As the five Gryffindors walked down towards the Great Hall, Y/N and Hermione in the lead, they were chatting happily before Hermione suddenly stopped dead in her tracks, even though she was still attached to her boyfriend's muscular arm.

Their way forward was blocked, by Peeves. In the narrow hallway they were trying to pass through tables and chairs were stacked floor to ceiling while the pesky poltergeist looped in the air, cackling.

"Oh, did the itty bitty Gryffinpoos want to progress? Can't until you say the magic word Peeves likes the best" the Poltergeist chuckled as more chairs and desks appeared in front of them.

"Peeves, I'm not in the mood to miss yet another Halloween feast. Move this mess... now!" Y/N growled.

"Does Y/N think he Peeves should fear? He maybe a L/N but he's just a third year" the ghost cackled again. Y/N's lips snarled, he went to take a step forward before he was held back by the hand.

"Please Peeves, let us through?" Hermione asked sweetly. Peeves blew a raspberry at her and laughed.

"Bloody hell" Ron whispered to Harry, who nodded at the same time Y/N snapped:

"Fuck this!"

As he walked up to the arrogant spectre.

"Hey Peeves, come here I've got a secret for you" Y/N stated, his left arm aiming towards the floor, his hand bent forward ever so slightly.

The poltergeist chuckled sadistically as he glided towards Y/N.

Thcck

The arrogance was quickly replaced by shock, pain, and then fear in quick succession.

"Ahhhhh" Peeves screamed in actual pain, the other four Gryffindors jumped in fright at the large squeal as Peeves looked genuinely terrified, his leg cut wide open with a hole in it.

Harry, Ron and Lavender looked forward in shock as Y/N held his concealed weapon to the ghost's throat:

"That cut was a warning, Peeves. See this?"

He held his blade up at eye level with the terrified spectre.

"This is an Angel Blade. It kills anything in creation. Anything! I've already killed a vengeful wraith with it. You'll never see it coming."

The disbelief of the third years grew as Peeves actually started crying. Y/N asked coldly:

"Whom do you serve, Peeves?"

"Y..y...you Mr. L/N, sir" the scared spectre replied through sobs.

"Good Peeves" Y/N replied as he sheathed his blade.

"Now clear this mess up and then go annoy Draco and his idiot friends for me. Really mess with them."

Peeves face turned from fright to joy as he nodded enthusiastically:

"Yes boss your word is law, Malfoy's peace will be no more!"

With that he and the furniture disappeared in a flash. Y/N smiled turning to see a worried look on Hermione, Harry and Lavender's faces, while Ron was pale as a corpse.

"Wh-wh-What is that, Y/N?" Ron whimpered in genuine sheer terror.

"My secret weapon, Ron. Not a word to anyone. Ever. I'm trusting you with this."

His blade unsheathed again.

"Understand?"

The blade resheathed.

"Yes. Not a word... no problem" Ron spoke in a squeaky terrified voice.

Lavender walked up next to Y/N and examined his wrist and forearm, she had been curious about the blade since she met the angel in DADA, but she hadn't wanted to ask.

"There isn't even a scar. Does it hurt when it comes out?" Lavender asked with a mix of intrigue and concern.

Y/N chuckled back: "Everytime. But now we don't have to worry about Peeves anymore. Come on."

He cheerfully took hold of Hermione's hand again and continued walking, the other three following the couple.

"So what did you do today? Did you get any work done?" Hermione asked Harry, trying to change the subject quickly away from the weapon in Y/N's arm.

"No I went and saw Professor Lupin. He made me a cup of tea in his office. And then Snape came in with a goblet of some steaming potion for him-"

"And he drank it? Is he mad?" Ron screamed.

Hermione and Lavender both shot Ron a look instantaneously knowing where this would go as Y/N asked coldly:

"So Ron, I'm not sure if I should slag off your Mum's cooking or your Dad's wardrobe? Which would you prefer?"

"What?" Ron asked snappily with a confused tone. "Why would you badmouth my parents?"

"Well you're constantly badmouth Sev, seems only fair"

"Why are you calling him Sev? And it's not fair he's not your dad!"

"HE'S AS GOOD AS RON!" Y/N roared back, causing all students in the corridor they had just entered to stop and look.

Y/N stopped and turned to Weasley with fire in his eyes.

"And I'm at my last fucking nerve with you talking shit about him. Back off. This is your only warning!"

The atmosphere dropped around them, a cold breeze suddenly picking up in the hallway as the friends noticed happened whenever Y/N got upset.

Ron gulped and took a step back. Harry stood there motionless unsure what to do, Lavender looked at Y/N, his hand twitching, ready to unsheathe his wand in a moment, practically begging Ron to say something else.

