"Open", Harry said to the Gargoyle in front of Albus Dumbledore's office. "Open now, or I will be making it very, very uncomfortable for you."
"No?" Harry nodded. He snapped every magical string attached to the Gargoyle and it tumbled to the ground, completely bereft of the Magic that gave it mild sentience and bodyguard capabilities.
He knocked on Dumbledore's door.
"Truly, your knowledge of Magic is formidable, Harry", came a voice from behind the door.
Harry knew that the spell that Dumbledore had cast had been something to the effect of echolocation.
"Do you know who this is, Professor?"
"No, I must confess to have not experienced the specific magical signature before. It doesn't seem entirely human, in fact, it seems sort of like- Is it an Animagus?"
"This is Peter Pettigrew." Dumbledore jumped to his feet.
"He was a rat Animagus, a pet of Ronald Weasley for many, many years. I doubt Weasley knew about it. The man coming up the stairs is Sirius Black."
Dumbledore's wand appeared in his hand very, very quickly. Harry noticed that there was something very peculiar about it - a sort of primordial magic that he had only felt from the Fae. He filed it away for later consideration.
"He's innocent, of all his crimes, even the perceived one."
"No, Harry, you don't understand! Your parents were hidden under the Fidelius - he was the only one who could have-"
"Professor, were you there when my parents gave their Secret away?"
"They made an oath to-"
"A magical oath?" Harry wondered.
"No, but despite this, I can not allow Sirius Black to run around unfettered until this mystery is solved." A spell flew from Dumbledore's wand, but Harry unmade it, pulling on the strands until they collapsed. In a real duel, it would be impossible to do it - there were too many spells that activated immediately, like the Elemental series he was so fond of, and it was difficult to do it under pressure, but the results of long practice were stunning.
"What?" Dumbledore stared at his completely ineffective spell, as Sirius carefully laid his stolen or found wand on the ground and held his hands up.
"Do you have a way to guarantee the truth without destroying his mind?" Harry wondered.
"Yes, I have Veritaserum."
Harry was taken aback. Veritaserum, according to every reference book he had come across, was prohibitively expensive, and nearabouts impossible to brew. "I had no idea that Snape was that skilled."
"In truth, his Potions mastery is a three-part merit - he has achievements in potions creation, potions improvement and potions comparison. Veritaserum is not quite as difficult for a man who knows everything about how potions are made. Professor Snape is possibly the most qualified potions master in England, my boy."
Harry filed that away for further consideration as well. "Now, should we dose him up, or should we wait for clearance from the Ministry?"
"Bureaucracy is the enemy of justice, my boy." Dumbledore's eyes twinkled madly as he pulled out a vial and added three drops to an unmoving Peter Pettigrew's tongue, forcing his mouth open with a spell. He pushed the man's mouth shut, held his nose, and undid Harry's Petrification charm.
Pettigrew thrashed for a moment, and was then still, his eyes adopting a glassy sheen.
"What is your name?" Dumbledore asked.
"Peter Pettigrew."
"Were you once part of a group known as the Marauders during your schooling?" Sirius asked.
"Yes."
"Do you know who I am?" Harry Potter asked Peter.
"Yes."
"Were you the secret keeper for my parents?" Harry continued.
"Yes."
"Were you under a sort of coercion when you gave away the Secret?" Harry asked.
"Yes."
"Will you willingly give longer responses?" Sirius growled.
"No."
"Are you loyal to Tom Riddle, who calls himself Voldemort?" Harry asked. Dumbledore looked at him sharply.
"Yes."
"When did you join the Death Eaters?" Sirius asked.
"End of Seventh Year."
"Who invited you to the Death Eaters?" Sirius continued.
"Severus Snape."
"Why did you join the Death Eaters?" Harry wondered.
Pettigrew seemed to be fighting the question. Sirius stared at the man for a moment, then rephrased the question. "Did you join the Death Eaters for money or power?"
"Power", Peter ground out.
"Is it wearing off, Professor?" Harry asked.
"No, it isn't. However, he seems to have a stronger will than I thought previously." Dumbledore looked from Sirius to Peter, the former who was asking whether Peter had ever been loyal to his friends.
"Can you up the dosage, sir?"
"No, I believe that would actually liquefy his mind, my boy."
"How dare you!" Sirius shouted. "We gave you everything! We took you in when you were bullied, and when-"
"Sirius, that's enough. We know beyond a doubt that he betrayed my parents." Harry turned to Dumbledore, "is there a way we can cripple him semi-permanently? Something that could only be reversed with a specific antidote, or something that only wears off after a certain amount of time, so he doesn't escape?"
"Well, Severus had a batch of paralysis potion he had been complaining about never having a use for. It'll last a month if used on an unwilling victim, longer if he wants to stay paralysed, and will not kill him."
Dumbledore walked over to his fireplace and threw a handful of floo powder into it. The fireplace flared green. "Severus!" he called out.
Several moments later, a surly face could be seen in the fireplace. "What could you possibly need at this hour, Albus?" He then noticed Harry and two unidentified men in the room, one of which was slumped over and drooling, the other with a rather feral look on his face.
"I have managed to find a use for your stock of paralysis potion, Severus. Would you please bring it to an old man?"
"Immediately", Snape promised, and his face disappeared from the fireplace.
There was silence for a moment.
