Tom Riddle.

The words seemed to echo inside Harry's head, sparking resonances that as quickly died away, broken patterns trying to complete themselves and failing.

Tom Riddle is a

Tom Riddle was the

Riddle

There were other priorities occupying Harry's attention.

Professor Quirrell was pointing a gun at him.

And for some reason Lord Voldemort hadn't fired it yet.

Harry's voice came out in more of a croak. "What is it that you want from me?"

"Your death," said Professor Quirrell, "is clearly not what I am about to say, since I have had plenty of time to kill you if I wished. The fateful battle between Lord Voldemort and the Boy-Who-Lived is a figment of Dumbledore's imagination. I know where to find your family's house in Oxford, and I am familiar with the concept of sniper rifles. You would have died before you ever touched a wand. I hope this is clear to you, Tom?"

"Crystal," Harry whispered. His body was still shaking, running programs more suited to fleeing a tiger than casting delicate spells or thinking. But Harry could think of one thing the person pointing a gun at him obviously wanted him to do, a question that person was waiting for him to ask, and Harry did so. "Why are you calling me Tom?"

Professor Quirrell regarded him steadily. "Why am I calling you Tom? Answer. Your intellect is not everything I hoped for, but it should suffice for this."

Harry's mouth seemed to know the answer before his brain could manage to focus on the question. "Tom Riddle is your name. Our name. That's who Lord Voldemort is, or was, or - something."

Professor Quirrell nodded. "Better. You have already vanquished the Dark Lord, the one and only time that you will ever do so. I have already destroyed all but a remnant of Harry Potter, eliminating the difference between our spirits and enabling us to reside in the same world. Now that it is clear to you that the battle between us is a lie, you might act sensibly to advance your own interests. Or you might not." The gun jabbed slightly forward, causing prickles of sweat to appear on Harry's forehead. "Drop your wand. Now."

Harry dropped it.

"Step away from the wand," said Professor Quirrell.

Harry obeyed.

"Reach toward your neck," said Professor Quirrell, "and remove your Time-Turner, touching it by the chain only. Place the Time-Turner on the ground, then step away from it as well."

This also Harry did. Even in his state of shock, his mind still looked for a way to spin the Time-Turner in the process, a sudden move that would win; but Harry knew that Professor Quirrell would already be imagining himself in Harry's position, looking for the same possible opportunities.

"Remove your pouch and place it also on the ground, then step away."

Harry did this.

"Very good," said the Defense Professor. "Now. It is time for me to obtain the Philosopher's Stone. I mean to bring along these four first-years here, suitably Obliviated of their most recent memories so that they still recall their original purpose. Snape I shall control and set to guard this door. After this day's work is done, I intend to kill Snape for the betrayals he has offered my other identity. The three heir-children I shall take with me afterwards, to shape their future loyalties. You should also know this, I have taken hostages as insurance in case of a fight with the Headmaster. I have already set in motion a spell that will kill hundreds of Hogwarts students, and it can't be stopped if I am killed or otherwise restrained. I can and will stop that spell using the Stone, if I obtain it successfully. Hogwarts students are a valuable resource, not to be wasted lightly. If I am interrupted before then, or if I choose not to stop the spell, hundreds of students will die." Professor Quirrell's voice was still mild. "Do you yet perceive any interests you have at stake, boy? I would smile to hear you say 'no', but that is too much to hope."

"I'd like," Harry managed to say, through the horror, and the heartbreak, and the knives slicing away at an emotional connection that hurt like living flesh as it was cut, "for you not to do those things, Professor." Why, Professor Quirrell, why, why did it have to turn out like this, I don't, I don't, I don't want this to be happening…

"Very well," Professor Quirrell said. "I grant you permission to offer me something I want." The gun gestured invitingly.

Some part of Harry's mind scrabbled frantically, looking for something, anything that might be of more value to Lord Voldemort or Professor Quirrell than child hostages or Severus's death.

