Disclaimer: I don't own Grey's Anatomy, that honour goes to the wonderfully talented Shonda Rhimes. Nor do I claim any ownership to the song 'Speechless,' sung by the awesome Veronicas. In my dreams, however, McDreamy and even McSteamy are all mine!

A/N: OK, so I decided to turn this oneshot into a full fic, so here goes: As I haven't seen any episodes with either one of them yet, Callie and Denny don't exist for the purposes of my story. George and Meredith never slept together, Alex and Izzie are back together, oh, and Burke never got shot too. The reason I've changed this so much is because I haven't seen the episodes with these events in them, and I wouldn't want to write something that doesn't fit in with what has happened, but still continue with what has happened, if that makes ANY sense at all to you wonderful readers. BTW, Italics are thoughts and bold italics are songs. So, R&R, and enjoy, of course! P.S. please excuse any bad medical speak – I'm a law student, not a med one!

Previously on "In Each Other's Arms…"

Arriving at Addison's Office, Mark could see her sitting at her desk, her head resting in her hands. She looked up and saw him, blinking a few times to test her vision. He walked in the door as she stood up, and waited for her to come to him. She walked over to him, hardly believing her eyes. Sweeping her up in a huge embrace, he acted on instinct. When he started to kiss her, she didn't push him away. Leaning past him, she closed the door while they kissed, stealing them away from the prying eyes of Bailey's interns and the rest of the hospital.

………

"Well," Meredith began, "Derek and I have been taking it slow since we got back together. We never took it slow the first time – we were supposed to have a one night stand for crying out loud! Talk about your one night stands coming back to bite you on the ass!"

"No, I think the one night stand that came back to bite you on the ass was the guy whose penis you broke – remember him! God, and then you had to tell Shepherd about the two of you. Classic!" At the look on Meredith's face, Alex decided that it was time for him to leave. He hadn't counted on Meredith chasing him down the hallway, attempting to catch him to hit him, and they ran away from the others watching them with bemused looks on their faces.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

"Wait, Mark stop for a second. We should talk before we do anything." Stopping was the last thing that Addison wanted to do – she had been dreaming of this moment since Mark's last visit to Seattle, despite the fact that she had still been 'trying' with Derek at the time. Perhaps that was why she was so easily able to forgive him and Meredith for loving each other the way they did. Truth be told, she'd never stopped loving Mark, and she and Derek had just been living a lie – she'd just been too scared to end it, she wanted to stick with the safe option. Well that worked out well, she thought.

Mark took no notice of her words, kissing the nape of her neck while guiding her to the couch she'd recently added to her office.

"I've gotta say Addie," Mark came up for air, "I'm damn glad that there's a couch in this office, coz that makes my job so much easier." Flashing her one of his trademark cheeky grins, Mark resumed kissing Addison, working his way down her body, removing her clothes as he went with his teeth.

"Mark, if you keep doing that," Addie gasped, "I'm not gonna be able to resist you – OOOOOOOOhhhhh" She groaned as he reached her most sensitive spot.

"That's the general idea Addie. You know you want this as much as I do. There'll be plenty of time to talk later."

He's right, she thought. Screw talking, this is soooooo much more fun. Finally, I'm back to the really good sex. It's about time.

Feels like I have always known you
And I swear I dreamt about you
All those endless nights I was alone
It's like I've spent forever searching
Now I know that it was worth it
With you it feels like I am finally home

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

"Hey Derek, have seen Alex?" While trying to find the Evil Spawn, Meredith had inadvertently run into Derek – literally. He'd grabbed her wrists to steady her, but now he wasn't letting go – still holding her close. Ok, this could be a problem, how am I supposed to take it slow and resist him if he keeps holding me this close?

"Forget Alex, come with me," Derek tried to convince her. "We'll make our own fun…"

"Yeah, that's what I'm afraid of." A visibly flustered Meredith wrenched herself from Derek's grip, and when he smiled that knowing, McDreamy grin down at her, she knew that he'd seen that he'd gotten to her. Dammit, I'm like a lovesick, horny puppy around him. Gotta work on my poker face!

