A/N: For the Sherlock Competition (Part 1, Prompt 7: write about someone irritating)
Victoire starts to compliment Dominique on her jumper but stops herself, fists clenching as she recognizes it. "Is that mine?"
The twelve year old glances down at the snug peach thing, shrugging. "Looks good on me, though, don't you think?"
"Dom!"
"What?" Dominique asks innocently, nervously adjusting the neck.
"Take it off right bloody now! I can't believe you would go through my things again!"
"I can't take it off. I'm wearing it."
Victoire strides dangerously closer, grabbing the jumper and pulling it. "You're so annoying! Why couldn't I have two brothers?"
OoOoO
"Did you see me, Vic?" Dominique asks, tugging her sister's sleeve after victory over Ravenclaw. "Bam! I was on fire! Unstoppable!"
"Shut up, Dominique," Victoire says, eyes rolling. "You barely even did anything."
Dominique shrugs, waving her words away. "Yeah, but I was pretty ace, right?"
Victoire scowls, eyes finding Teddy who looks anxious to escape the crowd. "I'm busy."
"Come on! We're celebr-"
"Merlin's beard!" Victoire snaps, pushing the younger girl away in irritation. "I said I was busy! Go bother someone else."
OoOoO
"Vic, can you help me with my Herbology essay?"
Victoire takes a deep, steadying breath, trying to calm her nerves. "No," she says, putting the finishing touches on her own homework. "Go ask Lucy."
"But you're, like, brilliant at this!" her sister insists. "Please?"
"I'm your sister, not your tutor," Victoire says in clipped tones. "I already did third year Herbology. I'm not doing it again."
Dominique stares at her feet, cheeks going pink. "Yeah. All right," she mumbles, her voice thin, about to break.
Victoire pushes away her guilt, returning her full attention to revising her essay.
OoOoO
"Hey, Weasley, is it true your dad's a werewolf?"
Victoire freezes, body going cold. She peers around the corner, finding Dominique pressed against the wall by a Slytherin girl.
"Bet your house is full of fleas. What's the matter? Wolf got your tongue?"
Victoire storms over, wand drawn. "If you value your sanity, bugger off, mate," she growls.
The girl releases Dominique, rounding on the older girl. "What you gonna do? Give me detention?" she snorts. "Make me write lines?"
Victoire shakes her head, wand pressing against the Slytherin's stomach. "No. Much worse," she says, her voice eerily calm. "Mess with my family again, and you will see just how wolfy I can get. Got it?"
In spite of the girl's bravado, her eyes flicker anxiously between the sisters. "Yeah. Whatever," she says before turning to Dominique. "This isn't over, Weasley."
When she's gone, Dominique looks up at her sister. "Thought you didn't like me."
"Sometimes, I don't," Victoire admits simply, pulling her into a hug. "But I love you. You may be a pain in the bum, but you're my pain."
Dominique laughs. "Good."
