*I do not own Harry Potter (JK Rowling) or Doctor Who (BBC)

**I want to have the next chapter up Thus. Anyway, keep showing support by 'faving' 'following' and 'reviewing'!

***I had this time travel fanfic idea with Rose, Scorpius, and James. Leave a review within the next TWO weeks letting me know!

"Harry," Clara said, "It's not your fault. You didn't do anything!"

Harry looked down at his meal. It was the Christmas Feast at Hogwarts, and Clara could tell that Harry wasn't in the spirit.

A few days ago, Justin Finch-Fletchley had been admitted to the hospital wing, and Nearly Headless Nick had been almost frozen. It didn't take long for students to start gossiping about Harry and his sorting. They were coming up with all different types of theories, though one kept appearing and lowering Harry's mood. They blamed Harry for the attacks, saying that he was the Heir of Slytherin, and he would release the monster from the Chamber of Secrets.

Ron pulled at some chicken. "Well, we're going to find out everything today. I know Malfoy-that slimy git- is the Heir! He has to be!"

Hermione rolled her eyes. "Ronald, we don't know that yet."

"You know what he said! You'll be next mudbloods!"

Clara shuddered. "Please, let's keep calm. I don't like Malfoy any more than you do. In fact I'm still serving detention because of him!"

Next to Clara, John silently picked at his food. Clara elbowed him in the arm. John quickly looked up. "Oh, yeah. Well, isn't that the reason we're doing this? I mean, using the polyjuice potion?"

Hermione nodded, "Yes, now we must discuss our plan."

Clara and John both smirked. "Plan? Plans usually end up going wrong. That's why I don't make them," Clara kidded.

Hermione narrowed her eyes, "Yes well, now I'm making the plan. Now, hush up!"

"Yes, m'lady…"

"Anyway," Hermione continued, "You two," she pointed at Ron and Harry, "should try to get some of Crabbe and Goyle's hair. They're supposedly Malfoy's best friends. I've already been figured out. But…" Hermione stopped and looked at John and Clara apologetically, "I only have enough for four people. One of you will have to sit this one out."

John leaned backward, "Me, I don't fancy turning into some stupid Slytherin. Maybe, if he were smart, but seeing as all of Malfoy's 'friends' are complete idiots, I'm out."

Clara crossed her arms. "Thanks." John simply smirked.

"Ok," Harry said, "It's decided. Though, who are you and Clara going to transform into?"

Hermione brought out two vials with hair. "I got this from Millicent Bulstrode. She's gone for the break, But I'll just say that I came back. And this I believe, is Pansy Parkinson's hair."

Clara felt a chill run down her spine. "Ok...I don't fancy turning into Pansy, but seeing as you brewed the Polyjuice Potion, I'll do Pansy."

Hermione nodded in agreement, and then pulled out two chocolate cakes. "I've filled these with a simple Sleeping Draught. Make sure Crabbe and Goyle find them, and eat them. Then, once their out, grab some hairs and meet me in the girls' bathroom, ok?"

Ron grunted, "Have you ever heard of a plan where everything could go wrong?"

John raised his hand, 'Yes, mine."

John and Clara followed Hermione to the girls' washroom. They saw the near-ready Polyjuice Potion which Hermione had brewed, with some help from John, in one of the cubicles. The potion looked nauseating, green and bubbly. Clara gagged at its sight.

Hermione wrinkled her nose as well. "Yes, it really is disgusting. But, if we are to find out whether or not Malfoy is the Heir, we must do this!"

John waited outside the cubicle, as there wasn't much space inside. Her frowned when Clara came out. "That potion smells worse than a sweaty Sontaran!"

"A what?" Clara asked.

John furrowed his brow, and shrugged. "Just something I read."

At last, Ron and Harry came. They carried the oh-so-precious hairs of Crabbe and Goyle. Ron went up to Hermione.

"They have got to be the most stupid people I have ever met!"

