Harry Potter and the Methods of Rationality

I'm assuming control of our body.

The boy took a deep breath, and opened his mouth -

By this point Harry Potter had entirely forgotten the existence of Professor McGonagall, who had been sitting there this whole time undergoing a number of interesting changes of facial expression which Harry had not been looking at because he was distracted. It would have been overly harsh to say that Harry had forgotten her because he did not consider her a PC. It could be more kindly said that Professor McGonagall was not visibly a solution to any of his current problems, and therefore she was not part of the universe.

So Harry, who at this point had a fair amount of adrenaline in his bloodstream, startled and jumped quite visibly when Professor McGonagall, her eyes now blazing with impossible hope and the tears on her cheek half-dried, leapt to her feet and cried, "With me, Mr. Potter!" and, without waiting for a reply, tore down the stairs that led to the bottom platform where waited a chair of dark metal.

It took a moment, but Harry ran after; though it took him longer to reach the bottom, after Professor McGonagall vaulted half the stairs with a strange catlike motion and landed with the astonished-looking Auror trio already pointing their wands at her.

"Miss Granger!" cried Professor McGonagall. "Can you speak yet?"

Much as with Professor McGonagall, there was a certain sense in which it could be said that Harry had forgotten about the existence of Hermione Granger, because Harry had been tilting his neck back to look upward rather than downward, and because he hadn't considered her a solution to any of his current problems. Though it was hardly certain, in fact it wasn't at all probable, that Harry remembering to look at Hermione or think about what she must be feeling, would have helped anything in the slightest.

Harry reached the bottom of the stairs and saw Hermione Granger full on -

Without thinking, without being able to help himself, Harry shut his eyes, but he'd seen.

Her school robes around her neck, soaked all the way through with tears.

The way she'd been looking away from him.

And the eye of memory and sympathy, which could not be shut, which could not look away, knew that Hermione had recounted the worst shame of her life in front of the nobility of magical Britain and Professor McGonagall and Dumbledore and Harry; and then been sentenced to Azkaban where she would be exposed to darkness and cold and all her worst memories until she went mad and died; and then she'd heard that Harry was going to give away all his money and go into debt to save her, and maybe even sacrifice his life

and with the Dementor standing only a few paces behind her

she hadn't said anything...

"Y-yes," whispered the voice of Hermione Granger. "I c-can talk."

Harry opened his eyes again and saw her face, now looking at him. It didn't say anything like what he thought Hermione was feeling, faces couldn't say anything that complicated, all facial muscles could do was contort themselves into knots.

"H-H-Harry, I-I'm so, I'm so -"

"Shut up," Harry suggested.

"s-s-sorry -"

"If you'd never met me on the train you wouldn't be in any trouble right now. So shut up," said Harry Potter.

"Both of you stop being silly," Professor McGonagall said in her firm Scottish accent (it was strange how much that helped). "Mr. Potter, hold out your wand so that Miss Granger's fingers can touch it. Miss Granger, repeat after me. Upon my life and magic -"

Harry did as he was bid, thrusting his wand forward to touch Hermione's fingers; and then Hermione's faltering voice said, "Upon my life and magic -"

"I swear service to the House of Potter -" said Professor McGonagall.

And Hermione, without waiting for any further instructions, said, the words spilling out of her in a rush, "I swear service to the House of Potter, to obey its Master or Mistress, and stand at their right hand, and fight at their command, and follow where they go, until the day I die."

All those words had been blurted out in a desperate gasp before Harry could have thought or said anything, if he'd been mad enough to interrupt.

"Mr. Potter, repeat these words," said Professor McGonagall. "I, Harry, heir and last scion of the Potters, accept your service, until the end of the world and its magic."

Harry took a breath and said, "I, Harry, heir and last scion of the Potters, accept your service, until the end of the world and its magic."

"That's it," said Professor McGonagall. "Well done."

Harry looked up, and saw that the entire Wizengamot, whose existence he'd forgotten, was staring at them.

And then Minerva McGonagall, who was Head of House Gryffindor even if she didn't always act like it, looked up high above at where Lucius Malfoy stood; and she said to him before the entire Wizengamot, "I regret every point I ever gave you in Transfiguration, you vile little worm."

Whatever Lucius was about to say in reply was silenced by a tap of the short rod in Dumbledore's hand. "Ahem!" said the old wizard from his podium of dark stone. "This session has carried on quite considerably, and if it is not dismissed soon, some of us may miss their entire luncheon. The law of this matter is clear. You have already voted on the terms of the bargain, and Lord Malfoy cannot legally decline it. As we have far exceeded our allotted time, I now, in accordance with the last decision of the survivors of the eighty-eighth Wizengamot, adjourn this session."

The old wizard tapped the rod of dark stone three times.
