"Taking on Umbridge? I don't think I've seen her this excited since she broke my
nose third year."
"That made everyone who saw it a little happy. 'If an injury has to be done to a man,
it should be so severe that his vengeance need not be feared,'" Theo said with an
entertained smile.
"What do you think Umbridge did to incur this kind of wrath?" Draco asked.
"Other than exist? By my count, she's called her a Mudblood twice already."
"Minister!" Umbridge finally broke, turning to Kingsley with a shout and thus
pulling Mia's focus away from listening in on the Slytherins as pandemonium erupted
around her. "I request that Lady Black be removed from the Wizengamot immediately!"
Finally, the crowd began to calm as Umbridge's volume increased, everyone waiting
to see how Kingsley would side. Those who knew the man waited to see how the blood
purists would react when he made his choice known.
Before the Minister could say anything aloud, Mia spoke up, her voice calm and
rational, "If Madam Umbridge has justification for having me removed, I willingly give her
the floor. If not, my accusations stand."
"Miss Potter, you're aware of the seriousness of your accusations?" Kingsley asked
her as though he had not been informed of her desire to ruin Umbridge. "You are accusing
a member of the Wizengamot of using an Unforgivable."
"Yes," Mia affirmed, "against the former Minister for Magic, Harold Minchum."
Umbridge briefly flinched at the specified accusation, and Mia's inner Animagus shivered
in delight. "And, lest we forget, I also accused her of forging his signature on legislation
she wanted to pass."
Umbridge huffed incredulously. "This is offensive! As a victim of the Imperius Curse
myself," she said, fanning her face with her hand to further show how emotionally
distraught she was by the accusations being thrown at her, "I am more than aware of how
difficult it would be to even begin to investigate such a horrendous claim."
Mia smiled at the woman, an action that apparently continued to irritate. "Yes, it
would take wand monitoring after a suspicion has been aroused, signed by an Auror and
registered with the Improper Use of Magic Offices. And, considering that the person being
monitored is aware of being monitored, they're unlikely to perform said Unforgivable
Magic."
