Right, so I fix everything in this chapter! For the most part anyway :) Also, updates from now onwards are probably going to be less frequent than they have been because I'm off to Italy for four weeks this Sunday meaning no internet!!!! I'll try and update with everything I've written so far before I go but after that I can't promise loads... But when I'm abroad hopefully I'll be able to write more so I can update quite a bit when I get back. Anyway, that was all very long and boring and completely off the point of this story. So anyway, read and I hope you enjoy :)

Derek felt the ground beneath him disappear, he felt like he was floating, suspended in a state of disbelief. Pregnant? Lily was barely three months old and already Meredith was carrying a second child…

"I found out today…" Meredith muffled against his scrub top, "Four weeks. I blame your mirror antics." Derek frowned, his guilt sinking in even further. He'd almost broken her again through his own selfish actions and he'd gotten her pregnant and she'd found out on her first day back at the hospital which he'd managed to ruin. He pulled her closer to him and sighed.

"Oh Mer…I have been such an asshole…I promise you that I am going to spend the rest of my life making it up to you, I promise." Derek kissed her hair and she sighed against his chest. He felt his pager go off but he ignored it, knowing that he was needed here more than anything else. Meredith though began to push him off her and he looked down at her with concern.

"What is it Mer?"

"Your pager…"

"I don't care about the pager. I don't care what the pager says. I care about you. I messed up big time today Mer…this is me fixing it. So I'm going to ignore the pager and hug you some more until you believe that I care about you and love you. That okay?"

"Okay… but we need to talk Derek, a lot has happened…we can't just stay hugging forever in here…" Meredith said sadly, wrapping her arms back round Derek. He thought for a moment and then lifted Meredith easily off the ground and wrapped her legs around his waist. She squealed in shock and confusion.

"What are you doing?! Put me down!" Derek chuckled and said nothing. He kicked open the door of the scrub room and walked down the hallway, ignoring the odd looks from his co-workers. He stopped at an on call room and pushed it open with his shoulder and was pleased to find it empty. He walked over to the bed and gently set Meredith on it and sat down beside her.

"Now, you said we need to talk. So talk to me Mer." He kissed her gently and felt her relax.

"Well, I'm pregnant."

"Uh-huh, you said," he said lightly, "Are you okay?"

"I'm okay… shocked, but okay." She paused, "Actually make that scared shitless! Derek Lily isn't even four months old and already I'm carrying a second child! I've only just started working again, I'm already behind the others and this is gonna set me back even further!" She fiddled with her ring and looked away from Derek who waited for her to speak again.

"And then there's you Der…you were an ass earlier outside that elevator. You didn't stick up for me, you didn't introduce me…you say all these wonderful perfect things when we're alone together, you make me feel special Derek… But today you let her assume I was nothing to you. You only told her because I found out…" He opened his mouth to say something but she put her finger on his lips stopping him, "Shh, I've not finished. I don't for one minute think you'd cheat Derek, you know how much it hurts and I know you love me… but you do stupid, stupid things without thinking. I kind of understand, she's pretty right? Really pretty and you felt flattered…but Derek, I'm the one that's supposed to pay you attention, I'm the one that's supposed to flatter you and I don't like that some hot shot doctor was taking that from me…" Finishing her sentence she moved to sit in Derek's lap, wrapping her legs and arms around him, face buried in his neck and he rocked her gently.

"Meredith, if I could take back all of today I would. But Mer, no one could ever take your place. Ever. I was stupid, so very stupid…and Mer, she's not half as pretty as you. She doesn't even compare. She really was just fuelling my ego…not an excuse I know but that's the only reason I let her flirt. I think I missed having a female companion around here… But she could never ever take your place. I love you so much Mer, so very, very much. And I can't believe we've created another life together; do you know how amazing that is? I know it's unexpected but we can do this, it'll be hard but if you want it we can do it. And I promise, no more mistakes on my part. Or at least none of this scale. I promise." He bent and kissed the back of her neck and ran his hand through her hair, clutching her as if his life depended on it.

"You really think we can do this?"

"I do."

"You know this means I'm gonna get even fatter," Meredith giggled making Derek's heart warm, "I'm never gonna be "skinny Meredith" again!" Derek turned her head to face him and kissed her deeply.

"I don't care Mer, and didn't I tell you how much I love your new curves? Which by the way are still incredibly small…"

"You did… I believe that's how I ended up in this mess again!" Meredith laughed, "That's twice now, two accidents. Derek you have to stop jumping me!" She snuggled against him, relieved that they were fixed and fine. Fighting with Derek was horrible and today had been particularly nasty. It would take a while for her to forget his actions but in her heart she knew that he didn't do it on purpose, he's pretty brainless for a brain specialist she thought, and she also knew how guilty he felt; his tears earlier had been a shock and she frowned at the memory.

"I accept your apology Derek… when you say you're sorry over the Alison thing. Seeing you cry almost broke my heart Derek, I don't think I've ever seen you cry before…" Meredith said softly stroking his hair and she looked up at him and kissed him gently.

