Sirius I never understood why you act so guilty like why couldn't you just say "Nah I'm just here to kill the rat" instead of "only one will die tonight". I just think people haven't completely grasped the concept that Sirius Black is the biggest drama queen of all time. SO TRUE JUST READ ORDER OF THE PHOENIX (the film doesn't touch on it at all)
Um... kind of already a thing... remember in the fourth HP book, the prefects bathroom with the crazy bath water taps?? Like, they make bubbles and different perfumes and colors and lots of cool stuff like that... so yeah. Kind of a thing already.
