A/N: I apologize for throwing in another Twins-Who-Lived story in here, but I really hope to shake things up a little with this one.

I looked up flower names to use, and I decided on Cassia, before I settled on Holly, because of the H and Y with double letters, but then I decided that there was to many H names and changed it back to Cassia.

Elizabeth Gillies is the face-claim for Cassia Potter.

Chapter 1: Missing Glass Mishap

"We are not alone,
It's always darkest before the hope,
You and I, we're not alone."

Prayers for the Damned – Sixx:A.M.

The sun was coming up and Cassia Potter was still asleep on the cot in the living room.

"Up!" a woman screeched in the hallway, "Get up!" She rapped on a door, "Now!"

Cassia woke up with a start as her aunt, Petunia, knocked on the cupboard door to wake up her twin brother, Harry. Aunt Petunia knocked on the door again, and screeched once more, "Up!"

Cassia heard her aunt walk and then a minute later, Aunt Petunia was roughly shaking her. "Get up. Now. I want you to start on the eggs and don't you dare let them stick together, again."

"Yes, Aunt Petunia," muttered Cassia.

Aunt Petunia walked away.

Cassia rolled over on the cot, right onto her stomach, and she thought about the odd dream she had, which was a lot of green light. She couldn't understand it better than Harry, who also had the same dream. She figured that the light came from the car crash that she and Harry survived when they were babies. The result was Harry getting a lightning bolt scar over his right eyebrow and their parents dying, relegating them to live with their aunt, uncle, and cousin.

She looked at the pictures of Dudley that was on the mantelpiece. There was Dudley riding a bike, riding a roundabout at the fair, playing a computer game with his father, Vernon, being hugged and kissed by his mother. The mantle piece held no pictures of the other two kids that were living there.

"Are you up yet?" Aunt Petunia demanded in the hallway, sounding like she was trying to speak to the both of them at once.

"Nearly," replied Harry.

"Almost, Aunt Petunia," called Cassia still laying on the cot.

"Well, get a move on." Aunt Petunia ordered from the hallway, again trying to sound like she was speaking to the both of them at once. "I want you both to look after the food. And don't you dare let it burn. I want everything perfect on Duddy's birthday."

Cassia sighed at the mention of Dudley's birthday.

"What did you say?" Aunt Petunia snapped.

"Nothing…" the Potter twins said at the same time.

Cassia wasn't sure how she forgot her cousin, Dudley's birthday, but somehow she did. After all, it was constantly thrown in her face by her aunt, uncle, and Dudley.

She slowly sat up right as her aunt walked in. Aunt Petunia looked at Cassia with pursed lips and then she walked back in the kitchen. Cassia flopped back on the cot.

There was thumping from the stairs and then, a loud voice called, "Wake up, Potters! We're going to the zoo!" It was Dudley who was running up and down the stairs.

Cassia couldn't help but think that it was Dudley's exercise for the rest of the year.

Dudley then started jumping on the stairs.

No, that's his exercise for the rest of the year, Cassia thought.

Dudley then ran the rest of the way downstairs.

Before Cassia could even get up, Dudley grabbed the cot and tipped it, so she fell out of the cot and hit the ground. He ran down the hall, pushed Harry back in the cupboard and kicked the door shut, all before Cassia can even get up off the floor.

She got up, folded up her thin blanket, and then folded the cot. She grabbed her very thin pillow, the blanket, and the cot, and went to the cupboard. Harry opened the door and looked at Cassia, "I'll get breakfast ready." There was the sound of Petunia singing to Dudley about his birthday. He grabbed Cassia's cot and set it against the wall, under a shelf. "I don't know why you bother getting dressed when we both know that they're going to drop us off with Mrs Figg."

Every year on Dudley's birthday, they were dropped off at Mrs Figg's house, while Dudley and a friend of his, were taken to adventure parks, hamburger bars, or the cinema. Mrs Figg was a mad old lady who lived two streets away. For some reason Mrs Figg's house smelled of cabbage and Mrs Figg had them both look at photographs of all the cats that she owned.

Cassia shrugged, "If I don't, Aunt Petunia's going to make me get dressed until she deems me presentable."

"Oh, right," Harry said.

"Yes," replied Cassia.

Cassia walked in the cupboard, set her blanket and pillow on Harry's cot. She started looking in the bin bag underneath a shelf. She was looking for a semi-nice looking skirt to wear and took out a knee-length black skirt that had a see-through film covering it and a purple shirt.