Hermione stepped between the two and placed a hand gently on Y/N's cheek, drawing his eyes to meet hers.

"Come on love. I'm sure Ron has learned his lesson. How bout we sit with Cedric and Beatrice for the feast, it would be lovely to catch up with them?"

Lavender watched and smirked as the anger could almost be seen leaving Y/N's body at Hermione's gentle touch and heavenly sweet voice.

"Yeah, yeah ok. Sorry love".

"It's fine baby, we all know how protective you are about people you care about. Let's go" Hermione replied with a sweet smile.

She took his hand and walked him gently towards the Great Hall, Ron breathed a sigh of relief as Lavender and Harry shook their heads and followed behind the couple.

"Never realised you had the gift as well 'Mione" Lavender chuckled.

"What do you mean Lav?"

"Well big boy there may talk to Creatures, but you're the only one who can calm that particular savage beast" Lavender said smirking with a devilish glare.

Harry and Hermione laughed as Y/N turned around looking offended.

"Hey"

Lavender chuckled as she squeezed his cheek.

"He's so adorable when he doesn't know how to take a joke" and walked off with Harry still laughing.

"Come on you savage beast, lets go find our friends" Hermione giggled, taking Y/N's hand again.

—~—

They had a very enjoyable Halloween feast, the first one they had been able to partake in at Hogwarts.

They sat at the Hufflepuff table, which wasn't generally allowed at feasts- but by this point Y/N had basically free reign to do as he pleased. He had saved the school the previous year, and the Philosopher's Stone the year prior. It was good to have runs on the board.

After chatting with Bea and Cedric the couple returned to their common room, or at least tried to. There was a large build up of students in front of the Gryffindor common room portrait door.

"What's going on?" Y/N asked Ron, Harry and Lavender who had stopped in front of them.

"Probably Neville forgot the password again" Ron said in an aggravated tone.

"Hey" Neville said out loud behind Y/N.

"Oh, Sorry Neville" Ron said awkwardly. Suddenly Percy pushed passed everyone, snapping as he did:

"Out the way all of you. Move. I'm head boy."

"Head dickhead more like" Y/N said quietly, causing Ron and Harry to laugh and Hermione to slap him on the arm.

"I saw you smirking baby" Y/N laughed at his disciplinarian.

"Shush. I was not" Hermione replied, trying her hardest to give her boyfriend a serious face but she was failing miserably.

Damn his cute smile she thought to herself. She was relieved when Ginny came running up. It didn't last long.

Ginny grabbed Y/N's arm. She looked terrified out of her mind. Y/N looked down at her with concern. "Gin, what's wrong love?"

She looked up at her godbrother before hugging into him.

"It's the fat lady, she's gone!"

Y/N wrapped an arm round his younger 'sister' as she hugged into his chest, shh'ing in her ear to calm her while he glanced at Hermione. She returned his worried stare.

"Bout time, her singing was bloody awful" Ron chuckled. Lavender smacked him across the back of the head.

"It isn't funny Ronald" Lavender said smacking the back of his head again. Suddenly they heard Percy yelling.

"Make way for the headmaster".

Dumbledore and McGonagall walked through the crowd, and arrived at the Fat Lady's portrait, it was torn to shreds.

Suddenly they heard Peeves cackling.

"She's gone a runnin won't find her unless you're cunning"

Y/N pushed through the crowd and stood next to the headmaster and Professor. He spoke loudly in a deep bellowing voice before Dumbledore could reply to the pesky poltergeist.

"PEEVES. WHERE IS SHE?"

Everyone, especially the professors, were shocked when Peeves whimpered in fear before floating down to Y/N.

"Yes boss Mr. L/N sir, she's over there sir she's hiding there"

He pointed to a portrait and suddenly disappeared. Everyone scampered to get closer to her, ignoring Percy's demands that he was the head boy before a bellowing voice was heard again.

"STOP. NOW!"

The Gryffindor students all stopped dead in their tracks and looked at the intimidating third year.

"Kindly allow the Headmaster and Professor through!"

He spoke firmly. This wasn't a request. The students all stood to the side as Dumbledore gave Y/N a worried glance before nodding.

They approached the portrait hiding the buxom painted woman and the headmaster spoke kindly to her.

"My dear lady who did this to you?"

"It's him, the one they all fear. Eyes like the devil he's got. Him. Sirius Black".

She shrieked in fear before hiding.

"All students will return to the great hall immediately" the headmaster bellowed.

Y/N returned to Hermione's side and took her hand with his right hand and placed his left on Harry's shoulder.

