Disclaimer- I don't own Harry Potter or Percy Jackson, except for my OC. J. K. Rowling and Rick Riordan do, not me. (Imagine they were in the same time period as Percy Jackson). This is based on the Harry Potter movies and the Percy Jackson books. This story is also found on Wattpad. I'll try to update two chapters the scheduled day if one chapter is short. If a chapter is long, then I'm keeping it to one chapter. Reviews are welcomed!

I hope everyone had a good Thanksgiving!

Bianca's POV

I didn't know how far I walked. I wanted to calm down before ice cubes start to fall from my eyes. Or perhaps a blizzard occurs...Or maybe a gigantic polar bear appears...

"Oompfh!"

I was knocked back to the floor.

"Oh, I'm sorry...Are you okay?" I heard an unfamiliar voice.

I opened my eyes, seeing a boy with brown hair and grey eyes looking down at me. I noticed the Hufflepuff tie and the badger on his robes.

"I-I..."

"My apologies...I'm so sorry for bumping into you! You're crying! L-let me help you up." He easily lifted me off the ground, checking for any injuries.

I stepped back."Um, it's fine. I'm alright. I'm sorry for bumping into you too," I apologized, wiping anything from my face, for I feared he would see something out of the norm.

He smiled."I'm Cedric." He extended out his hand."Cedric Diggory. Fourth year in Hufflepuff."

I smiled back, shaking his hand."Pleasure to meet you. I'm Bianca Mist. I'm in Gryffindor."

"I know. You play as Chaser for Gryffindor."

How did he...

"I'm Hufflepuff's Seeker."

Oh. Wonderful.

"That's nice to know."

I just realized that I was still shaking his hand, so I immediately pulled my hand away, feeling uncomfortable.

"Your hands are quite cold," he commented.

I let out a nervous chuckle."Yes..."

"Bianca!" I heard a familiar call.

We turned to the voice. Hermione was running towards us.

She finally reached me, panting."A-are you okay?"

I nodded."I'm alright."

She looked up, noticing Cedric still here."Oh...um...well, hello."

He flashed a smile."Hi."

She gave an awkward smile. She locked her arm with my arm, pulling me."Well, um...nice to meet you. I'm Hermione Granger. We'll be going now. Bye."

She dragged me off. I looked behind, seeing Cedric wave a goodbye.

"Bianca!" She squealed."Do you have any idea who you're talking to?"

"Um...you can stop dragging me now, Hermione," I chuckled.

She looked down at our arms."Oh...yeah. Sorry." She released me.

We walked up the moving stairs, heading to the common room.

"Um...Cedric Diggory?" I responded to her question."Hufflepuff's Seeker?"

"Not just Cedric Diggory, Bianca! Most girls fancy him!" She exclaimed.

I smirked."So including you?"

She blushed."Hey! That's not what I asked. Anyways, did you cause any...you know, disasters around him?"

We reached up to the singing Fat Lady Portrait.

"Pig Snout," we both told the password to the Fat Lady.

"Wait, hold on, I can break this glass." She took a breath."Ahhhhhhh~"

We clutched our ears.

"Pig Snout!" Hermione shouted over the shrieking.

The Fat Lady sighed."Alright, alright." She opened up to us."Come on in."

We entered.

"Of course not, Hermione!" I continued our conversation."Why would I have caused any disasters?"

She shrugged."Saffron warned me." She led me up to our dormitory."Are you feeling better? From the letter?" She laughed."Hah! That rhymes."

I smiled."Now that you're here, yes. What lame rhymes, Hermione. I can do better."

She scoffed."Bring it on. I bet I can rhyme with spells too!"

The next day arrived. The Polyjuice Potion was almost finished. All we needed was one more ingredient. Hair.

Hermione and I planned to retrieve the hairs from what we were gonna become as. I peeked my head out of the lavatory. I looked back at Hermione.

"Now," I hissed.

Hermione and I were exiting out of the girl's lavatory when two girls bumped our shoulders, causing us to separate.

"Oops..." Pansy Parkinson, a Slytherin, gasped.

The other girl, Millicent Bulstrode, giggled."My bad..."

I smiled, keeping myself cool, chill, and calm. I headed to them, dusting their shoulder off, hoping they won't notice what I just picked off.

"My apologies. As well."

They sneered at me. They spun around, flipping their hair at us. They continued striding their way.

At least we got what we've wanted...

