  Harry didn't care about any of that.

  "Ma-ha-su!"

  A red bolt of energy shot out of his wand and struck the target and the blue sphere once again made the bing which meant the spell had actually worked for him.

  Harry was feeling like a real wizard for the first time since he'd come to Hogwarts. He wished the target would dodge like the little spheres that Ben Kenobi had used for training Luke, but for some reason Professor Quirrell had instead lined up all the students and targets in neat orders which made sure they wouldn't fire on each other.

  So Harry lowered his wand, skipped to the right, snapped up his wand and twisted and shouted "Ma-ha-su!"

  There was a lower-pitched "dong" which meant he'd gotten it almost right.

  Harry put his wand into his pocket, skipped back to the left and drew and fired another red bolt of energy.

  The high-pitched bing which resulted was easily one of the most satisfying sounds he'd heard in his life. Harry wanted to scream in triumph at the top of his lungs. I CAN DO MAGIC! FEAR ME, LAWS OF PHYSICS, I'M COMING TO VIOLATE YOU!

  "Ma-ha-su!" Harry's voice was loud, but hardly noticeable over the steady chant of similar cries from around the classroom platform.

  "Enough," said Professor Quirrell's amplified voice. (It didn't sound loud. It sounded like normal volume, coming from just behind your left shoulder, no matter where you were standing relative to Professor Quirrell.) "I see that all of you have succeeded at least once now." The target-spheres turned red and began to drift up towards the ceiling.

  Professor Quirrell was standing on the raised dais in the center of the platform, leaning slightly on his teacher's desk with one hand.

  "I told you," Professor Quirrell said, "that we would play a game called Who's the Most Dangerous Student in the Classroom. There is one student in this classroom who mastered the Sumerian Simple Strike Hex faster than anyone else -"

  Oh blah blah blah.

  "- and went on to help seven other students. For which she has earned the first seven Quirrell points awarded to your year. Come forth, Hermione Granger. It is time for the next stage of the game."

  Hermione Granger began striding forwards, a mixed look of triumph and apprehension on her face. The Ravenclaws looked on proudly, the Slytherins with glares, and Harry with frank annoyance. Harry had done fine this time. He was probably even in the upper half of the class, now that everyone had been faced with an equally unfamiliar spell and Harry had read all the way through Adalbert Waffling's Magical Theory. And yet Hermione was still doing better.

  Somewhere in the back of his mind was the fear that Hermione was simply smarter than him.

  But for now Harry was going to pin his hopes on the known facts that (a) Hermione had read a lot more than the standard textbooks and (b) Adalbert Waffling was an uninspired sod who'd written Magical Theory to pander to a school board that didn't think much of eleven-year-olds.

  Hermione reached the central dais and stepped up.

  "Hermione Granger mastered a completely unfamiliar spell in two minutes, almost a full minute faster than the next runner-up." Professor Quirrell turned slowly in place to look at all the students watching them. "Could Miss Granger's intelligence make her the most dangerous student in the classroom? Well? What do you think?"

  No one seemed to be thinking anything at the moment. Even Harry wasn't sure what to say.

  "Let's find out, shall we?" said Professor Quirrell. He turned back to Hermione, and gestured toward the wider class. "Select any student you like and cast the Simple Strike Hex on them."

  Hermione froze where she stood.

  "Come now," Professor Quirrell said smoothly. "You have cast this spell perfectly over fifty times. It is not permanently harmful or even all that painful. It hurts as much as a hard punch and lasts only a few seconds." Professor Quirrell's voice grew harder. "This is a direct order from your professor, Miss Granger. Choose a target and fire a Simple Strike Hex."

  Hermione's face was screwed up in horror and her wand was trembling in her hand. Harry's own fingers were clenching his own wand hard in sympathy. Even though he could see what Professor Quirrell was trying to do. Even though he could see the point Professor Quirrell was trying to make.

  "If you do not raise your wand and fire, Miss Granger, you will lose a Quirrell point."

  Harry stared at Hermione, willing her to look in his direction. His right hand was softly tapping his own chest. Pick me, I'm not afraid...