"I hardly ever do… seeing you so sad though, knowing I was the cause… you just looked so desolate and it did break my heart! I hate it when you're upset Mer, it makes me upset…"

"I'm not sad anymore Derek, you fixed things. You made things better," she sighed happily against him, "I love you Derek."

"I love you too Meredith and I can't say it enough…"

Alison Newton was angry. She was used to getting what she wanted when she wanted. Except Meredith Grey had stopped her. Derek Shepherd was an extremely attractive man and someone whom she wanted to know a lot more intimately. She couldn't believe that such a man was engaged and had a child, with someone she would describe as ordinary. She was a third year resident with ratty hair whereas she, Alison Newton was a world renowned cardio-vascular surgeon with several publications to her name and she was extremely attractive. Any man would kill to be with her. Any man except the one that she wanted. It had plagued her thoughts all through the surgery she had just performed and now scrubbing out it seemed that it would be with her for sometime.

She groaned in frustration and stalked out of the scrub room. She turned the corner and to her horror saw Derek walk out of the OR carrying Meredith into an on-call room. Stupid, tiny Meredith. She clenched her fists angrily and walked to her office, slamming the door shut once she was inside. There was only one thing that would calm her down and that was a call to her best friend. She picked up the phone, praying that he was in.

"Charles Mason speaking."

"Charles it's Alison."

"Darling! I've not spoken to you in absolutely ages! How's it going with that hunky neurosurgeon of yours?" Charles was an old university friend. Witty, bright, intelligent and extremely good looking. They would've been perfect for each other had Charles not been gay. Instead they had formed a fast friendship, both of them ruthlessly ambitious, bitchy and would stop at nothing to get what they wanted.

"He's engaged." Alison sighed down the phone, "To some third year resident with awful hair. They've got a bloody child Charles. He told me we had to stop flirting after I had altercation with his fiancé."

"Your point?"

"My point? My point is that Derek Shepherd is unattainable. And I'm pissed off Charles."

"I still don't see the problem; other women haven't stood in your way before. Steal him darling, we both know you've done it before."

"But Charles you haven't seen the way he looks at her. He practically had a fit in my office earlier, looked as if the world had ended just because this stupid cow was annoyed with him."

"Something to play on then. Come on Alison, you and I both know you're not above it, remember Gregory?" Alison grinned at the memory, getting Gregory had been fun…

"Darling, if you do your magic he'll be in the palm of your hand in months, you know I'm right."

"What about the child?"

"What about it?" They both laughed cruelly.

Alison's pager went off, "Charles, I've got to go. I'll call you in a few days."

"Fine darling, ciao!" He hung up the phone and Alison walked out of her office smiling to herself. Derek Shepherd would be hers; she was sure of it.

At eight o'clock that evening, Derek stepped into the elevator ready to go home. Meredith had seemed much happier when they had left the on-call room. That had been just over 2 hours ago and he hadn't seen her since. They'd agreed to meet in the hospital lobby before he left so Meredith could say good night to Lily and he was on his way there now. The elevator stopped on the third floor and it opened to reveal Alison. Derek groaned inwardly, this was going to be awkward. Alison stepped in and stood beside him. The doors closed and they began their descent.

"So everything happy in paradise?" Alison broke the silence.

"Er yeah…Meredith seems fine now thanks." He paused, "I'm really sorry Alison for what happened. I've been an ass."

"Derek it's fine, you know I could never stay mad at you. We're friends, right?" She said sweetly. Damn he thought, what was he supposed to say to that?

"Of course we are." He flashed her a smile which she returned.

"Good. In that case, care to join me for a drink?"

"Sorry, can't… I've got Lily by myself tonight. Meredith's working, some other time?" Derek felt uneasy, friends inside the hospital was fine, outside not so much. Meredith would not be happy; there was no way he could go for drinks with Alison.

"Of course! I'll come find you tomorrow to organise something." The elevator stopped and they both stepped out; Alison in the direction of the exit and Derek towards the hospital day care. He ran a hand through his hair; he was treading a very fine line by agreeing to be friends with Alison. Meredith wasn't the jealous type; she didn't mind him having female friends just as he didn't care about her having male ones, but Alison had posed a threat to her happiness and it was unlikely she would be comfortable with them being more than just colleagues. Derek sighed; in retrospect being friends wasn't really an option and he would just have to tell Alison tomorrow. Now though was not the time to worry; he had to collect his daughter and say good night to his fiancé.

He picked up Lily and walked back to the hospital entrance and found Meredith waiting for them. Her face broke into a smile and she walked up to meet them. She kissed Derek on the cheek and then eagerly took her daughter from him, hugging her close.

"Hey little girl, mummy has been thinking about you all day," Meredith spoke softly to Lily, "She's gonna miss you tonight…but you have to be a good girl for your daddy." She smiled up at Derek and then kissed Lily on the head.

