Professor McGonagall thundered across the floor on the back of a hippogriff, riding as if she'd been born to it, screaming "CHARGE!!"
The students now saw her in all her glory, as they had never seen her before. She was dressed in the tartan of her clan, painted in blood and woad, her tangled hair was flying in the wind, and she was brandishing the biggest claymore the world had ever seen.
Nobody said anything, including the Death Eaters, because they were all too busy staring with open mouths.
Finally Neville started applauding, and the rest of the students joined in. Lee Jordan whistled. Dumbledore shook his head, recovered his senses, and called out, "Cut!" just as the hippogriff reared dramatically against the rising sun.
"That was beautiful, Minerva, but it won't do ... I'm afraid if everyone got to see that side of you, there might be a violent revolution."
McGonagall ignored him. She skidded to a stop, brandished the sword once more, and bellowed: "FOR FREEDOM!!" eliciting a great cheer from the student body. Even Filch looked impressed.
