James was right, they should have known, they'd been close for so many years though, and Remus had been pulling away from them. Sirius still didn't know why, but obviously it hadn't been what any of them had so stupidly thought of their friend. When it had been Peter who had been right there with them, like he was one of them, all the while he'd been preparing to turn on them. "I know, Prongs." He said with a tired sigh, it had been perfect, Sirius had been willing to put himself on the line for his friends, to be the more obvious target while Peter kept their secret safe, but instead he'd given it up maybe even the very night he'd taken up the role of secret keeper.
But Harry survived, that had been the important thing, Harry had survived and he'd put an end to Voldemort that night. Sirius still didn't fully understand it, and even hearing more about it from Jamie hadn't made it all make sense, but he'd answer what questions he could for James as best he could. Peter had been a little too good at getting his way out of sticky situations, who knew the little rat could have produced a curse like that.
"You know what it's like." Sirius said, if it had been as simple as telling Dumbledore what happened he could have had Harry with him, they could have made a go at it. "They didn't want to hear anything I had to say, it didn't matter what I said, how much I shouted, I even begged." He admitted, "They all knew I was the secret keeper," Because that had been the plan, "And Peter left behind a finger, he made it look like I'd killed him too. They didn't waste any time putting me in-" He faltered there, James should know what they'd do to someone like that.
As for Harry? "I don't know about Harry, where they put him, I gave him to Hagrid that night to take to Dumbledore, gave him my bike to make sure they got there safe." He explained, "But after that?" He didn't know, "Jamie would know." He said after a beat, "Things here are .... they're strange, Jamie is here, James Sirius Potter." He told his friend, "He's - He's Harry's son, Prongs. He could tell you more about what happened after, I've talked with him some already."
