Harry Potter and the Methods of Rationality

"She would have come to that same place in due time," Albus said, the distant sad look still in his eyes. "If someone is meant to become a hero then they will not listen to our warnings, Minerva, no matter how hard we try. And given that, it is better for Harry if Miss Granger does not fall too far behind him." Albus produced, as though from nowhere, a tin which flipped open to reveal small yellow lumps, she'd never been able to figure out where he kept it and she'd never been able to detect the magic involved. "Lemon drop?"

"She is a twelve-year-old girl, Albus!"

Within the windows, barely visible in the evening gloom, fishes swam in the black waters; illuminated by the bright shine of the Slytherin common room as they came closer, fading into darkness as they swam away.

Daphne Greengrass was sitting in a comfortable black leather couch, her head collapsed into her hands, glowing golden-yellowish as bright sparks of white light winked in and out of existence around her.

She'd been ready to be teased about liking Neville Longbottom. She'd been expecting to hear a lot of snide remarks about Hufflepuffs. She'd thought of whole reams of snappy comebacks for it while she was on the way back to the Slytherin dungeons.

She'd been looking forward to being teased about liking Neville. Being teased about that sort of thing meant you'd grown up into a real girl.

As it turned out, nobody had worked out that her challenging Neville to a Most Ancient Duel meant that she liked him. She'd thought it would be obvious but no, nobody else had even thought of that apparently.

It was always the hex you didn't see that hit you.

She should've just called herself Daphne of Sunshine, like Neville of Chaos. Or Sunny Daphne like Sunny Ron. Or anything except Greengrass of Sunshine.

Greengrass of Sunshine.

It had gone from there to Greengrass of Sunshine and Blue Skies.

Then someone had added Snow-Topped Mountains and Frolicking Woodland Creatures.

Currently she was being referred to as the Sparkly Unicorn Princess of the Noble and Most Ancient House of Sparklypoo.

And some cursed sixth-year girl had hit her with a Sparkling Jinx, she hadn't even known there was such a thing as a Sparkling Jinx, and Finite Incantatem hadn't worked, and she'd asked older girls who she'd thought were her friends (she had apparently been wrong about this) and then she'd threatened the caster with grievous political mayhem wreaked by her father and nonetheless Daphne Greengrass was still sitting in the Slytherin common room with her head in her hands, sparkling brightly and wondering how she'd ended up as the only sane person in Hogwarts.

It was after dinnertime and they were still at it and if they didn't stop by tomorrow morning she was going to transfer to Durmstrang and become the next Dark Lady.

"Hey, everyone!" said the Carrow twins dramatically, waving an issue of the Daily Prophet. "Did you hear the news? The Wizengamot just ruled that 'let's see what you got' constitutes a lawful challenge to be fought until the challenger lies down and has a nap!"

"How dare you insult the honor of the Sparkly Unicorn Princess!" shouted Tracey. "Let's see what you got!" Then Tracey lay down flat on her sofa and started snoring loudly.

Daphne's sparkling head sank further into her glowing hands. "After my family takes over I'm going to have you all put under anti-Apparition jinxes and Flooed into the sea," she said to no one in particular. "You're all okay with that, right?"

Thunk-thunk, thunk-thunk-thunk, thunk.

Daphne looked up, surprised; that was a Sunshine code-signal -

"I hight someone knocking!" bellowed Mr. Goyle. "Knocking of the door!"

"Let's see what you've got, door!" shouted an older boy near the door, and yanked the door open.

There was a moment of complete surprise.

"I've come to have a word with Miss Greengrass," said the Sunshine General, sounding like she was trying to sound confident. "Could someone please -"

From the look on Hermione's face she had just noticed Daphne sparkling.

And that was when Millicent Bulstrode raced up from the lower dorms and shouted, "Hey, everyone, guess what, now Granger went and beat up Derrick and what's left of his crew, and his father owled him and said that if he didn't -"

Millicent caught sight of Hermione standing in the doorway.

There was a very loud silence.

"Uh," said Daphne. What? said her brain. "Uh, what're you doing here, General?"

"Well," said Hermione Granger with a strange smile on her face, "I've decided it's not fair if mysterious old wizards give some people a chance to be heroes and not others, and also I've read history books and there aren't nearly enough girl heroes in them. So I thought I'd just drop by and see if you wanted to be a hero and why are you glowing like that?"

There was another silence.

"This," said Daphne, "was probably not the best time to ask me that question -"

"I'll take it!" shouted Tracey Davis, leaping off her sofa.

And
