The two boys walked into the final chamber, and Harry looked forward in shocked. Y/N had been right the whole time. The Defence Against the Dark Arts teacher stood with his back to the boy's, staring into a large mirror.

"Professor Quirrell?" Harry gasped.

"Fucking told you" Y/N snarled as he moved in front of Harry in a protective manner.

Avada Kedavra

Y/N fired off the killing curse- a dark laugh echoing around the chamber as Quirrell stepped to his left.

The curse hit the mirror Quirrell was standing in front of, rebounding back towards the two boys. Y/N shoved Harry hard to the right, jumping to his own left as the curse whizzed past Y/N's ear and cannoned into the wall behind them, causing a small explosion.

Y/N pointed his wand at Quirrell from where he laid on the floor before stopping as Harry grabbed his head and started screaming in agony.

"Harry!" Y/N called, rushing over to his fallen friend. Quirrell turned and sneered at the boys:

"Wands down and over there L/N, or we turn up Harry's pain to eight. He's only sitting on a four right now"

Y/N scowled at Quirrell, throwing his wand across the room. The Professor smiled evilly:

"And the other one L/N!"

Y/N scowled and unsheathed his spare wand, throwing it to the same part of the room. Harry stopped screaming as he tried to slow his hyperventilating, Y/N rubbed his shoulder while glaring at the Professor.

Quirrell stood with his wand pointed at Y/N, smirking. His stuttering persona had completely vanished, replaced with a confident, evil guise. As Y/N continued to glare the Professor spoke:

"Of course you're here. You've suspected me all year haven't you. Every single lesson battering me with your little legilimency attacks. Just like your father, I knew you would be trouble. And you JUST WON'T DIE! No matter how many creatures I release against you".

Y/N scowled as he rose to his feet.

"You... it's your fault I had to kill the troll. I'm gonna rip your fucking heart out your chest".

Y/N took a step forward and Harry started screaming again. Y/N stopped in his tracks and looked back at his agonised friend.

"You understand now boy. How much your dear Harry suffers depends on how cooperative you are".

Y/N looked down as Harry stopped screaming again, muttering to himself

Fuck!

The Professor turned back to look at the mirror, staring into it. Y/N recognised it immediately. It was the Mirror of Erised.

"I see myself holding the Philosopher's Stone but how do I get it out?" Quirrell called out loudly.

"Use the boy" a second voice could be heard from... somewhere within the room, but Y/N couldn't figure out where from.

Quirrell turned, pointing and snapping:

"You, L/N, come here now".

Y/N glared at Quirrell as he walked forward. His mind was going overtime. He needed his wand to use the killing curse, he had to get it done quickly before Quirrell could react.

Y/N stood next to Quirrell, looking at himself in the mirror. He was suddenly pushed in the back aggressively, forcing him a couple of steps forward.

Y/N's head turned to the side as he snarled:

"You touch me again I'll stick your wand straight up your arse"

"Just look in the mirror!" Quirrell roared. Y/N shook his head then stepped forward.

He looked into the Mirror of Erised. At first he saw himself, older, about Dean's age. The difference was Y/N was huge. He had a full black beard, a weird mark on one forearm and a tattoo on the other one. Hermione suddenly appeared. She was older as well. It was definitely Hermione but she looked... different. Her hair was less bushy and was dyed blonde. Even though she looked really different she was just as beautiful as ever. She smiled at Y/N, then turned to Mirror Y/N and they kissed passionately.

They parted as Mirror Y/N winked and Hermione smiled. She held up two fingers and nodded, before holding up three fingers and they both winked at Y/N. Mirror Hermione then touched two fingers to her lips, kissed them, and moved them towards the mirror, placing them at the same height Y/N's lips were.

Finally, she held up her left hand. In it was a red rock that Y/N could only presume was the Philosopher's Stone. Hermione placed the rock in Mirror Y/N's pocket. Y/N was instantly aware of a weight in his own pocket. He shot a message to Harry:

I've got the stone. Hermione gave it to me in the mirror. We've gotta hold him off until Dumbledore gets here. Stay down and shut up. I'll keep him busy.

Y/N could hear the fear in Harry's voice in his head as he replied in a mental whisper:

Ok

Y/N looked in Hermione's eyes in the mirror, how happy mirror Y/N was with her and smiled. He saw first hand how people could fall under the Mirror's curse.

