Oliver's sudden sternness broke Al from his thoughts. The middle Potter child never wanted to hurt anyone, especially people he loved, but now an innocent slip might have done just that. He couldn't let Oliver live with a lie for him though. It could hurt Oliver and Percy's friendship, which Al didn't want. "No. It is okay. I made a mistake, but...but you shouldn't have to keep a secret. It will come out one way and...I'll be okay. I'll tell him I am sorry." He would too, even if he wasn't really talking to most of his family.