Hermione got closer to me, guiding us back to the common room.

"You okay still?" She whispered.

I smiled."Of course." My hands opened up to the strands of hair."We've got what we needed."

Christmas has arrived. Knowing that Malfoy and his gang would be staying at Hogwarts for the holidays, we decided to go with the plan.

We rushed to the Great Hall, spotting Saffron, Harry, and Ron all eating. We sat down in front of them, grabbing a plate of food.

"Well, everything's set," Hermione whispered, looking around if anyone could hear. Then, she looked up at the boys."We just need a bit of who you're changing into."

"Blaise, Crabbe and Goyle," Harry responded.

"We also need to make sure that the real Blaise, Crabbe, and Goyle can't burst in on us while we're interrogating Malfoy," Hermione added.

"How?" Ron asked.

"I've got it all worked out," she said. She pulled out three cupcakes from her bag, presenting it to them."I filled these with a simple Sleeping Draught." She laid them down on the table in front of them."Simple, but powerful."

I grabbed one of them, examining it."It's so clever..." I awed at it.

Hermione smiled."Now, once they're asleep, hide them in the broomstick cupboard and pull out a few of their hairs, and put on their uniforms."

I watched the boys looked at one another.

"Wait, then whose hair are you guys ripping out then?" Ron asked Hermione and me.

"I've already got mine." She pulled out two flasks that contained two separate hairs."Millicent Bulstrode. A Slytherin. We've got these off her robes."

"Then, who's the other one?" Saffron questioned, pointing at the other flask.

"That's Pansy Parkinson's," I replied."The one who fancies Malfoy."

Hermione cleared her throat."We're going to go check on the Polyjuice Potion," Hermione told."Make sure that Blaise, Crabbe, and Goyle find these."

Hermione and I left to check on the Polyjuice Potion that was brewing in the girl's bathroom, while Saffron, Harry, and Ron get their hairs.

As we arrived in the restroom, we found our potion untouched. It's a good thing no one comes in here because of Moaning Myrtle. We sat down, checking the potion.

"This is insane...but I like it," I commented.

I pulled out five cups from Hermione's bag, setting them on the sink counter. Hermione pulled out the ladle to pour the potion into the cup. She began whisking the potion, waiting for Saffron, Harry, and Ron to come back. She began scooping a glob of the potion, giving each of us an amount.

"We're back with the hairs!" Ron exclaimed, entering the bathroom.

"It was successful?" I asked.

They all nodded.

I began taking out the two flasks, handing one that was hers and one that was mine."That's wonderful!"

Hermione finished pouring us the portions.

"We'll have exactly one hour before we change back into ourselves," she informed, handing each of us the Polyjuice Potion."Add the hairs."

We all sprinkled the hair we would soon transform into.

Ron groaned, staring into his cup."Essence of Crabbe..."

"Cheers!" Hermione said, bringing her cup in.

Our cups collided before we took a sip. We all drank our potion in one go. I closed my eyes in disgust, setting the cup down on the sink.

That was disgusting!

"Ugh...I think I'm gonna be sick!" Ron squeaked, dropping his cup. His cup shattered onto the floor, but he didn't care. He ran straight for a stall.

"Me too," Hermione agreed. She dropped her cup, resulting in another shatter.

I notice Saffron already running to a stall already. The smell of Pansy Parkinson reached up my nose.

Ugh! This taste!

I followed after them, entering an empty stall to try and contain my vomit. I gripped onto the toilet seat, trying to calm myself down. I squinted, feeling something bubble at the skin of my hands. I took my gloves off, watching my hands morph into longer fingers and longer fingernails.

"Pansy Parkinson," I whispered.

"Uh... Harry?" I heard Ron's voice.

"Ron!" I hear Harry exclaim."Saffron!"

I exited my stall, seeing Crabbe, Goyle, and Blaise. Not Harry, Ron, or Saffron.

"Bloody hell," we simultaneously gasped.

"We still sound like ourselves," Saffron said, looking at himself in the mirror.

"Ron, you need to sound more like Crabbe," Harry told.

"Uh..." Ron cleared his throat."Bloody hell..."

I giggled."Excellent," I complimented, impersonating Pansy's voice.

"Wait...where's Hermione?" Saffron brought up.

We looked at each other and then to the stalls area.

"I-I don't think I'm going," Hermione spluttered."Y-you go on without me!"

We inched closer to the stalls.