"What did you see boy!?" Quirrell screamed suddenly seeing Y/N's smile. Y/N chuckled as he looked up at Quirrell.

"I saw myself. Standing over you Quirrell. My foot.... in your arse" Y/N chuckled.

Harry's eyes widened from the corner he was huddled in.

"He's lying" the second voice yelled again. It seemed to be coming from Quirrell's... person... somehow.

Y/N was suddenly magically thrown across the room. He appeared to be bound by invisible ropes and he kicked and fought his way, trying to escape from the trap he was held in. Harry heard him grunting and groaning as he fought.

"You can't brute force your way out of these bonds boy! They're a curse. The harder you fight the more they constrict. Too big and stupid to work that out aren't you" Quirrell sneered at Y/N.

"Go fuck yourself you snivelling little bitch. I ain't telling you shit!" Y/N roared as he continued to fight.

Quirrell walked up and backhanded Y/N across the face, splitting his lip in the process.

"Fine. Fine. Fine. Fine. I didn't want it to come to this Y/N, but you've given me no choice!

Quirrell pointed his wand at Y/N

Crucio

Y/N groaned at the pain, his body feeling like it was being stabbed with a thousand knives every second. He pushed through the pain and grinned a bloody grin at his torturer. His eyes were full of sadistic intent.

"Is that the best you got you stuttering bitch?"

Quirrell roared at Y/N in fury:

"What madness is this? Crucio.... CRUCIO"

Y/N's body stiffened, his lip curled. He grunted in pain before pushing through it again, death staring the man who was torturing him. Quirrell released the curse and stared in disbelief as Y/N glared at him and spat blood out of his mouth, snapping:

"Is that the best you've got maggot? My fucking brother has tortured me worse than that"

Harry, still sitting and hiding back in the corner, felt his jaw drop in response to Y/N's taunt. Jacob had tortured Y/N? He was more stunned at what Y/N did next. He laughed at Quirrell. He actually laughed at him, saying dismissively:

"You ain't shit Quirrell."

The second voice was heard again as Harry's scar burned intensely once more.

"Let me talk to the boy."

"Yes master" Quirrell said as if in a trance. He turned and unwrapped his headdress.

Harry's eyes went wide in horror. Y/N, still recovering from the after affects of multiple Cruciatis Curses, looked at the hideous mess in front of him momentarily before he laughed loudly.

"Hahahahaha. You're seriously walking around with Voldemort on the back of your head? The great and mighty Voldemort turned into nothing more than a parasite. You're a sexually transmitted disease Volde. I wonder if you can take some muggle medicine for that Prof-"

Crucio... Crucio

Voldemort's face tortured him this time, taking control of Quirrell's body. Y/N's lip curled as he grunted and gritted his teeth. The curse was released and Y/N's head dropped. He was still magically bound to the wall and it seemed to be supporting his body weight.

"Yeah that one stung a bit. Well done you two, you're improving" Y/N chuckled, spitting out more blood. He looked up directly into Voldemort's eyes and grinned.

"Come on two face. Is that the best you've got?"

Voldemort laughed loudly, the sound filled Harry with dread.

"You know Y/N L/N, you are an interesting one. I can usually tell the character of a man by sound of his heartbeat".

Quirrell started to rhythmically clapping.

"Usually when I approach..."

Quirrell clapped faster.

"I can dance to the beat. Poor Harry over there"

Quirrell clapped even faster. Harry gulped, wondering how Voldemort knew he was terrified and his heart was about to beat out of his chest.

"But you..." Voldemort continued with a tone of puzzlement as Quirrell's claps slowed to a seemingly slothish pace.

"...strange that yours is so steady."

It was Y/N's turn to chuckle as he looked in Voldemort's eyes, still trying to force his way out of the magical bonds that restrained him.

"You ain't never met someone like me before Volde."

"No. You are the Prophesied One after all aren't you?" Voldemort smirked.

Harry looked at the look of distain on Y/N's face.

"Yeah, so people keep telling me"

Voldemort started cackling.

"Wait... you don't know what that means do you?"

Y/N just glared back.

"Oh this is too much... Hehe... All the training. All the pain. All the torture. And they didn't even tell you why? You didn't think to ask? You are just a dumb animal aren't you Y/N. Blindly following orders. Nothing but a blunt instrument of war."

