Something Undefined

Duel

Hermione Jean Granger, a fifth-year Gryffindor at Hogwarts School of Witchcraft and Wizardry, was the brightest witch of her age as regarded by several of her professors, well almost all. Except for one particular sallow-skinned, hooked-nosed enigmatic man who never permitted any soul to take a peek into the dark deep fathoms of his personality. He was Professor Severus Tobias Snape, a  Slytherin who especially had a critical analysis of the activities of Gryffindors. Others saw this as Snape's usual personna but only Hermione knew how much it bothered her. It killed her inside that she could never share her thoughts with anyone on the matter.

Being a Muggleborn, Hermione knew all about the discrimination faced by her kind and she couldn't cease herself to think of methods to cope up with Draco Malfoy. He had crossed his limits that day.
It was a normal Tuesday and the fifth year Gryffindors reached towards their Potions classroom for the last lesson of the day. They had Double Potions with the Slytherins. Lunch had been a couple of hours ago but still a redhead boy was munching on Pixiepuffs. Harry was annoyed with Ron's habit of sneaking snacks into classes.
"Hey 'Mione, you should try these Jelly Slugs. They're delicious," Ron said while stuffing a handful of green and blue jelly creatures in his mouth.
"Thanks Ronald, but I would most definitely like to pass that offer for I would not like to wish Prof. Snape with my mouth full of leftovers!" Hermione kept her voice to a low note.

"Eating slugs again Weasley!! I bet that you don't get those anywhere near that shack of a house of yours. Or is it the fact that you're family can never afford to buy a box of these? Listen Potter! Why don't you give your filthy friend a bit of your fortune?" A cold voice mocked the Golden Trio. Draco Malfoy was standing in front of them with his sidekicks.

Harry was quick enough to point his wand at Draco. "You say one more word Malfoy and I swear that you will not be able to utter one more syllable."

"Huh... trying to scare me Potter. Let's see whose tongue gets ripped in two!" Draco positioned himself in his duel stance in a flash.

Hermione, being the only intellectual one, intervened. "Stop it now, boys. You are no more in your first year trying to get each other into trouble. We know Voldemort is back. If we don't stick together, nothing will exist."

"Shut up, Mudblood!" said Zabini and a copy of 'Mudbloods and how to spot them' was thrown right at Hermione gashing her forehead.

She gasped sliding down to the floor.
"Oye, you're gonna get a piece of us for that!!" said Ron as he jumped on Blaise punching him in the face. In a couple of seconds, Harry, Ron, Zabini and Malfoy were directing hexes in their enemies' direction. All the other students backed away to the sides of the corridor but none went forward to console a painstricken Hermione. The standard and level of both the attacking and defensing spells began to raise with each turn.
