Umbridge laughed. "A hand of mercy, is it? Or is it one of friendship?" she asked
mockingly.
"Neither," Mia whispered. "Incarcerous."
Ropes were conjured out of the floor and flew up toward Umbridge, wrapping
around her arms, legs, waist, and throat. She looked up with wide eyes just as Mia closed
her fist tightly. The ropes, in turn, tightened, pulling the woman to the ground with a
sickening thud, binding her.
Umbridge screamed against the tightening rope around her neck.
"Apologies, Dolores." The click of Mia's heels on the floor echoed as she walked
toward Umbridge gracefully. "Are you not skilled at wandless magic? Perhaps you should
have studied harder in Defence Against the Dark Arts. Theory isn't everything, you know.
Then again, perhaps when you were in Hogwarts you learnt defensive spells in a secure,
risk-free way. Perhaps, when you were in Hogwarts, you weren't exposed to irresponsible
wizards, not to mention... extremely dangerous half-breeds. Then again, I suppose if one
studies theory hard enough.. ."
Umbridge made a loud choking noise, and Mia adopted a patient expression.
"Speak up, dear. Would you still like me to fight you?"
When Umbridge said nothing and instead snarled, eyes narrowed, Mia inclined her
head and picked her own wand out of her enemy's hand. "Avis," she said, her tone full of
sweetness as crows burst from the tip of her wand, flapping their wings in the air and
circling around, waiting for a command.
Harry, Sirius, and Remus all grinned at the sight of the birds, having seen this
particular spell before, and prepared for the crows to attack the bound woman. The
Wizengamot, expecting the same, all sat forward on their chairs, suddenly enthralled with
the path the duel had taken.
What no one expected was for Mia to whisper, "Draconifors."
The flying black crows gave a sudden caw as their feathers turned into scales, and
each bird transfigured into a small, black dragon.
Umbridge screamed in terror as Mia said, "Oppugno!"
The circling dragons overhead rapidly flew down, screeching loudly as fire ignited
in their throats, spewing forth from their mouths onto the thrashing witch below.
