Mia opened her mouth before she even had any idea of what she might say to him,
but her words never left as someone else intruded on the moment.
"Hey there, Black."
Everyone turned to see Elora Zabini walking over to them, wearing expensive-
looking green and black robes. The Slytherin ignored everyone, save for Sirius, who winced
at the very sight of her.
"You're looking good this year. Summer treat you well?"
Sirius scowled at her, nothing but loathing in his eyes. "Treated me like shit,
actually."
"Shame. Want to ditch these.. ." Elora trailed off, looking down her nose in
distaste at the gathered Gryffindors, "people and take a walk with me?"
"No. Just like every other time you've asked. And I'll thank you to stop telling the
Ravenclaws that you shagged me. I wouldn't be caught dead with my cock in a snake. All
that venom would make it rot off."
Elora laughed, unphased by his insult. "Oh, sweetie. I'll do and say whatever I like."
"Hey, Zabini," Mia said, her own venom coursing like fire through her veins as she
glared at the Slytherin witch. Without another thought, she reached into the pocket of her
robes, fishing around until she felt metal against the tips of her fingers. "Can you swim?"
Elora glared at Mia as though she were an idiot. "Of course I can, you stupid little
blood-trait―"
"Good. Catch." Mia tossed a shiny Sickle toward Elora.
Instinctively, Elora caught the coin and then looked up at Mia, confused, before a
bright blue light encompassed her and vanished her away with a startled scream.
Everyone stared at Mia with wide, terrified eyes.
"What the fuck?" Sirius shouted.
"Remember that Portkey modification I was making?" Mia asked conversationally,
as though she hadn't just vanished a girl. "I figured out how to do it."
James took in a deep breath, moving to Lily's side to rub her shoulders as she began
hyperventilating. "Ignoring the fact that you basically just attacked another student in front
of the Head Boy and Girl and another prefect... again," he said, looking concerned and
exasperated—which Mia felt was just a smidge hypocritical of him. "You linked the Portkey
to... ?"
