A/N: First of all, thanks so much to all who are still sticking with me and reading this story. Here is chapter 28 for you :) Second, you should know that in this story, Mark and Addison DID have a one night stand, but it was only the one time. They never stayed together afterwards like they did in the show. I figure you probably already know that based on my earlier chapters, but still. Just wanted to make sure. Enjoy!

Disclaimer: I don't own anything.


Chapter 28

Addison's POV

"Punching out people on my surgical floor? My head of neurosurgery punching out people on my surgical floor?"

Richard paces around the conference room, not bothering to hide his angry glare. I think out of all the bad moments for Mark to show up in my life, this one takes the cake. And honestly, I have no idea what he's doing here; Derek is angry because for some reason, he thinks I'm insane enough to call the man I made the horrible mistake of sleeping with.

Just perfect.

"Put the ice back on your hand," I mutter to Derek, who so graciously removed the ice pack I gave him for his hand just as soon as I put it on.

"My hand is fine," he glares at me.

"Put the damn ice on your two million dollar a year hand!" Richard yells. "Now, would someone tell me what the hell happened?"

Oh thank God, he doesn't know about my side of the adultery yet. That makes me feel so much better.

"That was Mark," I look down at my hands.

"Who's Mark?"

"He and Derek used to work together back in New York," I start, suddenly feeling very queasy. "And um, they were – we were all close friends. Until Derek found us in bed together…"

Apparently this is all Richard needs to hear for us to come to an understanding. Except there's still one thing I don't understand: what the hell is Mark even doing here? And why did he have to show up now, when Derek, Laurie, and I are finally getting back on track as a family, and I'm having another baby.

Oh yeah, the baby. Laurie. The argument. Really, could this day get any worse? Oh yeah, it can, because Richard still doesn't know about the baby and now would probably be the worst time possible to tell him.

"You put your weight behind it?" Richard turns to Derek.

"Yes, sir," he nods.

"Well alright then." Quickly, Richard turns and walks out the door, leaving Derek and me alone.

"What the hell is he doing here?" Derek asks me.

Funny, I've been wondering the same thing this whole damn time.

"I have no idea," I sigh, but the way my husband is looking at me tells me he doesn't believe me. I lean forward, my head in my hands, and still feeling very queasy.

We sit together for a moment in silence, the tension cutting through us like knives. But neither of us really knows what to say; it's not a good time to talk about anything. Suddenly, Derek stands up, tossing the ice pack back on the table and storming out, hopefully not to go beat up our former best friend.

Trying not to cry when I know people can see in the windows, I place a hand lightly on my still-flat stomach. The truth is, no matter how angry Derek is with me right now, I am having his baby…again. I already have one, no two, of his babies. No matter what he says or does now, we will always be connected. Back when Laurie and I were in New York had no idea where he was, I doubted that, because it seemed like even though I had his kid, he got rid of all contact anyway.

But now that he's seen her and realized how wrong he was for leaving her, he'll never leave his children again. I'm sure of it.

Despite everything – Mark, Derek, and my earlier fight with Laurie – I look down at my hand and can't help but smile. I have my first ultrasound appointment tomorrow, and while this baby was very, very unplanned, I can't help but feel excited about this little life growing inside me.

After Rinny died, for the longest time I was terrified at the thought of having another baby; I couldn't just replace her and pretend like I never had a second child. I couldn't risk having another baby who looked exactly like the one I lost. I'll admit I'm still nervous about it, about how I will feel when I see him or her in actual human form on the ultrasound in a few months - will I think of Rinny? Will it be too much to bear? – but right now, at this very moment, I can feel very much okay with this little one.

Making sure I'm alone enough, I rub my hand back and forth.

"Hello, little one," I whisper. "It's Mommy. I'm sorry things are so stressful right now, but I want you to know that none of it is your fault. Your big sister…she doesn't, she doesn't hate you, she hates me. I haven't exactly been the greatest of mothers lately, and I think it's just now hitting her. But Laurie, she's the best sister any kid could ask for. I know she'll love you no matter what."

By this point I'm facing away from the window, my eyes brimming with tears.

"Your daddy loves you too, he's just upset right now about Mark, but you don't need to know about that. He's such a good daddy; he'll teach you to play soccer and then make me mad for tracking mud into the house," I laugh. "Your sister used to do that all the time."

"You should know too that you have another sister, Rinny," I swallow, her name tasting like pennies in my mouth. "She…she was killed, ten years ago, and she's in heaven now. But she'll look out for you, my little angel."

"Honey, all I want for you is to be happy and healthy, and know that you're loved. I…I've messed up a lot of times in my life baby, but I want you to know…making you was not a mistake, and I'll always love you."