Hermione ignored him, and poured the potion into four glass vials. Ron's eyes widened when he saw the thick potion.

"That looks disgusting!"

"Believe me, it is," Clara answered.

"Ok," Hermione said, "now we have to put the hairs in." With a shaky hand, Hermione handed Clara the Pansy hair, and she dropped the Millicent hair into her potion. The liquid fizzed, and finally set to a ghastly, yellow substance. Hermione paled.

Harry and Ron did the same, and their potions ended up looking like bogey and mud. The two boys gagged.

"This is why I didn't participate," John said.

Clara rolled her eyes, and with drew a deep breath. She dropped her hairs into the glass bottle and watched as it bubbled and fizzed. Hers turned a murky brownish-pink. She took a quick whiff and gagged at the strong perfume scent. Alcohol.

"Wait!" Hermione exclaimed. "We should separate into different cubicles. Our clothes won't fit once we have drunk the potion…"

Clara nodded in agreement, she chose the cubicle opposite where the potion in the cauldron had been brewing. Clara sucked in a deep breath, hoping to not breathe in the horrid scent. She choked down the mixture, which left a burning sensation in her tongue. Clara belched and clutched her stomach. Immediately, there came a tugging sensation in her gut, and Clara felt her skin and body rippling. Clara shut her eyes closed.

After the feeling stopped, Clara peeked through. Clara felt a little more slender, and much paler. She pulled at her bangs to see that they were a dirt-brown. Even Clara's hands looked different. Clara shook all her thoughts out, she had focus on the task at hand. She quickly donned the Slytherin robes, which really didn't look that bad except for the fact that Clara was a walking image of Pansy Parkinson.

Clara left her cubicle and waited a couple seconds for Harry, Ron, and Hermione. Both Ron and Harry came out at about the same time, resembling Crabbe and Goyle down to the last freckle. Clara shuddered. She could feel the two boys gaping at her.

"You look hideous." Ron said.

"I know."

"Even your voice sounds different!" Harry declared.

Clara hadn't noticed it until now, but he was right. Her voice was now much more high-pitched. "Ugh..Just my luck!" Ron and Harry snickered, so Clara shot them a look. "You know, you guys don't look that great yourselves!" Clara glanced around the room. "Where's Hermione?"

"I-I don't think I'm going!" Hermione squealed from her cubicle. Ron started banging on the door.

"Come on, we need to go! I know Millicent's ugly…"

"No, seriously, I'm not going! You guys leave without me!"

Clara came up to the cubicle door. "Are you sure? Are you ok?"

"Yes! Now go! You only have 55 minutes left until the effects wear off!"

John looked at Clara and said, "Don't worry guys. I'll be right here. She's probably just sick."

Ron and Harry nodded hesitantly, but Clara pulled them along. They slipped off quietly into the corridors.

Clara and the boys walked about, trying to follow Slytherins to get into their common room. However, Slytherins are sneaky snakes, and they always lost the person they were following. However, they made it to the opening of the dungeon, where all the Slytherins seemed to appear from.

"Any ideas?" Ron asked. Just then, a girl with dark, curly hair appeared. Ron ran up to her. "Um… 'Scuse me, but we've forgotten the way to our common room."

The girl stared back for a couple of seconds. "Our common room? I'm a Ravenclaw!" She sighed and brushed passed him, glancing at him suspiciously.

Clara walked up to Ron with Harry. "Way to go, idiot!"

Ron flushed, "Sorry, sorry!"

They kept walking further into the dungeon. After fifteen minutes, Ron noticed something. "Hey!" He pointed, "There's one of those snakes now!"

The trio hurried toward the boy, but as soon as they saw him, their hearts sank. It was none other than Ron's brother, Percy. Ughhh…

"What do you think you're doing here?" Ron asked.

"That's none of your business. I'm a prefect. You're Crabbe, right?" Percy asked.

