"Hey, Padfoot?" the tall and handsome Gryffindor asked his friend.
"Yeah, Prongs?"
"Is it just me, or is this really boring?!"
Sirius laughed and agreed. He looked over at their silent friend, Remus, but he was still too engrossed in his book to take any notice.
"Yeah, but you know Moony has to get his homework done now before his… 'furry little problem' makes it impossible without eating the parchment!"
James smiled and walked across the library to the window. He looked out and saw their… let's say 'friend' for now… Peter. He was busy in the grounds clearing up after Sirius' latest prank left ten tons of hippogriff dung lying around. James couldn't hear him, but he could imagine Peter stuttering over the words.
"S-s-scourgify…"
And, sure enough, with one flick of the wand it was Peter, not the grass, which was covered in the unsavoury substance.
James laughed loud enough to earn an angry look from the librarian, and he shrugged, then turned his attention back to his friend, floundering about, not even trying to use magic anymore. From his high vantage point, James opened the window and pointed his wand at Peter, but he was moving about too fast for him to aim.
"Ugh, stay still." He muttered, frustrated.
"Hm?" Sirius looked up and joined him at the window. He laughed just as loud as James, but the librarian just smiled at him and twirled her hair around her finger. He didn't notice.
"So, Pettigrew's in a bit of a struggle. Should we help him?"
"A bit longer…" James stared at Peter, dying of laughter inwardly as the fat boy rolled about on the grass trying to clean himself, and all of the students either stopped to laugh or ran away as fast as possible (probably due to the smell).
"Okay, now."
Sirius and James pointed their wands at Peter at the exact same moment as Peter was attempting to once again clean himself using magic, and they both whispered, "Scourgify!"
Sure enough, one of the spells hit and Peter was once again clean. (Or as clean as he was before the prank. His shirt was still covered in stains.) He stood up, looking extremely pleased with himself as the jeering crowd dissipated.
On their way back to Remus at the table, James and Sirius were arguing about who's spell it was that hit.
"It was mine!" Sirius yelled. "I was on your right, and the spell on the right hit. Yours was miles off!"
"Pfft!" James' snort earned another look from Miss Pince. "Our spell paths crossed, because yours was miles off!"
"Guys."
Both arguing boys stopped talking and turned to look at their friend Remus.
"What is it Moony?"
"It's just…." he stared at his book, "Do you feel like someone is watching us?" He sniffed in the fashion of a hunting wolf, but was careful not to raise his eyes or look worried.
James laughed. Remus was so paranoid, it was hilarious sometimes. He was constantly worried that someone would find out about his secret and then no one would want their child going to school with…well… one of him.
It was rubbish, of course. Remus Lupin was one of the smartest, kindest, hard-working students in the school. (Not counting Hufflepuff. Who counts Hufflepuff?!)
