"Sirius! Please get down here and open this bloody door!" Albus Dumbledore bellowed in frustration after close to 15 minutes pounding on the door of Sirius's private quarters. Sirius groaned and rolled over. Slowly, he rolled out of bed and descended the steps towards the loud banging noise. His massive headache was proof that he probably shouldn't have downed four bottles of firewhiskey the night before.

When he finally got to the door, he flung it open... To find Albus Dumbledore holding a sleeping child that looked no older that 7.

"What, Albus!? What the bloody hell do you want?" Sirius demanded, annoyed at Dumbledore's unannounced arrival.

Dumbledore smiled, his eyes twinkling. "Well, Sirius, there has been an accident at school. Someone was deaged during potions class, and I'd like you to help."

Sirius's heart warmed. After Harry's disappearance after a rescue mission, he had been quite lonely. "Of course, Albus, I would love to help. But maybe-" here he groaned- "a hangover potion first?" Dumbledore smiled, and handed him the turquoise liquid.

After downing the foul tasting potion, Sirius turned his attention back to Dumbledore.

"Albus, what did you say his name was, again?"

"Well, Sirius..." Albus' reply was cut off as the child shifted in his arms and rubbed his eyes. The small boy turned towards Sirius, and the man's face darkened.

"Albus... What happened to him?"

Dumbledore waved him off. He put the boy in the ground, and knelt before him.

"Severus," he spoke softly, barely above a whisper. "Will you say hello to Mr. Sirius? He's going to take care of you for a little while."

The boy- Severus- looked up at Sirius and beamed. "Hello, Mr. Black!" He said, and something clicked in Sirius's mind.

"No."

"Sirius-"

"No fucking way, Albus! This is Snivellous? Why me?" Sirius demanded.

"Sirius, who else would look after him?"

Sirius growled. "Get out."

"Sirius, I have to leave him with y-"

"I SAID GET OUT!" Sirius bellowed.

Dumbledore held up his hands in a peaceful gesture, apparating away.

Sirius huffed in frustration. Here he was, in charge of a young Snivellous. Why did this happen to him? His school rival, who belittled Harry, made his life hell in potions, the reason Harry was missing...

Harry Potter had gone MIA searching for Severus Snape after Voldemort's defeat. Harry, his godson, spent three years looking for the git, and here he was!

Severus looked up at Sirius. "Excuse me? Mr. Black?"

"What." Sirius's voice was dangerously low.

"May I have something to eat? I'm hungry."

"Why do you think I would let you eat my food? Off my table? After what you've done!"

Severus's face wrinkled in confusion. "What do you mean? What did I do?"

Sirius appeared to have been punched in the gut. He didn't have his memories... Maybe, once he aged back again, he wouldn't have the deaged memories... That meant Snivelly wouldn't even thank him for all the work he did!

It just wasn't fair.
