Thanks for the reviews! I'm so happy that ya'll like this story! Song is So Jealous by Tegan and Sara

I don't want to be part of the problem
I try so hard to get roughed up
Fists on up, it looks that easy
It looks that way to me
It looks that way to you
But then there's you telling me I can
Then there's you screaming say something
I want the ocean right now
I want the ocean right now
I get so jealous that I can't even work
There I am in the morning
I don't like what I see
I don't know how it's become such a problem
Keep you up all night if I try to remain calm
How can they ask why I feel so angry
Do you see my problem if I never explain it
But then there's you asking me how long
Say something, it's taken me so long

Mark stumbled into his new office just after six AM. Without even turning on the lights, he walked directly to his desk and sat down his extra large cup of cappuccino on his desk. "I'm not in the mood, Derek." For the first time since he'd entered the room, he looked at his ex best friend was sitting on his leather couch, brooding, in the same clothes he'd seen him in the night before. He returned his attention to his desk to turn on the lamp that only gave light to a small portion of his desk, just enough for him to fill out paperwork.

"You always did know." Derek folded his hands, balancing his elbows on his knees, his eyes never leaving the solo magazine on the table in front of him.

"I've known you for 25 years, Derek. What do you expect?" Derek had come to make some resemblance to peace, but Mark's tone was making it very hard for him to do that.

"I expect you to stay the hell away from the love of my life!" Derek finally met Mark's gaze, as he stood up, running his fingers through his now tangled hair.

"Which one are we talking about here?" Mark rolled his eyes as he made his way to his chair behind his desk. He really wasn't trying to be an ass, but he'd been up half the night trying to figure out what the hell was going on. He'd spent two hours at the bar with Meredith after Derek ran out, and never, not once, did he get a definite answer. He knew Derek was going to ask a million questions, but he had no answers for him. Which was going to make this unfriendly encounter last much longer than he cared for it to.

"Didn't you come here for Addison?" Derek growled as he placed both of his hands firmly on the undecorated desk, his eyes darting directly into Mark's.

"Derek, Me and Addison.. Addison and I... we aren't the same people.. she isn't.. " Mark didn't know how to speak to Derek without sounding like even more of an ass. "You know what, I'm not having this conversation with you, Derek. It's none of your damn business. You might want to leave before I infect you with some disease." Mark repeated the words he'd heard whispered over and over in the hallways. "Sorry I ruined your trip with the lack of my presence! Good to know you can still blame things on me when I'm not around! You haven't changed at all!" Mark rolled his eyes as he took the top folder from a stack, and flipped it open.

Derek was slightly taken back by how quickly his words had found Mark, but he was too angry to care. "Oh. Are you trying to suggest everything isn't your fault? Because let's face it, that's a joke in itself!" Derek scoffed.

"Yeah Derek, the fact that you worked 24 hours a day, 7 days a week had nothing to do with the falling apart of your marriage. That is what we are talking about here, right? Or are we talking about all the space you took from Meredith after your divorce that led her to reconsider your relationship? Because I have to tell you, buddy, Neither of those did I have anything to do with!"

"Do NOT talk about my relationship with Meredith, Mark! You don't know ANYTHING about it!" Derek was furious.Sure he knew that it wasn't Mark's fault exactly, but he didn't need Mark to remind him- ever. He began to pace back and forth the length of Mark's desk.

"I do know what she told me last night after you ran out of the bar like a mad man!" Mark stopped working momentarily, and looked up at his oldest friend. "Listen Derek, this circle of hate we've got going here, it's nice. Really. If I didn't have a job, I would do this all the live long day. But It's not going anywhere. I don't have the answers your looking for. That's probably because you aren't even asking the right questions. Are you mad because I like Meredith or are you mad because it's your fault that I have a chance with her?"

"YOU DO NOT HAVE A CHANCE IN HELL WITH HER!" Derek's pacing of the floor escalated to an imitation of a run before Mark stood up and grabbed hold of his arm.

"Listen to me, Derek, and you better listen good. I don't know what you want to hear, and at this very moment, with you yelling and screaming at me in MY office, I don't care. You want answers? Here's a newsflash for you- you're talking to the wrong person! I want answers too, but you don't see me walking around this hospital like a mummy yelling accusations about things you THINK you know! Now get out of my office right NOW!"

Derek sighed in defeat as Mark released his grasp on Derek's arm. Derek nodded slightly, but instead of walking towards the door, he walked back to the leather couch and sat down. "You were my family, Mark."

"You'll always be my brother, Derek. But I know you, and I know that you are never going to forgive me for what happened back in New York, and if Meredith decides to give me a chance, I don't expect you to ever speak to me again. All of my life, I have watched you go from one serious relationship to another, never stopping, not once, to give yourself time to heal from the breakups. So when you did that after the divorce I was happy for you. I really was. You probably think that I'm out to ruin your life, but I'm not. All I know is that last night, I tucked in a grown woman into her bed with all of her clothes still attached, and left right afterwards, and still felt like it was a great night. I haven't felt like that in a LONG time. I won't let you take that away from me."

