Sirius said, "Minnie, speaking of goblins coming tomorrow, I did something that you might become angry at me for. Whilst Harry has hired one group of goblins to render the basilisk tomorrow morning, I hired a different group of goblins, all of them curse-breakers, to go into Hogwarts tomorrow morning, to track down the "DADA Curse,’ and to wipe it out. Don’t worry about how much all this costs—I’m paying the goblins out of my own vault."
