Chapter One:


Xander has seen a lot of strange things in his life, but a big black dog falling out of portal wasn't one of them. The dog was hurt and he had to help he had the gut feeling that this wasn't a normal dog. Xander learned to always trust his gut feelings.

"It's okay boy I just want to help." Xander told the growling animal as he got closer. He held out his hand smiling. "It's okay you can trust me."

The dog limped closer sniffing his hand then gave it a small lick. Xander slowly got closer and checked the dog to see wasn't that hurt. "You just need some food and rest boy. You can come home with me." He picked the animal up for such a big dog he didn't seem to weigh much.

Sirius remembered going to the Ministry to save Harry only to fall into The Veil thinks to his insane cousin. Now here he was not having any idea of where he was, but the place gave him a bad feeling. There was evil magic around here. He would stay as Padfoot until he learned where he was and how to get back home. By the accent of the boy he was in America somewhere.

"My dad is suppose to be over so I hope he doesn't mind about you." Xander was excited since he hadn't seen his real father in over three months because of the mess in the Wizardry World. Xander was sent to the Hellmouth to live with his squib aunt and her muggle husband. The only person who knew truth about Xander was Willow. "My dad doesn't like dogs much can't really blame him though. I really don't know the whole story only that he hates big black dogs. And that's what you are a big black dog. Oh will I can handle my dad and I'm sure you both will get along just fine."

Padfoot was wondering when the boy was going to shut up. It wasn't really talking more like babbling. The boy smelled nice though and he reminded him somewhat of himself. Bloody hell the boy could even pass as a Black.

"Here we are." Xander opened the door to his apartment and found his father sitting on the couch. He knew something had to have went wrong by the look on his father's face. "Hey dad everything alright?"

Severus Snape looked up at his son and felt his eyes widen when he saw the dog in Alexander's arms. "Black."

"Huh, oh yeah the dog." Xander thought his father meant the dog. "He fell from a portal. It was so weird."

"No, that is no dog." Severus stood up and grabbed the dog from his son placing him on the floor. "Everyone believes you to be dead, Black."

Xander watched as the dog turned into a human man. This guy was from the Wizardry World and his dad knew him. "What's going on?"

"Since when did you have a son, Snape?" Sirius asked after he got over his surprise at seeing the Slytherin and learning his enemy had a son. "And where are we?"

"Sunnydale, California the home of the Hellmouth." Severus crossed his arms over his chest a smirk on his face. "Surely you know how children are born, Black."

No one in the Order knew Snape had a child or was even married. Something was going on and Sirius planned to find out. By Alexander's age Severus was still a student in Hogwarts when he was born. Surely the Headmaster knew. "I want to know why no one knows about your son."

Severus glared at the Gryffindor knowing that if he wasn't careful then Black would learn his secret and he couldn't let that happen. "That really isn't none of your business."

"Hey guys did you forget about me?" Xander was getting tired of them talking about him like he wasn't there. "Can you tell me what's going on dad?"

Severus looked at his son and sighed. "Alexander this is Sirius Black, he is a member of the Order and Harry Potter's godfather."

"Sirius Black." Xander knew all about Sirius Black, but it would seem his dad didn't want Black to know their secret. "Nice to meet you."

"Who's your mother kid?" Sirius just had to know the thought of Snape having a kid bothered him.

"That is none of your business." Severus wasn't about to let Sirius Black know his secret one that he has kept for so long. He was sure Alexander wouldn't say anything either. "I'll contact Dumbledore to let him know you are alive. Potter is upset over your so called death."

Sirius cursed himself having forgotten his godson and knew he needed to see Harry right away, but this wasn't over. There was something bothering him about Alexander, Snape's son and he was going to find out. "Fire call Dumbledore, I need to see Harry."

Xander went over to a wall and placed his hand on it watching as it turned into a fireplace. He threw in the floo powder and called on Dumbledore the old man's head appearing in the fire.

"Ah, Alexander is something wrong?" Dumbledore asked with worry in his voice.

"Nah, dad wanted me to tell you Black is alive and well." Xander stood out of the way so the Headmaster of Hogwarts could see Sirius. "He fell from a portal here in Sunnydale. I brought him home and dad told us to call you."

Albus was relieved when he saw Sirius alive glaring at Severus. It would seem he found out about Alexander and wanted to know why Severus kept his son a secret. "Then come home Sirius, Harry needs you right now."

"This isn't over." Sirius snarled at Snape and stepped into the flames. Xander turned to face his father.

"It's only a matter of time when Black learns he's your other father." Severus sighed, sitting down. "Then all hell will break lose."
