A/N: I am so sorry I have to kill Derek in my story... As i am trying to include everyone in the story, the only reason I can come up with to get Cristina back to Seattle is Derek's death. And I know that some of you doesn't like Burke being an adulterer. But I promise! It is not going to last long! Just keep reading!

Chapter 4

"Hey." He pushed the door of the scrubbing room open, and leaned against the sink beside Cristina.

"Hey." She looked up briefly, gave him a smile, and continue washing her hands.

"So, I have saw something interesting when I came here. Seems like you brought one of the Seattle Grace's tradition here." Burke said while picked up a pack of sterile soap and played with it casually.

"What tradition? I bet that is not a good one."

"I just saw an intern and an attending walked out from an on-call room."

"Oh I know that is coming! Can't they just keep their pants on at business hours? It's not like they can't see each other after work! Crap, I sounded like Webber didn't I?"

"A bit, but you sound less frustrated than Webber, I guess that's because you were one of those interns that had been screwing attendings in on-call rooms." He was punched in the stomach by Cristina immediately. He laughed and grabbed some paper towels for Cristina.

"Oh and apparently your resident admires you a lot. He begin defending you before I even started asking how your work is going."

"Shane? He had been working with me since he was an intern. He and I are kind of like the relationship we had when I was an intern."

"Oh, does that mean you often hang out with him in on-call rooms? Cause as far as I can recall we used to do that when you were an intern." He stepped closer to her with his cocky grin on.

"Can you just stop thinking about sex for one second?" She rolled her eyes while drying her hands with paper towels.

"Yes, but not now, because that is one of the reasons for me to come here. To have sex with you." He leaned forward and placed a kiss on her lips. She giggles and pulls him into her office, locking the door and resuming what they started in the scrub room.

Lying on the couch, naked and gasping, she laid her head on his muscular chest. He freed one hand and started soothing her curls.

"I am going to Seattle on Friday. Wanna come?"

"For what?"

"It's Ellis's one-year-old birthday. I am her godmother but I had never saw her. And… it's the anniversary of Derek's death soon. I just think I should be with Mer on that day."

Burke's hand stopped its movement for a while. He then let out a sigh and whispered into her ear.

"I will go with you. I still cannot believe Shepherd had died for almost 2 years now."

"Me neither."

2 years ago, on one rainy dawn, Cristina was cuddling with Burke in her apartment in Zurich. They were having a moment of cozy until her phone rang.

"Damn it. Whoever calling me should better have a good reason to bother me." Cristina grumbled as she reached for her phone.

At the moment she sees Meredith's name flickering on the screen, she had a feeling that this phone call is not a good one. Something bad had happened.

"Hey Mer… Alex? Why are you having Mer's phone? What's going on?"

"She collapsed? Why? Hey you guys are surgeons!"

"Holy… Did you guys check with that hospital? Is there some kind of mistakes?"

"God… How is Mer now? Is she okay?"

"Of course… I will be on the next plane."

"Okay, keep an eye on Mer for me. I will be there as soon as I can. Bye."

Once she got off the phone, she froze at the spot she was standing and stared blankly out of the window. She took a few deep breaths before rushing to her closet, pulled out a huge suitcase and started packing.

"Hey… What's going on? Where are you going?" Her noises waked Burke. He put on a T-Shirt and walked to Cristina's side, revealed her shivering while throwing a black dress into her suitcase.

"What happened? Where are you going? And why are you crying? It's alright…" He hugged her in his arms, and tried to calm her down in order to figure out what is happening.

"Derek… Derek is dead. Derek Shepherd, McDreamy is dead!" She sobbed and told Burke the news.

"What? How?" Burke could not believe his ears. Not long ago he just heard from Cristina that he and Grey had become parents of two kids. And suddenly the next thing he heard about him is his death. How could this be possible?

"Alex didn't tell me everything in the phone. In fact, only Meredith knows what happened, but she fainted in front of everyone, so no one knows exactly what happened. Anyway I am going to Seattle now. Can you book me a plane ticket please?"

"Yeah sure… You know what? I am coming with you."

"You are?"

"Yes. Derek is my friend. Although we haven't seen each other in ages, he is still one of my good friends. I have to attend his funeral."

The word funeral stimulated her tear glands, tears ran down her face again.

"I can't believe he died so suddenly. What should I say to Mer? I have no idea what to do… I sucked at coping with deaths. I laughed on George's funeral, and I skipped Mark's." Cristina rambles as she stuff her jeans into the luggage.

"I think she just need you to be there. Sometimes talking is overrated. If she doesn't want to talk, let her be." He gently combed her wild curls.

"Right…" She closed her suitcase, and turned around hugging Burke in her arms and say, "Don't ever die."

"Yes ma'am, you have told me that before." Remembering the same words had come from Cristina before, when Denny Duquette died, is mystically amusing for him.

"I mean it!"

"I know. I will try my best on that."

"And don't ever left me again."

"I promise I will stick around until you decided to get rid of me." Landing a soft kiss on her forehead, he releases her and went to book their plane tickets.

The flight to Seattle is not a pleasant one. Both of them could hardly close their eyes on the 13 hours flight. Burke looked at Cristina, and saw her staring blankly at the photo of Meredith, Derek and her holding an African baby on her phone. He sighed, and then raised the armrest between them in order to hold her hand. Her hand was cold, he grabbed her hand and began rubbing her hand between his palms.

"I'm okay. I just… can't believe that. Last week when I talked to Mer, Derek was till in DC. And all of a sudden he is dead. Is that a joke? No, I know Alex won't joke with these things. God, I can't even imagine how Mer is feeling."