There's something wrong...

"Hermione?" Harry called."Are you okay?"

"Just go. You're wasting time!"

I turned to them."You guys go ahead. I'll check with her."

They nodded, leaving the girl's bathroom.

I turned towards the stalls.

"Hermione?" I called. I walked closer. I heard no response."Hermione?" I looked under the stalls, trying to locate where she was.

"She's over here~" Moaning Myrtle sang, flying in circles around the middle stall on the right side.

I knocked on the door."Hermione?" I called again. I pushed the door opened, seeing this humongous cat. I gasped."H-Hermione?"

She turned to me with the yellow eyes of her. Her cat ears wrinkled.

"It was cat's hair, Bianca..." She cried."It wasn't Millicent Bulstrode's..."

"I'm so sorry, Hermione!" I sighed, going closer to her. She coughed out a furball. I grabbed both of her shoulders, lifting her up."Come on, Hermione. Let's get you to the Hospital Wing." I turned to Moaning Myrtle, who was giggling at Hermione."If the others come back, please tell them that we're in the Hospital Wing."

I led Hermione out of the bathroom.

A month has passed, and Hermione was still in the Hospital Wing. She was going to be out of the hospital the next week. I was in charge of bringing her her homework, getting her food, and all that sort.

It was evening. I had finished eating dinner. I was on my way from the Gryffindor Common Room to deliver her bag that contained her homework she had to do. However, I stopped, seeing wet footsteps on the floor. It led to a dark corridor. I had the urge to investigate, but I turned back to the way that led to the Hospital Wing.

I have a bad feeling about this...but should I?

I stepped closer, heading to the dark corridor. I began to hear sobs and sniffles. I caught a dark figure sitting on the floor.

"Hello?" I called."Who's there?"

The crying and sniffling stopped. I reached for my hairclip. I slowly walked closer to the figure.

"B-Bianca?" A familiar voice whispered. I could recognize that voice anywhere!

"Ginny!" I called, running to the figure.

I haven't seen her in forever after the incident.

I set down Hermione's bag and sat down next to Ginny. I couldn't see her face very well due to the darkness. I managed to find her shoulders and grabbed it.

"W-what are you doing here, Ginny? Especially in the dark!" I whispered."It's almost curfew! You're gonna get into trouble!

She began wiping her eyes, sniffling."I-I..."

What I realized was that she didn't have that book with her. She always had it with her ever since the beginning of the year.

"What's wrong?" I demanded.

She gave me silence.

How am I supposed to help her when she won't answer me?!

"Ginny, please tell me so I can help you!" I screamed, shaking her."Please..."

I didn't want to lose someone who was like a little sister to me. The only little sister.

I decided to be straightforward.

That book was the problem...Stupid Malfoy...I had a feeling there was something strange about it...My scar would start itching whenever I was near it.

"Where's that book, Ginny?" I seethed."The book, Ginny. Where. Is. It?"

She looked up into my eyes."It's a diary, Bianca...I threw it..." She whispered.

"Where?"

"The bathroom," she replied.

I huffed."Could you go get it?"

Immediately, she shook her head and began crying again. I loosened my grip on her shoulders."Please, Bianca! Please don't let me go get it!" She bawled."P-please! I can't! The diary is too scary!" She clutched me very tightly."I-It's after you...and Harry, Bianca. The diary is after you and Harry."

My eyebrows furrowed.

A diary? What? Like a diary has feet and starts walking on its own?

"H-how, Ginny?" I questioned.

"I-" Ginny was cut off by a voice.

"Tsk...tsk..." We heard a familiar nasal voice. We looked up, seeing Professor Snape in his usual black attire."Why are you two here? Dinner has ended. There should be no roaming at this time."

"I-I..." I looked down, grabbing Hermione's bag."I was on my way to drop off Hermione's homework, but I noticed that Ginny was crying here. It seems like she got lost," I explained.

We made no expression."Lost, you say?" He eyes both of us.

I nodded. I turned to Ginny, who was wiping her eyes."Weren't you lost, Ginny?"

She nodded."Y-yes," she croaked.

I turned back to Professor Snape, getting up while helping Ginny to her feet."We'll be going now, Professor. Have a good night."

I pulled Ginny with me, passing Professor Snape.

"I'll take that to Miss Granger for you, Miss Bianca," he said.

