"What are you reading?" Sirius asked curiously as he walked into their dormitory.

James shrugged, "Some... muggle comic."

"Oooh, Lemme see." Sirius said, wrenching the comic out of James' hands and looking at it. "It's one of those... super hero thingies!" he said excitedly, tossing the comic back at James and jumping up onto his bed.

"Yeah. What about it?" James asked, smirking in an amused way.

Sirius ripped down the curtains from his bed and tied it around his neck like a cape, magicking it to look like it was billowing.

"They're awesome!" he said, striking some sort of karate-like pose.

James stared at him for a split second before jumping over his bed and landing on the floor, using it as some sort of fort, peeking over the top. He took out his wand, shooting small sparks at Sirius.

"Buuu, buuu!"

Sirius deflected each spark and put his hands on his hips, giving an evil, barking laugh. "You are no match for... The Rogue Dog!"

And that's when the door opened... and both boys slowly turned to see who it was.

"...What are you two doing?" Remus asked, his eyebrow raised and a look of utter confusion on his face.

There was silence before James shot a small spark at him.

"...Buuu."