Some probably found it odd that Dudley had two bedrooms, while she was forced to sleep in a cot in the living room and Harry got a broom cupboard under the stairs. Well, when the Potter twins were younger, they had shared the cupboard under the stairs and shared a blanket. It was then that Cassia found out she was a blanket hog. When they started getting bigger, the cupboard got cramped, so Cassia was moved out into the living room and then forced into a shed.

For some reason, Aunt Petunia was fond of Cassia looking presentable. Cassia figured that it was her aunt's way of looking 'normal' to the outside world. Once a year, Aunt Petunia would bring home a bin bag stuffed with second-hand clothing from second-hand shops. Cassia figured that it would look strange if she walked around wearing Dudley's overly large hand-me-downs. So, she got second hand clothes while Harry got hand-me-downs from Dudley.

The Potter twins had black hair and green eyes. Cassia's slightly wavy black hair went to her elbows and was messy; she had a thin face with a slightly pointed chin. Harry's black hair usually stuck in the back and he wore circular glasses.

Cassia hurriedly got dressed as she heard Aunt Petunia singing about Dudley's birthday. She went in the kitchen where Harry was simultaneously working the eggs and bacon. She noticed more pictures of Dudley and then she noticed that the table was almost hidden beneath Dudley's birthday parents.

"Brush your hair!" their uncle, Vernon, snapped when Cassia entered the kitchen.

"Yes, Uncle Vernon," Cassia muttered. She didn't own a brush, because her aunt and uncle would never spend money on hair care products for her.

Uncle Vernon gave Cassia look of disdain, probably at her hair, before Cassia went to the stove and started working on the eggs, like Petunia told her to. She looked at the table to see that Dudley got the new computer, the second television, that racing bike that he wanted. Cassia wasn't sure why he wanted the bike, because he hated exercise, unless running up and down the stairs, or tipping the cot over while she slept in it, punching people (mostly Harry), and chasing after her and Harry, counted as exercise.

Dudley was a very large boy, with a large pink face, not much neck, small, watery blue eyes, and thick blond hair that lay smoothly on his thick, fat head. Petunia claims that Dudley looks like a baby angel, but Harry says that Dudley looks like a pig wearing a wig.

Then there was Cassia, who was small and skinny. She figured that it was because she mostly hid in the cupboard with Harry.

"Hurry up," ordered Uncle Vernon.

"Yes, Uncle Vernon," replied Cassia and Harry. Cassia grabbed the frying pan and hurriedly scooped eggs on her uncle's plate. Harry put the plates on the table, which seemed difficult.

To Uncle Vernon, Dudley demanded, "How many are there?"

"Answer him, girl," Uncle Vernon ordered.

"Thirty-six," Cassia said as she made plates for herself and Harry.

"'Thirty-six?'" repeated Dudley, "But that's two less than last year!"

"Darling, you haven't counted Auntie Marge's present," Aunt Petunia rushed in to calm down Dudley. "See, it's here under this big one from Mummy and Daddy."

"All right, thirty-seven then," said Dudley, going red in the face. Cassia and Harry looked at each other, before they started wolfing down their food at the kitchen island, as Dudley worked himself up in a tantrum. He was prone to flipping tables in his tantrum throwing state.

"Here's what we'll do," Aunt Petunia said quickly, seeing the tantrum building up. "We'll buy you another two presents while we're out today. How's that, Popkin? Two more presents? Is that all right?"

Dudley thought for a moment, which looked hard. Finally Dudley said, "So, I'll have thirty…thirty…"

"Thirty-nine, sweetums," replied Aunt Petunia, cooing at Dudley.

"Oh," replied Dudley, sitting down, and grabbing the nearest parcel.

"Crisis averted," Cassia whispered to Harry, who grinned.

"Little tyke wants his money's worth, just like his father," said Uncle Vernon, chuckling. He ruffled Dudley's hair, "'Atta boy, Dudley!"

Cassia rolled her eyes at that.

At that moment, the telephone rang. Aunt Petunia went to answer it, while Harry, Cassia, and Vernon watched Dudley unwrap his presents.

Cassia went to start on the dishes as she watched a racing bike, a cine-camera, a remote control aeroplane, sixteen new computer games, and a video recorder get unwrapped.

Cassia was just scrubbing a plate when Aunt Petunia came in, looking angry and worried. She said, "Bad news, Vernon. Mrs Figg's broken her leg. She can't take them." She jerked her head in Harry and Cassia's directions.

Dudley's mouth fell open in horror while Harry and Cassia looked at each other.