Another part of him, the part that had never stopped thinking, already knew his answer.

"You already have an idea for what you want from me," Harry said, through the sickness and the bleeding wounds in his soul. "What is it?"

"Your help in obtaining the Philosopher's Stone."

Harry swallowed. He couldn't stop his eyes from going to the gun, then back up at Professor Quirrell's face. He was aware that the hero in a storybook was supposed to say 'No', but now that he was actually in a situation like this, saying 'No' didn't seem to make sense.

"I am disappointed that you need to think about this," said Professor Quirrell. "It is straightforward that you should obey me for now, since I hold every advantage over you. I have taught you better than this; in this situation you should certainly pretend to lose. You can expect to gain nothing by resisting, except pain. You should have calculated that it was better to answer sooner, and not earn my distrust." Professor Quirrell's eyes studied him curiously. "I hope Dumbledore hasn't filled your ears with nonsense about noble defiance? You should be able to see why that sort of strategy would be entirely pointless, and that I could easily make it seem morally worse than submission, should you nonetheless resort to it. I would prefer not to have to demonstrate how."

Harry took a deep breath, several of them. Whatever part of him kept on running on full automatic was screaming at the remainder of his mind that it could not afford to stay in shock. Shocks were of finite duration, neurons kept firing regardless, the only reason Harry's mind would shut down while his brain kept running was if Harry's self-model believed his mind would shut down -

"I don't mean to try your patience," Harry said. His voice was cracking. That was good. Sounding like he was still in shock meant that Lord Voldemort might give him more time. "But if Lord Voldemort had a reputation for keeping his bargains, I don't know about it."

"An obvious concern," Professor Quirrell said. "There is a simple answer, and I would have enforced it upon you in any case. Ssnakes can't lie. And since I have a tremendous distaste for stupidity, I suggest you do not say anything like 'What do you mean?' You are smarter than that, and I do not have time for such conversations as ordinary people inflict on one another."

Harry swallowed. Snakes can't lie. "Two pluss two equalss four." Harry had tried to say that two plus two equalled three, and the word four had slipped out instead.

"Good. When Salazar Slytherin invoked the Parselmouth curse upon himself and all his children, his true plan was to ensure his descendants could trust one another's words, whatever plots they wove against outsiders." Professor Quirrell had adopted his lecturing pose from Battle Magic, like someone putting on a well-worn mask, but the gun remained pointed in his hand. "Occlumency cannot fool the Parselmouth curse as it can fool Veritaserum, and you may put that to the trial also. Now listen well. Come with me, promisse your besst aid in getting Sstone, and I sshall leave thesse children behind unharmed. Hosstagess are real, hundredss of sstudentss die tonight unlesss I sstop eventss already sset in motion. Will sspare hosstagess if I obtain Sstone ssuccessfully. And mark also this, mark it well: I cannot be truly sslain by any means known to me, and lossing Sstone will not sstop me from returning, nor sspare you or yourss my wrath sshould you be the causse of that. I do hope you would cooperate with this venture, since you stand only to gain from it. But I also credit your ability to annoy me by meddling in my plans, and suggest you avoid doing so."

"You said," Harry's voice was strange in his own ears, "that the Philosopher's Stone had different powers from what legend said. You said that to me in Parseltongue. Tell me what the Stone really does, before I agree to help you get it."

"Ah," said Professor Quirrell, and smiled. "You are thinking. That is better, and as a reward I shall offer you a further incentive for cooperation. Eternal life and youth, the creation of gold and silver. Suppose these are true benefits of holding the Stone. Tell me, boy. What is the Stone's power?"

It might have been the adrenaline still in him, being actually useful for his brain for once. It might have been the power of being told that an answer existed, and that the evidence wasn't a lie. "It can make Transfigurations permanent."

Then Harry stopped, as he heard what his own mouth had just said.