Y/N remained quiet, glaring at Voldemort even harder.

"You are the Prophesied One, Y/N. You're the one who is supposed to kill me. Do you think you're up to the task?"

Harry's eyes widened in shock. Y/N was going to kill Voldemort? Y/N stared, his eye and lip twitching as he replied:

"Release these bonds and let's find out".

Voldemort laughed again as Harry looked at Y/N. He had seen his friend angry before, furious. This looked nothing like that. It looked like Y/N had gone passed angry to a white hot calm rage. Harry was terrified. Voldemort continued:

"I bet you don't even know who your family is? Who your grandfather is? Well if you won't talk... maybe torturing little Harry Potter will loosen your tongue".

Y/N exploded.

"No. You don't FUCKING touch him. Look at me. Look at me you son of a bitch. Look at me!"

Y/N thrashed about like crazy. His arm managed to push a foot from the wall before being snapped back.

"You keep away from him you FUCKING CUNT!!!"

Y/N continued to roar and thrash as Quirrell approached Harry and turned around. Voldemort sneered at the boy who lived as Harry's scar began to burn again.

"The pain you are about to feel is because of your protector, Harry. He failed you. Never forget that."

Quirrell held up his wand as Harry flinched and waited for it- but the blinding pain didn't come. He looked up puzzled as Quirrell turned Voldemort to face Y/N. Harry looked over at Y/N and his mouth dropped open.

Y/N was thrashing like crazy, roaring as wisps of Blue Flames were shooting from his body.

"You don't touch him. You don't ever fucking touch him. I'll kill you you hear me! I'll fucking kill you....

Y/N's voice distorted, his eyes completely blackening as a blue fireball erupted from him, crossing the room in an instant. It struck Quirrell and he screamed in agonised pain. He was burnt to ashes right in front of a terrified Harry.

The flames reached Harry and he felt...
nothing.

No pain. No heat. Nothing.

A black mass rose from the pile of ashes that was Quirinus Quirrell and flew out of the chamber at high speed.

The flames disappeared as quickly as they had appeared. Harry, still terrified, looked over at Y/N who was released from the Magical bonds and fell to the ground unconscious.

Harry rushed over to his friend in panic. He could see Y/N was still breathing but was out cold. Harry didn't know what to do as he sat next to his unconscious friend.

-~-

After what seemed like an eternity, but in actuality was about twenty minutes, Dumbledore walked into the chamber with a worried smile.

"Are you ok Harry?" The Headmaster asked with concern. Harry nodded.

"And Y/N?"

"He's unconscious. It was Professor Quirrell- he-"

"All in good time Harry. All in good time. Let us get you both to the hospital wing first"

-~-

Harry arrived at the hospital ward, walking next to Dumbledore and an unconscious Y/N that the Headmaster was levitating.

Hermione and Lavender were sat next to Ron, Hermione shrieking at the sight of Y/N as she rushed over to the bed he had been levitated to.

Harry smiled at Ron who was awake and looking much better. The Headmaster turned to Harry with a smile:

"Perhaps you could tell us now, what happened in that Chamber, Mr Potter?"

Harry nodded.

"Y/N and I went through the potion test after we send Hermione back and Professor Quirrell was waiting there".

"Not Snape?" Ron asked, completely
shocked.

"Y/N told you all year" Hermione snapped angrily as she held Y/N's hand. Ron looked down.

"He wasn't alone. He had Voldemort on the back of his head. I fell to the ground in pain with my scar and Y/N went to the mirror, distracting Quirrell away from me. He said..."

Harry rushed to the bed and reached into Y/N's pocket. He pulled out the red stone in awe and handed it to the Headmaster. The Philosopher's Stone.

"Y/N said, in my head, that Hermione had given it to him, in the mirror".

Hermione looked puzzled as she replied: "But I wasn't there."

The Headmaster smiled:

"Perhaps I can explain Ms.Granger. The only person who could find the Philosopher's Stone in the mirror was someone who wanted to find it, but not use it. As for your appearance, as I told Mr.Potter at Christmas..."

He chuckled.

"The mirror shows us nothing more than our heart's deepest desire"

"So that means..."