"Hey… don't worry too much. Grey is very tough, she can get through this."

"You know… Maybe I should take Mer and the kids to Zurich? They can stay with me, take it as a vacation or something. Oh or I should stay in Seattle for a few months in case she need anything? What do you think?"

"I think, you should get some sleep now. And wait for Grey tell you what she wants." He pulled her into his arms, patting on her back to ease her tension. The two of them slowly fall asleep with their hands holding each other.

When the two of them woke up, they already arrived at Seattle. They didn't even bother to drop their luggage at the hotel first, as the both of them just wanted to arrive at Grey-Sloan immediately.

Parking their car at the familiar entrance, they can feel that the whole hospital is surrounded by sadness. It is another typical rainy day in Seattle, like the sky is sad for their loss too.

Burke stared at the hospital front door quietly, Cristina yanked his sleeve and said, "Hey, you can be nostalgic later, don't forget we are here for Derek and Mer."

He nodded at her and marched into the hospital with her. As they walked down the familiar hallways, memories rushed back. Every place is the same, but the people they used to see were no longer here.

"Grumpy! Hairball!" Jo was handing tissue to Stephanie at the nurses' station while they heard their nickname: a nickname that had never be used since Dr Yang has left. They turned their head around and saw Cristina and a tall, dark man walking towards them.

"Of course she would be here, she is Medusa's best friend!" Jo mumbles under her breath.

"Where is Meredith?" Once Cristina reached the two residents, she asked immediately.

"She was in room 2436, Dr Karev and Dr Torres are there with her." Stephanie sniffs as she answer.

"Alright." Cristina ran to Meredith's room after she heard the resident. Burke shook his head and asked politely, "Would you two mind looking after our luggage for a while? Thank you."

"What are you two doing here? Aren't you guys supposed to be in there staying with Mer?" Alex and Callie were standing outside Meredith's room when Cristina arrives.

"Oh thank God you were here Cristina!" Callie yelled as she gives her old roommate a big hug.

"What does that mean? Alex?"

"Mer kicked us out once she wake up. And she don't want anyone of use get into that room. But we think she might let you in. By the way, welcome back."

"Thanks, I am going in now." Cristina took a deep breath, and opened the door.

"I said I don't want anyone to talk to me!" Meredith shouted. She was lying on the bed, with her back facing the door.

"It's me Mer. I am here." Cristina said quietly. She cautiously walked nearer to the bed.

Meredith heard her voice, and turning her body so she can face Cristina now.

"Cristina." She murmured.

"Yes. I am right here. Whatever you want to say, whatever you want to do… I am here." Cristina sat down on a chair beside the bed, grabbing her best friend's hand.

"He is gone."

"I know."

"He is dead."

"I know."

"I have so many things I want to tell him. I haven't tell him goodbye. I haven't tell him I love him enough. He was supposed to get to DC yesterday, resign from the president's project and come back to us. And now he left us, forever, he is never coming back to us." Meredith busted into tears as she tells Cristina her feelings.

Cristina has no idea what to say to Meredith now, she hopped on Meredith's bed, and lied with her on the bed. It broke her heart to see her best friend crying over her dead husband.

The two women cuddled together on bed, giving each other support. Until a fuss began outside the room.

"What the hell?" Meredith snuffed as she asked.

"I will go check out what is going on. You stay here okay?" Cristina jumped off the bed and walks out to see what is happening.

Seconds after Cristina entered Meredith's room, Burke found the room. Both Callie and Alex were shocked to see him after almost ten years.

"Dr… Dr Burke?!" Callie is practically screaming. She thought she will never see this man again after he blew off his wedding with Cristina.

"Dr Torres, Dr Karev. It has been a long time since I last saw the two of you." He nodded to them in the typical Preston Burke way.

"What are you even doing here?" Alex does not sound nice or friendly, after all this man broke his friend's heart, giving her a hospital surely is not enough to undo the damages.

"Preston?" Another surprised voice came from the back. The three of them turned around and saw Dr Webber with an unbelievable face on and Dr Bailey with her mouth widely opened. Clearly none of them have expected to see him here too.

"Richard, Miranda, it is a pleasure seeing you two again." He smiled at his used-to-be superior and colleague.

"I don't remember inviting you here Preston, I thought you already stopped doing surgeries, since you gave your hospital to Yang." Richard was completely lost.

"Well, I still operates from time to time. But I am not coming here to do surgeries. I am here for Derek. I heard the news, and, as an old friend, I think I should come back to see him one last time."

"That's… very thoughtful of you. But where did you heard about that?"

"Well, I was sort of next to Cristina when she got the call from Karev. And she told me what happened."

"Whoa, wait. When I called Yang, I called her apartment's phone. How come you were 'sort of next to her'?" Alex was the only one that can sense that something's wrong. Burke did not expect anyone to think into his words seriously, he struggled internally whether to tell the truth or to distract them. But before he can decide, someone decided for him already.

"Why is he here?" Owen and Amelia were coming to check on Meredith. Once they stepped out from the elevator, Owen immediately saw the stranger among his colleagues. Although he never met the man, he knows exactly who he is: Preston Burke, the man who left Cristina at the altar, and took her away to another continent by offering her a job Seattle could never give her.

Rage and hatred built up in his body, and he couldn't control his desire to kick his ass anymore. He walked to Burke's front and punched him in his face.

"Owen?" "Owen!" Both Amelia and Cristina shouted out in shock and disbelieve.

"It is Seattle Grace after all." Bailey mumbles while shaking her head, disapproval of what just happened.
