"Mr. Longbottom, we have been through this already! It is pronounced Gemino, not Gemeno. It is a simple duplicating spell, what is wrong with this class today?"
Proffesor McGonagall was stricken. What had happened to the Gryffindors? Suddenly, the Ravenclaws, Hufflepuffs, and even the dumbest of Slytherins have surpassed them in grades. Even Hermione Granger was falling behind! What could have possibly have ensued for this to happen?
An hour later…
"Please, guys, I need to practice this charm for Flitwick. I'm dead if I can't get it right."
"Neville, it was due a week ago!" Hermione was right. And even Harry and Ron knew that.
"I know, Hermione, but Flitwick said I could get one more go, to save my grade."
"Okay, Neville. Let's get this over with. We only have two minutes to get to Transfiguration."
Right then, every single Gryffindor came down from their dorms and walked into the common room, at the same time as Neville screamed "Confundo!", and everybody fell to the floor, including Neville and the Golden Trio. The Confundus Curse that Neville had sent towards Hermione, as practise, had backfired, and hit every single Gryffindor student in Hogwarts. Thanks to Neville's dull-wittedness, the spell was not strong enough to completely confuse the targets, as it was supposed to, but it still hit them.
On the way to Charms, the Gryffindors tried to stay together- and for good reason- because they were worried that someone would forget the way. The charm still hadn't worn off, and at least two Gryffindors had gotten lost on the way to class. After almost twenty minutes of walking around the school (and many times asking for directions), they finally found their way to Charms. The group of sharp Ravenclaws, who were already sitting at their desks, all turned and stared at the befuddled Gryffindors at the same time, with astounding accuracy.
"Sorry, professor," mumbled Hermione, and she slowly shrank into her seat, with the rest of the Gryffindors following close behind her.
"I hate to say it, but ten points from Gryffindor. It is unacceptable for students to be late to class. And Ms. Granger, you are usually here minutes early, with your homework on my desk! What has gotten into you, students?"
The Ravenclaws chuckled, and whispered to each other about the Gryffindors, tripping over each other just to sit down.
"Mr. Longbottom? I presume you have something to show me."
Neville looked at the professor with the same expression he had been wearing for an hour now; confused, puzzled, perplexed.
"Your Confundus Curse, Mr. Longbottom."
"Oh, right."
Neville stood up from his seat and slowly sulked to the front of the class. He had already messed up this spell once today. It would be horrible if he also ruined his professor and all the Ravenclaws.
"Ugh, um, un confusa?"
Just like before, sparks shot out of Neville's wand and all the sparks landed over himself and the Gryffindors.
"Professor, what did I just say?"
"Not the Confundus Curse, Longbottom. That was the counter curse. Though I am surprised, I haven't taught it yet."
"Neville Longbottom!"
He was about to have a nice little chat with the Gryffindors- especially Hermione.
