Bianca's POV

After seeing Hermione, Harry, Ron, Saffron, and I headed back to the Gryffindor Common Room. Saffron stuck close to me in case I break down and cause a blizzard to storm in, but I knew how to shut myself down. So, we all don't need to worry much. As we entered the common room, there were a lot of Gryffindors around, whispering among another.

Fred and George ran up to me. They were still in their Quidditch uniforms, just like Harry and I.

"Hey, we heard about what happened. You okay?" George asked.

"I'm fine."

The twins turned to each other, shaking their heads,

"You're lying, aren't you?" Fred began.

"Yeah, you're not a very good liar, Bianca, just saying," George added.

"I'm fine...I-I just..." I stopped. I didn't know what to say.

Yep, life is great, especially when my best friend has been frozen by a giant snake. Yep, I'm okay.

"Bianca?" Fred called."Bianca? You alright?"

Saffron shook me."Bianca."

"Oh, sorry..."

We watched Professor McGonagall walk in through the entrance of the Gryffindor common room, carrying a scroll with her.

"Could I have your attention please?" Professor McGonagall spoke up. We were all silent."Because of recent events, these new rules will be put into effect immediately." She unraveled out her scroll."'All students will return to their house common rooms by six o'clock every evening. All students will be escorted to each lesson by a teacher. No exceptions,'" she read."I should tell you this: unless the culprit behind these attacks is caught, it is likely the school will be closed," Professor McGonagall finished. She exited, leaving us astonished.

Just why...

My eyes spotted Ginny, looking frantically around.

Why does she look so suspicious...

Harry pulled Ron, Saffron, and me closer to him.

"We've got to talk to Hagrid, guys," Harry whispered to us.

"What if it isn't him, Harry?" I asked.

"Then what if it is him, Bianca? If he did set the monster loose last time, he'll know how to get inside the Chamber of Secrets, and that's a start."

I sighed.

"You heard McGonagall! We're not allowed to leave the tower except for class," Ron argued.

"It's time to get my Dad's old cloak out again," Harry whispered.

"And how are we all supposed to fit in that cloak?" Saffron wondered.

We all tried to come up with solutions.

"I can stay back," I spoke up."Besides, it's very dangerous for me to be wandering out there." I turned to Saffron."You should go ahead with them."

"Bianca, I'm not letting you stay here with that monster on the loose in this castle," Saffron objected.

My face softened."I'm not letting these two go alone." I gestured to Harry and Ron."Please, go with them. You're a protector. As you protect my life, protect theirs." He finally nodded, agreeing."I'll follow Professor McGonagall's rules. Nothing will get to me. I promise."

Night arrived, and Saffron, Ron, and Harry had already left towards Hagrid's Hut. I couldn't stay in the Hospital Wing to be with Hermione, so I stayed awake in the girl's dormitory. I began to move down to the common room because I couldn't sleep, knowing that those three were out there. I decided to sleep on the couch, waiting for them.

"Bianca! Bianca!" I keep hearing voices.

"Is she dead?" I heard a familiar voice crack."She's not Petrified, is she?"

"No, Ron, she's sleeping, can't you see?" I heard Harry's voice.

My eyes fluttered open, seeing Saffron, Ron, and Harry above me. Their hair was a mess, and their clothes were a bit shredded.

"Oh..." I sat up, looking around at the darkness that surrounded us except for the fireplace that radiated light."You guys are back? How was it?"

Ron groaned."Awful Bianca!"

"Well, that's because you're the one afraid of spiders," Saffron commented.

"Spiders?" I asked.

"We found out that Hagrid never opened the Chambers of Secrets at all," Harry explained.

Uh huh! I told you so!

"Yeah, and we ran into these humongous, hungry spiders." Ron shivered."Worst experience of my life." He sighed in relief, patting Saffron's shoulders."Good thing Saffron was there with us with his sword thing."

"Rapier, to be exact," he corrected

"Yeah, that. Still a sword, ya know."

A few days have passed. Everyone has been following the rules and curfews that were established to lessen the attacks. We've all been visiting Hermione in the Hospital Wing, as well as trying to figure out a way to find the monster that's loose in the castle.

It was free period, and I was in the Gryffindor Common Room, up in the girls' dormitory, taking a nap on my bed. I felt kind of empty without Hermione below me and her waking me up so early in the morning to get to class.

Suddenly, I began to feel this tug on my uniform skirt. I stirred in my sleep, groaning, turning away from whoever was grabbing at me to get more sleep. I felt a someone shake me again.

"Ugh...I'm sleeping right now..." I mumbled.

"You have to come with me," I heard this monotone voice.

My eyes shot open, recognizing this voice.

Ginny.