Falling head over heels
Thought I knew how it feels
But with you it's like the first day of my life

"Look Derek, I've gotta find Alex so I can kick his ass for teasing me, can you help me with that or not?" Meredith's attempts to put some distance between her and Derek wasn't working – the more she backed away, the more he followed her. It was like a vicious cycle she couldn't escape.

"Karev is with a patient at the moment – Burke called him about two seconds before you bumped into me. So, why don't you come with me," he said, taking hold of her elbow and guiding her into the elevator. "I have a patient having Grand Mal Seizures that I could use a hand on. I believe you have some experience in that field – remember Katie Bryce?"

"O-okay," Meredith stuttered, suddenly very aware of the fact that they were alone in the elevator and the doors were rapidly closing, with no chance of anyone saving her from being alone with Derek. Great. Just Perfect. We both know how bad my track record is with elevators and Derek. At this rate, I'll never be able to keep myself from jumping him!

"Okay, Dr. Shepherd, tell me about this patient of yours."

"Dr Shepherd? What's up with that?"

"Just trying to keep it professional. So, your patient, Dr Shepherd?"

"Well, Dr. Grey," he emphasised, "she's a-" Suddenly he stopped talking as the elevator lurched to a halt. They grabbed each other to steady themselves as the lights flickered and dimmed.

"Oh no, this can't be happening, I cannot be stuck in an elevator with you, this CANNOT be happening." Meredith hadn't realised that she was speaking out aloud until she heard Derek's reply

"Dr Grey, you wound me. Am I that repulsive to you?"

Meredith took a good, long look at him. Damn him and his stupid McDreamy look. Why does he have to take my breath away? Jackass! Throwing caution to the wind, she dropped the files she was holding, pressing him against the elevator wall to kiss him. God, I'm getting the weirdest sense of de ja vu! Screw taking things slow, I give up, I surrender, she thought, as she began to take off his scrubs.

Cuz you leave me speechless
When you talk to me
You leave me breathless
The way you look at me
You manage to disarm me
My soul is shining through
Can't help but surrender
My everything to you

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

"I…er…wow, that was just so…wow, I can't believe that we finally…wow, huh!"

"Good to see we've still got it, huh Addie?"

"Wow!"

"I believe you've already said that a few times."

"Were we always that good together? Because, speaking as woman who's had really crappy sex – well most of the time – since she left Manhattan, we've got a good thing going on here!"

"Yes, we do." Mark agreed, looking pensive as he lay on the couch with the woman he loved in his arms.

"Mark, what is it?" Addison had sat up, and, noticing the look on his face, decided to stop putting off the talk they so badly needed to have. "What's wrong? Did I do something wrong?"

"God Addie, of course not. You could never do anything wrong – well, except not telling me about your divorce for two months, but I'm over that. I think the unbelievable sex proved that!"

"Well, what is it then? Is it the girl that answered your phone and was in your apartment when I came to New York? Is she your girlfriend? Did you move on? Coz, I wouldn't blame you if you did, I mean, I was with Derek even though his heart was with Meredith and-"

"Addie stop, you're rambling. I thought that was Meredith's thing – excessive rambling."

"I guess I've been spending too much time with her," Addison laughed.

"How is it that you're still able to be friends with her after what her and Derek did to you? How can you be friends with either of them, for that matter?"

"So, dodging my question are you?"

"No, I'm not dodging, but if you answer mine, I'll answer yours. Okay?"

"Seems like a fair trade." She mused. "I'm assuming you already know what happened on Prom Night?"

"Yeah, Derek filled me in when we were at Joe's earlier on tonight, after our fight when you were with Meredith."

