Hermione Granger could hardly see. It was dark and her vision was blurred from sheer exhaustion; some of her annoying locks were also getting in the way and her palms were starting to be sweaty. All around her, everything was a chaos of blinding lights and she felt slightly dizzy, like one might find herself in Vegas. Suddenly, her back collided with someone else's. Friend or foe? Before she could inflict any damage (mostly to herself) she heard him mutter something she couldn't make out in the midst of all the noise and shrieks of the battle.
"What was that, professor Snape?" she asked, forgetting about the battle, the enemies, even her wand, which hanged limply and without aim in her right hand. She twisted her head slightly to try and catch a glimpse of the tall wizard fighting the evil back to back with her. Was it possible…?
"Hermione!" she heard Harry call.
"Not now" she whispered. "Well?" she asked again.
"I said" Snape repeated tersely "that you were right-"
"Hermione!" interrupted Ron.
"Not now!" she cried. Not when she was about to accomplish what she had been working on for seven long, tough years "And?"
"And that your plan was better than mine-" he said in a chagrined undertone.
"Hermioneeee!"
"Not NOW, damn it!" she shouted. "Aaaand?"
"And" he added through gritted teeth "You are…"
Someone tapped her in her shoulder.
Snorting, but not even bothering to look, she casually let a green jet of light escape her wand.
"Now, professor Snape, did I just hear that you pronounced me an apt potions student?" she said quite charmingly, taking a reasonably stunned Severus Snape by the arm and leading him away from a very shocked multitude and a pretty much dead Dark Lord.