"Harry, stay close to me, right in front of me ok. I've got your back. If he turns up you grab Hermione and go, straight to the nearest teacher. I'll take Black."

Harry looked at Y/N stunned, as Hermione started arguing:

"Baby no...."

Y/N spoke again, respectfully to his girlfriend but firmly.

"Hermione love, this isn't up for debate. I'm the only one of us who can take him if he makes a move on Harry."

Hermione nodded as Harry started arguing.

"No Y/N, I'll fight him with you!"

Y/N squeezed Harry's shoulder gently, not to hurt him but to show affection. He placed their foreheads together as he spoke.

"Harry, brother, I'm not doubting your courage. But I can't fight Sirius if I'm concerned for the two of you".

Harry sighed and nodded, understanding what Y/N meant. He finally started to understand what the cryptic talk of Y/N being his protector meant. Right now, in situations like this, he had to follow Y/N's instructions. This is what Y/N's training has been for.

Harry felt a strong pull of both gratitude for his brother, but sadness at the amount of pain and suffering he had been subjected to just for Harry's sake.

—~—

They arrived at the great hall with no sign of Black but the long tables were missing. There were piles of pillows and sleeping bags as they entered. The five friends set themselves up in relative privacy as the teachers spoke among themselves not far away.

"Minerva you and Pomona take the second and third floor. Filius, you and I will take four up. Lupin, you and Hagrid search the grounds. Severus you check the dungeons and the first floor. Percy and Penelope we will leave you in charge of the other prefects while we are gone."

They all nodded at the headmaster before they heard a voice calling out.

"No. No way."

The group of friends looked almost as shocked as the teachers as Y/N got up quickly and yelled out as he approached the headmaster.

"No way in hell you're going by yourself!" Y/N roared, looking at the Potions Master as he spoke.

"What do you suggest Mr. L/N" the headmaster asked, seemingly shocked at the assertiveness of the third year.

"I'm going with you Sev- uh sir. I'll watch your back."

"No. Absolutely not Y/N." Dumbledore answered firmly.

"He's not going alone with Black potentially in the school, headmaster" Y/N replied just as firmly.

"You are not leaving this room, Y/N!" the Headmaster answered angrily. The whole room seemed to have stopped their conversations and were looking at the pair.

Y/N's lip snarled, his wand descending as he stepped forward, death glaring his Headmaster and asking coldly:

"And whose gonna stop me?"

Before it could go any further Severus stepped in the middle of the two and placed a hand on his godson's shoulder.

"Thank you Y/N, I appreciate the assistance" Snape said warmly.

The headmaster sighed: "Fine. But do not try and engage Black if you see him."

Y/N smirked and replied: "Fine, but how about we try and have a more coordinated search, sir?"

Before Dumbledore could answer Y/N called out "Hati" before briefly closing his eyes.

The Great Hall was filled with shrieks as a giant white wolf appeared in front of the teachers and Y/N. Some of the teachers even stood back in fear.

Y/N smiled and connected his forehead to the great wolf's one.

Two seconds later there was a squawking as Na-Hath flew in the hall and landed on Y/N's shoulder.

"Hati, my great and faithful companion, Na-Hath my majestic Phoenix. I need you both to search the grounds for me. Hati you search the Forbidden Forest, Na-Hath you fly above the castle and grounds. We're looking for Sirius Black, he will likely be in shabby looking clothes, and won't appear like a normal person. Report to me immediately if you see him, don't try and engage him yourselves."

The wolf howled and many students who hadn't seen the beast whisperer in action were stunned as Y/N argued back and forth with the great beast.

"No Hati, this is an order from your Alpha. You are not to engage. I don't want you getting hurt." Y/N spoke firmly, with authority, but also affection. The wolf howled in defeat.

"Thank you" Y/N replied, connecting their heads again and then after moving back as he stroked the Phoenix's chin.

"Both of you stay safe and report to me if you see anything."

With a howl the wolf disappeared and with a squawk the Phoenix flew into the air and out the hall.

Y/N turned to the stunned teachers who observed what happened.

"Ready to go sir?"

The potion master nodded as Hermione ran up to Y/N and hugged him.

"I won't stop you, but please be safe."

Y/N lifted her chin with his large hand before kissing her passionately and then whispering:

"I will my love. I will. I can't let him go alone."

"I understand, just come back to me" She pleaded as tears threatened to escape her eyes.

"Always" Y/N smiled, kissing her again before leaving with Severus.

Lavender rubbed Hermione's back as they watched Y/N leave.

"It's ok 'Mione. He's got this".

"I know Lavender. Doesn't make it any easier."

Lavender hugged her and walked her back to their spot. She talked with Ron and Harry while Hermione stared at the great hall doors with concern.
