“Get out of here,” Potter snarled, actually pulling his wand. He seemed to get touchier and touchier as the years went on. “You have absolutely no right to be here, O’Bailey.”

“Who says that you do, Potter?” she sneered at him, restraining herself from drawing her own wand just yet. “This is the House of Black, righ’?” she said, pointing at the huge crest behind them that matched her bracelet.

“Sirius,” Harry began in warning voice. “I realize she’s your daughter and all, but she’s also a Slytherin. I know that she pals around with Malfoy and a bunch of other Death Eaters’ kids. Is it really a good idea to tell her about the Order?”

“I could just as easily say that you’re an unpopular Gryffindork, unhappy that he didn’t get his first pick for the Yule Ball, just like Peter Pettigrew,” Bailey sneered.
