With a sigh Severus turned back to the pile of papers sitting at his desk. He idly glanced at the clock sitting on his desk and cursed the fact that he still had hours before he could retreat to his bed.

Now don't be mistaken, Severus loved his job as potions master. He hadn't spent over a decade in a job he despised, quite the contrary. The only reason he continued to apply for the position for Defence Against the Dark Arts was because he had to keep up appearances. Deep down he hated the subject that had cruelly taken away his precious Lily.

A soft gasp of pain escaped his lips as he remembered the night. Shaking his head to clear away the memories he stared determinedly at the page in front of him only to feel a soft tear trickle down his cheek.

With a loud roar he magically flung his desk across the room and stormed out, only to come face to face with Remus Lupin.

The slightly shorter man was dressed shabbily, and his once kind face was now tormented by scar and lines, making him appear much older than Severus, even though in reality he was slightly younger.

"Dumbledore sent me to inform you of our new headquarters"

"HOW THE HELL DID YOU GET IN HERE?"

Incurring the wrath of a furious Severus Snape had brought many Slytherins' to tears however Remus merely blinked and stared calmly at Severus. Holding out a sheet of parchment he stares levelly into the younger man's cold black eyes until the parchment was pulled from his fingers.

The black eyes quickly raked over the parchment before setting it alight with a quick spell.

"I suppose you are living there as well?" questioned Severus, all traces of the earlier tears gone. Remus nodded curtly.

"Dumbledore said to come straight away. We have a few issues to discuss before the Weasley's move in." The trademark sneer flitted across the man's face before summoning his coat.

"You didn't answer my question"

"I'm a Marauder. First rule was to never reveal how you did something to anyone." A hint of a smirk danced across Remus's lips as he walked out of the house. With a loud crack both men apparated to the address that had been on the paper. Pushing open the heavy black door, Remus gestured for Severus to enter.

Severus stepped inside and Remus pulled the door shut and walked silently down a corridor and turned. Inhaling the dusty, but familiar smell of the Black house Severus followed him, but instead of turning into the room as Remus had, he ventured up the ancient stairs. Quickly, he made his way to a door which he new he would never forget. His hand starched to the door handle as the door was flung open from the inside. A pair of stormy grey eyes met his own black ones and for the first time, since the night in the hospital wing days ago, they dance with happiness.

"Next time you even think of coming up here, remember why I stopped you in the first place."

Sirius coldly brushed passed Severus and swiftly disappeared into the darkness of the house. A cold feeling of desperation spread through Severus's chest. A feeling he had longed never to feel again. Yet here he stood, in the doorway of the man who had shattered his fragile heart into millions of pieces many years before, only to do the same with a few quick words. Severus closed his eyes and breathed deeply to regain his composure. Once calm he opened his eyes and felt the familiar emotionless make slide back on as he swept back down the stairs, ready to pretend he hated Sirius and all the while desperately wishing that Sirius was pretending as well.

A.N.

So this was an idea I had been throwing around for awhile, the real reason that Sirius and Severus hated each other. Also I love Siri and Sev to death and wanted to do a story with both of them in it. For those of you who didn't pick up on it this story will take place in Harry's 5th year and will try and stick to the book as much as possible but no promises. And I may not kill Siri at the end……..just depends on what you guys think. So please Review!!!
