Sirius sauntered into the room with a smirk on his face and a spring in his step.
"Hello there Gryffindorks." He sent a lacivious smile over to Molly and Lily, then made his way to the front of the classroom.
"I know, I know, you're all overawed by my presence, and I honestly can't say I blame you. I amaze myself on a daily basis. But I think it's time you children faced a few facts!" He jumped up on one of the desks and surveyed the room. "What is this? Defense Club? Honestly, this might just be the saddest collection of human beings I have ever seen. We have the Fearless Leader," he turned to James with a sneer. "Who's head is so far up his own ass that he can't even see that this fight is already lost. We've got the desperate, whiny loser clinging vainly to his coat tails," he tipped his hat to Peter. "The fat, shrewish bitch who can't keep her nose out of other peoples business," he winked at Molly, "and who else. Who am I missing... Oh yes, the mudblood slut who's running two men through their paces on a daily basis. Really, I'm terrified. You lot are going to change the world."