"What-oh, yeah…"

"Well, get off to your dormitories!" Percy snapped. "It's not safe to be out here this late!"

"You're here," Ron countered.

"May I remind you that I am a prefect? Nothing is going to attack me."

Then came a voice from behind Clara. "Have you been pigging out at the Great Hall? I've got something hilarious to show you!" None other than Draco Malfoy asked. He glanced at Clara and raised his eyebrow. "You're friends with Crabbe and Goyle?"

Clara stepped aside form her friends. "Oh, no! We just got stopped by this Weasley here," Clara said, nudging her head in Percy's direction.

Malfoy looked up at Percy. "Ah, I see. What are you doing here, Weasley?"

Percy's nose flared. "I am a school prefect! And I don't like your tone, Mr. Malfoy."

Malfoy sneered, and beckoned Clara, Ron, and Harry to follow him. Clara glanced back at Percy. He was a bit pompous, but he didn't need that from Malfoy.

Malfoy turned into the next passage, "That Peter Weasley-"

"Percy," Ron said. Clara felt like giving him a good thwack on the head.

"Whatever," Malfoy said, "He's been sneaking about. I reckon he thinks he can stop and catch the heir single-handedly." Malfoy chuckled. He then stopped at a bare, stone wall.

Malfoy turned in Harry's direction. "What's the password again?"

"Er- I"

Malfoy smirked. "I remember, pureblood!" The wall moved, to show what Clara guessed, was the Slytherin common room.

The room was gloomy, but definitely extravagant. Green lanterns adorned the room, and fires blazed with intricate mantle pieces. Clara bit her tongue from saying anything.

Malfoy lead them to a sofa by the fire. He urged them to sit. Clara made sure to sit in a completely different chair from Harry and Ron entirely. She was pretty sure Pansy wouldn't sit with them.

Malfoy looked at her. "You ok Parkinson? You haven't said a word."

Clara smiled fakely. "Oh, it's nothing. Just, you know, tired."

Malfoy seemed to scan her, but he shrugged it off and grinned. "I'll show you it in a second. My father just sent it to me!" Malfoy left for a minute and returned with a piece of a magazine.

Ron picked it up, and read out loud, "Arthur Weasley, Head of the Misuse of Muggle Artefacts Office, was today fined fifty Galleons for bewitching a Muggle car. Mr. Lucius Malfoy, a governor of Hogwarts, called today for Mr. Weasley's resignation. 'Weasley has brought the Ministry into dispute' Mr. Malfoy told a reporter. 'He clearly is unfit to draw up our laws and his ridiculous Muggle Protection Act should be scrapped immediately.' Mr. Weasley was unavailable for comment, although his wife told reporters to clear off or she'll set off the family ghoul on them."

Ron sat in shock for a moment. Malfoy was clearly losing his patience. "Isn't it funny?"

Clara let out a half-laugh. "Why, of course it is! Those Weasleys are complete idiots!"

Malfoy smiled again. "Of course it is. Arthur Weasley loves Muggles so much he should really just leave his wand and join them!"

Ron's- er Crabbe's- face warped.

"What's up with you Crabbe?" Malfoy asked.

Ron grunted, "Stomach ache, must've had something bad." Really bad, like Crabbe escence.

"Well, go up to the hospital wing and give all those mudbloods a kick for me, ok?" Malfoy's smile fell. "Honestly, I don't think those mudbloods should be in Hogwarts at all. Dumbledore's trying to cover it up. He really is the worst thing to happen to this school. He loved Muggles too much! Creevey wouldn't be in this mess had he just stayed in his filthy mudblood home!"

Malfoy made camera gestures with his hands. "Potter, can I have your picture? Can I have your autograph? Can I lick your shoes, your-"

"Ahem," Clara said.

Harry shifted uncomfortably. Malfoy noticed. "Seriously, what is up with you two?"

Harry and Ron stared at each other, but let out a late forced laugh.

