Okay, this is an idea that my younger sister gave me. She loves Life with Derek and Charmed and she thought it would be cool if a crossover was published, so here it is! I'm very nervous about this, so it would be totally awesome if you guys would review, (sigh) even if it is to tell me I suck. ;) But seriously, constructivecriticism is great! Plus, you don't need to watch Charmed to get the story; I explained everything. Hope you enjoy!

October


It was another ordinary day in the Venturi/McDonald household. The weather matched the moods of the two eldest children of the estate. It was September, so it was freezing, and to top it off it was raining. Derek Venturi and Casey McDonald had been snipping at each other since breakfast and it was nearing lunch. To say that everyone else was becoming annoyed would be an understatement. As soon as Nora – who had control of the remote – heard her daughter and step son bring their argument in from the kitchen, she muted the television and turned to her husband.

"Honey," she sighed when she caught his attention, "I'm hungry and I don't feel like cooking anything." She motioned over to Casey and Derek in significance, "Why don't we round up the kids and go to that restaurant that just opened on 6th street." As Nora subtly ordered him out of his seat, she stood up from her own and motioned for George to do the same.

George got up and walked over to the coat post while Nora called up the stairs for their other three children while the two feuding step siblings sat in the seats he and Nora had vacated. They were still barking insults at each other and didn't notice the rest of their family don their coats and open their umbrellas, preparing to face the storm outside rather than the one inside the house. As he followed his youngest step daughter out into the rain, he saw Lizzie roll her eyes. He silently agreed. It was moments like these when he was glad that he and Abby had done what they'd done when their three kids were still in diapers.

"Derek!" Casey screamed, standing up once more. She stormed past him and up the stairs to her room. She slammed the door and threw herself onto her bed. She hated that he made her act so unprofessional. If Casey was anything, it was professional. She rolled over onto her back and glanced at her walls. They were covered in pictures of Nora, Lizzie, and herself, along with a few of the Venturis. No one ever questioned why all the pictures her and her mother and sister were in together, Casey was never younger than 16. In a few she could pass as 15 and maybe 14, but she knew the truth.

She stared at a picture of her and her pseudo mother. Nora's arm was draped around Casey's shoulders and they looked a mess. Their hair was mussed and they had dust and grime all over them. Nora was beaming but Casey had on a tight smile. The picture had been taken on the day they were moving into the Venturi household. Casey put on a bittersweet smile. She had only been given her wings three months prior and now she had to live with first charge. And a rude one at that. She had gone through a huge ordeal and then she had to put up with an insensitive jerk.

An idea suddenly popped into her head. She quickly stood up from her bed and went over and locked her bedroom door. She went back and sat in the middle of her perfectly made bed and closed her eyes, concentrating. She was still getting the hang of this orbing thing and she needed all the concentration she could get.

Casey could see her destination in her mind's eye. It was a large field, broken occasionally by a smooth, polished stone. The leaves would be falling around that time of year, and the grass would be brown and crunchy due to the drop in temperature. She could see the wind winding through the trees, making the leaves rustle. Casey focused all of her power on feeling the wind on her skin and the sound the grass would make under her feet. And then she could feel and hear it.

She opened her eyes and suddenly she was sitting on the ground in her hometown's cemetery. Standing up, Casey brushed the dirt and grass from her jeans. She shoved her hands into her pants pockets and wished she had thought to bring a jacket. Casey shuffled her feet in a direction she knew too well for her liking. Lizzie had brought her here soon after it had happened to explain things more clearly. Casey still hadn't understood. Now she did.

Casey made the necessary twists and turns before finally laying eyes on it. Her headstone. It still made her uncomfortable to think of herself as dead. But there it was. A nice polished rock, just for her. She looked down and sighed. It still had her name on it.

'What were you expecting?' She thought to herself. 'For it to have all been a dream?' She sighed again. Her epitaph looked back up at her.

R.I.P

Casey Meadows

Beloved daughter and friend

It was all carved into the stone, and she remembered tracing the words with her fingers as Lizzie told her what had happened.

She and her father were at the store picking up flowers for her mothers grave. She had died when Casey was born, so Casey didn't have any memories of her. She and her father lived in a fairly small town and everyone knew everyone, so when someone new entered the store, it caught everyone's attention.

