Harry Potter and the Goblet of Fire

4th year.
Malfoy and his friends—Blaise Zabini, Pansy Parkinson, Gregory Goyle, Vincent Crabbe, and Lianna Vaintor—have bullied Harry, Ron, Neville, Hermione, and many other students since their first year. They also hated Muggle-borns and half-bloods.

Lianna Vaintor was a 13-year-old girl who knew cruelty; she was full of it. Of course, she hated those with tainted blood, even though she didn't think so herself. This was instilled in her from childhood by her parents—Celestia Vaintor (Crows) and Bertley Vaintor, former Slytherins who are now Death Eaters. Almost all Slytherins have Death Eater parents.
Appearance: She has long, flowing hair of a light gold—not bright, but muted, as if touched by an ashen haze; it always falls perfectly, not a single curl daring to disturb the strict line of her hairstyle. Her eyes are steel-gray, almost metallic: warmth rarely glimmers in them, but calculation and a subtle, barely perceptible mockery are easily discernible. Her facial features are delicate and aristocratic: a straight nose, clearly defined cheekbones, and lips that she purses slightly when listening to someone she considers unworthy of attention.

Lunch is taking place at Hogwarts. The students are enjoying their meal in the Great Hall, especially Ron Weasley. Hermione Granger, Harry Potter, and Ron Weasley are discussing something, while Ron eats. Suddenly, the Malfoy gang approaches the trio. Lyanna is the first to speak up: "Oh, my God, you're eating, aren't you?"
Hermione: "It's none of your business, Vaintor," she said with a furious expression on her face ; Lyanna wanted to object, but Draco stopped her and answered himself : "Has the Mudblood found his voice yet?"

Ron:Shut up, Malfoy.

Draco: "What if I don't shut up? Will you hit me? Even if you don't dare. You're just Potter's ponytail." Malfoy said with a smirk, his henchmen scattering to support their friend.

Lianna: You are a bunch of losers.
