severus's office. 'I must have fallen asleep,' Draco thought. He was about to go back to sleep when he heard the soft murmur of voices in the next room, both of which he recognized. He got up, leaving the blanket in the chair, and walked into the adjacent room.
Severus and Narcissa were still sitting in the chairs, but each now had a cup of tea in front of them.
"How has Draco been doing in Potions?"
"Very well. Near the top of the class."
"That's not surprising, Severus. You were too."
"Mum?" Draco's tired voice interrupted the conversation. Both Severus and Narcissa turned and looked at him.
"Did we wake you, Little Dragon?"
Draco shook his head in response to Severus's question. "Mum, what are you doing here? Is Father here?"
"I came to see you, Draco. Severus is here, but Lucius is on a business trip," Narcissa replied, not realizing her slip-up. "Come here, Draco."
Draco didn't notice his mother's slip-up either. He walked over to her and she pulled him onto her lap. Severus smiled at mother and son. Draco had a small enough frame that, even at sixteen, Narcissa could still hold him on her lap.
"Severus, what time is it?" Draco yawned.
"Time for you to go back to sleep." Severus stood up and walked over to Draco and Narcissa. Draco looked at Severus and furrowed his brow.
"Severus?" Draco stood up and reached up to touch Severus's left ear. "Your ears are pointed."
Severus caught Draco's hand. "Yes, Little Dragon. Just like yours and your mother's. It's an Elvin quality."
"Elvin? You mean, I'm part Elf?"
"No, you're full Elf. Woodland Elf to be precise. Narcissa is full Elf, Lucius isn't Elvin, but I am," Severus replied, gently.
Draco thought about this for a moment. Then, he looked at Severus. "So, that means you're my father?"