  Hermione's wand twitched in her hand; then her face relaxed, and she lowered her wand to her side.

  "No," said Hermione Granger.

  Her voice was calm, and even though it wasn't loud, everyone heard it in the silence.

  "Then I must deduct one point from you," said Professor Quirrell. "This is a test, and you have failed it."

  That reached her. Harry could see it. But she kept her shoulders straight.

  Professor Quirrell's voice was sympathetic and seemed to fill the whole room. "Knowing things isn't always enough, Miss Granger. If you cannot give and receive violence on the order of stubbing your toe, then you cannot defend yourself and you will not pass Defence. Please rejoin your classmates."

  Hermione walked back towards the Ravenclaw cluster. Her face looked peaceful and Harry, for some odd reason, wanted to start clapping. Even though Professor Quirrell had been right.

  "So," Professor Quirrell said. "It becomes clear that Hermione Granger is not the most dangerous student in the classroom. Who do you think might actually be the most dangerous person here? - besides me, of course."

  Without even thinking, Harry turned to look at the Slytherin contingent.

  "Draco, of the Noble and Most Ancient House of Malfoy," said Professor Quirrell. "It seems that many of your fellow pupils are looking in your direction. Come forth, if you would."

  Draco did so, walking with a certain pride in his bearing. He stepped onto the dais and looked up at Professor Quirrell with a smile.

  "Mr. Malfoy," Professor Quirrell said. "Fire."

  Harry would have tried to stop it if there'd been time but in one smooth motion Draco spun on the Ravenclaw contingent and raised his wand and said "Mahasu!" like it was all one syllable and Hermione was saying "Ow!" and that was that.

  "Well struck," said Professor Quirrell. "Two Quirrell points to you. But tell me, why did you target Miss Granger?"

  There was a pause.

  Finally Draco said, "Because she stood out the most."

  Professor Quirrell's lips turned up in a thin smile. "And that is the true reason why Draco Malfoy is dangerous. Had he selected any other, that child would more likely resent being singled out, and Mr. Malfoy would more probably make an enemy. And while Mr. Malfoy might have given some other justification for selecting her, that would have served him no purpose save to alienate some of you, while others are already cheering him whether he says anything or not. Which is to say that Mr. Malfoy is dangerous because he knows who to strike and who not to strike, how to make allies and avoid making enemies. Two more Quirrell points to you, Mr. Malfoy. And as you have demonstrated an exemplary virtue of Slytherin, I think that Salazar's House has earned a point as well. You may rejoin your friends."

  Draco bowed slightly and walked back to the Slytherin contingent. Some clapping started from the green-trimmed robes, but Professor Quirrell made a cutting gesture and silence fell again.

  "It might seem that our game is done," said Professor Quirrell. "And yet there is a single student in this classroom who is more dangerous than the scion of Malfoy."

  And now for some reason there seemed to be an awful lot of people looking at...

  "Harry Potter. Come forth."

  This did not bode well.

  Harry reluctantly walked towards where Professor Quirrell stood on his raised dais, still leaning slightly against his teacher's desk.

  The nervousness of being put into the spotlight seemed to be sharpening Harry's wits as he approached the dais, and his mind was ruffling
through possibilities for what Professor Quirrell might think could demonstrate Harry's dangerousness. Would he be asked to cast a spell? To defeat a Dark Lord?

  Demonstrate his supposed immunity to the Killing Curse? Surely Professor Quirrell was too smart for that...

  Harry stopped well short of the dais, and Professor Quirrell didn't ask him to come any closer.

  "The irony is," said Professor Quirrell, "you all looked at the right person for entirely the wrong reasons. You are thinking," Professor Quirrell's lips twisted, "that Harry Potter has defeated the Dark Lord, and so must be very dangerous. Bah. He was one year old. Whatever quirk of fate killed the Dark Lord likely had little to do with Mr. Potter's abilities as a fighter. But after I heard rumors of one Ravenclaw facing down five older Slytherins, I interviewed several eyewitnesses and came to the conclusion that Harry Potter would be my most dangerous student."