Leaning back in my chair, I let out a long sigh. The queasiness passed, luckily without me having to go hug the toilet this time. I realize that it's almost two – time for Laurie's appointment. After she showed up in my office with the discovered pregnancy test, and then we both ran into Mark after our fight, I came in here with Derek almost right away. I have no idea where my daughter ran off to.

Her finding the pregnancy test in the trash can was definitely not the way I wanted her to find out. But I had been in a hurry, and the trash can was just there, and I didn't think. Of course she would see it lying on top of the garbage; this was just another one of my stupid mistakes that I now need to fix.

Sitting up slowly, I compose myself before walking out of the conference room, in search of my daughter.


"Dr. Montgomery Shepherd!" I hear Dr. O'Malley call my name from behind me in the hallway.

Sighing, I turn around.

"What is it, Dr. O'Malley?"

"It's just um, we have a patient down in the ER. Minimal injuries, but she was in a car accident."

Forgetting everything that just happened with Mark, I spring into action. All I hear are the words "car accident" and images of my two children spring into my head.

"Well what are we waiting for, O'Malley, why didn't you page me sooner?" I turn on my heel and walk away quickly, before George can get another word in.

"Wait, Dr. Shepherd!" He calls, before running after me. But I can't stop because this situation feels all too familiar to me.


"Spontaneous orgasms?" I ask, giving Izzie and George a curious look while standing in the ER doorway. "Are you sure?"

As it turns out, this situation is not quite as familiar as I thought.

"Oh yes."

"Kind of hard to miss."

Izzie and George answer at the same time.

The patient, Pamela Calvin, really doesn't look too much older than my own daughter, which doesn't make this appointment any less awkward, for all parties involved.

"Miss Calvin, I'm Dr. Montgomery Shepherd," I introduce myself.

"It's Pamela," she looks up at me nervously. "Since we're gonna be talking about my…you know…may as well get familiar."

"Okay, Pamela, can you tell me how long this has been happening to you?"

"For a few months, I guess."

"How often?"

"About, I don't know, seven or eight times a day?" She looks at me sheepishly.

"Every day?" I hear Izzie ask a little too enthusiastically next to me.

"Dr. Stevens…"

"I'm sorry, every day?" She clears her throat.

"Yes, every day."

"And you haven't seen a doctor about this before?" I ask, jotting down a few notes in her chart.

"It's not exactly something you want to cure though, is it?" George pipes up.

"Dr. O'Malley!" I glare at my interns for their lack of professionalism, even though I'll admit I was thinking the same thing.

"Sorry…"

"I went to my doctor," Pamela admits. "He sent me to a shrink."

"And he didn't do any tests?"

"Pammy? You back here?" I hear a man I don't know call from the doorway.

"Oh God no, you called my father?!" Pamela looks at us incredulously.

"He's your emergency contact person," George responds.

"Pammy? What happened? You were in an accident?"

"I caused the accident, Dad."

"You were having one of your…"

"Episodes," she finishes for him. "Yeah."

Suddenly, she starts to squirm again. Of three of us standing around her bed, my interns look the least surprised. Even as a doctor, the last time I watched a woman have an orgasm was…never.

"Oh no…dang it…" Pamela covers her face with a pillow.

Trying to keep my nausea at bay, thanks to the baby, I look up at Pamela's father. He looks like I feel.

This is going to be an interesting consult indeed.


After my consult, which lasted longer than I would have liked, I'm determined to find Laurie while my interns wait for the lab results. It's after three; she should be done by now.

It's not until I'm walking briskly across the Catwalk that I see him, coming out of Richard's office and followed by none other than my husband. I feel my eyes widen at the sight of Mark Sloan, dressed in jeans and a tight black t-shirt, looking straight at me.

Behind him, Derek gives me the death glare before turning around and heading in the opposite direction. Quickly, I swallow the lump that's formed in my throat. Damn hormones. Damn Mark Sloan.

"What? You're not even a little bit happy to see me?" He chases after me after I turn and walk back in the direction I came.

I stick out my hand to keep him from getting too close.

"Go home. Whatever it is you came here to do, just drop it and leave."

"Hey, we all made mistakes Addison, all three of us, but somehow I lost my two best friends and my only niece."

"Please, Mark," I stop and face him.

"You cheated on him, he cheated on you for a lot longer; Addison, how do you expect to work out a marriage if as soon as there's a problem, he runs away into the arms of some intern?"

"Why are you here?" I ignore his question.

"For one reason. To bring you and Laurie home. I miss you, Addison, and I miss her."

"I'm in love with my husband, Mark, and Laurie needs her father. She came here because she needs her father, and he needs her."

"Oh so that's why he ran off and left her in New York?"

"Mark, please. We are working this out, and you being here…you just can't be here, okay?"

"So instead you have to stay here and be forced to watch Derek interact with his little intern all day?"

"It's not like that. He's…we're working it out. They broke it off, I've moved in with him, and – why am I even telling you this? It's none of your business anyway." I start to walk away again.