"Now what?" said Aunt Petunia, looking furiously at both Potter twins, like they had intentionally hurt Mrs Figg.

It was going to be a whole year before they had took at Tibbles, Snowy, Mr Paws, and Tufty again.

"We could phone Marge," suggested Uncle Vernon.

"Don't be silly, Vernon, she hates them," replied Aunt Petunia.

Well, we're not entirely fond of her either, thought Cassia.

It wasn't unusual for the Dursleys to speak of the Potter twins as if they weren't there.

"What about what's-her-name, your friend—Yvonne?" suggested Uncle Vernon, sounding a little desperate.

"On holiday in Majorca," snapped Aunt Petunia, as if insulted at the idea of dropping the twins off on her friends.

"You could just leave us here," Harry suggested.

Cassia nodded. She wanted to finish a book, maybe watch something on the television, or maybe even catch up on some sleep.

Aunt Petunia made a face as if she swallowed something sour, and snarled, "And come back and find the place in ruins?"

"We won't blow up the house," replied Harry.

"Or destroy any of your property," added Cassia. The broken picture wasn't their fault, but they were blamed for it anyway. Dudley had thrown a shoe at her, and she ducked at the right moment, which had hit the picture and caused it to fall back. Somehow, Cassia had gotten blamed for it anyway.

"I suppose we could take them to the zoo and leave them in the car…" suggested Aunt Petunia slowly.

As if we won't destroy the car too? Cassia thought.

"That car's new, they're not sitting in it alone," said Uncle Vernon.

That's when Dudley began to wail loudly. Harry and Cassia knew that if Dudley screwed up his face and wailed, Petunia would give him anything he wanted.

"Dinky Duddyums, don't cry, Mummy won't let them spoil your special day!" Aunt Petunia cried, hugging Dudley.

"I…don't…want…them…t-t-to come!" Dudley yelled, between fake heaves. "They always sp-spoil everything!" he gave the twins a nasty grin, through the gap in Petunia's arms.

The doorbell rang and Aunt Petunia frantically said, "Oh, Good Lord, they're here!" She looked at Cassia, "Get the door, girl!"

Cassia went and answered it. She forced a smile at Piers Polkiss, who sneered at her. He was a scrawny boy, with blond hair, and had a face that reminded Cassia of a rat. Mrs Polkiss was a tall blonde woman, who looked a lot kinder than Piers. She smiled warmly at Mrs Polkiss, "Hullo, Mrs Polkiss." She stopped smiling as she looked at Piers. In a colder tone, she said, "Piers." He was usually the one who held people's arms behind their backs while Dudley hit them. Cassia smiled up at Mrs Polkiss, "They're in the kitchen." It was obvious because of Dudley's fake wailing. She led them to the kitchen and entered. Once Dudley spotted Piers, he stopped his wailing at once.

Mrs Polkiss looked around and placed her hands on Piers's shoulders, "I hope that the kids have a good day at the zoo."

There was no choice; the Dursleys had to take Cassia and Harry.

Thirty minutes later, Cassia followed Harry outside to the car.

When Harry opened the door to the car, Uncle Vernon slammed it shut. He held up a finger at them. "I'm warning you two," he put his face close to theirs, "I'm warning you two, now. Any funny business, anything at all," he looked at Harry, "And you'll be in that cupboard," he looked at Cassia, "And you'll be in the shed," he looked at them both, "till Christmas."

Since two kids couldn't fit in the cupboard, Cassia was placed in the shed, whenever she and Harry both got punished.

Cassia nodded, swallowing, "Yes, sir."

"We're not going to do anything…honestly," responded Harry.

"Get in the car," Uncle Vernon ordered, ignoring them.

Cassia was stuck in the third backseat while Harry, Piers, and Dudley were in the front row, near the back door. Being stuck there wasn't that bad. At least she didn't have to put up with Piers pinching, elbowing, pulling her hair, or shoving her into the door.

It honestly wasn't hers or Harry's fault weird things happened to them.

Uncle Vernon complained to Petunia as he drove. He complained about: people at work, the twins, the council, the twins, the bank, and the twins, which was some of Vernon's favourite subjects to complain about.

"…roaring along like maniacs, the young hoodlums," Uncle Vernon complained as a motorbike overtook them.

"I had a dream about a motorbike. It was flying," said Harry.

Uncle Vernon nearly crashed in the car that was in front of them. He turned around, his face very red and he shouted, "Motorbikes don't fly!"

Dudley and Piers sniggered at that.

Harry loudly said, "I know they don't. It was only a dream."