"Well, after that, it was a bit tense between all of us for a little while. Derek and I filed for divorce, and Meredith walked around with a guilty look on her face all the time, avoiding me like the plague. Then, one day, I requested her to be my intern, relieving Karev from the 'vagina squad' as he called it. I wanted to put an end to it, I wanted her to know that I didn't blame her for what happened between me and Derek. It's not their fault that they fell in love, you can't help that anymore than you can help being struck by lightening. I can't condone the fact that they had sex, coz Derek was basically cheating on me then, nor do I like the fact that he begged her to take him back before he had even told me what had happened, but the way I look at it, that was karma coming back to bite me on the ass for what we did. Meredith and I had a really long talk, and we got everything out in the open. She told me that I could do my worst, say whatever I wanted, and she wouldn't hold it against me because she deserved it. I think I shocked her with my stance, and my karma belief, but there you have it. It's taken a while to get over the uncomfortable stage, despite my reassurances, but we're pretty good friends now. In fact, they've invited me around for dinner at Meredith's place tomorrow night. Should be interesting." Not one to be deterred, Addison refused to let Mark off the hook. "So, time for the answer to my question now – who's the girl?"

"Well, it was my sister. I know that that sounds unbelievably clichéd and all, but it's true – Derek can vouch for me on this one, as odd as that may sound. She'd come to look after me for a while, coz I wasn't doing such a great job of it myself. As impossible as it may be to believe that this could happen to someone as confident and fantastic as me, I was kinda depressed and withdrawn, not going to work and pretty much just throwing my life down the crapper. But she helped me get back on my feet, and encouraged me to take Richard's job offer despite the complications that may arise. She taught me to fight for what I want, and to just go for it."

"I'm sorry, did you say 'Richard's job offer?'" Addison was in disbelief. "Richard, as in Richard Webber, Chief of Surgery here at Seattle Grace, that Richard?"

"The one and the same."

"Well, what job did he offer you? Is it a temporary one, or something more permanent?"

"I'd say something a little more permanent – you're looking at Seattle Grace's head of the newly expanded Plastics unit. What do you think?"

"What do I think? OMG I think that's fantastic! That's great, you'll be here all the time, we can finally be together!" Realising she was getting ahead of herself, and feeling insecure all of a sudden, Addison made to correct herself. "I mean, if you want to that is…"

"Well, I didn't take this job to be closer to Derek, Addie – although we seem to be getting along now, it's crazy! I took it so that I could be near you, even if I couldn't be with you. I guess it's kinda like a fantastic bonus now that you're divorced.

As he leaned in to kiss her, Addison realised how much he truly loved her. He was willing to be here even though he thought he couldn't be with me. He was willing to watch me go through the motions with Derek if it made me truly happy, even though it would've made him miserable. As she kissed him back with a fervour, she realised that she couldn't resist him. He made her so happy, he made her feel alive again.

I thought I could resist you
I thought that I was strong
Somehow you were different from what I've known
I didn't see you coming
You took me by surprise and
You stole my heart before I could say no

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

"Well Dr. Shepherd, so much for taking things slow," Meredith remarked as they were getting dressed. They had been stuck in the elevator for over half an hour, and had well and truly put an end to their self-avowed celibacy.

"I thought it was fun. It was about time we did it; it was amazing that we lasted two months together without sex!" He moved closer to Meredith, caressing her face as he leaned down to kiss her. "By the way," he said as he paused, "stop calling me Dr. Shepherd, it turns me on," he whispered in her ear, firmly planting his lips on hers as she gave an involuntary shudder. "You know what, forget I said that, I like it when you turn me on!"

Falling head over heels
Thought I knew how it feels
But with you it's like the first day of my life

Oh God, here we go again, Meredith thought. I am so weak, but I love being with him so much. OMG, what was that?

Breaking away from Derek, Meredith realised that they were moving again. As the doors opened, she made to fix her rumpled scrubs and her mussed hair, urging Derek in her head to do the same. This must look so bad, she thought as she walked out of the elevator.

"We'll talk about this later Dr. Grey. Don't think you can escape me that easily." With that, Derek went in the opposite direction to Meredith, giving her a chance to collect her thoughts.

"So, I guess the whole 'taking it slow' thing is over, huh?" Queried Christina as she caught up with Meredith. "How long were the two of you in there anyway?"

"Long enough. Too long."