"Where is Laurie, Addison?" He asks, catching up with me again.

"She had an appointment with a doctor here this afternoon, I'm going to find her now."

"I'm going with you."

"No, no Mark…just please, go home. Laurie's been through a lot, more than you know, and she just needs some space right now, alright?"

"Addie, stop," he grabs my arm lightly. "What are you talking about? What happened?"

"There was just," I sigh. "There was just some stuff that happened when she came over here, okay? She's working through it. We all are."

"Why won't you tell me about my niece, Addison?" He asks forcefully.

"Because it's not mine to tell!" I almost yell back. "Laurie knows you're here. If she wants to see you she will say so, now if you'll excuse me…" I push past him.

"What makes you think this is going to work out?" He calls. "What makes you think he's not just going to pack up and leave again when things get rough?"

My next move is just about as unplanned as they come. Moving to stand about an inch away from him, I say as quietly as possible…

"Because I'm pregnant, Mark."


That night in the trailer, very little is said between all three of us. I sit at the little kitchen table, nursing a cup of tea while Derek lies on the bed and Laurie sits outside in the hammock with a book. Also, the baby seems to think "morning" sickness actually means "all day" sickness, so I've spent a good amount of time held up in the very small bathroom tonight as well. That makes everything just so much better.

"Derek?" I say quietly, turning around to face him. The expression he gives me almost makes me want to curl up into a ball and die. Obviously, whatever progress we'd made since I got here all just fell to crap with Mark showing up today.

"What?" He snaps. I hear Laurie close her book outside through the screen door.

"I um, I have my first OB appointment tomorrow at noon and, and it's with a new doctor so, will you be able to make it?" I ask him in as nice of a tone as possible. Really, right now, I don't need anything else from him – just for him to be there for his unborn child.

"Yeah, yeah I'll be there," is all he says before looking away again.

Well, I guess it's a start.


I almost forgot how cold the ultrasound gel is, as I lean back in the exam room chair with my stomach exposed. It's been over 16 years since I've been in this position.

Derek stands next to me while Laurie sits in a chair close to the wall. I can tell by the look on her face she's still not happy with me, and it doesn't help that we haven't really had a chance to talk since our fight yesterday morning.

Dr. Jane Harrison, my new OB here in Seattle, very carefully places the wand over my abdomen. I feel my breath catch in my throat when I see the little pea-sized embryo that is my baby. I notice Derek move his hand slightly as he looks at the screen, like he wants to take hold of mine, but he stops himself.

"Addison it looks like you're about seven or eight weeks along," Dr. Harrison smiles. "Heartbeat looks good. But I'm sure everything I tell you isn't anything you don't already know."

"True," I laugh, still staring at the screen. "But I don't think it would be a good idea to let me doctor myself in this situation."

"You should have seen her the last time she was pregnant," Derek mutters.

"It was um, during Med. School," I finish.

"Oh well that couldn't have been easy," Dr. Harrison says, printing off a picture and wiping the gel off my belly.

"Let's just say I was a little paranoid…"

"A little?" Derek looks up at me, incredulously.

"Okay, a lot. But everything turned out alright in the end," I smile, looking Laurie in the eye. For the first time since yesterday, her blue eyes meet my gaze and I feel my heart skip a beat.

Dr. Harrison turns around to smile at Laurie.

"You must be the Med. School baby."

"Present," Laurie raises her hand slightly, still not smiling. "I'm Laurie."

"It's nice to meet you, Laurie. Or should I say 'big sister.'" I notice her flinch at the word sister.

"So um, everything, everything with the baby is okay so far?" Laurie asks quietly, composing herself. Given what happened yesterday and the fact that we still haven't talked, I could almost cry.

"Yep, everything seems to be okay so far," Dr. Harrison responds. "But Addison I'll need you to come back next month for your 12 week check-up, and I'm going to prescribe you your first round of prenatal vitamins. And before you ask anything about age, you're fine. Women have babies in their late 30's all the time."

"You know I wasn't actually going to ask anything about that, but since you didn't assume I was in my 40's, I think I'll let it slide," I smile, sitting up in the exam chair. I think I'm going to like this doctor.

Without so much as a kiss on the cheek, Derek announces that he has to get back to work, only stopping to say goodbye to our daughter. Laurie stands in the corner of the room, waiting for me, but she still doesn't smile or say anything.

Saying goodbye to Dr. Harrison as she leaves the room, I walk over to Laurie and wrap an arm around her shoulders. Honestly I'm surprised she doesn't shove it off.

"I have an hour before my next appointment; you hungry? We could go down to the cafeteria?"

"Sure, Mom. That sounds great," Laurie sighs, walking ahead of me.

Only why don't I believe her?