Malfoy seemed satisfied. "I can't believe Potter! Hanging out with that mudblood Granger! And people think he's the heir!"

Clara coughed.

Malfoy, however, drone on. "I really do wish I knew who it was. I could help them."

Harry and Ron gaped, but Harry shook his head and when right for it. "You must know something about it!"

"Goyle, you know I haven't! How many times must I say it?" Malfoy quipped. "Father won't tell me anything, even about the Chamber! But, I do know it was opened about fifty years ago. And- a mudblood died. I bet it's a matter of time before another one does too. Personally, I hope it's Granger."

Clara clenched her fists. She looked up at Malfoy. "The person who opened the Chamber… Who was it?"

"Parkinson, I didn't know you cared!" Malfoy said, and Clara's heart started to beat faster and faster. "But," Malfoy continued, "The person was obviously expelled and sent to Azkaban."

Harry looked at Malfoy quizzically, "Azkaban?"

Malfoy sighed. "It's wizard prison Goyle! If you were any slower, you'd be going backward!"

Clara straightened her back. "So, Mal-Draco, what are you going to do about it?"

He shifted in his seat, "I'm not allowed to do anything. My father said to let the Heir do what it must, and get rid of the mudblood filth. But, I can't be wound up in any of it. Did you know, the Ministry raided our manor last week? They were looking for some Dark Arts stuff, but we have a secret chamber underneath the drawing room-"

"Ha!" Ron said with pride. Next to him, Harry blushed. Upon realizing his mistake, Ron did the same. But suddenly, Ron's hair started to turn red again, and his nose was lengthening as well. He was turning back into himself!

Clara looked at her hands, which were slowly tanning. Clara knew that they were in jeopardy. Ron and Harry both left, yelling, "Medicine for our stomachs!"

Clara got up as well, and Malfoy called after her, "Parkinson! And where are you going?"

Clara stuttered, determined not to face Malfoy, she winced, "Girl stuff, sorry."

She could hear the exasperated sigh escaping Malfoy's mouth. She ran even faster and caught up with the boys.

Ron looked like himself now, and he was panting. "We didn't learn anything!" They headed toward Myrtle's bathroom, slightly relived.

"Well, I'll write to my dad saying he should check under the Malfoy's drawing room."

"Yeah, good idea," Clara replied.

The trio came up to John. He smiled in Clara's direction. "Nice to see you not so hideous anymore."

"Are you saying that I'm hideous?"

"Yes."

This earned John a light punch on the shoulder. Clara looked around. "Is Hermione alright?"

John's smile wavered. "No," he answered.

"What?" Harry asked. He banged on her cubicle door. "Come out! We've got so much to tell you!"

"Go away!" Hermione shrieked.

Myrtle floated overhead, laughing. "Ooooh, wait 'til you see, it's awful!"

"You got Bulstrode's nose or something?"

The door unlocked, and a hooded Hermione stood in Clara's wake. Carefully, Hermione removed the robes she had been using to cover her face.

Clara gasped. Her face was covered in black fur. Her eyes were yellow, and she had two pointy cat-ears sticking up through her hair.

"It wasn't Mi-Millicent's hair!" Hermione cried. Clara came up to her, and patted her back to soothe her.

John crossed his arms. "She's been like that for an hour."

"Will you shut up?" Clara snapped. John held up his hands in sarcastic surrender.

Hermione wailed again. "M-Millicent must have a cat! The potion isn't supposed to be for animal transformations!"

Myrtle laughed again. "Oh, she'll be teased so much!"

"It's OK, Hermione. We'll bring you to Madam Pomfrey, she never asks too many questions…" Harry said.

Hermione shook her head furiously. "No, I'm not leaving! What if anybody sees me?"

Eventually, they got her out of the cubicle, but without some taunts from Myrtle. "Wait 'til everyone find out you've got a tail!"

Clara glared at the whiny ghost, but lead her friend to the hospital wing.