I turned to him, smiling, but I was kind of curious why he would do this. I handed him Hermione's belongings."Thank you, Professor. Goodnight."

"You two as well." We turned around, walking to our away."The Headmaster would like to see you tomorrow morning."

I continued walking.

Unfortunately, Dumbly and I weren't discussing the Prophecy like I was hoping for. he wouldn't tell me any of it until I'm apparently of age. He just wanted to know how I was, but that was it.

Two weeks have passed. Hermione was already out of the Hospital Wing the other week already.

"The diary told me, guys, you've got to believe me," Harry pleaded as we walked across the courtyard.

Apparently, Harry found the diary that Ginny threw in the restroom and decided to read and write in it. Thank goodness he didn't become like Ginny though! He claims that Hagrid was the one that opened up the Chamber of Secrets. This is outrageous.

"Harry, listen to me, I have a bad feeling about this," I declared."I'm usually correct on these stuff!"

My mind recalled what happened with Ginny weeks ago. However, I didn't want to tell them about Ginny. I didn't want Ron to worry and start owling to his parents.

"Exactly! How could you possibly trust a diary!" Saffron agreed.

"It was Hagrid," Harry stated."Hagrid was the one that opened the Chamber of Secrets fifty years ago."

"It can't be Hagrid," Hermione agreed with me."It just can't be."

"We don't even know this Tom Riddle. He sounds like a dirty, rotten snitch to me," Ron said.

"Didn't you say that he won an award fifty years ago though, Ron?" Hermione asked, recalling when we were in the Hospital Wing with Hermione."That means he's trustworthy, right?"

Saffron and I looked at each other. We did not believe this at all.

"The monster had killed somebody, Ron. What would any of us have done?" Harry asked.

"Why don't we just ask Hagrid about it?" I suggested."He's our friend." I shook my head."Hagrid would never have done this."

Ron scoffed."That'll be a cheerful visit!" Ron changed his pitch."'Hello, Hagrid! Tell us, have you been setting anything mad and hairy loose in the castle lately?'"

"Mad and hairy?" We heard a familiar voice that sent us jumping."You wouldn't be talking about me now, would ya?"

We spun around, facing Hagrid.

Nah...he couldn't have. He's not the type to send a monster on a loose.

"No!" We replied in unison.

We eyed on what he was holding.

"W-what's that you've got, Hagrid?" Harry questioned.

"Oh, it's a Flesh-Eatin' Slug Repellent. For the Mandrakes, ya know. Now, accordin' to Professor Sprout, they've still got a bit o' growing up to do. But, once their acne's cleared up, we'll be able to chop 'em up and stew 'em, and then we'll get those people down at the hospital un-Petrified. In the meantime, though, you five had best be lookin' after yourselves. All right?" He turned around, walking away."Oh, hello, Neville!"

We watched a panting Neville running up to us.

"Harry...I don't know who did it, but you'd better come!"

What?

"Come on!" Neville yelled.

We all looked at each other and then followed Neville up to the castle.

We entered the boys' dormitory. The boys' dormitory was in ruins. It was a mess. Papers were shredded. Blankets and drapes were ripped off from its original place. Chairs were toppled over. Mirrors were cracked. Books were spread everywhere on the floor.

"It had to be a Gryffindor," Hermione said. Harry was reaching over to pick up his books that were laid everywhere on the floor."Nobody knows our password. Unless it wasn't a student..."

"Well, whoever it was, they must have been looking for something," Ron said, looking around at the mess.

"And they found it," Harry spoke up.

We all turned to him.

"What?" Saffron asked.

"Tom Riddle's diary is gone," he said.

I bet that diary has legs...

The next week arrived. I entered Dumbly's office. I wanted to talk to him about the past events but apparently, he got removed as Headmaster. He had to go somewhere to clear this situation up, so I decided to hang out with Fawkes.

"I bet next year will be crazier as well," I sighed, petting him.

I sat in his seat, pretending to be Dumbly. I opened his drawers. My eyebrows furrowed, seeing a picture of a blonde hair girl.

Who is she? And why is she in Dumbly's drawers?

I was going to pick up the picture to see it more clearly with my eyes. However, I began to hear a noise in his office, making me place the picture back into the drawers. I hear the sounds of birds chirping, water running, and chatting.

"Bianca!" I heard familiar voices call my name.

I spun around, seeing this image of Percy, Annabeth, and Grover.

My eyes brightened. I rose from Dumbly's seat.

