I know. I know. I said two or three weeks, but things happened and you know. That's how it goes with two small children. This is set in the "Turn and Turn Again" universe, but it happens about a year before that story, so obviously you don't need to read that story first. All you need to know is that Derek never went back to Addison and he and Meredith have two boys, Christopher and Jacob. If you haven't read one of my stories before, there are some things you should know:

I try to update weekly to the best of my ability

Any questions should be asked in the reviews and I will try to answer if I can

Feel free to share ideas with me, if I use them I will give a shout out in an AN

First part is a "missing scene" from the actual storyline. Basically it's the exact moment when Derek decides he still wants to be friends with Mark.

Mark knocked gently on the door of the trailer. He wasn't sure what else he could say to try to change Derek's mind, but he knew he had to try. Derek was his best friend, his brother, and he wasn't willing to give up on that part of his life. He heard the sound of shuffling from within and suddenly he was face to face with Derek.

"You have a lot of nerve," Derek growled.

"I just need to explain…or something…I can't lose you," Mark sighed, suddenly feeling unsure of himself.

"You don't deserve a chance to explain. Just…forget you ever knew me," Derek spit.

"I can't not be your friend," Mark said, "I know it doesn't count for much but I was hurting."

"That doesn't give you a reason to betray me," Derek sighed, knowing exactly what Mark was referring to.

"I know…well I do now…but at the time I just wanted someone to need me. It wasn't about Addison…or you," Mark tried desperately to explain.

"Damn it Mark. It doesn't matter. The sooner you can get that through your head the sooner we can forget each other ever existed," Derek said, but his voice was losing the fire it had previously held.

The slight change in voice didn't go unnoticed by Mark and he decided he might be able to wear him down.

"Does it even matter anymore? You met Meredith. You left Addison, but you can't forget about me anymore than I can ignore you. I'm not going away. Please, what is it going to take for you to forgive me...I've lost enough," Mark cried, his voice thick with emotion.

Derek sighed and his hand reached up to grasp Mark's shoulder. Mark glanced up, his eyes locking with Derek's as he was steered toward a couple of chairs on the porch. He knew their relationship was by no means repaired but he hoped in time it would be.

Four years later…

"You are so not going to believe this," Derek said as he settled into the spot next to Mark on the catwalk, "this guy comes into the ER, massive hematoma, so I ask what happened. He says he fell, but I can clearly see some kind of excessive blunt force trauma. It didn't look like an accident. Long story short, ask me what his wife hit him with."

Mark stayed silent. His eyes locked on something below them.

"Hello? Earth to Mark. What are you even looking at?" Derek tired again, following his gaze to a figure below.

"Is that…?" Derek started.
"I'm not sure," Mark sighed after realizing Derek had spotted what he had.

"Why would she be here?" Derek asked.

"I don't know?" he replied.

"Are you going to…?" Derek tried.

"I don't know," Mark said harshly before turning away abruptly and walking away.

He spent the rest of the day floating from surgery to surgery. When it was finally time to pick up Kennedy and head home he sighed in relief. His mind was drifting as he made his way to the hospital daycare to pick her up. He gave a quick hug to Christopher then found Kennedy standing up in a crib in the baby room. Picking her up, he gathered her stuff quickly before heading toward the elevator, hoping to make a quick getaway. He waited impatiently for the doors to open. Kennedy babbled in his ear and he smiled, temporarily forgetting about the thing that had weighed on his mind all day. A ding signaled that the cart had arrived at the floor, and his attention moved back to the doors. When they finally whooshed open, Mark gasped. If any doubt had been left in his mind about the identity of the person he had seen earlier, it disappeared. She looked exactly the same as he remembered. A little older of course and her dark hair was short now, but he would remember those eyes anywhere. They had haunted him for years. Pale blue-grey eyes that somehow managed to be warm and inviting even as the woman they belonged to was breaking his heart. He immediately turned to run in the other direction, but she stepped quickly forward and grasped his wrist to stop him.

"Don't," she said.

He stood still but didn't turn around.

"We can't run away every time we see each other. I didn't know you were here. Richard called, said he had a position available. He wanted me to come out here, get a feel for the place, but…I just wanted a change of scenery, I didn't know…" she trailed off.

Mark turned roughly, jerking his wrist from her hand roughly.

"Why the hell would you. You stopped having the right to know anything about me when you sent those papers in the mail," Mark spit.

"That's not fair. That relationship had ended a long time before that," she spit back.

Mark's hand moved up instinctively to clutch Kennedy to him, protecting her from the harsh words.

"And that was for you to decide? I guess I wasn't in the same relationship that you were" he practically screamed.

"Don't put this all on me. I didn't cheat on myself," she yelled back.

Mark looked dumbfounded.

"I never…not even once…" he said softly.

Derek suddenly emerged from the crowd of people that had gathered and positioned himself between them.

"Mark, go home." He ordered before addressing the woman, " hello Emily."

"Derek. I heard about you and Addison, it's a pity," she replied.

"Not really. How long are you going to be here," he asked coolly his eyes following Mark's retreating back.

"Richard offered me a job, but I'm only here for a two week trial right now. After that, I'm not sure," she answered.

"Do me a favor. Stay away from him," he said before turning and walking away.

So fairly short chapter, but I was just trying to get the story started. I will say it time and time again, please review because they are an important part of the creative process and I love to read them.