When they got to the zoo, families were already there. There was a lady in the van selling ice-creams.

Dudley shoved his way to the front just so he can get to the van.

"What do you want?" the lady asked, smiling at the family and Piers.

"Two large chocolate ice-creams," Uncle Vernon stated gruffly.

The lady got the chocolate ice-creams and noticed the Potter twins, who were standing a little bit behind the Dursleys and Piers. "And what do you two dears want?"

Cassia quickly started to say, "Can I please get a strawberry—"

"They'll get a lemon ice lolly," Uncle Vernon stated talking over Cassia.

The lady frowned, but got the lemon ice lollies for the Potter twins anyway. She looked apologetic as the two were ushered away, and Cassia said 'thank you' over her shoulder.

When they got in the zoo, the Potter twins were ushered around the exhibits to see what Dudley waned to see.

Cassia couldn't focus on the exhibits because she was watching the families around them. She couldn't help but feel pangs of jealousy at the sight. She wondered what she and Harry had done to get stuck with the Dursleys. She wondered why her parents had to get in a car accident. She wondered what life would be like if her parents were alive. She imagined that they would have their own rooms, with actual beds. She wondered what her parents were like. She was jostled out of her thoughts by Harry nudging her and she looked at him, "What is it, Harry?"

"That looks like Dudley," Harry whispered to Cassia. He was pointing at a gorilla, who was scratching its head.

Cassia snickered, "Except that it's not blond."

Piers purposely shoved Cassia with his shoulder and she stumbled forward, dropping the ice lolly right into the exhibit down below. She cringed at the waste of money, "Ah, hell."

Harry stepped forward, glaring at Piers, who walked alongside Dudley. They were laughing as they walked with the Dursleys.

Cassia grabbed Harry's arm. "Harry, please. He's not worth it. He's not worth getting locked in the cupboard till you turn eighteen."

Harry looked at her and sighed, "You're right, Cassy."

They hurried on, making sure to walk a little behind the Dursleys, so the Dursleys wouldn't be associated with them.

Cassia didn't get to enjoy the exhibits because she kept getting distracted by thoughts of her parents and what her family life would be like if they weren't with the Dursleys.

"I'm hungry!" declared Dudley loudly, jolting Cassia out of her thoughts.

"He always is," Cassia muttered to Harry.

Harry grinned at that. It wasn't always every day that his sister insulted someone. She was to kind for that; although she insulted people in her head. Being rude wasn't in her nature.

They went to the zoo restaurant and the Potter twins ended up with the cheapest hamburger on the menu. Harry ended up with a single hamburger and Cassia got small chips to go with it, which she split with Harry. The Dursleys didn't starve her, but they usually gave her a little bit more food than Harry, so the Dursleys wouldn't look odd if the teachers at school noticed an 'undeveloped' girl walking around.

When Dudley threw a tantrum over the fact that his knickerbocker glory wasn't big enough, Uncle Vernon had gotten Dudley a new one, but allowed the Potter twins to eat the first knickerbocker glory.

After lunch, they went to the reptile house. It was cool and dark, with lit windows all along the walls. Behind the glass, all kinds of lizards and snakes were crawling and slithering over bits of wood and stone.

Dudley and Piers wanted to see huge, poisonous cobras and thick, man-crushing pythons. Dudley found the largest snake in the exhibit. It could've wrapped its body twice around Uncle Vernon's car and crushed it into a dustbin, but the snake was asleep.

Dudley stood with his nose pressed against the glass.

Harry mimicked Dudley causing Cassia to smile and giggle.

"Make it move," Dudley whined at Uncle Vernon.

Uncle Vernon tapped on the glass, and ordered, "move." The snake didn't budge.

Dudley hit the glass and shouted, "move!"

"It's asleep," Harry snapped, as the snake slept on.

"Yeah, let's leave it alone," Cassia said.

"This is boring," Dudley moaned and shuffled away, leading his parents and Piers away.

Harry and Cassia looked at the snake. Cassia looked the plaque, seeing that it was a Brazilian Boa Constrictor, which was bred in the zoo.

"I wouldn't be surprised if it had died of boredom," Harry said.

"Yeah, its only company is people drumming their fingers on it to disturb it," Cassia said.

"It's worse than having a cupboard as a bedroom," said Harry. "The only visitor is Aunt Petunia and you."

"And spiders," Cassia pointed out. She wasn't a fan of spiders, and she was sure that the spiders weren't a fan of her, either. She tolerated their presence and she was sure that they barely tolerated her. "At least you get to visit the rest of the house. It's a little bit better than having the living room. I have to endure Dudley flipping my cot nearly every morning."