No one could see his face as it was obstructed by the hood he had pulled over it. Some people, like Casey and her dad, tried to go about their own business and not make a scene, while other people stared blatantly at the newcomer. He avoided eye contact with everyone and fidgeted nervously at one of the small displays at the end of one of the isles.

Casey was concentrating on which flowers they should purchase, when the hooded man's voice rang out.

"Everyone get on the ground!" He shouted, and Casey's head shot up along with everyone else in the store. The man was swinging a gun around with no one target. Casey felt her father's hand on her shoulder, gently pushing her down. She grabbed his hand and tried to bring him with her but he stayed standing.

Her father put his hands in front of him to show the strange man that he wasn't going to do anything. "Look, son, I know that you think you're doing something that seems like a good idea, but if you put the gun down and walk out of the store now, we won't do anythi –" He was cut off by a loud banging sound. There were scattered screams and yells but Casey's was the loudest as she saw her only living family member start to fall to the ground next to her. She shot up from her position on the ground and went to catch him; to ease his fall. What she didn't expect was the hooded man to get the wrong impression and fire two more bullets straight into her chest.

That was the last thing she remembered before waking up Up There. That's when another man in a long white robe came up to her, Lizzie in tow, telling her that Lizzie would explain everything. And Lizzie did explain everything.

Casey tried to blink back tears as she looked away from her headstone and towards the place where her father was buried. She still hadn't been to see his grave yet and he had died almost eight months ago.

She was about to head towards her father's headstone which was laid next to her mother's, when she heard a faint ringing in her head followed closely by Derek's voice calling her name. Casey sighed and glanced between her own grave and where her parents' lay. She would have to come back another day. She closed her eyes and pictured her room as Derek's voice sounded in her head again. As she landed with a loud thud on her floor, Derek started knocking at her door.

"Casey!" He called through the piece of wood between them. "Come on! I know you're in there!" He paused for half a moment, "Look, I'm making sandwiches for lunch and as a form of apology, I'm asking if you would like one?" He waited for an answer and he got one when Casey opened the door. He took in her appearance as she stood there in front of him. Her arms were folded in front of her and she had grass stains on the knees of her jeans. Her cheeks were tinged pink and her eyes were rimmed red. Her hair looked like she had been standing in the wind, but she wasn't wet and it was still raining outside. She even had a few tears straying down her cheeks.

Putting her hair off as either a strong air current in her room or she was lying down in a weird position, he really didn't care about that. What he did care about however, was why she was crying. He had only said that her hair looked like a rat's nest. It was one of the more innocent comments he'd made about her looks that day. Why did she cry over it?

"Why are you crying?" He asked worried that she was going to get him into trouble with his dad and Nora. There was a party at a member of the hockey team's house and the only way he was going to miss it was if the world was ending.

Casey's hands shot to her face as she quickly swiped away the few tears that sprinkled her cheeks. She didn't know that she had actually shed the tears that she thought were just threats.

"I'm not." She looked back up at him. "You were saying?"

Derek reached up and scratched the back of his neck nervously. "Yeah. You want a sandwich?"

Casey nodded and smiled. "That'd be great Derek. Thanks."

"Well, what do you want?"

"Hmmm." Casey considered her options. "I'll have turkey with mustard, please. But give me a minute to clean up. Okay?"

"Yeah, sure." Derek nodded and went on his way back down the stairs to prepare lunch. He heard Casey close her door behind him. He went straight to the refrigerator as he entered the kitchen. His head was still in the fridge looking for all the necessary foods, when he heard Casey walk up behind him. "Hey, Case. We have yellow mustard and honey mustard. Which do you want?" He expected a sigh and for Casey to shove him out of the way and make lunch herself. But what he got was a low growl as he was pulled from the fridge and thrown across the room.

There in front of him was a large scaly. . . Well the only name he could think of was monster. It looked like it was snarling, but perhaps it was a smirk. "Actually, I don't like mustard." Was all he said before he launched at Derek again. Derek managed to roll out of the way just before the monster landed where Derek had previously sat. He heard Casey's footsteps coming down the stairs, and all he could think was 'I have to get her out of here.'

