Daddy's Little Cannibal: First, let's all give a huge round of applause to Ms. Bronze because without her and her amazingness, I would not have had any ambition to work on this story. Second, let's bow our hats to the Showtime show "United States of Tara" that gave me this idea. And thirdly, let's review this new story that the amazing Bronzehairedgirl620 has written with me. :)

Bronzehairedgirl620: I'm so psyched about this story; I don't even think you understand how much. DLC has come up with the most amazing plot, and I'm only doing my part in trying to keep up with her excellence. It's brilliant.

So read, enjoy, and review!

Summary: Isabella Swan has multiple personality disorder and has let Edward Cullen, an aspiring psychiatrist, do a case study on her and her multiple personalities. Collaboration between Bronzehairedgirl620 and Daddy's Little Cannibal, dark and funny. B/E

Worlds Collide

I put the car in park outside of Isabella's house. It would be a lie to say that I was excited to do this case study with her. It's not that I didn't like Isabella, because I did. I found her extremely smart, intelligent, funny, witty, she had everything that any man could ever ask for in a woman, but unfortunately, her "alters," as we decided to call them, weren't as charming as she was.

"Please don't let it be Victoria today." I begged aloud as I got out of the car.

Victoria was one of Isabella's most…extreme alters. Isabella had somehow managed to create an alter that wasn't human, even though Isabella was as human as they come. The first time I ever met Isabella and her family, Victoria had decided to pay us a visit. The memory was clear in my mind.

I had rang the doorbell to the house, excited that it was my first day meeting the person that I was going to spend the next year studying. I had heard rumors and read articles of multiple personality disorder (MPD) but never actually witnessed it firsthand. I was ignorant to believe that it was equivalent to someone that liked to play dress up a little too much.

Isabella's father, Charlie Swan, answered the door and invited me in. He introduced me to Isabella's mother, Renee Swan. and Isabella's close friend Alice Brandon. They led me to the TV room where Renee fed me stale cookies and watered down milk. I asked her where Isabella was, I was excited to finally meet my first patient.

The family fell silent. Alice let out a strangled giggle behind her small hand. I looked around the room in bewilderment. "Where is Isabella?" I finally asked again when I realized that no one was going to answer.

Renee opened her mouth and then closed it. "Isabella isn't here today." She said slowly, shooting glances at her husband.

"But I was told that Isabella would be here today. You must have known-"

"Bella's here." Alice interrupted me. "As in her body's here, but Bella decided that she needed to take a vacation, so Victoria took over for her."

"I don't understand." I looked away from the small girl to Isabella's parents. I shook my head to show that nothing that Alice was saying was making any sense to me.

Charlie sighed. "I'll get her for you." He pushed himself off the chair and walked up the stairs. Renee followed after him, mumbling something about how he might need help.

It was then that I realized that this wasn't someone that liked to play dress up a little too much and I might had found myself in a possibly dangerous situation. I tried to convince myself that my professor would never make me do something that would get me hurt, but the doubt was starting to overpower my logic.

"Hi Victoria." Alice called at the stairs.

My head shot in the direction of the staircase. It was impossible for me to restrain the gasp that had built in my chest. Isabella, or Victoria, was incredibly beautiful. She had long brown hair that curled at the ends, her skin was unbelievably white, and every time she stepped into the sun that was let in by an open window, the light would reflect the glitter that she bathed in.

I stood up and held out my hand for her. She was taking her time walking down the stairs, her back arched when she saw Alice and me. Her face held a tight grimace. When she finally reached the bottom step, her foot caught on her long dress and she fell forward. I rushed to her aid, the manners that my mother and father taught me kicking in.

"Are you okay?" I asked her as I tried to pull her to her feet.

Her eyes widened when they saw me, but instead of blushing or acting like nothing had happened like a normal person would, her lips curled over her gums and she let out a loud hiss. A real hiss. A hiss that could be compared to a cat or any other animal that hisses.

She jumped to her feet, mumbled something in Latin and rushed to the side of the house. Her hands holding up her long skirt.

I looked at Alice for support.

"She thinks that she's a vampire." She told me as if she was telling me that the sky was blue.

My eyes widened from the news. "She's not going to try to eat me, is she?" I asked. The image of such a beautiful creature lunging at me with her hands out like claws and her teeth bearing was clear in my mind.

Alice giggled. "No, she's a vegetarian. She only eats animals."

The sound of a dog crying out in pain echoing from the kitchen made me jump. Alice's face dropped and she pushed herself off of the couch.

"Don't eat Rufus, Victoria!" She screamed as she ran in the direction that the dog was crying.

It took a lot of convincing from Isabella's parents and my mentor to make me go back there.

I soon started to visit her twice a week over a three month period. It didn't take me long to get to know and eventually befriend most, not all- it's hard to befriend a vampire, of her alters. She had six of them, each one just as different as the other. There was the vampire, the neat freak, the foreigner, the rebellious teenager (I think she just turned sixteen), the forty-year-old biker (he intimidates me), and of course the real Isabella Swan.

I only got to meet the real Isabella once. It was after I told B, Isabella's rebellious teenager alter (I'm not bragging, but I think B has a crush on me), that I was going to be living with them for a few months.