"True," said Harry.

Cassia looked around, "I'm going to go look at the lizards." She went to a different exhibit and looked at the lizards. One was standing on a stick and wasn't moving. She wouldn't be surprised if the lizard had died standing up.

"Cassy!" exclaimed Harry.

Cassia jumped and she could've sworn the lizard did too. Harry nearly ran into her and Cassia looked at him. "What is it?"

"You got to see what the snake is doing," Harry said, grabbing her arm and dragging her back to the snake.

"I think it was a Brazilian Boa Constrictor," Cassia said.

Harry and Cassia went to the tank. Harry looked at boa constrictor and the snake made a strange hissing noise, and then shook its head.

"Dudley! Mr Dursley! Come and look at this snake! You won't believe what it's doing!"

The shout from Piers made Harry, Cassia, and the boa constrictor jump.

"Move it, you!" Dudley ordered, shoving Harry to the side.

Harry stumbled back into Cassia and they both fell to the ground.

Cassia got up, groaning and wincing. Dudley was pressed up against the glass and then everything went to hell.

One second the glass was there and the next it was gone. Dudley fell headfirst in the water and the snake hissed at them as it passed by, and Cassia ran as someone shouted, "Snake!"

There were screams and Cassia was barely out of the reptile house when someone roughly grabbed her upper arm. She started screaming and was silenced by a low, menacing growl that came from her uncle. She knew that growl well and she was dragged inside. Uncle Vernon had her by the arm and had Harry back the collar of his shirt. The sight was probably something to behold.

But the scene right in front was even more of a sight to behold.

Dudley was trapped in the snake tank as he pounded the glass and Aunt Petunia pounded the glass and was shrieking about how they were going to get him out.

Cassia couldn't help but smile at the sight and giggle. She was silenced when Petunia looked straight at them, as if it was their fault. It couldn't have been their fault…right?

They stood outside the reptile house for nearly ten minutes, before Uncle Vernon, Aunt Petunia, and Dudley emerged. Dudley had a blanket draped over his head and looking extremely pale. Petunia had her arms around Dudley. The Potter twins were dragged over to the zoo director's officer where they stayed for nearly an hour.

Aunt Petunia and Uncle Vernon were given strong sweet tea and the children were given biscuits, but Harry and Cassia didn't even get them. Dudley seemed well enough to devour most of them, before he started gibbering again.

Uncle Vernon started threatening to sue and the zoo director did everything in his power to appease the Dursleys. Uncle Vernon and Aunt Petunia eventually settled on all-year round passes for all them. Cassia knew that the Dursleys would mostly likely give a member of Dudley's gang hers and Harry's passes.

When it was time to leave, Uncle Vernon remained calm. It was a bit stressful, because Cassia knew that her uncle was going to go off on her and Harry, while Dudley cowered in the blanket. After Piers was dropped off, that was when Uncle Vernon started sputtering and speaking incoherently.

They were barely out of the car, when Uncle Vernon grabbed the back of Harry's collar and roughly grabbed Cassia's upper arm. While Aunt Petunia led Dudley in the house and to the kitchen, Uncle Vernon dragged them in the house. He pressed them against the stairs.

"I demand an explanation," Uncle Vernon demanded. His face was red, "Now!"

"I don't know what happened. Honest," Harry said.

Uncle Vernon looked straight at Cassia.

"I'm sorry, Uncle Vernon. I really don't know what happened either," Cassia said. Uncle Vernon tightened his grip on her upper arm, as he glared at them. "One minute, the glass was there—"

"And the next, it was gone," Harry finished, "like magic."

That was the magic word; Uncle Vernon released Harry, opened the cupboard and shoved him in. He locked the door and opened the grate of the cupboard. In a menacing voice, he said, "There's no such thing as magic." He closed the grate and then dragged Cassia through the kitchen and into the backyard. He opened the shed and shoved her in. "Just like I told your brother, there's no such thing as magic." He closed the door and locked it.

Cassia sat down on the extra cot that was placed there for when she got in trouble. She didn't know why strange things happened to them, but they did, and she wasn't sure why they got in trouble for them.

That was one of the rules in the Dursley household. One rule was not to ask questions and the second was that when one Potter was in trouble, the other Potter was, too.

"There's got to be more to life than on Privet Drive," Cassia said. "There's a world out there and I'm stuck in a shed, while Harry's stuck in a cupboard."

A/N: I know that Cassia is barely a character, but it's just one chapter.