Casey appeared suddenly and her eyes went wide. There was a demon attacking her charge in their kitchen. She didn't know how to deal with demons yet. She didn't know what to do, so she did the first thing that came to mind. She tore across the room and grabbed Derek's arm. Casey pictured the bench at the bus stop a few blocks away.

Derek saw hundreds of white and blue lights dance before his eyes as soon as he felt Casey's small hands wrap around his arm. The monster disappeared and suddenly they were no longer in the kitchen. He looked around and recognized the bus stop a few blocks down from the house. Derek was sitting on the ground in front of the bench and Casey was practically lying on top of him. The rain was still pouring down and even though they'd only been sitting there for a few moments, they were thoroughly soaked.

Casey scrambled to get off of Derek and as she stood she reached out a hand to help Derek up as well. Derek grabbed her hand and pulled himself up. He looked at the frazzled girl next to him as she ran a hand through her tangled wet hair. Casey was visibly shaking when she turned to her 'step brother'.

Derek pointed at Casey. "We've got some tings to talk about." He ordered and she nodded her consent and they trudged to the nearest diner.

---------------------------------------------------------------

Casey was trying to wipe the sticky table in front of her off so she could at least place her hands on the thing. She was studiously ignoring the boy sat in front of her. She had tried to call Lizzie but when the 'younger' girl didn't show up, Casey figured she would have to deal with this on her own.

Derek stared at Casey, blinking only occasionally. She hadn't said anything since suggesting the small diner they were now. It was nearly empty and the service was good and fast. They had agreed to talk after their food came so they wouldn't have any listeners when she explained what the hell had just attacked them.

Just when Casey was wondering what to say the waitress came and sat their food in front of them and asked if they needed anything else. Derek and Casey refused and she left the two 16 year olds alone. Casey looked at her plate and picked up a fry as she glanced up at Derek.

"Talk." Derek ordered when he saw her look up.

Casey narrowed her eyes as she swallowed her fry. "What do you want to know?"

Derek rolled his eyes at her avoidance, "What was that thing that attacked us?"

"That was a demon." She deadpanned. Derek's eyes widened and he was about to respond when Casey cut him off. "No, I'm not crazy. That was a demon. You are a witch. And I am your whitelighter." She popped another fry in her mouth.

Derek was at a loss. "What's a whitelighter?" He asked stupidly.

Casey gave him a soft smile. He'd given her an easy topic. "A whitelighter is a guardian angel for witches. I'm supposed to help you choose the right decisions and be here for you to talk to. Which considering how we treat each other, is pretty funny. There are . . . people that I 'work' for. The Elders. They appointed me as your whitelighter." She let out a small laugh. Derek looked stricken and confused. Casey decided that she should probably explain everything else because Derek didn't seem capable of talking. "You are a witch. A Charmed One to be exact. You, along with Edwin and Marti, will save the world. Probably more than once too." She added as an afterthought. She looked up from the sandwich she was about to bite into and stared at Derek for a moment. "Breath, Derek." She ordered softly.

Derek took in a deep breath and continued to stare at his step sister. If he hadn't seen that demon with his own eyes, he would have dragged her to an institution right then. Some of what she was saying was making sense. "So are you Ed and Marti's whitelighter too?"

Casey's eyes went wide and she coughed on her bite of sandwich. She took a sip of her water before setting him straight. "Oh, no! You're my first and only charge."

"What!" Derek said loudly. "I'm your first ever? I'm supposed to give up my life to save the world, and they made me your very first . . . ?" He paused, searching for the right word.

"Charge." Casey supplied, cringing. She didn't know he would take it this bad.

"Well I want to talk to whoever 'appointed' you. I want someone experienced to 'guide' me."

Casey narrowed her eyes and felt a strong need to defend herself. "Hey! You know, They had Lizzie train me, so I'm as good as any other whitelighter." Her eyes suddenly widened when she realized that she had ratted out the older whitelighter.

Derek's eyes widened as well. "Lizzie is one too?" Casey nodded. "Is Nora one?"

Casey shook her head, "No. That would be because Nora isn't our mother. And Lizzie and I aren't sisters. Lizzie died ten years ago, so she is actually 23 right now."

If possible Derek's eyes got larger and his eye brows shot to his hair line. "What do you mean 'died'?"

