It didn't occur to me it might be an old DR entry, although that makes sense, it struck me as odd that it had appeared when it did, when there was no explanation for her to be talking about this. She does this when something's happened,. and nothing had.
She was also talking differently, as though she'd been asked a direct question about Hazel, because when BB ask someone about another HM their reaction is always different to the way they normally speak.
Very iffy.
