Sirius nervously chewed on his bottom lip, his foot tapping out a feverish rhythm. He was watching you, waiting for you to finish laughing with your friends before he could fish you out and interrogate you. Well, he wouldn't call it that, but you insisted.

The situation was... a bit dire. Sirius had left his family house this summer. It was a good thing, really. He and James were now like actual brothers. But Sirius already had a brother. Regulus left behind at the manor. Sirius hated that he couldn't take Reggie with him. So he got inventive.

Tracking you down as one of Regulus' closest friends wasn't easy, but still doable. The Marauder's map was of great help in his quest.

After that he, of course, needed to persuade you to tell him how Regulus was doing. Cigarette bribes worked wonders. Sirius didn't like you. You were everything he despised: from Slytherin, pureblood, good at school, close with Regulus. But he didn't really have a choice now, did he?

So every two weeks like clockwork he would seek you out and ask how Regulus was. Well, maybe for the first ten times that's why he actually met with you. The last five... he wasn't sure. He was starting to feel something. Something he didn't like to think about or admit to himself. After all, what was wrong with him? Having a crush on his brother's friend? Come on!

"So how is he?" Sirius said, feigning indifference. He was trying not to look at you too much, afraid he might say something he'll regret. An empty classroom where you two usually met was especially quiet today.