Casey took another bite of her sandwich. "You should eat before your food gets too cold." She told him, avoiding the subject.

Derek took a chunk out of his cheese burger and a small handful of fries for good measure and threw them in his mouth. "What do you mean 'died'?" He repeated around the food.

"That is disgusting." Casey said in distaste. "But, yeah. All whightlighters are dead."

Derek swallowed his food. "So you're dead?" He was hesitant to ask. This was already a lot to take in. He didn't even fully understand it. He really didn't know else to say to Casey after all her confessions.

"Yeah." She nodded, "I died about eight months ago, so I actually am 16. That's why Lizzie is training me. It's also why the two of us had to pretend to be Nora's daughters. Nora is one of Lizzie's charges and when she wanted to marry George. . . Well it would have been hard to explain a seemingly 13 year old always around when Nora doesn't have kids. Then I was brought in because you're the one closest to my age and we didn't even know each other. It was easier to pretend that I was just another daughter." Casey picked up another fry and bit into it.

Derek nodded. He understood now. But now he had another problem to ask about. "Do I have any powers?"

Casey nodded and held back a laugh. If he only knew. "Yeah. You have a power. But I'm not sure which. It depends on which ones your siblings have. They were given to you by the start of your bloodline. Her name was Marilynn Chase. There was a prophesy that three siblings – you, Ed, and Marti – that you would each get one of her powers. Her powers were strong and so will yours. She had the power to freeze time and blow things up, she could move things with her mind, and she could see the future."

Derek smiled. Finally some good news. At least no matter what, he'd get a cool power. "Do youhave any powers? Does Nora? What about my parents? Can I use my powers?" He asked in one breath.

Casey laughed, "Yes, Nora does have powers. She can read people's minds." At Derek's astounded face, she smiled even bigger. "How do you think she knows everything you're planning? Your dad can move things with his mind but your mom is a mortal. You can't use your powers because your parents bound them when you were a baby. That's all I know on that subject. They," She nodded up towards the ceiling, "didn't tell me much. They thought it would help us bond more, because you're supposed to talk to me about your problems. And last but not least, as a matter of fact, I dohave powers of my own. I can orb – that's how we got out of the house -, I can hear a charge no matter where I am, I can feel your emotions, heal everyone and thing – with the exception of myself -, and I can't die." She paused, "Well, I – all whightlighters – can die if they're hit with a darklighter's arrow."

Just as Derek was about to ask another string of questions, Casey's cell phone rang. She threw the fry she was holding into her mouth as she pulled the phone out. Glancing at the caller i.d, she saw it was Lizzie. She held up her index finger to indicate that Derek shouldn't talk and flipped the phone open.

"Liz?" She asked confused. "Why are you calling? I thought you were out with everyone else."

"Casey!" Lizzie shouted, ignoring Casey's questions. "I'm so glad you answered! We were attacked at the restaurant and we're on our way home now. Are you there?"

Casey's eyes were wide, and Derek was worried. "Liz! Don't go home! We were attacked there so I orbed the two of us out and I'm not sure if the demon is still there." She paused. "Actually, I'm going to orb over there now and see if I can sense it. And don't worry. I'll stay outside and I won't bring Derek."

Then Lizzie surprised Casey, "Actually, Case, you should bring Derek. Abby was murdered this morning. The Elders told me after breakfast, but I wasn't allowed to say anything. When she died Derek, Edwin, and Marti got their powers. That's why all these demons are attacking all of a sudden. If you leave him, he could get killed. And if you can't get out of there in time, Derek can help protect you. If he has a strong enough emotion he should be able to tap into that power."

Casey nodded, and then remembered that Lizzie couldn't see her. "Yeah, okay. Why don't you take the longer way home. At least if you get attacked there are more of you. I don't want Marti and Ed to fear their home."

"Alright." Lizzie agreed. "We will be home in twenty minutes if there are no detours. Bye." Casey said bye and the two whightlighters hung up.

Casey shoved her phone back into her jeans pocket and looked back up at Derek. He'd had wolfed down the remainder of his plate. "Come on. We've got to get to the house before the others." They got up to pay for their food and Casey turned to Derek as they walked out the door. "Oh, and now you do have your powers."