I shifted the other way, seeing a pale Ginny, who was still in her uniform, waiting patiently below me.

What...

I sat up."W-what's wrong Ginny? Is it dinner time?"

"You have to come with me," she repeated.

I raised my eyebrows."Why?"

"Tom wants to see you."

Tom?

"Ginny, who's Tom?"

"You'll see. Follow me." She turned around and walked away.

What...Just happened...

I climbed down from my bed, landing on the floor. I put on my shoes and ran after her, running down the stairs. She was taking her time walking to the exit of the common room.

"Ginny!" I called."Wait up!"

She exited out of the common room, walking to the moving stairs.

"Ginny!" I caught up to her, grabbing her arm."We're not supposed to be out."

"You have to see him," she insisted."Tom wants to see you." She pulled her arm back, continuing to walk.

Tom...As in Tom Riddle? The one Harry was talking about?

"Hold on!" I grabbed Ginny's arm again, spinning her around to face me.

Pale.

I eyed the familiar book that was tucked in her skirt, but it was visible to see.

The diary...

"Ginny...Hand me that diary," I whispered, inching closer to her.

She shook her head."No! It's Tom's!"

I clenched my teeth."Ginny. Give. It. To. Me. Now."

She ran for it, and I began to chase her. Our feets banged against the castle's floor. My heart raced after her. She made a sharp turn, entering the familiar bathroom. I slipped on the wet floor, but I was able to keep my balance. I was finally able to catch up to her, gripping onto the back of her uniform shirt, making her halt.

"I smell blood...Fresh...Let me kill you..." I heard a hiss."You half-blood..."

I froze, staring at the pale Ginny, whose back was facing me. She was looking at the opposite direction. I reached the hairclip on my head, unclipping it. I tightly gripped my dagger in my hand. I took a glance at my dagger for a reflection and noticed a large, slimy figure, slithering my way. Its yellow eyes were the only thing I saw.

Saffron's POV

Harry, Ron, and I were coming back from the Hospital Wing after visiting the Petrified Hermione. Bianca was taking a nap in the girls' dormitory. It was the safest place beside the hallways or corridors. During our visit, Harry had found a note that Hermione was holding. We ran out of the Hospital Wing with the note.

Harry began to read the note."'Of the many fearsome beasts that roam our land, none is more deadly than the basilisk. Capable of living for hundreds of years, instant death awaits any who meet this giant serpent's eye. Spiders flee before it.'"

"So...this monster is a basilisk," I confirmed.

"Yeah! Saffron was right! It is a snake!" Harry exclaimed."That's why I can hear it speak!"He turned to Ron and I."Guys, this is it. The monster in the Chamber of Secrets is a basilisk.

"But if it kills by looking people in the eye, why is it no one's dead?" Ron questioned.

"Because no one did look at it in the eye..." I calmly responded."The boy with the camera saw the basilisk through the camera."

"And Justin...he must've seen it through Nearly Headless Nick!" Harry added."Nick got the full blast of it...but he's a ghost, so he couldn't die again..."

We turned to a corner.

"Hermione...she had the mirror. She must've used it to look around the corners, in case it came along," I included.

"And Mrs. Norris? I'm pretty sure she didn't have a camera or a mirror, guys," Ron pointed out.

We were all silent.

"The water," Harry interrupted the silence."There was water on the floor that night. She only saw the basilisk's reflection. 'Spiders flee before it,'" Harry read the sentence again. His eyes widened more."This all fits!"

"But how's a basilisk been getting around?" Ron asked."A dirty great snake...Someone would have seen it!"

"Hermione's answered that, too," Harry said.

Harry showed us what Hermione wrote on the piece of paper.

"Pipes?" Ron suggested.

"It's possible," I agreed."It could be using the plumbing."

"Remember what Aragog said, about that girl fifty years ago? She died in a bathroom?" Harry recalled. We nodded, remembering what had happened with that great big spider.

Man...got some stuff to tell to the others, especially Annabeth about this spider and "quest". Oh, she'll shiver at the spider.

Harry continued."What if she never left?"

"Moaning Myrtle," Ron and I simultaneously gasped. Harry nodded.

Suddenly, there was an announcement from a familiar voice.

"All students are to return to their house dormitories at once. All teachers to the second-floor corridor, immediately," we heard Professor McGonagall's voice.

We decided to head to the second-floor corridor. Loud footsteps were heard as we reached the second-floor corridor.

"As you can see, the Heir of Slytherin has left another message," Professor McGonagall stated. We stopped, pressing ourselves against the wall to hide our bodies from the professors."Our worst fear has been realized. A student had been taken by the monster into the Chamber itself. The students must be sent home. I'm afraid this is the end of Hogwarts."She sighed. We heard some sniffling.