"Annabeth! Percy! Grover!"

Is this Iris Message?

However, there was no sight of Thalia, Nico, or Bianca.

"How are you all?"

They looked to one another.

"Thalia joined the Hunters," Grover spoke up.

I frowned."The Hunters of Artemis?"

Joining the Hunters of Artemis means swearing loyalty to the virgin goddess, Artemis. You would join her in the Hunt and reject en for as long as they live while becoming immortal as well. Well, if you don't break your vows.

"So...I'll never see her again?" I whispered.

They exchanged glances.

"Well...if they do come to Camp Half-Blood again..." Percy mumbled.

"I didn't even say goodbye to her," I whispered sadly."So...where's Bianca and Nico? How did your quest go?"

"Um...well..." Annabeth began. She shook her head, letting her face fall into her hands."I really don't know how to explain this," she groaned. She turned away from me.

There was something wrong. Why does everything turn out wrong for me in my life?

"Please, tell me," I pleaded.

"Bianca died during the quest," Grover croaked, looking down at the ground.

No. You're lying...

"S-she...was trying to steal a Mythomagic action figure for Nico..."

Mythomagic action figure?

Grover continued."A-and she awakened a defective Talos..."

"T-then, where's Nico?" I whispered

Grover began to cry."I'm sorry, Bianca! I told you that I would save them for you, but I let you down!"

Annabeth laid her head on Percy's shoulders, possibly hiding her tears.

Percy looked away."I-I'm sorry, Bianca. I really am... I promised Nico that I would protect Bianca, b-but...I wasn't able to..."

I bit my lip. I didn't want to show any more of my weaknesses to anyone, so I decided to shut my emotions down. No tears were sighted in my eyes. No temperature dropped in my surroundings.

"So...he left camp, and we can't find him!" Percy cried.

I sighed, leaving the Iris Message and exiting Dumbly's office.

The month of May has arrived. I was sick of feeling emotionless all those weeks and months. Fred and George couldn't get me laughing. Well, maybe I lied. They made me laugh here and there and got me out of my state of silence, but I've been very reclusive and quiet throughout. Now, I decided to throw all of it away. I couldn't let those events ruin me while I'm here at Hogwarts. Once I get to Camp Half-Blood, I shall get to the bottom of this situation.

Today was the Quidditch match. There were some minutes before it starts. We were all in the tent, planning our strategies.

"Alright, listen up," our Quidditch captain, Oliver, exclaimed."We play our game, Hufflepuff doesn't stand a chance. We're stronger, quicker, and smarter."

We got up, heading out of the tent to go into the field."And not to mention, they're scared that Harry'll petrify them if they fly anywhere near him," Fred teased.

"Well, that too." We were about to enter into the field, but Professor McGonagall was in front of us."Oh, Professor McGonagall," Oliver greeted.

We looked up, seeing her. However, there was this concerned expression displayed on her face.

"This match has been cancelled," she informed.

What...

"We can't cancel Quidditch," Oliver objected.

"Silence, Wood. You and your teammates will go to Gryffindor Tower, now." Our team dispersed. She turned to Harry and me."Bianca, Potter, you and I will find Mr. Weasley and Mr. Clover. There's something you all have to see."

My forehead wrinkled.

Something that could be so important to cancel a Quidditch match?

Professor McGonagall was leading us into the Hospital Wing.

Why here?

"I warn you, this could be a wee bit of a shock," Professor McGonagall warned as we walked closer inside.

She led us to a familiar person, who was laying on the bed."Hermione!" We gasped.

No...not her too!

I reached for her hand, which was raised up and seemed so stone-like. I liked the feeling of her cold hands though, but it was abnormal for any other human beings.

First, Ginny. Then, Annabeth, who soon returned. Then, Thalia, Bianca, and Nico. Now, Hermione. What more?

"She was found near the Library," Professor McGonagall explained. Professor McGonagall picked up a mirror."Along with this. Does it mean anything to either of you?"

We shook our heads."No."

Saffron touched my shoulders, and I leaned towards him for comfort.

He was the only one that I told about the situation over at camp. I wanted to tell Dumbly, but he was dealing with how he was removed as headmaster of Hogwarts. I didn't want any more trouble for him. I recalled the first time I tried to charm speak him.

It wasn't my fault at all! Maybe I jinxed it...but I didn't want that to happen! It's all because of the Chamber of Secrets incidents!
