Chapter 2

"Why, I am growing quite sentimental. But look! My true family returns."

When Harry Potter became eleven, he received his Hogwarts-letter and - after a bit of struggling with the Dursleys - he went to Hogwarts. There he met his little brother Draco (not that they knew they were brothers.), but from the beginning on they were sworn enemies.
Severus knew Draco and Harry were his sons, but as Harry was in Gryffindor and Severus from Slytherin and as he absolutely hated Gryffindor-students, he had to act as though he hated his own son. One of Severus' colleagues, Slatero Quirrell, found out about Harry and Severus, and tried to kill Harry. Severus couldn't stand this and began to murmur a counter curse.
Severus had been threatening Quirrell, that if he would tell Harry who his real father was, he would kill him.
"A - as if t - th - that is of an - any u - use then, Severus! The b - boy alr - ready knows th - then!" said Quirrell. Severus sighed.
"You know what I mean, Quirrell. And he suspects me of stealing the stone. I'll tell him when I think he's ready for it."
They didn't notice Draco Malfoy was eavesdropping. Next day Draco went to Severus.
"Sir, is it true you're Potter's father? Oh my. Father already told me that Potter's mother had a twin sister, I suppose she was your girlfriend?" Severus looked as if he could explode of anger any minute now. But he had learned to control his emotions, and told Draco, with a slightly quivering in his normally soft and ice-cold voice, "What makes you think that?"
"Well, I – er – I heard Potter talk abut it with his friends."
"Potter doesn't know," said Severus with a penetrating glare at Malfoy, who tried to avoid those eyes, which didn't succeed. Malfoy tried hard to look not guilty, but knew that would be no use toward Severus.
"You've been bugging me, haven't you Draco?" Malfoy murmured something under his breath.
"Come again?"
"You and Professor Quirrell were talking very loud sir. I couldn't help overhearing it."
"Have you told anyone else?" snapped Snape at Malfoy.
"No sir, I first wanted to know if it was true."
"Good," Severus turned away from Malfoy, who was too afraid to move a muscle. Severus thought bout what he could do, then it came to him very clearly: use a Memory Charm. He quietly took his wand, made sure Malfoy didn't notice, and walked around Malfoy, until he was standing behind him. He pointed his wand at Malfoy and murmured under his breath "Obliviate". Malfoy's eyes went blank for a few moments, then he yelled: "What have you done!" Severus smirked.
"Nothing, my dear Draco."
"Sir, why am I here?"
"That's what I was about to ask you."
"I am here to talk with you about. about. I can't remember, sir." "Here, drink this." Severus handed a glass of pumpkin juice to Malfoy, in which he just had dropped a bit of Veritaserum. Malfoy noticed it, but too late.
"Now, Mr Malfoy, you really don't remember why you came over here?" Malfoy thought for a while.
"No sir, I'm sorry, but I really can't remember."
"Good."
"Why?" asked Malfoy, but Severus didn't reply.
"Go back to you Common Room, Draco." Malfoy stood up and walked away, out of Severus' office.
