the Gryffindor table where they met the shocked expressions of James, Peter, Remus,
Frank, Alice, and Mary.
Mia, however, looked full of righteous anger, and Sirius sat wide-eyed.
"You're horrible!" one girl screamed, running out of the Great Hall in sobs, and Mia
growled, as her inner Animagus stirred.
The formerly beautiful brunette Ravenclaw, along with sixteen other girls, had their
faces horribly disfigured by a series of red and purple pustules spread across their
foreheads, clearly spelling: S-L-A-G.
Those who were in the A.D. knew exactly who had set the jinx upon the girls, so
Mia knew her time was limited if she wanted to stay ahead of the rumours—true or not—
that she had cursed her fellow students.
"I'll be going to the hospital wing," she explained with a calm tone as the rest of the
Gryffindors stared up at her in silence. "I'll collect an antidote for Peter while I'm there."
The struggling boy let out a distraught cry, breaking James's Silencing Charm in
displeasure at the idea of being forced out of love with one Elora Zabini.
When her friends continued to gape at her in shock, she sighed. "Don't worry. I'll
tell Madam Pomfrey how to take the jinx off of them."
She knew back in her original timeline, the sneak, Marietta Edgecombe, still bore
the scars of her betrayal of Dumbledore's Army, but this, Mia could admit, had been a little
extreme. She had merely wanted to make a point: no one messed with what was hers.
"We still on for Hogsmeade?" she asked Sirius.
"Fuck yes," Sirius said, staring at her as she stood there, looking just a bit crazed.
When she smirked at him, his grin widened, and he leered at her excitedly as she walked
out of the Great Hall in the wake of the chaos she had created on his behalf. When she
opened the doors to leave, Sirius could still hear the echoing sound of crying coming from
Mia's victims.
Clearing his throat, he sat back and tried to subtly put his hands beneath the table
to adjust a sudden problem. The moment he cupped himself through his trousers, James
punched him in the arm, causing Sirius to accidentally hit himself in the dick. Groaning, he
leant forward and put his face on the table, coughing. "You... c-cock."
"That's still my sister!"
