A/N: Hello again. Another day, another chapter update. Hope you enjoy!

One Small Change

(Sirius POV)

As I left Dumbledore's office I looked back down at the infant in my arms. He was asleep, which drew a broad grin on my face. If he was anything like his dad he'll be painting masterpieces before he goes to Hogwarts, as David described that Dean's mother, unlike Sam, was a pretty fair painter and sculptor herself, which is what drew David to her. This was after Sam had left him, thankfully.

Now is not the time to reminisce however. I need to talk to Marlene, Prongs and Lily. With that in mind I walked out of the school boundaries and apparated to the apartment me and Marlene share in London. Dean looked in moderate discomfort, but he didn't cry thankfully. Looking around, Marlene wasn't there.

I went into one of the spare rooms we hadn't decided to do with yet. Luckily it had a few useless things lying around which I transfigured into a cot, some blankets and some toys for him to play with. As I placed him in the cot and gave him a rattle, I heard the front door open, so I grabbed my wand and sneaked out, pointing my wand at Marlene's face, as she did the same with me.

"First time we had sex?" I quickly asked.

"After our second date, in your dorm room. Nobody else was there. First time I told you I loved you?"

I knew this was a trick question, most wouldn't know the answer, "In fourth year, even though we weren't dating," I replied, smirking.

She grinned and gave me a long kiss, which I gladly accepted, before we broke apart and my face became, pardon the pun, serious.

Suddenly she frowned at my face and I knew that she knew that something was wrong. "What's happened honey?"

"It's a long story, maybe you should get a cup of tea. I'm still wrapping my head around the whole thing as well," I told her, sitting down on the couch. "I need you to sit down and listen without any interruptions honey. Can you do that?" When she nodded I started at the beginning, "It all started when I went to meet my brother," I began, and her eyes filled with joy, she was the one who convinced me to go, "he had some unsettling news to tell me. I can't tell you the full details but he's on our side now.

"I then went to see Dumbledore with Reg in tow, but we went via Andy's home and in short, she and Dora know he's on our side now. When we arrived at Dumbledore's office he told Dumbledore his story, while I received a patronus from David," I sighed, knowing that this was the hard part of it all, "telling me to come to his place as his house was under attack from Death Eaters.

"When I got there it was bad. I stunned the Death Eater he was fighting and tied him up, but David was hit by Snape's spell he used on you in 6th year, and even if I knew the counter curse it was too late. We talked for a bit, and I found out a few things. David's girlfriend was dead, and he left his son to us. Marlene, this next bit cannot go beyond this room, do you understand?"

"What is it Sirius? You know you can tell me anything," she asked.

I nodded and took in a deep breath, "Wormtail is the traitor. This was apparently his initiation and David managed to unmask him before he got away. Nobody except me, you, Dumbledore, my brother and Moody knows about this, and only 3 other people are going to know. I think you can guess who they are," I told her quietly.

Marlene nodded, knowing that we were planning on telling Lily, Prongs and Moony. I suddenly smiled, taking her free hand and standing up with her. "Want to go and meet our new son?" I asked her, guiding her down the hall, and a worried look came on her face.

"Why not Kingsley? I understand not giving him to Sam, but why not his little brother?" she asked, and again I was surprised about how perceptive my soon to be wife was.

"Because he's married to the job. He wouldn't have the time or the money. We do, however, since your parents are giving us a huge dowry and I got 15% of the Potter's fortune when they died." I explained.

She nodded and then her lips split into a huge smile when she saw Dean in the nursery, cooing at him, "He is so precious. Hello honey, I'm your new mum, Marlene. What's his name, Sirius?" she turned to me.

Smiling at how good she was with him already, I quickly said, "Dean. His name is Dean Andrew Black. I think we should change his name to ours in November when we get married, don't you agree?"

She smiled and nodded, knowing that it was easier to call him Black if he was in our custody rather than Shacklebolt as we were planning on having kids fairly quickly.

She then looked at me again and her face said that she also had to tell me something fairly important. "Well Dean's going to be a big brother pretty soon so it's good that we'll have some practice with him," she mildly commented as I just stared at her, before a grin spread on my face.

"You're pregnant?" I asked, as she smiled euphorically and nodded, "I'm going to be a dad..."

"You're already one silly," my fiance teased, pecking my lips, "little Dean over here is all but your son. But yes, this one will be your flesh and blood."

I smiled, knowing that she was dead right, as usual, taking Dean and placing him in the cot, before taking Marlene's hand and guiding her towards the kitchen and thanking her in the best way I know how.

Get your mind out of the gutter, I was cooking her dinner! After all, she was eating for two, isn't she?

After that? Oh yeah, we did it 5 times after, but that's beside the point.

A/N2: Hello again, yes I'm back. What did you think? Please drop a review and tell me. I'm sorry that it's another short chapter, but we all must make sacrifices, no? I think I'll go into Pokemon mode again soon for those following my other multi-chap! Then again, you never know with me, do you?