"Correct," hissed Professor Quirrell. "Thus, whoever holds the Philosopher's Stone is able to perform human Transfiguration."

Harry's torn mind was knocked about yet again, as he realized what further incentive would be offered him.

"You stole Miss Granger's remains and Transfigured them into some innocuous-appearing target," said Professor Quirrell. "A Transfigured target that you must keep somewhere about your own person, in order to sustain the Transfiguration. Ah, I see your eyes going to that ring upon your hand, but of course Miss Granger would not be the little jewel set into the ring, would it? That would be too obvious. No, I expect you Transfigured Granger's remains into the ring itself, letting the aura of the Transfigured jewel mask the magic in the Transfigured ring."

"Yes," Harry said, forcing out the word. It was a lie, for once, and Harry's glance had been deliberate. Harry had expected someone to challenge him on the steel ring, he'd tried to provoke that challenge so he could prove to be innocent yet again, though nobody had taken him up on it - maybe Dumbledore had just sensed that the steel by itself wasn't magical.

"Fine and good," said Professor Quirrell. "Now come with me, help me to obtain the Stone, and I will resurrect Hermione Granger on your behalf. Her death has had unfortunate effects on you, and I would not mind undoing them. That, as I understand you, is your greatest desire. I have done you many kindnesses, and I would not mind doing you this one more." A blank-eyed Professor Sprout had now risen from the ground and was pointing her own wand at Harry. "Help me obtain Sstone of Transsfiguration, and I sshall try my hardesst to ressurrect your girl-child friend to true and lassting life."

Even then.

Even then, with all the world upturned, with shock after shock, even then Harry's brain did not stop being a brain, or completing the patterns its circuits had been wired to complete.

Harry knew that this was too good an offer to make to someone at whom you were pointing a gun.

Unless you desperately needed their help to get the Philosopher's Stone out of the magic mirror.

And there wasn't any time left to plan, only the thought that, if Professor Quirrell really was going this far to get his help - what Harry wanted was to demand Professor Quirrell promise not to kill anyone in the future in exchange for his help now, but Harry had a strong sense that Professor Quirrell would reply 'Don't be ridiculous' and there wasn't time for ordinary conversation Harry had to guess the highest safe request in advance -

And this was when his Ravenclaw side spoke up, and astonished even Harry himself.

We are not doing this.

What? Said Hufflepuff.

We were about to ask for the lives of Hogwarts students in return for our help, or something similar, weren't we? How many people do we need to indirectly kill before we will actually start to clearly evaluate the real consequences of our actions? Said Ravenclaw.

Are you insane? In what way is saving Hogwarts students killing people? That's too much even by my standards, said Slytherin.

This is not about Hogwarts students, or even Britain, answered Ravenclaw. Remember that time we re-evaluated how dangerous Lord Voldemort was? Now do it again, except take into account this is Professor Quirrell we are talking about. How did we put it? A Dark Rationalist isn't a "threat", they are an extinction event? If Lord Voldemort wanted, he could take over the whole world tomorrow, whatever his reasons for not doing so earlier. We aren't deciding whether dark lord number 498 gets magical artifact of dread power number 38, we are deciding who is going to pretty much single-handedly dictate the future of the whole world.

So what are you suggesting? said Slytherin. We throw ourselves at him, get shot and die? That will stop him from taking over the world for sure.

Dumbledore, whatever his other faults, isn't a complete idiot, answered Ravenclaw, he has probably set protections around the stone sufficiently dangerous to threaten even Lord Voldemort. This is why the Professor is pointing the gun at you - he needs your help, because he expects a higher chance of success with your help than without. If his utility function is sufficiently incompatible with yours, like if he wants to blow the earth up, then decreasing his chance of successfully obtaining the stone is worth more than the lives of all Hogwarts students taken together.

What? said Hufflepuff. You can't trade human lives like that-

Ravenclaw just flashed an image of Hermione's still body, with "five billion times this" written above it.