Our eyes widened, looking at each other.

"So sorry...Dozed off..." Professor Lockhart excused himself."What have I missed?"

"A girl has been snatched by the monster, Lockhart," Professor Snape said."Your moment has come at last."

Professor Lockhart's eyes bulged out."My m-moment?"

Professor Snape sneered."Weren't you saying just last night that you've known all along where the entrance to the Chamber of Secrets is?"

"Well, that's settled. We'll leave you to deal with the monster, Gilderoy," Professor McGonagall stated."Your skills, after all, are legend."

"Very well." He smiled."Ah, I'll just be in my office getting, um, getting ready." He turned around, heading to his office.

"Who is it that the monster's taken, Minerva?" Madame Pomfrey asked.

Professor McGonagall shook her head."Ginny Weasley." I noticed Ron's and Harry's jaw dropped."It seemed like Bianca was trying to save her, but Ginny Weasley was already taken away...She was found in the first-floor girls' lavatory." My jaw dropped too.

Bianca?! No way! She was supposed to be taking a nap!

"She's in the Hospital Wing already?" Professor Snape asked.

"Yes, Madame Pomfrey and I managed to get her quick into the Hospital Wing before anything could've harmed her more."

We watched them walk away, leaving the scene. We noticed the red writings on the wall.

"'Her skeleton will lie in the chamber forever,'" I read.

"Ginny..." Ron whimpered."Oh...poor Bianca..."

How am I gonna tell this to their parents now...

No One's POV

The sixteen-year-old boy stepped foot into the airport. Many people were passing him, going about their day.

His nose wrinkled."Filthy muggle airport..."

He continued walking, trying to search for something. More like search for someone. His eyes scanned everywhere. The shops...the cafes...the benches...the people...the girls...

Where was she?

He passed the girl's restroom, glancing inside. His eyes widened, spotting a girl inside this ice cube looking thing. He peeked in closer, taking a full look at the frozen girl.

Dark brown hair. Pale skin. Lily flower. Normal clothing. Coffee brown eyes. Shocked expression.

"Peculiar, actually..." He smirked."Looks a bit like him..."

The boy swiftly entered the girl's restroom without looking around for any muggles. He walked closer to the ice, examining the girl's state.

Did this figure appear recently? There has been no commotion at all.

"How...is it possible?"

He pressed his hands against the ice, but he pulled back. It was too cold. It was possible to get frostbite by touching it for more than thirty seconds. He stared into the girl's frightened eyes. He knocked on the ice and smiled.

"Hard." He dropped his hands from the ice."Perhaps could use some heat to melt you." He pulled out his wand."Or...perhaps use you as one of mine. It's not like people are ever gonna find you..."

Footsteps were approaching into the restroom.

"Perfect timing..."

He stared into the mirror, watching the woman enter. She noticed him and the frozen girl.

She jumped back, gasping."W-what?!"

"Avada Kedavra!"

There was a flash of green light in the restroom. The woman laid dead on the floor. There was a hiss as the boy casted another spell on the frozen girl. A hole was burnt, meeting against the skin of the girl's wrist.

Physical barrier. Ice. Green Fire. Scar

One of his eyebrows rose, staring at the new mark. He pointed his wand at the frozen girl."And to let me live longer..." He casted a disillusionment charm on the girl.

The scar continued stinging.

Bianca's POV

I gasped, begging for air. I sat up, panting. My scar was itching and burning like crazy, so I clawed at it. My scar was hurting at its most.

What was that dream...Was that really me? Was that really how I got this scar?

I looked around, seeing the Petrified students. Hermione was still laying in her bed, still looking like stone.

Wait...Was I Petrified?

I looked around my bed, seeing flowers, cards, and candy. On both of my bed sides, there were two familiar redheads. My face softened. Fred and George were sleeping on both sides of my bed.

Were they waiting for me?

"Oh! Miss Bianca! You're the first to wake up!" Madame Pomfrey exclaimed, heading towards me."How do you feel?"

I stared at her."Oh, uh...I feel fine?" I watched the twins stir in their position.

Fred slowly opened his eyes, taking a look at me. His eyes widened."Bianca!" He crushed me, wrapping his arms around.

"Uh, let go," I squeaked, struggling out of his grasp.

However, as I pulled away from Fred, I bumped into George, waking him up. He smiled, tackling me as well.

"I know you guys missed me a lot, but please consider my situation for hugging!" I yelped.

George stuck his tongue out."Never!"

"It seems like you've awakened, Bianca," I heard a familiar voice spoke up.

I released Fred and George, looking up to see the familiar man with those bright blue twinkling eyes that were behind his half-moon spectacles. He still looked the same with the silver hair and beard of his, as well as his purple long robes that touched the floor. I smiled, trying to contain my tears.