It was nice to finally meet the real Isabella. She was quiet, unlike most of her alters, she stared at her hands a lot, and when she smiled, it was like the whole room brightened up. I couldn't imagine anyone like her wanting to hide behind a mask. I told her this, many times during out session. I just really hoped that she took what I said to heart.

"Please don't let it be Dale either." I made one more final plea before I knocked on the door to my new home for the next three months.

"Ah, Edward. Come in," Charlie said, trying to sound cordial, but I could hear the strain in his voice as I walked through the door.

"Hello, Mr. Swan." I said, trying to listen for any indication of who I would be meeting with today.

"Bella isn't here today," he said, cutting straight to the chase by answering my unspoken question. "But I need to have a word with you before you see…her."

I couldn't help but notice the way he avoided whoever she was at the moment. As if it embarrassed him. "Sure," I replied, shrugging out of my jacket.

Charlie led me over to the small sofa, his posture stiff as he frowned at the floor. I waited mutely, not sure of what he wanted to say.

"I need you to help Bella," he said, his tone softer than before. "This has gone on long enough, and it needs to end. She's throwing her life away."

I furrowed my eyebrows. "I'm not sure I understand," I frowned. "You make it sound like…"

I wasn't sure what I was trying to accuse him of, if anything.

"Bella has always been…imaginative. Always playing dress up, always wanting to create her own worlds. But this pretending has lasted for too long. It might be my and Renee's fault, for allowing her to remain in these dreams, but we can't change the past."

I stared at him. "What you're saying is that you don't believe Multiple Personality Disorder is real." I summarized, repressing my grimace as I saw him nod.

"Yes."

I sighed, stretching my legs out in front of me. "Mr. Swan, I will do everything in my power to get your daughter back," I said. I didn't want to do anything to upset him. "May I see her?"

Charlie nodded grimly, shaking my hand. "Good luck."

I hated the way he made it sound like I was walking to my death sentence but ignored it, carrying the few bags I had to the kitchen. I could see Alice from where I was standing, but whoever had taken over for Bella was nowhere in sight.

"Hello Edward," Alice said, noticing me lurking in the doorway. "Would you like something to eat?"

I shook my head, biting my tongue from asking any questions. "No, thank you."

"God damn it," I heard a voice growl from behind me. I turned around to see Bella's physical presence, although there was a different light in her eyes. She narrowed her eyes at me behind her glasses, crossing her arms over her chest.

"How many times have I told you to take off your shoes before you enter the house?" she snapped, pointing at my loafers. I looked down, hoping I hadn't tracked in anything, which would only upset her more. I knew this Bella – Emily, as she liked to be called. Any object out of place, any speck of dirt or mud within a ten- mile radius and she went ballistic, cleaning and mopping like no tomorrow.

"Hello, Emily." I said, extremely grateful that I had memorized the names of each alter. I wasn't sure what would happen if I mixed them up.

She nodded curtly in acknowledgement. "Shoes. Off. Now."

I inhaled deeply, trying to calm myself. "I'm sorry," I apologized, wanting to stay on her good side as I pulled them off and walked back to the front door, setting them by the welcome mat.

"Oh, Edward, you're here." Renee smiled brightly at as she walked down the stairs with a bucket filled with cleaning supplies.

I smiled back at her. "Hello, Mrs. Swan. Getting started on spring cleaning early this year?" I nodded towards the cleaning supplies in her hand.

Renee sighed. "Emily is back, as I'm sure as you can tell." She gestured to the shoes that I was setting by the front door. "Do you want me to show you where you'll be staying,"

I nodded. "Please."

She led me up the stairs, the wood creaking under our weight as we walked down the hallway.

"This is Alice's room," she said, pointing to a closed door. "Across the hall is Bella's, and next to that is the bathroom. You'll have it to yourself, because Alice and Bella share one."

"Alice lives here?" I asked. Renee nodded somberly, continuing to walk.

"She's decided to stay with Bella while you're doing your…research."

I nodded, following her down to the end. A window was open, letting in some fresh air and Renee turned to the room on the right, swinging the door open.

"You'll be staying here," she said. "Fresh towels are on the dresser, and feel free to help yourself or ask for anything you need."

She excused herself a minute later after explaining everything I needed to know. I sat my bags down on the bed, pinching the bridge of my nose.

This was going to be difficult, although I knew that coming in. It was my first case and I wanted it to go well, but it was waking up and not knowing who would be sitting at the breakfast table. There was the real Bella, the one I wanted to get to know the most, but she rarely graced us.

The one I found easiest to get along with is Marie, Bella's French alter ego. I still hadn't figured out if she spoke the language fluently, if at all, but her accent was pronounced. I met her when I had walked out in the backyard, one day. She was sitting on a chair wearing a beret, drinking a cup of strong expresso, and humming along to a French CD while she chewed on a crepe.

I dumped the contents of each bag onto my bed, watching as they spilled onto the floor and rolled under the bed.

"Great," I said as I heard someone, probably Emily, thumping up the stairs, muttering to herself. I did my best to gather up everything I had dropped, but I wasn't fast enough.

"You better get those clothes off the floor before I do it for you," Emily warned as she waltzed past the door, eyeing me. I groaned, falling on my back as I heard the vacuum start somewhere down the hall.

This was going to be a long three months.
