Dylan didn't know what to answer to that. What did you answer to that. "It was nice of you to help with his cauldrons." Well it was. No one could deny that. And the guy had helped save them, he couldn't deny that either.
He didn't miss that Al too had only mentioned James, just like his grandmother, just like it was supposed to be. It didn't help his previous feeling though he pushed it down far beneath the surface, while studying Al.
"I know you mean well," he then said. "But I really wouldn't bother. Snape isn't the friendliest of guys, I doubt he'd think your papers matter. You're just setting yourself up for a hex, and it's not worth it because then Jamie and I will have to hex him right back and nothing good can come of that." He didn't hesitate to include himself in that because Al was Jamie's little brother. Of course he'd protect him in a heartbeat. Not to mention that he wouldn't let Jamie go alone.