NO! internally screamed all of Harry.

Then start multiplying like the consequentialist you claim to be, said Ravenclaw, unless you know what kind of future Quirinus Quirrell is going to bring about, you cannot in good conscience help him become more powerful. Furthermore, pretty much everything else is overshadowed by the five billion humans at stake here, so almost nothing but his terminal values actually matters.

And how do you expect to find those out? said Slytherin. If you ask, he can always ...just...lie...

Professor Quirrell's eyes narrowed, his lips parted -

"Before I can decide to help you," blurted out Harry, "I need to know what are your terminal goals, Professor."

Professor Quirrell rolled his eyes at this. "While I can appreciate the spirit of not giving up, that is far too blatant even given the pressure you are under. I will not talk about my future plans. Ask something else."

"Not plans, goals. Like..."-Harry struggled to come up with an explanation for "utility function" - "If we were playing chess then your goals could be to win the game, or to teach the other player to play, or something else, while your plans would be the moves you intended to take. Terminal goals are ones that are worth it in and of themselves, and not because they let you achieve some other goal."

Professor Quirrell seemed annoyed. "Are you just wasting time, boy? You can guess at my goals well enough, then. Why are you asking? Answer in parseltongue."

"Wass not wassting time. If you are the ssort of persson who would want to desstroy the world, or ensslave all humanss, or ssend humanity back to the dark agess, I can not, will not help you. Besst to gamble on Sschoolmasster'ss defencess being too much for you."

"What part of pretending to lose didn't you learn? If those were my goals, you should still have agreed to help, to best control my actions in the future."

"No point. Would not have been able to sswear regardlesss, if I wassn't sssure, ssso might as well assk directly."

Professor Quirrell sighed, and hissed. "I do not want to die. I want to ssspend my life enjoying myssself without being ssurrounded by idiotsss. Do not want to desstroy the world - thiss isss where I keep my ssstuff, are you a fool boy? Why would I ssseek to dessstroy it? Do not care for humanity one way or another, asss long asss it doessn't interfere with other desssiress. Now are you done wassting time? Make your decisssion now."

"In return for me helping you," Harry's mouth said, "I want your promise that you do not plan to turn on me when this is over. I want answers, the truth about everything that's been going on this whole time and everything you know about my nature."

The pale blue eyes regarded him dispassionately.

I really think we could have thought of something better to ask for than that, said Harry's Slytherin side. But I suppose we were legitimately out of time, and whatever we need to do next, answers will help.

Harry wasn't listening to that voice right now. Cold chills were still going down his spine from hearing the words that had just come out of his lips, addressed to the man with the gun.

"That is your final condition for helping me to obtain the Stone?" said Professor Quirrell.

Harry nodded, unable to form words.

"Agreed," hissed Professor Quirrell. "I do not intend to threaten your life or magic in future, sso long ass you do not become a threat to my life or magic. Help me, and you sshall have ansswerss to your quesstions, sso long ass they are about passt eventss, and not my planss for the future. Now promisse that you will not attempt to warn againsst me or esscape. Promisse to put forth your own besst efforts toward helping me to obtain the Sstone. And your girl-child friend sshall be revived by me, to true life and health; nor sshall me or mine ever sseek to harm her." A twisted smile. "Promisse, boy, and the bargain will be sstruck."

"I promise," whispered Harry.

WHAT? screamed other parts of his mind.

Um, he's still pointing a gun at us, pointed out Slytherin. We confirmed he wasn't going to wipe away humanity with decent certainty, and so we don't actually have much of a choice in following our personal objectives, we're just getting as much mileage out of this as possible.

You bastard, said Hufflepuff. Do you think this is what Hermione would have wanted? This is Lord Voldemort we're talking about, do we even know how many people he's killed, and will kill? You didn't even ask for the safety of your friends!

Both of those things are irrelevant, said Ravenclaw, Voldemort clearly does not care for your friends. Asking for their safety would just sacrifice your, currently extremely limited, political capital with him.

