Remus—in his current condition—being knocked to the floor by the Carrows was
enough to tear Mia's attention from Snape, and the moment her eyes turned away from
him, he aimed his wand and roared, "Langlock!"
Rendered silent with her tongue stuck to the roof of her mouth, Mia was unable to
cast any spells verbally. That was when Snape began attacking with a renewed vengeance.
"Locomotor Wibbly!" he called, causing her legs to collapse beneath her. "Expelliarmus!"
Her wand flew across the room.
She glared at Snape and felt a slight tingle—similar to when she shifted into her
Animagus form—and wondered if, in her anger, her brown eyes had turned amber.
"You son of a bitch!" Sirius shouted, rushing toward Snape, wand outheld. A
sudden and silent shield flew up, blocking him from moving further. Sirius whipped his
head around and caught sight of Professor Higgs holding his wand up with a smarmy smile
on his face.
"Twenty points from Gryffindor, Mr Black, for interfering. Keep your distance, all
of you. I'd like to see how this plays out." He chuckled at the sight of Mia, wandless,
silenced, and immobile from the waist down. "Finish your duel, Mr Snape."
Snape looked confused at first, but then glowered down at Mia and raised his wand.
His lip curled as his eyes filled with contempt. He began his spell, "Stupe―"
Ginny, you'd appreciate this, Mia thought, squeezing her eyes shut as she cast her very
first non-verbal, wandless Bat-Bogey Hex.
Before Snape had a chance to finish his spell, he sneezed, letting out a loud scream
as a massive, bat-shaped bogey crawled out of his hooked nose. It grew wings and began
attacking him viciously, slapping its wings against the sides of his face.
"Finite Incantatem!" James hollered.
Mia let out a gasp as her tongue was released, her legs regaining sensation.
"Accio wand!" Her precious vinewood wand flew into her hands. Aiming the wood at
Snape, she shouted, "Stupefy!" eyes blazing as Snape fell backward, hitting the ground
unconscious.
She stood up and looked around the room.
Frank was sitting next to Lily while Alice helped him nurse a head bump he had
received from being stunned. James hovered protectively over Remus, who had also been
revived, though his eyes were trained on the unconscious Snape. Elora Zabini and Mary
