A/N Okay so I had the idea to merge Twilight and DC together in a way I haven't seen done before.

Summary: It's been seven years since the Cullens left Bella in NM. The Cullens haven't tried to find or contact her and had accepted that she has moved onto a normal, human life, as they intended.

Bella never forgets them, but also eventually decides to actually have a life. She goes to college as distraction and focuses so much energy into it that she becomes a clinical psychiatrist in almost half the time it usually takes. She decides to intern at Arkham Asylum, where she meets the Joker, becomes like him and develops an intense hatred for the Cullens. She becomes obsessively in love with Mistah J.

After years of gangbanging with The Joker, getting thrown in prison and escaping, the government has decided they've had enough and call in the best medical professional in the country, Doctor Carlisle Culllen, to hopefully rehabilitate her, and use her to bring down the Joker himself.

Will Bella stay loyal to the Joker and attempt to get revenge on the family that left her destitute? Or will they actually be able to bring her back to sanity before the Joker finds her?

So basically, in this story, Bella is Harley Quinn. Not sure if I should continue or not but I'll post a couple chapters and if they get positive reviews ill continue.

Carlisle's POV

I walked through the door of our new home, as I always after working the late shift, and sighed. Esme was immediately at my side patting my back.

"How was work, dear?" she asked, taking my bag and laying it gently on the ground.

"Not very interesting. Nothing surprises me anymore."

She nodded and sat down next to me on the sofa. We recently moved to Jeneau and we were still settling in. Alaska seemed like the best place to go next. We were in France for a good year and decided to come back to visit the Denali's. Once we discovered that they would be moving on, we settled.

"Where is everyone?" I asked after a brief pause.

"Alice, Emmett and Rose went hunting a few hours ago. Jasper went out to do some chores for Alice-"

"You mean shopping?" I laughed.

She nodded, smiling. I love her smile. "Of course."

"Edward?" I asked, looking at the wall.

"He said he was going out for some space to think." She looked away as well, and I knew why.

It has been seven years since we left Bella and Forks behind. Seven years that he had been resisting the urge to go back. Seven long years that he's spent moping around, avoiding conversation and sinking deeper into depression.

The first year was the worst. He left without so much as a note, only calling to check in on us every few months. It took a lot of convincing from Alice and Esme to get him to return. I, myself, always thought that being away might be best for him. Esme, however, was overwrought with grief and I couldn't bear to see her that way.

I sighed again.

"Anything the matter, dear?" Esme asked, pressing her body against my own.

I nuzzled my nose in her hair and breathed in her sweetly scented perfume. "Nothing in particular. It's just that life has become tedious once again."

Being on this earth for as long as I have, things were bound to become tedious. They once were. The years following the completion of my family were extremely mundane.

After meeting Bella, everything once again became interesting for all of us. Something new. Something different. Now that she's no longer in our lives, everything seems even more mundane than it did before her.

Esme seemed to sense what I was thinking, as she always did.

"I still strongly believe they were mates, Carlisle. He should have stayed."

"It's his life, Esme. He did what he believed would be best for her."

"It affected all of our lives," she countered. "It's still not too late. If he decided to, he could still find her."

"She's human, Esme. After a while she must have realized we weren't coming back, and moved on to do human things. She's probably left Forks, gone to college, gotten a good job and possibly found someone new to be with. She may even be married, or have children at this point." I looked into her beautiful eyes. "It's too late. She has a life to live, too. If he had come to a realization a few years ago, perhaps there may have been a chance. But not anymore."

Her eyes filled with sadness. "It's so hard to accept, Carlisle. I love him like my own child and to see him in so much pain everyday…"

"Edward will find someone, my love," I tried to assure her. "Maybe not anytime soon, but eventually he, too, will move on."

I didn't believe the words as they left my lips, but it appeared that she did. I was glad. I didn't want anyone to worry about Edward. He may look like a teenager, but we all knew he was a grown man who was capable of adjusting and taking care of himself.

Just then, my cellphone buzzed in my pocket. I kept it on vibrate so as not to interrupt me at work, but our ears heard it clearly.

I gently moved away from my wife's embrace to get it. I checked the caller ID.

"Is it work?" Esme whispered. She was used to having me leave to go to the hospital at random times.

I shrugged. "It says Private Number."

"Answer it. It could be important."

I shook my head. "If it was very urgent they would have called directly from the office. And if it's anything less than an emergency, I'd much rather be here with you."

She smiled. We sat together in silence as the vibrations went on. Once they finally stopped, I checked the phone again.

"No texts. It was probably nothing." I looked up at the TV. A news report was showing but the volume was off.

"I hear the two people that escaped from that mental institution last week killed an entire ring of gangbangers in Chicago yesterday," Esme mused, looking at the screen.

The report was based in Chicago, so I assumed it was retelling the same story.

"Oh, yes?" I asked, making conversation.

I felt her nod. "The man got away, left the girl at the crime scene. She apparently shot and killed several policemen before being apprehended by a vigilante and taken back into custody."

I wondered how psychologically damaged one would have to be to go through all this trouble.

"This has been going on for a while now, isn't it so?" I asked.

"A good few years," she confirmed. "They're always caught yet somehow they always escape."

"Seems like they need better security at the institutions."