The next night in the trailer is no chattier than the last. Laurie lay sprawled across her bed with a medical journal while Derek tends to a campfire outside, bottle of beer in hand. I swear, if this family gets any more somber, I am going to go crazy. Except even thought I have to, I don't want to be the one to bring up Mark, the fact that Derek was forced into doing a surgery with him today, or the fact that he can't seem to leave us alone when we need him to the most.

Sighing, I turn and look at my daughter. It's almost scary how much she looks like I did when I was in Med. School.

"Laurie listen, about Mark-"

"I don't want to talk about Uncle Mark right now," she replies, without looking up from her book, as Derek comes back inside.

"Addison the last thing our daughter needs to hear is any of your explanations as to why he's here," he states, sitting on the bed to take off his shoes. It's not even completely dark outside, but no one really has the energy to do anything.

"Well then what do you want to talk about, Laurie?"

"I…" she starts. "I don't want to talk about anything."

Not wanting to push her, I just sit there, looking down at my hands.

"Really, it's you two who need to do the talking," Laurie sits up, with hardness in her voice.

"Laurie, there is more to this than you understand," Derek sighs, running a hand through his hair.

"I understand that Mom cheated on you with Uncle Mark. I understand that you were absent from our lives about 90 percent of the time over the past year, and that you left me to come live in a trailer in the woods. And I understand that you've always assumed that I was just "okay," or that I didn't realize what was going on. Well that's where you're wrong! Do you know how much the two of you hurt me too?! I can't talk to you about this, because if you can't even work out your own issues with each other, why should I get any more involved? I am so tired of being stuck in the middle and I just want it to stop! And I won't let it happen to my little brother or sister either too, so figure it out."

Derek sits there and I swear I see his jaw almost hit the floor. Laurie has never lashed out at him like that before, and up until yesterday, this was pretty new for me too. Opening my mouth to speak, I look at Laurie. Her eyes are swimming, bright blue against the flush of her cheeks. At this very moment, I wish she were five years old again so I could pull her into my arms and tell her never to worry about the silly problems of grown-ups.

"Laurie…" Derek starts.

"No, I don't want to talk to you right now. Talk to her. Work this out." She looks at me, her eyes piercing straight into me. "I'm going for a walk."

Quickly, she grabs a sweatshirt and slips on a pair of tennis shoes.

"Honey wait," I stand up. "Where are you going?"

"Out," she says flatly.

Swallowing the lump in my throat, I try to ignore my shock from seeing my daughter act this way. Granted, I understand why she is, but I've never seen her get this upset at us before.

"Come back before it gets dark, okay?" I reach out to touch her but she backs away, something she's never done before either. That, along with my out-of-whack hormones makes me have to hold back even more tears than usual.

Before Derek or I can say anything else, she's out the door. Turning to face my husband, I feel angrier than I have this whole time Mark has been here.

"This is not fair to her, Derek," I tell him pointedly.

"Look, I'm sorry if the man I found my wife in bed with has me a little bit on edge," he snaps.

"Well what about what I have to face day in and day out? You and Meredith?!"

"That's different and you know it."

"Oh really, Derek? It's different? How is it different? Is it because I cheated first?"

"Meredith and I work together, our relationship is strictly professional."

"Yeah, okay. You say that as if you think Mark and I are in some secret long distance relationship," I raise my voice, using my arms for emphasis.

"I didn't say that," he stands up to wash his face in the sink.

"But you sure implied it. What are we even doing here, Derek? I love you, I really do, and you said you loved me and that you wanted to make it work. Why does Mark coming here have to change that? I made a mistake – a horrible mistake – but I don't love him! I never did, not like that."

"So you've said, Addison," Derek responds after drying his face and sitting down again. "But that still doesn't explain to me why he's here."

"I told you I have no idea why he came here, and believe it or not I told him to leave. More than once."

"Has Laurie spoken with him?"

"I have no idea the answer to that either," I sigh. "Although for her sake, I hope not." I sit down on Laurie's bed and pick up her pillow, breathing in her scent.

A moment later, Derek speaks again.

"We really messed up with her, didn't we?" He asks me quietly.

"Yeah, we did," I sniff, squeezing the pillow tighter.

"We need, I need to do better…"

"No, no, you're right. We need to do better. We can't keep piling everything on her and just expect her to be okay all the time. And we can't do that with this baby either." I move the pillow and place my hand back on my stomach.

"Derek?" I look up at him.

"Hmm?"

"You do want this baby, right?" My voice is quiet.

"Look Addison, I know we fight, and we have a lot of issues to work through, but no matter what happens between us I'll always be there for my children."

I can only hope Laurie knows that.


Thanks so much for reading :) If any of you have suggestions for more events that could happen in this story, please let me know! And I've already started writing 29, so hopefully I'll be able to update sooner rather than later. Oh, and reviews would be lovely :)
