Well here is the new chapter. Is it just me or do they all seem to be getting shorter? I really should start making them slightly longer. Oh well, maybe next time but for now, as Hermione would say, happy reading!

Disclaimer: I, unfortunatly, do not own Harry Potter nor anything associated with the Harry Potter series or Warner Bros. productions and can only take credit for what my own mind has come up with.

Sirius stared horrified at the young wizard infront of him, his face a portrayal of the terror and anger the young boy held for what he just witnessed his Godfather doing.

"Harry?" Sirius tried to get the boy to speak to him, raising one hand in an attempt to comfort the confused boy when Harry jerked away from his touch and made to turned on his heel to get away from his Godfather.

But Sirius was quicker and he reached out, grabbing the arm of the boy-who-lived before he was able to run away, but the instant his fingers closed around the scrawy arm, Harry began jerking his arm, fighting against the man who had hold of him.

"Get off!" He struggled against the grip on his arm, "GET OFF ME!"

The sound of his Godson so angry shocked Sirius into loosening his grip so that Harry was able to wrench himself free and take a few steps away from the long haired man.

Sirius blinked and sighed shakily, "Harry...you have to let me explain...I..."

"I know what you did to him!" Harry glared, anger and betrayal written clearly across his young face, making him look more furious then Sirius had ever seen him.

The older man sputtered, eyes wide with confusion and shock, "W...what do you mean?"

The teens face twisted, "I know what you did to him...when you were at school..."

"H...how?"

"I saw his memories. In the pensieve he keeps in his office. I've been sneaking back since last month to see what else was there."

Saying it outloud made Harry feel even more guilty for sneaking around, but he pushed those feelings to the back of his mind as he glared down the one man he'd looked to as a parents since his third year.

Sirius dropped his head and frowned heavily, before sighing and moving towards the fireplace. He took a handful of floo powder from the pouch on the mantle piece and threw it into the grate, sticking only his head into the grate he said clearly, "Hogwarts School of Witchcraft and Wizardry, Professor Severus Snape's Private Quarters" and with a blast of eeiry green flames, there was suddenly an agitated, angry voice sounding from inside the fire.

"What do you want Black? Haven't you done enough damage to me for tonight?"

But the biting tone was cut off by the sound of Sirius' defeated plea, "Severus, I need you, it's important..." and the sentence had barley been finished when the form of Professor Severus Snape appeared inside the fire, gracefully stepping out of the grate with a confused and tiered expression plastered across his face, which Harry thought made him look about 10 times older then he actually knew he was.

"What's so important that you need me?" the teacher asked, emphasising the word Sirius had used. But his sneer fell dead on his face when he caught sight of Sirius' scared and guilty face, compared to the confusion, anger and pain on Harry's.

Severus looked between the two, contemplating who had done what to cause such frayed tension between the two who obviously loved each other, and who were now standing on opposite ends of the room both looking like they done something wrong.

The bottomless black eyes caught watery blue as his gaze rested on Sirius, "What have you done now?"

Sirius body shook as he took in a breath, "Harry saw us...just before...he knows Severus...he knows everything."

Snape's usual unpenetrable, blank mask died instantly as his face twisted into a look of pure horrorified anger, "What do you mean he knows everything?" his tone was biting and filled with uncertainty and fear. Harry had to blink and look closely at the man to make sure it was still him.

Sirius shook his head, "He found your pensieve, saw your memories."

Snape's furious glare rested on the teenager, rooting him to the spot as the terrifying wizard bore down on him, grabbing the front of his shirt and sneering, "How dare you go through my personal things! You would've had to break into my office to find that pensieve! HOW DARE YOU!"

It was Sirius who had to jump into action, prying Snape's long fingers from Harry's now creased shirt and gently pushing the fuming man away.

"Don't take this out on him Sev, he's had enough of a shock alread."

"A shock!" Harry gasped out, speaking for the first time since Snape arrived, casuing him to feel even more guilt for betraying the mans privacy, "A SHOCK! I saw you! I saw what you did to him!" he glared angrily at Sirius, gesturing to Snape who stood slightly uneasy, "I've been replaying it for almost a month! When I saw you..." But his voice died away as the images of the most horrific memory surfaced in his mind, causing him to bite his tongue to stop himself from being sick.

