"Remus? Mooney? RRREEEMMMMUUUSSSS!!!!" The young werewolf sat up and glared at a familiar black haired Gryffindor. Groaning he threw the first thing he got his hands on at the smirking Sirius Black. That happened to be his beloved book.
"Oww…" Sirius mumbled as he picked up the book that had been unceremoniously chucked at him. "Hey, what is this?"
"Sirius, give it back" Remus order once he realized what he had thrown. Sirius flipped the leather bound book over to look at the cover. "Sirius" Remus said again; his move had not improved.
"I don't think I will" Sirius said, his signature smirk dancing across his lips. Remus bit his own lip. Soon Remus found himself chasing a large black dog around the room trying in vain to retrieve his book. With a bark and a bound Sirius ran down the stair, changing into a human as he went. The werewolf attempted to follow his idiot friend but failed quite miserably.
Sirius Orin Black was sitting in the room of requirements, smiling to himself. He had found Mr. Mooney's diary.
