A/N - Still don't own Sirius or Remus. JKR can keep Harry. I decided to expand just a bit more. This chapter may let you know why I try and stop after so many words. As fun as it is to slide down hill, it kind of loses its appeal once you reach a certain age and/or health problems.
The Runaway Reunion
Previously
Tonks was explaining what happened, Remus had accidently infected her with lycanthropy a few months before and because of their enhanced physiology they weren't dead just near death, when a familiar voice shouted out her name.
Slowly turning, she sees Sirius and loses all colour from her face. No, it can't be true, he can't be alive. She saw him dead, but then she also saw Remus and Tonks dead. Oh Merlin, she has denied him his children for 11 years. Seeing both Remus and Harry with Sirius she does what any woman seeing the love of her life come back from the dead would do, she fainted.
Now
When Hermione fainted, her children came rushing over yelling what did they do to their mum. Carina grabbed her mother and cradled her in her arms while Siri and Ori stood in front of her, backs straight, shoulders back and hands fisted ready to fight anyone trying to hurt their mum.
Sirius, seeing the boys looking like miniatures of himself at that age blanches. He hadn't thought about why she was on Platform 9 ¾. He a father, and not just of one child but three.
Siri, seeing Sirius asks who he was, and why he looks like a dead man, his father.
Sirius tells him he is his father and that he didn't die that night. He asks his children's permission to go to Hermione. Nodding to him, he picks up Hermione bridal style and cradles her to his chest. He is quietly begging her to wake up.
Meanwhile, Remus had conjured up a wet rag and handed it to Sirius. Wiping her face, Sirius is elated to see her finally coming around.
Awake once more, Hermione reaches up and softly touches Sirius' face and asks is it really him, is he alive? Tears streaming down her face, she begs his forgiveness. That if she knew he was alive that she would have never kept his children from him.
He tells her there is nothing to forgive. He too would have disappeared if she had been the one to die. How he always had hoped to find her again as he knew she wasn't dead or hurt. For what she had never realised as a muggleborn witch was not brought up with this knowledge, that when they bonded during their first encounter, that also meant that they were married.
Sirius and Hermione spent the next ½ hour speaking. They decided that he needed time to get to know his children so instead of having them take the Express; they spent the next 7 hours together and then apparating to Hogsmeade.
Remus apparated to the Leaky Cauldron and then floo called Headmistress Minerva McGonagall, asking to be allowed to come through.
When he stepped into the room, he found Severus Snape there. He turns to McGonagall and explains that three of her new 1st years will meet the train at the Hogsmeade station when it arrives. Their mother and father kept them with them for the length of the train ride.
"And why exactly is that Mr Lupin?" sneers Severus.
"Well... the triplets just met their father and them, along with their mother want to get re/acquainted," Remus tells her while trying not to smirk.
"Just who are the father and mother?" Minerva asks.
"The mother is someone who has been missing these last 12 years, Hermione Granger." Minerva gasps and falls back into her chair while Severus just sneers. Dreading the answer as she suspects she knows, Minerva asks who's the father.
"Your all time favourite student, my fellow Marauder, Sirius Black," Remus chortles, holding back the belly laugh he wants so badly to let loose.
"Son of a Bitch!" shouts Severus. He thinks it will be hell on earth the next 7 years.