"What are you so afraid of? Why are you so afraid of being with him properly again?"

"I'm not, I'm fine."

"Meredith, you say 'fine' that much that it doesn't even sound like a word anymore. What's the matter with you?" Christina could sense Meredith's reluctance to talk, but she pressed on anyway. It's what she would do to me!

"I guess I'm just scared that if we take it as fast as we did last time, something else is just gonna come and bite me on the ass and ruin my happiness. Like another long-lost wife or girlfriend or kid. I know that's not possible coz he was upfront with me this time, but I guess I'm still scared."

"Have you told him that?"

"What, that I love him so much, but I afraid of being hurt again? Not really."

As they walked away, Christina put her arm around Meredith. Meredith was touched by the gesture, knowing that Christina is not a touchy-feely type.

"Don't forget Mer, I'm your person if you need me, but I still think you should talk to Shepherd."

"I will. Soon." Once I figure out how to talk to him without screwing him first!

You leave me speechless
When you talk to me
You leave me breathless
The way you look at me
You manage to disarm me
My soul is shining through
I can't help but surrender
Oh no
My everything to you

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

"Meredith, Meredith wait up!" Hearing a familiar voice shout out her name, Meredith stopped and turned around to see who wanted to talk to her so urgently when she was leaving the hospital. Her shift had finally ended after a harrowing forty-eight hours.

"Addison, what's wrong? Do you need an intern?" Her heart sank as she asked this question, praying to God that she could just go home and sleep.

"No nothing like that, I just wanted to thank you for the advice you gave me on how to handle the Mark situation." Meredith's heart soared at this, glad she didn't have to stay much longer.

"I'm glad you two worked things out," Meredith replied, opting out of feigning ignorance on the situation as it stood. Too much had come between them for that. "I heard that you two had a moment in your office."

"And I heard that you and Derek had a 'moment' in the elevator today when it broke down!" Addison laughed.

"Oh, you heard about that?" Meredith was crimson. "And it didn't freak you out or anything?"

"No, it didn't. I guess I truly am over Derek," Addison mused. "It just wasn't meant to be. The two of you on the other hand…"

"A bit like you and Mark."

"I don't know about that either. Don't get me wrong, I really hope so, in fact I'm sure that it's probably the case, but we've never had a real relationship. We stayed together for a few weeks before I came out here, which Derek knows about by the way, but I was still married then. Now, we're both free to be together. It's kinda surreal."

"Yeah, I know exactly what you mean. That's pretty much how I feel with Derek." About to walk away, Meredith thought for a moment, before turning back to Addison.

"Addie, are you still coming to dinner tomorrow night?" she questioned.

"If I'm still invited," Addison laughed.

"Of course you are, I was just going to say that you should bring Mark. He's a part of your life now, and he's not going anywhere. This way, he can meet everyone else, get up to speed with everything, you know, make a few friends, yada yada yada."

"I would love that. Count us in. Thanks Meredith, I really appreciate this."

"Addison, it's the least I can do. You've been so kind to me since everything happened, and I just want to repay the favour. I know that I don't deserve you're kindness, but I'm truly grateful for it."

"Meredith, it's nothing. So long as Derek is okay with it…"

"Derek won't be a problem, I'll make sure of that!" Meredith chuckled."

"I'll let you be on your way then. See you tomorrow night Meredith."

"Bye Addison."

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

"Derek, man wait a second!" Derek turned around as he was walking out of the hospital to see Mark running towards him. "You leaving already?"

"It's the end of my shift, I'm about to meet Meredith outside so we can go to her place. I'm so tired, all I want to do is sleep."

"Well, sex in an elevator will do that to you," Mark cheekily remarked.

"So can sex in an office," Derek retorted back. "Did you call me back for a reason Mark?"

"Yeah I did. I just wanted to thank you for your advice concerning Addison, we've talked and gotten through most of our issues. That's thanks to you man, coz I don't know how receptive I would've been to talking with her before you came and advised me. You always did know how to convince me into doing things."

