"James, you never cared about me or Remus as much as you cared about Sirius. Never. It was always the two of you, through thick and thin. Sirius who moved in with you. Sirius who was Harry's Godfather. Sirius who would never be questioned. You already cared less about us and we got used to that. Having Lily and Harry just meant that there were two more people who came before us and we learned to adjust to that as well," he said with a shrug. "Okay, Remus adjusted, I resented."
Peter nodded. "Yeah, let's go find that room." The rest needed time, because he knew that one apology wouldn't change anything. James needed the time and Peter knew how important that was.
Hopefully with time, they'll finally get those smarter, mature Marauders they kept talking about.
