I'm sorry for starting the argument at the Burrow, but I am not sorry that it had broken out. Somebody had to oppose their relationship. I don't think it's good either for Jamie or Sirius. Yes, even him. I remember his adult version and I can't think that he'd be happy with his younger version. I'm perfectly willing to apologise to you, but I won't be apologising over doing something I felt, then and still, was right.
I'm also sorry that the argument that broke out reminded you of Percy and Fred, or Jamie's and Dom's recent brushes with death, but that wasn't and isn't the subject of the argument.