"Harry, I must admit to being curious as to how you stopped me from Stunning Sirius. That particular variant has the effect of piercing shield charms quite easily."
Harry nodded, and nearly crowed in success. He had wanted to view H-class Shieldbreaking Dueling Charms in action for quite a while, and believed that he would be able to perform all of them now that he had seen them. "I'm not sure. It was pretty raw - I didn't want you to damage Sirius, because I thought he was innocent, and somehow, my magic flared, and I felt a bit lightheaded."
"Very, very specific accidental magic indeed. I'll tell Filius that you're ready for Wandless training. The benefits of Wandless magic are many, despite the fact that there is little to no finesse in the cas- There you are, Severus."
Snape walked into the room a moment later.
"Hello Albus", he said, carrying a vial of what could only be Paralysis potion. It was the color of brackish blood, and looked wholly unpleasant. "Who are they?" he hissed.
"I'm surprised you don't recognize me, Snivellus", Sirius sneered.
"You!" Snape roared, a spell rushing from his wand in less than a second. Harry admired his draw, but took apart the rather nasty Bonecrushing Hex even as Dumbledore used a Class-P Bunker Shield, capable of stopping anything from muggle missiles to nearly twenty Dark curses at once. Harry smiled. He was learning quite a lot from this excursion.
"That's Peter Pettigrew, Professor", Harry said, kicking the heap of bones. "He betrayed... my mother... to Voldemort."
Dumbledore didn't notice Harry's specific usage, but Snape did, and was now glaring at the fleshbag with undisguised contempt.
Snape knelt, grasped Peter by the jaw very, very firmly and pried it open, then dumped the contents of his vial into the man's mouth, causing the Rat Animagus to spasm, then go still.
"He should be out of it for a month or more, depending on his will to move. Send him to Azkaban." He gave Sirius a curt glare, and stomped out of the room.
"That went quite well, if I do say so myself, didn't it, Harry?" Dumbledore beamed.

"The Ritual's today", Harry said. He was actually bubbly, something that Daphne had never seen before. "The Ritual's today!"
It was a warm April morning, nearly four months since Peter Pettigrew was captured.
"Yes, everything is ready", Hermione said, staring that the perfectly made power potion. She measured out doses for each of them.
Harry began the process of drawing runic diagrams into the floor with Caliburn, and sprinkling over them with their blood.
"Indus Valley Blood Runes, second only to the lost Sumerian series."
"Why are the Sumerian Blood Runes lost anyway?" Daphne wondered, staring at the creations that Harry was carving into the stone.
"The legend is that they were so powerful that Gilgamesh didn't dare let anyone know about them, so he destroyed them. The truth is even more terrifying. They were used to forge some sort of weapon capable of driving the elves into hiding, and the fae away from this world. Even now, they haven't come back, out of respect for whatever it was. A side project of mine was crossreferencing the texts that speak of this, and I've come to the conclusion that the weapon in question was a sword."
"No. Anything but a sword. Anything! It's really a sword, right? Damn it!" Hermione palmed her face. "You aren't going to go chasing after it, are you?"
"No, the Sword of Rupture has been lost to time. The popular theories claim that one of the four races of higher sentience took it, though the ideas of goblins having it is sort of stupid, and dwarves are nearly extinct anyway."
"Faeries and High Elves. Picking your poison, Harry?" Daphne asked, shaking her head.
"No, I don't want to deal with either more than I already have", Harry said truthfully.
They sat down on the ground on the three sets of runes positioned in a triangular formation, and Harry retrieved the slip of paper that the Master Healer had given him.
He began to chant slowly, thinking of how he had received his wound. It didn't require much concentration, just a continual rhythmic chanting, and in a singular motion, during a pause in the chant, they all downed their potions.
He continued to chant as he felt the magic overflow from his core. He resisted the urge to jump to his feet and begin casting hundreds of extremely intensive spells. He felt as if he could continually cast Flitwick's Twenty Six Element Chain for days.
Then something completely unexpected happened.
Harry could feel the magic in each of them being stretched by the healing chant to accommodate the large amount of magic flooding into them.
Harry was capable of reading both of his companion's thoughts, and it seemed that Hermione had worked it out already. Our magical cores are doubling, tripling, or maybe more, because the chant perceives our cores as an injury, since we have more magic now.
He felt the wound in his arm slowly regenerate muscles and bone particles, then close up. He flexed it, and was very happy to notice that there wasn't any pain.
When Harry had begun the ritual, he had slightly more magic than McGonagall. Now, his magic approached that of Flitwick's - nearly three times as much as a generic wizard, and around half as much as Dumbledore.
Hermione and Daphne had both surpassed most of the teachers in the school in that respect as well, and half roughly half the amount of magic he had.
For a thirteen year old, that was impossibly impressive, but Harry was disappointed that his core hadn't improved more.
They sank into each other, exhausted, while their new magic acclimated itself to their bodies and replenished their stamina.
"Well, that went a bit better than expected, didn't it?" Harry remarked, still waving his right arm around.
"Now, what does this entire thing teach you, Harry?" Hermione began to lecture.
"That I have the best friends in the world."
Hermione blushed. "N-no, not that. I mean-"
"Arrogance is unbecoming?"
"Be more specific."
"Fine. If I'm going to be breaking four-dimensional wards, I should make sure that I haven't convinced myself that I'm invincible, because the wards are generally stronger than I am."