  A jolt of adrenaline poured into Harry's system, making him stand up straighter. He didn't know what conclusion Professor Quirrell had come to, but that couldn't be good.

  "Ah, Professor Quirrell -" Harry started to say.

  Professor Quirrell looked amused. "You're thinking that I've come up with a wrong answer, aren't you, Mr. Potter? You will learn to expect better of me." Professor Quirrell straightened from where he had leaned on the desk. "Mr. Potter, all things have their accustomed uses. Give me ten unaccustomed uses of objects in this room for combat!"

  For a moment Harry was rendered speechless by the sheer, raw shock of having been understood.

  And then the ideas started to pour out.

  "There are desks which are heavy enough to be fatal if dropped from a great height. There are chairs with metal legs that could impale someone if driven hard enough. The air in this classroom would be deadly by its absence, since people die in vacuum, and it can serve as a carrier for poison gases."

  Harry had to stop briefly for breath, and into that pause Professor Quirrell said:

  "That's three. You need ten. The rest of the class thinks that you've already used up the whole contents of the classroom."

  "Ha! The floor can be removed to create a spike pit to fall into, the ceiling can be collapsed on someone, the walls can serve as raw material for Transfiguration into any number of deadly things - knives, say."

  "That's six. But surely you're scraping the bottom of the barrel now?"

  "I haven't even started! Just look at all the people! Having a Gryffindor attack the enemy is an ordinary use, of course -"

  "I will not count that one."

  "- but their blood can also be used to drown someone. Ravenclaws are known for their brains, but their internal organs could be sold on the black market for enough money to hire an assassin. Slytherins aren't just useful as assassins, they can also be thrown at sufficient velocity to crush an enemy. And Hufflepuffs, in addition to being hard workers, also contain bones that can be removed, sharpened, and used to stab someone."

  By now the rest of the class was staring at Harry in some horror. Even the Slytherins looked shocked.

  "That's ten, though I'm being generous in counting the Ravenclaw one. Now, for extra credit, one Quirrell point for each use of objects in this room which you have not yet named." Professor Quirrell favored Harry with a companionable smile. "The rest of your class thinks you are in trouble now, since you've named everything except the targets and you have no idea what may be done with those."

  "Bah! I've named all the people, but not my robes, which can be used to suffocate an enemy if wrapped around their head enough times, or Hermione Granger's robes, which can be torn into strips and tied into a rope and used to hang someone, or Draco Malfoy's robes, which can be used to start a fire -"

  "Three points," said Professor Quirrell, "no more clothing now."

  "My wand can be pushed into an enemy's brain through their eye socket" and someone made a horrified, strangling sound.

  "Four points, no more wands."

  "My wristwatch could suffocate someone if jammed down their throat -"

  "Five points, and enough."

  "Hmph," Harry said. "Ten Quirrell points to one House point, right? You should have let me keep going until I'd won the House Cup, I haven't even started yet on the unaccustomed uses of everything I've got in my pockets" or the mokeskin pouch itself and he couldn't talk about the Time-Turner or the invisibility cloak but there had to be something he could say about those red spheres...

  "Enough, Mr. Potter. Well, do you all think you understand what makes Mr. Potter the most dangerous student in the classroom?"

  There was a low murmur of assent.

  "Say it out loud, please. Terry Boot, what makes your dorm-mate dangerous?"

  "Ah... um... he's creative?"

  "Wrong!" bellowed Professor Quirrell, and his fist came down sharply on his desk with an amplified sound that made everyone jump. "All of Mr. Potter's ideas were worse than useless!"

  Harry started in surprise.

  "Remove the floor to create a spike trap? Ridiculous! In combat you do not have that sort of preparation time and if you did there would be a hundred better uses! Transfigure material from the walls? Mr. Potter cannot perform Transfiguration! Mr. Potter had exactly one idea which he could use immediately, right now, without extensive preparation or a cooperative enemy or magic he does not know. That idea was to jam his wand through his enemy's eye socket. Which would be more likely to break his wand than kill his opponent! In short, Mr. Potter, I'm afraid that your proposals were uniformly awful."

  "What?" Harry said indignantly. "You asked for unusual ideas, not practical ones! I was thinking outside the box! How would you use something in this classroom to kill someone?"

