"We'll do it together," James said, and there was a certain aspect of beauty to that. He and Sirius had always done their best work together. He ignored the little voice that pointed out that the Marauders did their best work together, because Marauders included Peter, and he couldn't think of him right now without completely losing his mind. "Of course he did. Self-preservation was always his strongest trait." He closed his eyes, ran a hand through already wild hair. "We should have seen it. I should have seen it."
James did as Sirius asked, looking at his oldest friend and tried to focus on his words. Harry had lived. He'd survived. "How...how did he survive? He's so little." He couldn't think about how Sirius had only mentioned Harry, couldn't think about what that meant for Lily. For the love of his life. If he did think of that, he'd have to imagine life without her and he just wasn't ready for that.
The information about bizarre magic and different worlds and not knowing how the magic here worked registered, but not as deeply as the rest of what Sirius was saying. "Five years? Sirius that's...where's Harry? Why isn't he with you?" Things were starting to fall into place. Things like Sirius' emaciated frame, the lines on his face, the haunted look in his eyes, but he still wasn't ready to put them together to form the big picture.
