Excluding Remus, the day had actually gone well for the most part, even considering the hangover. James had been relatively prompt with the potion, thank Merlin, and Sirius had also showered, changed into new clothes, and left without telling James where he was going. Regulus clearly hadn't been a good topic with Remus, and he wasn't about to get into it with James as well, if that were what was going to happen. And he didn't want to talk about Regulus anyway.
But it had gone well - amazingly well. And all of his insecurities, for the moment, had been washed away. Regulus was his little brother, and Sirius loved him. And it was good. But the journals hadn't helped in the morning, and it wasn't like Sirius had any idea when Regulus was going to be back. Stalking the journals was just going to ruin any bit of good mood he got, so instead he kept it closed the rest of the day. There had even been some good dueling thrown in.
But there was always work on his bike. And that was where he had been for the last few hours. And time flew by like nothing else. The rest of the world was gone as he engaged himself both magically and physically. He was down to jeans and a dirty wifebeater while he worked, and his arms were also dirty with sweat and grease. He hadn't expected to hear anyone's voice.
Remus. Sirius didn't look up right away, with half of his lower arm intricately working on the bike. "I'm glad you know how to read," Sirius replied as he twisted the part in. Once it was secured, he glanced over his shoulder for a moment. Remus almost looked like a fucking statue, for all the emotion showing.