"You'll be okay with her right?" Meredith asked Derek, "You'll call if you need anything?"

"Mer, you're acting like this is my first time alone with her." He grinned at Meredith who bit her lip.

"I know… I don't know what's wrong with me. I mean I've left her before so really this isn't new…I just haven't been this long apart from her before." Meredith looked down at Lily who had fallen asleep. Derek pulled them both into his arms.

"I know Mer, I know. Lily and I will be fine though, we're gonna have daddy-daughter fun aren't we Lily?" He looked down at Lily and then back to Meredith who was smiling at him.

"Okay." She reluctantly handed Lily back to Derek and hugged them both again. "I'll see you in the morning then?"

"Yup, bright and early!" He turned to walk out the exit and Meredith watched them both leave. Before Derek walked out the door he turned and blew Meredith a kiss and then he was gone. Meredith sighed, running a hand through her hair. It was going to be a long night.

"Meredith!" Izzie ran up to Meredith who was sat on a gurney filling in paperwork.

"Mmmmm?" Meredith said distractedly, "What can I do you for Iz?"

"Go home."

"What?" Meredith looked up at Izzie and saw her smiling, "I can't go home Izzie, I'm on-call."

"Not anymore, I am. I cleared it, so go home, I know you're pining so skedaddle already!" Izzie grinned but Meredith frowned.

"No Izzie, I can't go home. I'm a doctor, I can't just take a rain check, even if I am pining…I will not be mummy-tracked Iz, I refuse." She sighed and shook her head and went back to her paperwork.

"Mer, I'm not mummy-tracking you, I'm not. You've had a pretty shitty day what with Derek being a complete jack-ass earlier," Meredith frowned but Izzie continued, "I know you guys are okay again but you still had a massive fight and you have a really cute daughter and I haven't had a fight or got a daughter at home so really I've got nothing to lose and you've got everything to gain. So go home!" Izzie crossed her arms and looked at Meredith expectantly.

"You're sure?" Meredith said hesitantly.

"I'm sure. I've got Alex to keep me company," Meredith raised her eyebrows, "What? We're just friends, nothing more, nothing less. But that's not the point… The point is you're going home. Now. So give me those charts and get down to the locker room." And she grabbed the charts forcefully and pulled Meredith off the gurney and pushed her away down the corridor.

"Go on!"

"Alright, I'm going!" Meredith started walking away and turned, "Thanks Iz, I owe you!" She called to Izzie.

"No problem Mer. By the way, you might want to tell Derek to watch his back for a while, Alex and George's last plan involved leeches!"

"Will do Iz, will do!" Meredith practically skipped down the hallway to the locker room. She was going home!

An hour later, at just gone midnight a cab dropped Meredith outside her house. She opened the door and dropped her keys and purse on the table in the hall. She noticed the light was still on in the living room. She walked in expecting Derek to be getting a drink or something but the sight that met her eyes was heart-warming. Sat on the sofa asleep was Derek in his pyjamas, head leaned back, his mouth wide open and in snuggled his arms was Lily, who was also sleeping peacefully. The TV was still on, the latest news flickering across the screen. Meredith walked over to them and bent her head to kiss Derek softly. He responded readily and he opened his eyes groggily, they widened with surprise when they saw Meredith, who was now sat beside him.

"Wha-?!" Meredith shushed him with her finger, cocking her head to Lily.

"Iz offered to be on call so I'm home," she smiled at Derek and kissed him again, "I couldn't deny the opportunity to be with my two favourite people. Has she been okay?"

"Kinda, put her to bed at nine and went to sleep soon after. She woke up about an hour and a half ago though and wouldn't stop crying. Tried to feed her but she was having none of it, stubborn little madam. Just waited it out, I must've fallen asleep…" He yawned and kissed the top of his daughter's head, "I think she just missed her mummy." Meredith nodded and carefully lifted Lily out of his arms, careful not to disturb her slumber.

"I'll put her back to bed Der, you go get some sleep." Meredith stood up and walked back out of the living room upstairs hugging her daughter close.

"You're a little minx aren't you Lily? Keeping your daddy up!" Meredith cooed to her daughter as she walked up the stairs, "Did you miss mummy? Because mummy missed you an awful lot..." Meredith sighed, "I hate leaving you baby, but in a couple weeks we'll be off to Connecticut to see Grandma and celebrate Christmas Shepherd style."

She looked down at Lily who was still sleeping and smiled. Meredith walked into her daughter's room and tucked Lily back up. She left the room and found that the hall lights had been turned off. Walking into her bedroom she saw Derek back in bed fast asleep. Quickly undressing, Meredith slid into bed beside him and snuggled close to him. She was just falling asleep when she felt him move and his arms were around her, pulling her body closer to his.

"Night Mer," he said kissing her hair, "I'm glad you came home."

"Me too." And then they were both fast asleep, the day's unpleasant events a distant blur. For now they were peaceful and happy; dead to the world in each other's arms.
