Back at Hogwarts after the holidays, Sirius and Remus test out their new raincloud charm, but a bitter exchange with Snape sets the stage for trouble. In the Great Hall, Remus—still stung by Snape’s insults—casts the prank on him, drawing cheers and laughter from the crowd. The joke quickly turns serious as Remus loses control of the storm, leaving Snape battered until Dumbledore intervenes. The hall falls silent, and the Marauders are left shaken by just how far things went.