"Hey, I didn't convince you into doing anything, I just offered some advice to guide you a little."

"Well it meant a lot to me, considering the fact that you don't owe me any favours."

"Yeah, well…" Derek looked uncomfortable. "Anyway," he said, brushing the issue aside, preferring not to think about it. "I assume Addison's told you about dinner at Meredith's tomorrow night?"

"Yeah, she mentioned that she was invited."

"You should come too, you're a part of Addison's life now so you'd be more than welcome."

"I'd like that Derek, if it's okay with Meredith. I wouldn't want to be intruding or anything."

"Nonsense, it'll be fine. Plus you'll get to meet everyone else – Bailey and her husband, Burke, Christina, Izzie, Alex, George, and whoever George brings. We can get you up to speed on all the sordid hospital gossip."

"You mean there's sordid hospital gossip that doesn't revolve around you and Meredith? I'm shocked Shep!" Mark mocked.

"Watch it Mark, I can still flatten you like I did a few months ago."

"Well, I'm not in the mood to suture my own face again, so I'm gonna go now. Enjoy your night, and I'll see you tomorrow night."

"Bye Mark." Both men turned to go their separate ways, marvelling at how easily their former repertoire was returning to them.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Sitting in the car on the way home, Meredith was trying to come up with the best way of telling Derek that she'd invited Mark to join them at dinner the next night. What she wasn't expecting was for Derek to beat her to it.

"So Meredith, I hope you don't mind, but I've invited Mark to join us tomorrow night. You know, as Addison's guest. It doesn't seem fair to make her come on her own, and this way he can meet everyone else properly too."

"Wow, you took the words right out of my mouth. I invited him too, through Addison. Pretty much for the exact same reasons. Huh, and here I was thinking that I was going to have to use all my feminine wiles to convince you to let him come. Oh well…"

"You know, you don't need an excuse to pick up where we left off in the elevator. We could stop the car now if you want!" Derek countered cheekily.

"Let's just wait til we get home," Meredith laughed, thinking to herself how much Derek had surprised her lately with his extension of friendship to Mark.

You leave me speechless
(the way you smile, the way you touch my face)
You leave me breathless
(it's something that you do I can't explain)
I run a million miles just to hear you say my name
Baby

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Addison sat in her office, going over her post-op notes and planning her surgeries for the coming days. It's been such a long day, she thought. But definitely a good one despite its poor beginnings! I wonder what Mark's up to?

"Hey you." The object of her thoughts was standing in her doorway, looking lovingly into her eyes. "You ready to go yet?"

"Yeah, I can finish this tomorrow. Where are you staying Mark?"

"Well, I was hoping that I could spend tonight with you, you know, really celebrate our reunion," he insinuated. "Oh, by the way, something rather strange happened tonight. Derek invited me to dinner with you tomorrow night at Meredith's. How funny is that?"

"Huh, that is strange. I guess he didn't know that Meredith told me to bring you. Which is good, coz it means that they're both okay with it, and there won't be any hassles to spoil the dinner. And you'll get to meet everybody, learn all sordid histories, etc!"

"My god, that's what Shep said. How much sordid history can this place hold!" Mark was incredulous, having not taken Derek seriously before.

"You'd be surprised Mark," Addison replied while shrugging on her coat. "So, we're picking up where we left off at my place? Sounds like fun to me!" He wrapped his arm around her as they walked out of her office together, both amazed at how everything had come together, and for the better.

You leave me speechless
You leave me breathless
The way you look at me
You manage to disarm me
My soul is shining through
I can't help but surrender
My everything to you


A/N – So, I think I'll leave it there. It's rather long, but it just flowed. I hope this pleases those reviewers asking for longer chapters! I hope that you liked this, and that I'm doing a good job. Please let me know, otherwise I'll go insane! I'm serious, just hit the little blue button in the corner and submit a review. I hope that the characters seem realistic. This one was rather Meredith/Derek/Addison/Mark heavy, but there will be others in the next chapter. I'm also thinking of introducing Callie for George in the next chapter too. PLEASE REVIEW! 