She nodded in agreement.

Just then, my phone began buzzing again. The same private number. Our conversation couldn't have taken more than a minute. Who was it that was so desperate to get a hold of me at this time of the night?

"Answer it, Carlisle," Esme insisted, standing up. "I'll be upstairs."

She was gone.

I clicked the green button and put the phone to my ear.

"Hello, this is Doctor Carlisle Cullen," I introduced myself. "With whom am I speaking to?"

"I know who you are, Doctor Cullen," I stern, female voice echoed on the other end of the line.

"Alright, who am I speaking to, if I may ask?"

"That's not your concern at this moment," she said. "I need to discuss something with you. Urgently."

"It is a bit late, don't you think so?" I laughed and feigned a yawn into the phone. "Could this not wait until morning, by any chance?"

"No."

There was a long pause and I decided to finally speak.

"Alright... What is the urgent matter?"

Another pause.

"I hear you're the best doctor in the country," she said, maintaining a monotone voice.

I coughed and feigned bashfulness. "I'm not sure who you've heard that from, but I'm far from that."

"You don't need to give me any fake modesty." I was taken aback by that. "I have a request. It's extremely confidential, but you're the only person that I believe could help me."

I sighed, becoming more confused. "What is the request?"

"The government is grasping at straws, trying to keep the country running smoothly. It's not easy trying to keep up. There are a few… special cases that we, unfortunately, don't have the capacity to deal with on our own. We've brought in experts, who have tried and failed. We're hoping you could put an end to that trend, Doctor."

"Listen," I interrupted, "I honestly have no idea what you're talking about. You're a part of the government?"

"One of it's most exclusive members." She sounded cocky. "As I was saying, we need someone who can help us. There's been a staggering rise in criminal activity for the past few years, as you're probably aware of if you keep up with the news. The main culprits are a couple of people who are both demented and, as many believe, too psychologically damaged to be rehabilitated. Most of the crimes in relation to gang violence are at the hands of these people. We believe that if we somehow stop them, the gang violence will plummet. That would, of course, make the government very happy."

I remembered the news story from Chicago.

"If I agreed to help you, what exactly would I be agreeing to?" I probed. This intrigued me, but I wasn't going to hastily agree to work in close proximity with the government knowing how much I have to lose should they keep my identity on file.

"We have one of the culprits in custody now. After a mere five hours she had killed five guards and put two in the hospital. We need someone brave enough to come in and take over. A medical professional who has specialized in psychiatry would be best."

"I don't mean to question your motives," I started, "but why hasn't the government decided to give her the death penalty?"

I strongly disagreed with the death penalty as a concept, but I was curious. If this person posed so much of a threat to the government, why would they not just get rid of her?

"We have our reasons. The first being extreme curiosity. There's a reason she's like this and we intend to study her. Also, her partner works in almost the same way as she does. She may be more fearless and psychotic than he is, but he's certainly more of a threat to civilian lives. He's smarter, more practiced. If we can figure out who she is, we can figure out how to stop him." She paused. "At least, that's what we believe."

"Why did you decide to find me? There are plenty better psychiatrists out there."

I could almost hear the smile in her voice. "We have. Most of them are dead."

Now, I was interested. The sheer curiosity of it, partnered with my passion for difficult patients, overcame me.

"What do I do and how do I start?"

I could hear the smile again. "Take the first flight to Seattle tomorrow morning at 10am. I'll email the location of the prison we are keeping her in to your personal email address and you will meet me there. Once inside, ask for Waller. They will bring me to you."

"I have work. Is there any way to push this to a later date? I have a family as well," I told her.

"Oh, we know," she said. "We will send in your report of absence to your workplace in the morning. Your family will need to accompany you tomorrow as we will have agents come to Alaska to get your house ready."

At this point, I was thoroughly confused. She knew about my family, where I stayed, where I worked. However this should surprise me. She did know my phone number.

"What do you mean 'get my house ready'?"

"The girl will be staying with you, of course, to make for an around the clock, thorough examination." I heard her chuckle. "If this is more than you can handle, Doctor, we can find someone else."

I sighed and looked up to see Esme on top of the staircase. How long had she been watching me?

"Doctor Cullen?" I heard again.

I cleared my throat. "Not a problem. I can handle this case." I paused. "And I'll make sure she is rehabilitated as well," I added.

"If you do manage to survive, and above that get us the information we need, the government will make sure you are properly awarded for your efforts."

There was a long pause again.

"Tomorrow, 10 o'clock flight to Seattle. Make sure to check your emails."

The phone cut off.

I removed it from my cheek and checked the call log. Empty. The last call on record was a call from the front desk at the hospital at 9am.

"Did you hear?" I asked Esme, not looking up from the phone.

"We're going to Seattle."

I looked up and smiled. She didn't try to fight me on this. By the look on her face, she already knew I was fully dedicated. I checked my watch. 11pm.

"I'm going for a quick drive," I told her. "When the others come home-"

"I'll tell them to pack," she interrupted.

I nodded and grabbed my keys.

I wasn't sure where I was going, but I needed some mental preparation. I turned on the radio in the car. Every channel was reporting the day's events, and every channel seemed to include the story of the gangbangers who were recently killed.

What have I gotten myself into?
