A/N: Is anyone else noticing the severe lack of plot in this story? It is really making it difficult to write chapters. This is my first time, in this story, writing Sirius. Hope it turned out well.

Title: Games

Sirius sighed, wondering how Remus had talked him into going to the library to do their holiday work on the first bloody day of the Christmas holiday! Growling, Sirius reminded himself exactly why Remus had talked him into this. After last night, and James and Regulus's first date, Sirius had been stressed as anything. His first reaction to James's recount of the night was to go off and find the bloke who had hurt his brothers and kill him. His next was to realize that James had said he had been kissing Regulus when the guy showed up.

Now Sirius didn't know what to do. He was torn between screaming that Regulus wasn't good enough for James, and screaming that James was corrupting his little brother. He was confused, because he didn't know who to protect, and he didn't know how to do anything.

James had seen the look in Sirius's eyes after the fact that him and Regulus had kissed sunk in, and had screamed at Sirius and then stomped off to bed. James was now avoiding him, and Sirius was frustrated beyond belief.

He knew that Regulus wasn't the monster that he had always assumed, but he still didn't see the side of him that James kept insisting existed. Regulus may not be a monster, but he was still a spoiled prat, and he still treated Sirius with contempt. After all, isn't it supposed to be forgive and forget after an apology? Sirius had apologized for their past, and he had thought Regulus had forgiven him, but it was obvious that the boy still hadn't forgotten. He threw their past into Sirius's face at any opportunity.

He had pointed that out to James last night, and James had yelled at him to grow up. He had said that Sirius was just being overly sensitive. Sirius had hexed him. James had punched him. Sirius guessed that James was still aggravated from the brawl at the pub, because James wouldn't normally hit anybody. James had glared at him and stalked off to bed, telling him that they would talk when Sirius stopped being a prat.

That had stung. It had sounded far too much like Regulus saying that Sirius should come back when he knew Regulus.

"Hullo."

Sirius looked up and sighed. Great. Regulus.

"Afternoon. Heard you had an interesting night," Sirius looked at the seat next to him, silently telling Regulus that he could sit down if he wanted. Sirius may have been angry and annoyed, but he wasn't willing to take it out on Regulus. He would make sure to never do that again.

Regulus sat down, "Interesting isn't quite how I would put it." The younger Black took out his potions book and opened it to a marked page, then took some parchment out and a quill and ink.

"Going to do it again?"

"The date, yes," Regulus smiled to himself, "The fighting, hopefully not."

"Enjoyed it then," it wasn't really a question, so Regulus didn't bother to answer. "James really likes you."

"I really like him," Regulus looked up, meeting Sirius's eyes.

"I know," Sirius sighed again. "It's still really weird. You are my brother, and he is as good as."

"But he's not…not by blood anyway," Regulus smirked, "No incest."

Sirius laughed. "No, no incest." He bit his bottom lip, staring at his book. This was so weird. And it didn't help that the only time Regulus's voice held any emotion when talking with Sirius was when they spoke of James. "Why are you here for Christmas anyway?"

Regulus shook his head, "Mother and Father…had plans."

Sirius tensed, wondering what the plans were. Probably plans for getting Regulus the Dark Mark. Sirius mentally slapped himself. He had to stop thinking like this. Had to stop automatically jumping to the negative whenever Regulus or their parents were brought up.

"Give you a chance to spend Christmas with James," Sirius nodded, trying not to push it in case Regulus didn't want to spend Christmas with his…what? Boyfriend?

"That would be fun, though I'm not sure whether James has other plans," Regulus started taking notes out of his book.

"It's going to be hard for him this year."

"Why's that," Regulus looked up with cold eyes, and Sirius realized how that sounded.

"I didn't mean…" Sirius bit his lip, "It's just that James's parents died at the start of this year."

Regulus paled. "How?"

Sirius's gaze hardened, "Old age. Peter's dad was killed by Death Eaters this summer, though."

Regulus looked away, "Oh." He sighed, and began packing his things.

"You're leaving?" Sirius growled; trust a Slytherin to run from the truth.

"This isn't exactly a conversation that I wish to continue," Regulus did not look up.

"So change it. Don't just run away!"

"You don't seem to understand," Regulus looked at Sirius. "I could change it, but to what? We don't know each other. We don't have much of anything in common. And you are practically blaming me for something that I had no part in and had no way to control, even if I had known about it."

"I…" Sirius looked away. "Don't go. This is just…hard. It's hard to change the way you've been thinking for years."

"Why should I stay?" Regulus sighed, "This isn't working terribly well."

"I'm sorry. I just…I'm trying," Sirius bit his lip. "James told me to grow up. That I was being a prat." James was safer ground. They could talk about him, kind of.

"You are," Regulus said coldly.

Sirius bit his tongue to stop the reply. He thought for a moment, and then said, "You aren't being too helpful."

"Didn't realize that I was supposed to be making this easy on you," Regulus glared, "I don't know how to, anyway."

"Just…er…you've turned into a brilliant seeker," Sirius looked at the table.

Regulus hesitated, and then whispered, "I learned from the best."

That was the first reference that either had made to a time when they were young and had still gotten along. Sirius remembered how they used to go flying, playing seekers and trying to beat each other at catching a snitch, or playing chaser and keeper, or beaters and sending soft bludgers at each other. They were some of Sirius's best memories from growing up.

"I miss that," Sirius whispered.

"So do I. I miss playing against you with just us. No teams or points or audience. Just for fun."

Sirius looked up again, "Maybe, we could do that sometime this Christmas."

"Seeker and beater, wouldn't be much of a game. I can't really play any other positions well anymore." Regulus looked regretful, and Sirius was glad to realize that the boy wasn't just looking for an excuse to get out of it.

"Maybe a game with James as chaser, me as beater, and Remus as seeker against you and Snape…erm, don't know who else. Peter's gone home for the holidays," Sirius cringed. He hadn't meant to change the subject back.

"Did Evans stay?"

Sirius grinned.