I bet he got back his position as headmaster of Hogwarts!

I jumped out of bed, running for him."DUMBLY!"

He caught me, chuckling."You feel a bit heavier than the last time I carried you."

I made a face, laughing. I nestled my head into his neck, letting his hair and beard hide me despite the warmth he was radiating."I missed you, Dumbly," I whispered into his ear.

"Wow...and you allow Dumbledore to hug you?" Fred scoffed.

George shook his head in disappointment while I stuck my tongue out at them.

Saffron's POV

After rescuing Ginny and flying with Fawkes, Dumbledore's phoenix, to escape the Chamber with a clueless Lockhart, we gave Dumbledore a visit to retell our adventure.

I shivered. The Chamber of Secrets scared me the most. It was dark...and underground... I hate it. However, when we told Dumbledore about it, he didn't even expel us for breaking a dozen of rules. He is granting us special awards instead!

The next day arrived, and we were all in the Great Hall eating dinner. All those who were petrified were supposed to be released today. However, I haven't seen Bianca or Hermione yet.

I pointed my fork at the pork chops in front of me."This is really delicious!" I exclaimed.

Harry laughed."You've said that three times now, Saffron."

"Look!" Neville called to our attention. We looked at him."It's Hermione and Bianca!" Neville exclaimed. We turned our direction to the entrance of the Great Hall, seeing the two smiling girls enter.

They spotted us, smiling wider. They began running towards us, and so did we, leaving our seats. Immediately, Bianca rammed into me.

"You're okay!" I yelled, quickly pulling away from her.

"And I'm glad you're okay as well!" Bianca said, giving Ron and Harry quick hugs.

Hermione hugged me. I noticed she and Ron didn't though.

"Uhh...um..." Ron cleared his throat."Welcome back!" They shook each other's' hands instead.

Hermione smiled."It's good to be back! Congratulations you three! I can't believe you solved it!"

Harry turned to Ron and me."Well, we had loads of help from you." Ron and I nodded in agreement."We couldn't have done it without you two either," Harry confessed, looking at Hermione.

She smiled."Thanks."

Bianca's POV

Well, to be honest, I shouldn't be praised. Hermione deserved it. She was the one creating the Polyjuice Potion and the one trying to search for anything in the library.

There were tappings on the glass, and everyone looked up at the professor's table.

"Could I have your attention, please?" Professor McGonagall spoke up.

Everyone was silent, and we five went to our seats. I sat next to Ginny and Saffron. I smiled at Ginny, who smiled back.

"You okay, Bianca?"

"Never better, Ginny," I whispered."Are you?"

She nodded."I'm sorry."

I smiled, giving her a hug. I quickly pulled away."It's alright, Ginny." However, she still looked guilty."It's okay, Ginny. You weren't yourself at all."

We watched Dumbly rose from his seat."Before we begin the feast, let us have a round of applause for Professor Sprout and Madame Pomfrey, whose Mandrake juice has been so successfully administered to all who had been Petrified," Dumbly announced, resulting in cheers and claps."Also, in light of the recent events, as a school treat, all exams have been canceled."

We looked to one another."Yes!" We heard everyone exclaimed. I heard this, especially from Ron and Saffron.

Hermione frowned."Oh no!"

I chuckled. The clappings and cheers died down as the doors to the entrance of the Great Hall opened, revealing our familiar giant friend.

"Sorry I'm late!"

I turned to the others."It's Hagrid!" They nodded.

They had told me that he was sentenced to Azkaban.

Really...It wasn't him that caused these attacks!

He began walking down the aisle."The owl that delivered my release papers got all lost and confused. Some ruddy bird called Errol."

Ron, Ginny, Fred, George, Saffron, and I exchanged looks, knowing about the poor owl, and we snickered to one another. Harry laughed, remembering the owl who had crashed against the window.

Hagrid stopped next to us, and we looked up, smiling up at him."And I'd just like to say that if it hadn't been for you, Harry, Ron, and Saffron, and o' course, Hermione and Bianca, I would uh...I'd still be you-know-where," he whispered."So...I-I'd just like to say 'Thanks.'"

Harry stood up, smiling."There's no Hogwarts without you, Hagrid."

We looked at each other and smiled more. Dumbly began clapping. Soon, I followed, standing up. It led to everyone clapping. Hagrid was near to tears, and I ran to give him an embrace. Soon, everyone followed, giving the giant a hug.

"Okay...I-I need to get out," I squeaked.

"Nope! Never!" I heard Fred and George yell.

"Keep hugging!" I heard Saffron's voice.

"Saffron!" I whined.
