Peter frowned at everything that was being said, the words that were tossed - or lashed - around the room. He sat quietly through much of it, especially as Sirius's voice began to rise to something more angry, sharper than before. He bit his lip and looked after him as he left, wondering if he should follow. Feeling like he probably should.
"That was pretty low," he said. "Using his family like that. You guys know Sirius has always been loyal to us. Since the beginning." To suggest that that might have changed because he was amending things with his brother - well, it was no wonder that Sirius was so angry.
"Suggested that his family might get in the way... that's like, the worst thing you could say." To Sirius, who always made such an effort to show that he wasn't like the rest of them! He shook his head.
