Year Five: Alex Has Had It. (non-canon)
Harry probably should have seen that coming. He and Alex had come across a crying first-year, comforted by the Weasley Twins. There was steel in his sister's gaze, and he didn't think he liked it. And then Umbridge had shown up, sweetly smiling at them.
"It's as I've always said, Mr. Potter. Naughty children deserve to be punished."
Alexandra's back had gone ramrod straight. "That's it," she murmured, low enough that only Harry heard her. "This ends now."
"Something to say, miss Potter?"
She smiled. It was a very unpleasant smile. "Sure. Accio wand!"
With a startled cry, Umbridge found her wand flying out of her hand, and into Alex's. She frowned. "Tut, tut, miss Potter. It's not very proper to steal another's wand, is it? Now, please hand it over to me."
Alex let loose a humourless laugh. She holstered her own wand, taking hold of Umbridge's. "Sorry, Professor. I'm afraid you're relieved of duty. Avada Kedavra!"
Everyone present stared in horror at the bolt of green light that leapt from the wand, striking the woman in the chest. The girl smiled sweetly, too sweetly, and stepped closer. "Ignis Maleficum!"
A fiery serpent leapt from the wand, crossing the distance to the corpse in seconds and devouring it whole. Alexandra smiled at it. ~Come here,~ she hissed. Dutifully, it obeyed, slithering to her, and staring up almost hungrily. The girl held out the wand – Umbridge's wand – and dropped it into its maw, the snake extinguishing almost as soon as the wand burnt to ash.
Nonchalantly unholstering her wand, the girl made a sweeping motion, banishing any of the remaining ash, before turning to her gaping audience with a cheerful smile.
"What happened here remains between us, right?" She was fingering her wand. Everyone nodded in wordless agreement. She beamed. "Wonderful! I'd hate to start throwing Obliviates around. What about you? You agree? Good! I think we're done here."
She grinned for the last time, and flounced away.
Nobody spoke for quite a while.
