Sirius felt as if he had been waiting for this day for forever. He knew, in a way, he was lucky even to be having this day. He was grateful for it, though. He knew he had been given a lot of second chances during the war, and now that it was finally over, he had no intention of wasting any of them. He had always assumed that Remus would be with him when he went to see James again. However, even though things were officially over, there was still plenty of clean-up work to be done. Remus was still stuck in France, and Sirius, having been released from Mungo's in the morning, had decided he wanted to see James in the afternoon.
He'd made it through most of the final battle -- and after that, he didn't think there was any doubt about which side he'd been on. That was certainly how Bellatrix had viewed it when she had come after him. She'd Crucioed him twice before a group of Aurors had managed to arrest her. It rankled him that she'd managed to survive, but it was fine he told himself. It was fine as long as everyone he cared about was safe now.
Despite everything, he was nervous. This was the first time he'd seen James were there wasn't case for secrecy. There wasn't any pretense, or any Order business. It was back to just being the two of them -- and they hadn't been the two of them in years now. He knocked on the Potters' front door, shifting around on the stoop, a package for Harry tucked under one arm.