Hermione couldn't finish her sentence and burst into tears as she gripped Y/N's hand tighter. Despite everything, she was what his heart desired most. Lavender ran over and hugged Hermione from behind. Harry continued:

"The Leviathan Professor, and the troll on Halloween. Quirrell released them both. He wanted to kill Y/N. After Y/N found the stone he said to me, in my head, to keep quiet in the corner, to hide, and that he would keep Quirrell busy until you got there"

Harry looked down as tears fell down his cheeks.

"Y/N mocked Quirrell, told him he saw Quirrell in the mirror with Y/N's foot in his ar- um, bum".

Ron laughed loudly. More tears fell from Harry.

"Y/N was thrown against a wall and held there, magically. Quirrell said it was a curse, that the harder Y/N fought back the more it would hurt him. Y/N didn't stop fighting Headmaster. Not once".

Harry inhaled deeply as he wiped his eyes and steadied himself.

"Professor Quirrell tortured him with the torture curse..."

Hermione gasped as she cried harder, holding a still unconscious Y/N's hand to her face. Lavender rubbed her shoulder as tears of her own fell.

"...over and over again. Y/N kept insulting him. It was like he was egging him on. He grinned at Quirrell the whole time. He didn't scream or cry. Just grinned. Told Quirrell Jacob had tortured him worse than Quirrell had"

Lavender gasped. Hermione didn't react.

"Then Quirrell took his turban off and he had Voldemort attached to the back of his head. Voldemort used the torture curse on Y/N. It... hurt him... but he kept mocking Voldemort".

Madam Pomfrey, who was examining Y/N, discreetly wiped a tear from her eye. Harry saw it as he continued:

"Voldemort started saying how he was puzzled by Y/N. He said how he could tell the character of a man from the sound of his heartbeat".

Harry started to recreate the clapping of Quirrell.

"He said most people were scared when he met them, he said I was terrified. He found it strange that Y/N was so calm. Y/N wasn't scared at all Headmaster. But then Voldemort said something to him. He said that Y/N is the Prophesied One. Said that Y/N was the one who would kill Voldemort."

The rest of the group were in complete shock at Harry's statement. Dumbledore's expression didn't change.

"So that's what those weirdos from the Department of Mysteries were talking about. That's why he is so important!" Lavender said loudly.

"Voldemort then started making fun of Y/N, because he didn't know. Said he was nothing but a dumb brute. I think that really got to Y/N. After that is when he walked to me. Said if Y/N won't break that seeing me in pain would break him".

Dumbledore's eyebrow raised.

"Y/N went crazy. Started yelling and swearing that he couldn't touch me. Then Voldemort said to me that it was Y/N's fault I was about to suffer. That my protector had failed. Do you know what he was taking about Professor?"

"Perhaps, but please continue Harry" Dumbledore said dryly. Harry nodded.

"Just as he was about to torture me blue fire started coming out of Y/N".

Dumbledore has remained calm and stoic the entire time during Harry's retelling. At the mention of blue flames though, a distinct expression of concern crossed his face.

"Blue-Blue fire?" Dumbledore asked with a worried tone. Harry nodded, noticing the fearful look on the Headmaster's face.

"Yeah, it was small at first but got bigger. It flew across the room towards us. It turned Quirrell to ashes. His screams..."

Harry shuddered.

"...but when it touched me I didn't feel anything. No pain, no heat, nothing".

"Do you know what it is, headmaster?" Hermione asked.

"Perhaps. But each potential answer is more concerning than the previous" Dumbledore answered. Harry spoke up again. Albus Dumbledore panicked at the Boy Who Lived's words:

"Oh one last thing. He also said to Y/N 'I bet you don't know who your grandfather is'"

The group sat quietly. Dumbledore eventually turned to Madam Pomfrey as she finally finished checking Y/N:

"What's your diagnosis Poppy?"

"Magical exhaustion. He will be out for a day or so I would say. Whatever he did taking out you-know-who has wiped him out, but there's nothing serious here"

"Best news I've had all day Poppy" Dumbledore smiled. "Now we should let Y/N get some rest. The Quidditch Final is in two days time after all"

Hermione saw right through the fake/brave smile Albus wore.

Ron was discharged and the Gryffindors were all sent away to the common room. Hermione stopped at the door and looked back, conflicted, before sighing and leaving with Lavender.
