Short chapter… I know. Anyway, I've been pretty absent because I've been very into my music career right now, I'm on spotify! Anyway, hopefully you enjoy this really short chapter. Will try to post soon.

Derek walked inside that hospital and tried his best not to look like an angry smurf, and considering he had to wear the same clothes as yesterday he knew people were going to talk about that. Probably make a big deal out of it, nurses would have that look on their eyes like their lives finally have a meaning because they know something that other people don't. The usual chattering and glances getting on his nerves in an aggressive way, and the lack of sleep wasn't amazing either.

He wanted to go find his wife, get things right. Ask for forgiveness if he had to, even if he was too proud and stubborn to admit that maybe she was right about what he liked to call the 'Mark Matter'.

He wasn't in the mood to speak to anyone, he didn't even want to have to face his patients today, considering he had a crappy sleep and a crappy night as well. All he wanted was to speak to his wife, figure out how to fix this whole… Mark Matter.

But just when he went to look for her, he ran into the main character of 'Mark Matter'. Mark Sloan himself. Derek rolled his eyes at him and kept walking, him following suit, of course.

God, how he wished the day could end now.

"What do you want." Derek said, Mark walking at the same pace as him, next to him, staring at him, annoying him.

He chuckled, "Look, I just want to make things right." Mark said, sounding smug.

Derek stopped on his tracks, "Oh, I'm aware."

"Come on, Derek. We've been best friends since kindergarten." Mark said, letting his hands slip into the pockets of his lab coat.

"You had sex with my wife and sister!" Derek said, anger registered on his features, voice and eyes.

For Derek's surprise, his former best friend's eyes widened, "Crap, you found out about that too?"

"Addison, my wife told me." Derek said, starting to walk again, hoping he would stop talking and following him.

"In Liz' defense, she had just broken up with-"

Derek turned around aggressively, Mark almost bumping against him, "Liz?! You fucked Liz too?!"

"What sister were you talking about?" Mark said, in a serious way, for Derek's disgust.

"Nancy!" Derek said, raising his voice.

"Ahh… Nancy." Mark nodded and smirked with that one mischievous smirk of his.

Derek scoffed, "You are unbelievable."

"If you're looking for Addison, she's not here. I already performed my own search party." Mark said smugly.

"You know what?! He 's an asshole! That's what he is. And that asshole impregnated me for God's sake."

"Wait, we're talking about Mark or Derek?"

"Mark. Well, both. Both qualify to the definition of 'asshole'."

"But you love your asshole, right?"

Addison giggled, "Jesus Callie, this is turning into a really weird conversation."

"I meant Derek." Callie replied with a laugh.

Addison nodded, her cheeks turning a little pink, the thought of her husband made her heart feel warm, and she couldn't deny that being mad at him wasn't easy, "Of course I love him. But I love Mark too. I mean, not like I love Derek. I did fall for him… or the idea of having someone there for me. I don't know. I just know that I did love him, but Derek's the one that owns my heart. He could break it a hundred times and I'd still love him, even if he's the most stupid human being at times." The redheaded woman said, tucking a strand of hair behind her ear.

"But you're mad at him." Callie pointed out, sitting down on the edge of Addison's bed, putting some lotion on her dry hands.

"I am." She nodded, sighing heavily and then she ate another grape, lying back against the soft pillows of the hotel room bed.

"Anyway, I'm going to the sauna." Callie said, standing up, "See you here in about an hour?"

"I'm not going anywhere." Addison chuckled and rested her hands against her belly, which was covered by a fluffy hotel robe. She hadn't been back to the Archfield for a while now, but the hotel she had went with Derek that one time had fluffier robes, that's for sure.

Callie exited the two bed dorm they had both rented for the day and the night as well, their chec-out being next day at ten AM. Addison had been very upset because of the fight and needed a little while to relax and think. Maybe she was the one overreacting, maybe Derek was being rational and her hormones were blinding her from that; either way she needed to take a moment for herself and Callie was going to be her company.

Everything started to turn silent, and peaceful. But her phone buzzed. It was the first time she had heard it buzz today, she had left it inside the room while they were at the SPA and during their massages. She grabbed her blackberry and found she had seven missed calls, five from Derek and two from Mark, Oh! And a text from Richard, "Your husband is asking for you".

She sighed and dialed the familiar number, hating herself because she knew she was going to get rude at him and be all 'leave me alone, I'm not a damaged puppy'.

He was in the middle of a surgery and had told his intern that whatever happened, if it was his wife to please stop whatever he was doing inside that man's brain and give him the phone. Well, not exactly using those words, he just wanted to be told if his wife was calling him or not.

Meredith herself was on his service today. He would have been thrilled to have her on his service some months ago, but now he's not so thrilled, because the looks she kept giving him were making him incredibly uncomfortable. A phone buzzed and Grey looked down to her pocket, where she was keeping Derek's phone, but she nodded her head no, "It was mine."

But It wasn't hers.

That damn voice… "leave a message after the beep," she hated it. It was sort of a funny thing because she had her own personalized message for voice mails, but Derek had refused to have his own, he thought it was such a cliche; even though he couldn't deny he loved Addison's.

"Derek, it 's me. Um, well you called and I suppose you're busy or… whatever. Anyway call me. I think I'm ready to talk." She said, letting a harsh sigh out of her mouth. Addison turned to her side slowly and was about to leave her blackberry back on the nightstand, but just when she was about to, the phone buzzed.

Mark Sloan

She scoffed, not believing it at first and then answered the call, "Addison Shepherd," She had no idea why she had responded with her professional name, but did it anyway.

"Mark Sloan on the phone, do you have a minute?" He said, his sarcasm evident as he answered with his own profesional name.

"Sadly I do." Addison sighed, running a hand up and down her slightly swollen abdomen.

"Even for me?"

"I swear I'll block your phone number if you keep annoying me." She said, using a defensory voice.

"Woah, woah. Relax mama bear."

"Mark, I'm not in the mood. What do you want?" She snapped.

"Where are you?" He replied, surprisingly sounding less cocky than usual.

"Took the day off."

"That's not exactly a location."

"I'm fine," She said, adding some emphasis to each word, making pretty clear that he was a pain in the ass, "trying to relax but you're not helping. Why do you need to know my specific location anyway."

"Your boyfriend has been whining about your absence the whole morning."

Her cheeks blushed, "Tell Derek I'm fine. And please don't push him, it's hard for him too. Just don't get on his nerves." Addison requested nicely, her tone neutral as it had been the whole call.

"Okay, but I was talking about Karev." He chuckled.

Addison rolled her eyes, "Goodbye Mark."

"Good indeed!"

She ended the call before it could get worse than it was already.