Silence overwhelmingly consumed the room, with only the sound of the idle grandfather clock ticking away the seconds to decipher that time had not stood still. Finally, Derek stood up and walked slowly back towards the desk. "You tucked her in?" His eyes were pleading for some sort of sign that everything would be okay. Mark had seem that look an uncountable amount of times.

"And then left." Mark confirmed with a small smile, remembering how content she looked.

"If she does, If she decides that... If she really wants to be with you, Mark, you better take care of her. I swear I will cut open your tiny brain from your very large skull and remove every nerve that gives you any hope of reproducing life before I effectively castrate you. Are we understood?"

"Yeah." Mark nodded, staring directly into Derek's eyes.

"Goodbye Mark." Derek frowned before turning around making his way towards the door.

Just as Derek reached for the door handle, Mark called out his name, causing him to turn around.

"Remember in college, when your goldfish died?"

Derek scratched his head in confusion, but nodded none the less, wondering where this was going.

"And you called your mom practically in tears, no matter what you say, Do you remember what she told you?"

Derek shook his head no, wondering how Mark remembered, and he didn't . Not that it surprised him, Mark always took the things his mom said to heart more than Derek did.

"She said that it's normal to mourn the loss of something you cherish, but the loss would be in vein if you didn't learn something out of it that would forever affect the way you live your life."

"What's your point, Mark?"

"When I lost you, I didn't know who I was anymore. I've always been Derek's best friend, my entire life, the silly sidekick who didn't care about anything. I.. I care now."

Derek stared sadly at Mark, before nodding his head and opening the door. "I don't." he whispered before walking out of the door, closing it behind him.

It was about half an hour after Derek left when Mark's pager went off, informing him he was needed for a consult for one of Addison's patients. "Excellent." he mumbled before pushing the chair back just enough from the desk to stand up. Grabbing his doctor's coat before closing the door, Mark made his way to the elevator to go to the 2nd floor, his office on the fourth. The door opened to an empty lift, causing Mark to smile slightly. He wasn't in the mood to listen to his name going round and round in the gossip mill of Seattle Grace. At least not until he'd actually done something to be gossiped about. He stepped onto it, immediately going to the back to lean against the railing. He was slightly surprised that he didn't walk in on a Meredith/Derek reunion of some sort, but happy none the less.

The doors opened on the third floor to reveal Meredith standing alone, causing his smile to broaden even more. "Morning Sleeping Beauty." he chuckled as she stepped onto the lift.

"I'm your intern for the day." Meredith tried her best to ignore the remark, but couldn't stop the small smile forming on her face.

"I knew the day had to get better at some point." he grinned as he stepped forward on the elevator, so that he was even with her as the doors closed.

Meredith's head quickly turned towards him, worry overtaking her expression. "What happened?"

"Well, I had a visitor in my office when I got to work this morning." Mark scratched his beard softly, trying to find the words to say it nicely.

"A visitor?" Meredith raised her eyebrows, thinking it was probably some girlfriend he left in New York.

"Yeah." Mark sighed, deciding not tell her. "Anyway, how's the hangover?" He grinned, trying his best to change the subject. The elevator doors opened before Meredith could respond, only for Addison and Derek to be standing there. All four froze slightly, each unsure of what to say.

"I.. I'll take the stairs." Derek mumbled before turning around and walking quickly away.

Once Derek was gone, Addison shook the odd feeling off and turned to Mark. "Mrs. Williams is waiting for you in 302."

"Thanks Addison." Mark nodded before making his way off the elevator, Meredith following behind.

"That wasn't awkward at all." Addison mumbled as she stepped onto the empty elevator to go find Karev, apparently Bailey enjoyed torturing the guy almost as much as he did.

"Karev!" She called out his name from the exit of the elevator just as she was entering the stairwell. She couldn't hide the grin on her face as she watched him grimace before turning around and making his way to her.

"Why do you hate me so much?" He mumbled as he made his way onto the elevator that she'd held the door open for him.

"Wasn't me today. Sorry." She half smiled at him before returning to her professional demeanor. "So today isn't going to be hard as far as I can tell."

"Of course not. It's gynie squad." Alex muttered under his breath before plastering a grin on his face and nodding at her. "Great."

"Come on Karev. Do you really want to work with Sloane and fetch his coffee?" She asked only half seriously, but was happy none the less when a defeated look overtook the intern's face. "Exactly." She smiled as the door opened on the floor they needed to get off on.

"You know, you aren't as bitchy as people make you out to be." He spoke up once they reached an empty nurse's station, causing her to look up from the chart she was glancing over.

"Never underestimate the Ruler of all that is evil!" She grinned as she watched his eyes dance in amusement.

"You rule me now? I'm the Evil Spawn." He couldn't help it. Even if he did hate her 99 percent of the time, there was still that one percent that completely enthralled him. She was addicting.

Addison knew she should chastise him for the inappropriate reference, but it'd been so long she'd heard that tone in someone's voice that it was nearly impossible to. So, instead her cheeks flushed momentarily before she looked away. "Let's go check on the patient, shall we?"

"Whatever you say, Master." Alex grinned as he followed her down the hall.

Please Review!

I know the Addex scene was kinda short. It was just kinda an intro to them. Much more to come!
