Hermione had to push the jealousy aside and get back to what was important. She knew they didn't have very much time to actually talk about this.
"Bullstrode I don't trust at all. She was in the Inquisitorial Squad. I don't know anything about Vaisey, but..." Hermione shook her head. "No, it would be too dangerous to have something like that slip out. Most of them should be safe enough, anyway, coming from their blood lines. I know that some of them were outed as muggleborn recently? But I don't know which ones, I haven't had enough time to pay attention.... You could warn them, but not until it's time to leave, so that they don't have time to use it against you. Or I suppose you could just warn all of them right before it happens, they wouldn't be able to stop it then anyway."
