"So what, Remus?" he said, perhaps a little harsher than he needed to. "You're not getting it. You're supposed to trust him. You're supposed to confide in him. He didn't trick you, he just couldn't stand being away from you, all right? Give him a break."
Okay, so perhaps James was biased. But Sirius was his brother, and Remus was his friend, and he didn't have a bloody arm and he could barely hold his own son properly, and he wasn't going to let his friends fall apart because of some stupid curse that had addled Remus' brain.
"Sorry I snapped. Just. Remus, we're all lucky to be alive. He was so ruddy worried, you can't just... you can't just cut him out," James said, and now there was a pleading tinge to his voice. Maybe he needed his friends to be okay. He needed some semblance of stability in his life right now, and that was what Remus and Sirius and Peter had always been for him.