  Professor Quirrell's expression was disapproving, but there were smile crinkles around his eyes. "Mr. Potter, I never said you were to kill. There is a time and a place for taking your enemy alive, and inside a Hogwarts classroom is usually one of those places. But to answer your question, hit them on the neck with the edge of a chair."

  There was some laughter from the Slytherins, but they were laughing with Harry, not at him.

  Everyone else was looking rather horrified.

  "But Mr. Potter has now demonstrated why he is the most dangerous student in the classroom. I asked for unaccustomed uses of items in this room for combat. Mr. Potter could have suggested using a desk to block a curse, or using a chair to trip an oncoming enemy, or wrapping cloth around his arm to create an improvised shield. Instead, every single use that Mr. Potter named was offensive rather than defensive, and either fatal or potentially fatal."

  What? Wait, that couldn't be true... Harry had a sudden sense of vertigo as he tried to remember what exactly he'd suggested, surely there had to be a counterexample...

  "And that," Professor Quirrell said, "is why Mr. Potter's ideas were so strange and useless - because he had to reach far into the impractical in order to meet his standard of killing the enemy. To him, any idea which fell short of that was not worth considering. This reflects a quality that we might call intent to kill. I have it. Harry Potter has it, which is how he could stare down five older Slytherins. Draco Malfoy does not have it, not yet. Mr. Malfoy would hardly shrink from talk of ordinary murder, but even he was shocked - yes you were Mr. Malfoy, I was watching your face - when Mr. Potter described how to use his classmates' bodies as raw material. There are censors inside your mind which make you flinch away from thoughts like that. Mr. Potter thinks purely of killing the enemy, he will grasp at any means to do so, he does not flinch, his censors are off. Even though his youthful genius is so undisciplined and impractical as to be useless, his intent to kill makes Harry Potter the Most Dangerous Student in the Classroom. One final point to him - no, let us make that a point to Ravenclaw - for this indispensable requisite of a true fighting wizard."

  Harry's mouth gaped open in speechless shock as he searched frantically for something to say to this. That is so completely not what I am about!

  But he could see that the other s
tudents were starting to believe it. Harry's mind was flipping through possible denials and not finding anything that could stand up against the authoritative voice of Professor Quirrell. The best Harry had come up with was "I'm not a psychopath, I'm just very creative" and that sounded kind of ominous. He needed to say something unexpected, something that would make people stop and reconsider -

  "And now," Professor Quirrell said. "Mr. Potter. Fire."

  Nothing happened, of course.

  "Ah, well," said Professor Quirrell. He sighed. "I suppose we must all start somewhere. Mr. Potter, select any student you please for a Simple Strike Hex. You will do so before I dismiss your class for the day. If you do not, I will begin deducting House points, and I will keep on deducting them until you do."

  Harry carefully raised his wand. He had to do that much, or Professor Quirrell might start deducting House points right away.

  Slowly, as though on a roasting platter, Harry turned to face the Slytherins.

  And Harry's eyes met Draco's.

  Draco Malfoy didn't look the slightest bit afraid. The blonde-haired boy wasn't giving any visible sign of assent such as Harry had given Hermione, but then he could hardly be expected to do so. The other Slytherins would think that rather odd.

  "Why the hesitation?" said Professor Quirrell. "Surely there's only one obvious choice."

  "Yes," Harry said. "Only one obvious choice."

  Harry twisted the wand and said "Ma-ha-su!"

  There was complete silence in the classroom.

  Harry shook his left arm, trying to get rid of the lingering sting.

  There was more silence.

  Finally Professor Quirrell sighed. "Yes, quite ingenious, but there was a lesson to be taught and you dodged it. One point from Ravenclaw for showing off your own cleverness at the expense of the actual goal. Class dismissed."

  And before anyone else could say anything, Harry sang out:

  "Just kidding! RAVENCLAW!"

  There was silence for a brief moment after that, a sound of people thinking, and then the murmurs started and rapidly rose to a roar of conversation.

  Harry turned towards Professor Quirrell, the two of them needed to talk -
