Sirius Black bounded into the common room, grey eyes glimmering with the mischief that could only mean he'd done something he shouldn't. He made his way over to the fireplace, raising his hands in the air dramatically; he had always had a penchant for dramatics. "Fellow Gryffindorians!" he announced ostentatiously. All eyes were immediately on him, just how he liked. He grinned widely, catching the eyes of his fellow Marauders in their usual corner. "I have once again defeated that greasy Slytherin Snivellus! You may all send thank you gifts directly to me, of course." Sirius took a theatrical bow, spurring mild applause and laughter from the common room. When he straightened he made his way to the back corner.
His approach was met with reproachful eyes from Remus, admiration from Peter, and curiosity from James. Sirius grinned widely, glancing over his shoulder to see if people were still looking at him. They were. There was always someone looking at him; sometimes he was just too thick to notice. James raised his eyebrows, obviously wanting to know what had happened. Sirius sighed a little too loudly before standing up. "Well, if you insist, Prongsy." He launched into an incredible tale involving the Slytherin in question, a group of 'distressed' second years, and how he so kindly saved the day and revealed said Slytherin's underwear to some passing sixth year girls. Sirius made sure to speak loud enough so that everyone in the common room could hear. Always with the theatrics to get attention, of course.
Sirius took another bow that was again met with applause before sitting back down. He leaned over to Remus, a grin on his face. "Actually, he just looked at me and I hexed him," he confessed nonchalantly. James and Peter laughed, but Remus merely rolled his eyes and tried to hide his smile. Sirius leaned back on his chair so it was resting on two legs. He casually slung his hands behind his head and grinned to himself. He had succeeded in making his mates laugh. Mission accomplished.
