Youre Sirius Black's twin sister , whos somehow worse than him. An absolute trainwreck, peacock animagus, detentions, smoking, drinking, fighting, total whoring around, always getting into trouble with your other Gryffindor friends. James Potter sees right through it, and hes utterly captivated, but built up by lots of tension and contempt at first, but hes a good charmer, and charm he does.
