"Considering most physics tended to stay away from the war and more so from Albus himself." –Aster and Camellia, "Separated"

Albus Dumbledore crept past the guards into his one-time friend's stronghold. None of them noticed him, for he was under a spell of invisibility; light passed through him while still conveying images to his eyes, in precisely the way that the laws of refraction, had they been present, would not have allowed.

"Muffliato," he whispered, pointing his wand at the floor. Obligingly, the hard tile altered itself so that the impact of his feet upon it would produce an infinitely small sound intensity, however finitely great the power exerted might be. Thus concealed, he ran through the grand foyer and adjacent hallway, and arrived at the door of the throne room.

This door was heavily shielded against invasive spells, but the lintel about it was less well guarded. Albus searched until he found a small spot where the wards were sufficiently weak; then he blew a soundless hole in it with his wand (which suffered no recoil, since the Third Law of Motion was nowhere about), and shrank himself down till he was small enough to pass through it – which, naturally, reduced all his component atoms to a size well below the Planck limit.

Conjuring a tiny spyglass out of nothing (since matter could be created and destroyed when he was about), he levitated himself up to the hole, with blithe disregard of the Law of Gravitation, and peeked through. Yes, there his foe was – and, at the sight of him pondering a book of Hallows lore with the same old quaint gravity, Albus felt a pang of nostalgic grief. But he swallowed it down, Vanished his spyglass, and leaped through the hole, resuming his natural size as he descended.

"Come, Gellert," he said, raising his physics-banishing wand as Grindelwald looked up sharply. "Let us end this."

"Ginny nodded and smiled meekly. Harry couldn't stop gapping at her." –JustForkIt, "Uninhibited Ginny Weasley"

"The engine's sure to misfire if you keep doing that, Harry," said Ginny, still in her most deceptively demure tone.

Harry forced himself to ignore her. Spark plugs weren't so expensive; he could always get another – or, for that matter, he could just take his wand or a pair of pliers and undo the gapping he was performing on this one. Anyway, he didn't dare let up now; it was only the slow rotation of the steel gap gauge, as it slowly increased the distance between the plug's two electrodes, that was keeping the fey-possessed redhead from lunging at him with her fatal touch.

"Harry, there's nothing to be afraid of," Ginny said cajolingly. "When Apavarga entered into me, she filled me with the supreme potency of primal magic. I don't need an individual personality anymore." There was a brief twitch at the edge of her mouth, as though what remained of Ginny was attempting to contradict this; next moment, however, it had passed as though it had never been. "And it'll be the same with you; you'll have something so much better, you'll look back and laugh at the time when you thought it important to be you. Come on, put down the iron alloy."

The plug slowly crept up on the .040″ mark.

"Harry, you can't keep that up forever." There was the faintest hint of a snarl in Ginny's voice now. "Once you reach a full tenth of an inch, you'll have nowhere left to go, and I'll get you anyway. What's the point of delaying the inev…"

"Petrificus Totalus!"

Ginny, caught off guard, turned sharply a second too late; as the spell hit her, her body stiffened and crashed to the ground, and Harry dropped plug and gauge with a relieved exhalation. "Thanks, Hermione."

"Well[,] for one it would basically create a soul bound between the pair of us." –Ashabel, "A Bloodless Bond"

"No, it wouldn't," said Harry. "At least, it doesn't have to. There's this potion you can take beforehand that…"

Daphne groaned. "Harry," she said, striving for patience, "Contraceptive Potions don't work in Hogwarts. The wards against evil magic are too strong; circumstances here inevitably conspire to foil all but the most skillful, deliberate efforts to violate the sanctity of human nature. And don't say that's not what you were proposing," she snapped, as Harry opened his mouth to respond. "I don't know what your Muggle relatives taught you, but, where I come from, we know that human sexuality is as sacred as its products; when you treat it as something you can just get kicks from whenever you like, without any respect for what it is or does, you kill something inside yourself, and grow that much closer to the supreme contempt for human life that you, Harry Potter, are supposed to be learning how to overthrow."

Harry flinched. "Okay, fair enough," he said. "I guess it was a bad idea. It's just… I don't know…"

"Oh, I do," said Daphne, in a rather gentler tone. "You're a lonely young wizard burdened with terrible purpose, and I'm a born warriors' rest. It's perfectly natural that you'd have that thought." She smiled. "And who knows? Maybe someday, when we're out of school and you've defeated the Dark Lord, it'll be time for us to make a new soul together and bind it to ourselves. But not now, Harry; not this way."

"'I was just trying to make Euros happy!' the younger girl explained, glaring at her cousin." –LeighaGreene, "The Reason(s) 'Mary Potter and the Chained Servant' Still Isn't Done"*

Zéphyrine blinked, and seemed to struggle momentarily for words. "Er… Hermione," she said at length, with all the grave lucidity her French heritage could supply, "you know they're just coins, yes?"

"So?" Hermione demanded. "Money has a right to happiness, too. Can you imagine what it's like to be a Euro – or a pound, for that matter? To know that you'll only ever be valued for your symbolic utility – that nobody will ever care about your own beauty and integrity as a unique physical entity, because all that matters is whether they can take you into the Forum des Halles and exchange you for a new pair of shoes? These lovely creatures deserve better than that – yes, you do, sweethearts," she crooned to the heap of brass-rimmed coins in her hand.

Zéphyrine stared for a long moment, and then shook her head. "Maman?" she called, glancing over her shoulder toward the kitchen. "Your side of the family is insane."