Political capital? screamed Hufflepuff, POLITICAL CAPITAL? Do you want to make peace with him, after all he has done?

We probably should, said Slytherin. I mean, suppose that we can get to our win state-conquering the world, stopping death, and so on- just two weeks earlier if we make peace with Quirrell. Either because he directly assists us with his magical lore and intelligence or because we do not waste resources on trying to fight him. The natural death rate in the world is what, around two people per second? If Quirrell killed five people per hour, every hour, and didn't sleep it'd take him sixty years just to break even with the number of people you'd save by agreeing to a truce with him. Now, two weeks is a lower estimate, and from what we know of him he doesn't kill indiscriminately. He would probably only resort to murder if it was convenient or if the person personally offended him, so the actual rates would be significantly lower, and we could decrease them even more. Do you think we wouldn't find a way to keep him away from idiots in sixty years? Or solve the problem permanently, for that matter?

Professor Quirrell regarded him steadily. "Repeat the full promise in Parseltongue, boy."

"I sshall help you obtain the Sstone... I cannot promisse I will usse my besst efforts, my heart will not be in it, I fear. I intend to try. Sshall not do anything I think will annoy you to no good end. Sshall call no help if I expect them to be killed by you or for hosstagess to die. I'm ssorry, teacher, but it iss besst I can do." Harry's mind was settling, composing itself, as the decision was made. He would stay with Professor Quirrell, go with him to get the Stone, and... and... and Harry didn't know, except that he'd go on thinking. It seemed unlikely that he would die, given the oath professor made.

"You actually are sorry about that?" Professor Quirrell looked amused. "I suppose it shall have to do. Then keep two other things in mind: I have plan to sstop even sschoolmasster, if he appearss before uss. And also this: I will occasionally ask you to say in Parseltongue whether you have betrayed me. The bargain is sstruck."

After that, Professor Sprout picked up Harry's wand, and wrapped it in shimmering cloth; then she placed it on the floor, and again pointed her wand at Harry. Only then did Professor Quirrell lower his gun, which seemed to disappear into his hand, and pick up Harry's wrapped wand, tucking it into his robes.

The True Cloak of Invisibility was removed from the sleeping form of Lesath Lestrange, and Professor Quirrell took the Cloak, as well as Harry's pouch and Time-Turner.

Then Professor Quirrell cast a mass Obliviation followed by the mass version of the False Memory Charm, the one that just had the subject fill in the blanks using their own suggestibility, on all the students present. Afterwards Professor Sprout floated away the sleeping children, now wearing an expression that seemed annoyed and preoccupied, as if they'd been in some Herbology accident.

Professor Quirrell then turned back to where the Potions Master lay sprawled, bent over and placed his wand on Professor Snape's forehead. "Alienis nervus mobile lignum."

The Defense Professor stepped back, and began to move his left fingers in the air as though manipulating a puppet on strings.

Professor Snape pushed himself up from the ground by smooth motions, and stood once more before the corridor door.

"Alohomora," Professor Quirrell said, pointing his wand at the forbidden door. The Defense Professor looked rather amused. "Would you do the honors, boy?"

Harry swallowed. He was once again having second thoughts, and third thoughts.

He composed himself. Numbers didn't lie. Whatever hesitation he was feeling was coming from his emotional side, that deontological mode that the human brain fell into all too easily. The consequences of his choices seemed clear enough, which was the important thing.

Harry laid his hand on the door-knocker, and took several deep breaths, again composing his mind as best he could. Go through with it, don't get shot, be there to optimize events, be there to watch for opportunities and stay capable of taking them. It wasn't a great choice, but all the other ones seemed significantly worse. Just think, if he was just a little less sane he might have actually considered attempting to kill Voldemort, and would have lost all the protection the oath the Professor gave afforded him.

Harry pushed open the forbidden door, and stepped through.
