A/N: Thanks to ChaoticSisters for writing most of this chapter. She's so full of great ideas, she should probably get back to her own story.

Ahh! Look at me, finally committing to an update schedule. Let's see if I actually stick to it.

If you enjoy reading my stories, my profile has a poll on it! It's still open, and you can cast a vote for my next writing project.

Thank you and enjoy.

It had been two weeks since Petunia, Dudley, and Harry had moved in with Sirius and Remus. Things had settled down, and Petunia was glad that she had made the choice to leave Vernon. She had filed for divorce, and was almost certain to have full custody of her son and nephew. Harry and Dudley were playing together on the floor, and Petunia was watching them. Remus was in the kitchen, cleaning up after breakfast.

Sirius apperated into the living room, the boys jumped slightly, before bursting into laughter. "Lets go to Diagon Alley!" Sirius said with a grin.

Petunia looked up and smiled. "I haven't been since I was fifteen. The boys would love it!" She lifted Harry up, while Sirius got Dudley.

"Remus! Do you want to come?" Sirius called to his friend.

"No thanks! I'm going to work on my room!" Remus replied, continuing his work.

The four who were going climbed into the fireplace, grabbed flu powder, and with a cry of "Diagon Alley!" vanished in the green flames.

When they stepped into the light, they found a beautiful scene before them. Magical things were everywhere. They headed straight to a shop that sold things for wizarding children. Dudley and Harry stares wide eyed at the many wonders of the magical world. Harry was transfixed by the glowing image of a stag that ran in circles around a mobile. Sirius laughed, and purchased the mobile, and chose a similar one for Dudley, though instead of a stag, Dudley's had a rabbit.

After the first shop, they went to get ice cream at Florean Fortescue's, to the delight of Harry and Dudley. Since they were so young, they shared a small dish of ice cream.

"I do wish I'd come here with Lily more." Petunia said.

"Well, you can come anytime you want now." Sirius replied.

"No, it's not just that. I wish I'd spent more time with her." Petunia mused. "I wish I hadn't been so mean to her just because I was jealous. I wish I'd been at her wedding. The last thing I did for her was to send her an ugly vase for Christmas. That was the last contact I had with her, and all I said in the note was 'merry Christmas.' If I could do this all over again, I would do it all differently."

Sirius put down his spoon and looked at her. "You can't do any of that, though. We all wish we'd done something differently. But we can't, so we have to accept what happened and move on." He paused, looking down at the charmed pendant Petunia was wearing. "You kept the charm the ministry gave you. No matter what you said, you always wanted to be part of this world. I'm surprised it still works after all this time. And even more surprised that you knew you'd need it to find my house."

Petunia shrugged. "Everything magic is hidden from the non-magical community. Why not the houses too? Your neighbors would be terrified if they could see in through your windows."

Sirius laughed. "Yes, I suppose they would."

The next day, Petunia and Sirius were sitting in the kitchen, baking cookies for the boys, when Harry came running into the room. "Paffoot! Paffoot! Duddy did a magic!" he shouted in exitment, Dudley came into the room after harry, looking excited and rather pleased with himself. "Duddy thew his toy an it floaded up to da roof!"

Sirius broke into a grin. "Thats Great! Good job Dudley!"

Petunia looked pale.

"Whats wrong?" Sirius asked her, confused.

"It's good that I got out when i did." She whispered. "Vernon would have killed him" Sirius shivered slightly.

Petunia managed a smile. "Thats wonderful sweetie!" She said to her son. Harry was grinning like a child on christmas.

Sirius laughed. "A witch for a sister and a wizard for a son? You must have some magical ancestry you don't know about. Probably a squib married into the family at some point." Sirius became serious. "But really, magic at his age? Almost unheard of. Earlier magic is considered indicative of great magical ability, though there are never guarantees. Magic usually shows first at five to seven years. Three to five is less common, but not unheard of. But at one year? I can count all the cases of that in the last century on one hand."

"So his magic is strong?" Petunia asked.

"It would appear so, but as I said, there are no guarantees. Sirius replied. "Oh, no."

"What? What's wrong."

"Hopefully nothing yet, but Harry and Dudley seem to have wandered off while we discussed magical ability."

"Oh, no."
