Severus had never been a man to lose his cool easily, well not since he was in school, for one needed a heart to be able to be hurt. He had shut his off, well with a few rare exceptions like his beloved godson, after Lily, after his wife betrayed him. His heart was filled with a black hate, for James Potter who stole his wife, and the child born of it. He had told himself he was a spy, his life was touched by evil, and he had no right to inflict that on anyone. If Lily could not stand by him, he could not expect anyone to, except Lucius who he was forced into the mark with, and had spied together. He was meant to be alone, to teach and watch other men's kids grow up, and never to have such pleasure himself, other then helping raise Draco.

Now he learned the child he had hated from birth, who he tormented for his parents' betrayal, was his son. He knew Lily had wanted them reunited sooner, she didn't know Sirius would be in prison, or the war would take so long, or Albus would do this. He trusted the man, his mentor and even like his dad in most ways, he had never questioned why the man made him spy, and not get him a pardon. Nor had he turned his back, when he found out the man lied about the kiss, not sure why at all.

He found Albus with most of the other staff in the staff room, and the old coot had the audacity to smile. "Severus, we were not expecting you back before the fall."

Severus was not even remotely willing to play this game. "I wasn't expecting to be informed I had a son. I guess today is full of surprises for both of us."

Surprise rippled through the room, for while it had not once been uncommon for a teacher to be wed and have kids, Severus was a different matter. Poppy and Filius were the only ones he called friend, and neither had known he even dated; only Albus had known about his wife.

Albus tried to remain calm. "A son Severus? How wonderful for you, when do we get to meet him?"

Severus threw the papers down at him. "Don't try it old man. I know you knew Harry was mine, you manipulative bastard. You knew."

He had known the prophecy, he had come to Albus, and even hating Harry, he had tried to save them. Albus had allowed him to not know he was a dad, and forced him to watch over Harry, all the time knowing the boy was his. Forced to protect Harry, and believing Harry was James', had only built on his resentment.

Filius spoke. "Severus what is going on? I am sure there is a misunderstanding here. Albus would not have kept your son from you."

Severus sneered. "Tell them Albus, how you tricked me into leaving her, how you told her I was dead. Tell them how you swore to her, you'd tell me the truth."

Albus had gone stock white. "Your wife and son were at risk with you. I was protecting them. I always intended you to some day..................."

Severus cut him off. "My son is a grown man. You have stolen my chance to raise my son. How did you convince Sirius, threaten to turn him back in?"

The old man began rambling on and Severus went into his mind, knowing the old man had his defences down, in his anger. He knew Sirius hated him, but he was loyal as man's best friend, and he would have kept his word, unless either he or Harry was threatened. If he had been threatened to be turned in, he may have kept is tongue, intending to tell them when it was safe. But he was shocked when he went into the old coot's mind, and saw him obliviate the memories of Sirius, of Lily telling him. It had been the night Sirius returned from the run, and he had told Albus he would be telling Severus.

He came out of the man's mind. "The mutt even knew Harry deserved to be with me, even my worst enemy in school, and I thought of you as family."

Albus tried to calm him. "Harry was at risk from Voldemort, and he needed to stay where he was. You and Sirius would have just put your son at risk."

Ignoring the room full of people Severus pinned the man to the wall. "I was good enough to protect him from the shadows. You had no right old man, none."

He felt a hand on his arm, and he knew it was Minerva, but for some reason she nor any of the other teachers, were moving much to stop him now. They were all reeling in shock from what they had heard, and since none of them could not deny they would have done the same, they kept back.

Albus sighed in relief when Severus stepped back. "Harry is with his relatives for the summer, because of renegades, but I am sure in the fall..."

Severus took the forms. "In the fall? You are as loopy as the prophet says if you think I'll wait. I have lost seventeen years with my son, not another day."

The man tried on the same story he gave Remus, how Harry was safer where he was, for there were those on the run. Remus was being permitted to take him for a day tomorrow, since he came of age, for his apparition test, and Albus was sure Severus could join. Surely he understood this was for the best.

Albus put a hand on him. "You know I have always seen you as a son, and him as a grandson. I will do all I can in the fall, to help you two become close again."

Severus looked back. "I am taking my son, and if you ever try to come between us, I will make sure you're the one in a black cell. You know I have enough."

There was a lot the old man had done, in the name of the war, which was borderline or even dark. He had never answered for a lot, Lucius and Severus were few who knew, but they believed they owed him their freedom and lives. If the old man even tried to stop him, he would go to the ministry, and Lucius would more than back him up. He had a feeling his brother's contacts might be needed, for Albus would not back off easily, but he never doubted his brother would help, or Remus likely.