Sirius looked terrified, guilty like a man on the last second of being convicted, and he turned his pleading eyes to the other man, beginning him to do or say something that would help.

Severus' face softened at the look Sirius gave him, and he turned unusually kind eyes on his student. "Harry" The sound of his first name coming from that voice was enough to shock Harry into looking up, staring intently at the man hovering a few feet away from him, "I understand your confusion about what you have seen. You had no right to go through my private memories but now that you have you must know that what was in that pensieve was barely half of the story."

Harry's wide eyes glazed over for a few moments as he took in his professors words. He watched with curiosity as Snape turned to Sirius and said, "Show him."

Sirius shook his head but one meaningful look from his ex-lover forced his hand and Sirius unbuttoned the bottom over his shirt, moving the edge up to reavel a long, deep gnash that ran jagged and headled over from Sirius' left nipple, all the way down his left side and came to an end on his lower back, mere inches from the base of his spine.

Harry gasped, tears springing to his eyes at the injury his Godfather hid. Sirius fixed his shirt again and breathed heavily.

"What you saw in those memories," Snape continued, "Was the way Black treated me all those years ago." He glanced at Sirius and Harry barely caught the flash of pain in his eyes before it was gone again, "What you didn't see was the way I treat him."

Harry gasped, looking again and Sirius' now covered side and then back to Snape who nodded, strands of black hair falling into his black eyes and covering the purple bruise on his face, "Yes Harry, I gave him that scar. It's not the only injury he recieved from me, but it is the worst and it is the one I'm the most ashamed of."

With rapt fascination, Harry watched as Sirius placed a gentle hand on Snape's arm, sqeezing for a few seconds and then moving it away, as if that one gesture gave him all the comfort in the world, Snape's whole body visibly relaxed.

"Harry," Sirius spoke again, his voice wavering as he took a step towards his Godson but he was pleased that this time the young wizard didn't step away. "I know you must be confused about what you know, and I'm willing to explain everything as best I can, but the urm...relationship...Severus and I have, well, it still confuses me sometimes and I don't think either of us have ever truly come to understand it."

Harry shook his head, green eyes swimming with uncertainty as he ran one hand through his messy black hair and pushed his glasses further up his nose. The something else suddenly hit him, "So what about tonight?" Harry looked between the two men, "You attacked him, and then you didn't even defend yourself. You just agreed with what he said and left."

Severus sighed and looked at Sirius, "Like Sirius said, even we do not understand ourselves sometimes. And he obviously has much less self control then me, Sirius is often prone to portraying his emotions in a violent and angry way instead of having the human decency to calm himself. It's a common trait of a dog."

Sirius' eyes slit into a glare at Snape, "Don't start with me now Snape, I'm not in the mood for an argument with you."

Snape merely shrugged and returned his gaze to Harry, "Look Potter. The one thing you have to understand, though believe me it does still pain me to admit it, is that Sirius is not a bad person. In fact he is an abnormally good person. Yes, he has done bad things in the past and believe me, no one knows more then me how much he regrets them, but he is not the only person to have those faults and he would never do anything to bring harm to you or anyone else he loves. You can trust him with that."

The unmistakable tone full of certainty and conviction at his own words floated around Harry's ears, but something else hit him just as he saw Snape turn to leave.

"But he loves you."

The other man stopped in his tracks. Turning smoothly on his heel to look at the teenager, confused. "I saw it, in one of your memories. You were in the Astronomy tower, I think you were going to jump when he stopped you. And he admitted he loves you..." Harry's words died off when Sirius suddenly slumped to the floor, his expression between sadness and a small smile.

Snape stared intently at the man on the floor for a minute before shaking his head. "One of those things I regret...was not jumping when I had the chance."

And not waiting to see Sirius' head snap up and the ex-Gryffindor jump up from the floor to try and catch him; or seeing Harry's sad frown and shaky gasp, Severus threw his floo powder into the grate and vanished in an explosion of green flames for the second time that night.

A/N: Oh I love ending on cliff hangers, it gives me so much to work with in the next chapter. Hope you enjoyed it and please do keep reviewing, your wonderful reviews make me a very happy little writer.

To be honest I regret revealing Harry's knowledge to Snape and Sirius this early in the story, but once again with this new chapter my plans for this story have changed and Harry, as well as someone else, will begin to play a key role in discovering more about Severus and Sirius' past. Wonder if you guys can guess who it is?
