Derek walked into the house carrying a sleeping Ally and his jaw almost hit the floor as he stared at clothes scattered all over the living room, food scaps all over the kitchen and dirty pans in the sink, he could hear the shower running and after carrying Ally to her bedroom he came downstairs just as Mia came dancing into the kitchen wearing a towel, "hey d man what's up."

Derek stared at Mia with a frown, "I think you should be telling me what's up have you seen the mess."

"Oh" Mia did a quick spin around, "well dude what did you expect i'm a teenager this is kind of what we do."

"I was expecting" Derek sat down on a chair, "to come to my house and not have it look like a bomb hit the place."

"Don't sweat it shepherd" Mia said with a casual smile, "I was going to clean it up."

"When were you planning on doing that, right after I got home?"

"Okay okay" Mia raised a hand in defeat, "i'm going to clean up everything right now."

"Mia you didn't have a party here did you?"

"Nope ah technically a few friends isn't a party" Mia chuckled at Derek's face, "dude i'm totally kidding." Mia opened the cupboard under the sink and bent over to grab a cloth and Derek quickly turned away, "and in future could you walk around my house wearing a full set of clothes."

Mia got up and smirked, "okay d man" as she dashed off to the bathroom.

"And stop calling me d man" Derek heard a yelp and he dashed through the trailer to find Ally thrashing around on her bed, "daddy daddy."

"Ally" Derek patted Ally's forehead "calm down its alright."

"Daddy" Ally yelped loudly.

"Its alright i'm here wake up, i'm here Ally your having a nightmare."

Ally opened her eyes and looked around her, "where am I?"

"Your home" Derek smiled, "we came home from the camping trip and you fell asleep in the car and then I brought you to your bedroom."

"Oh" Ally said softly.

"You want to come and watch tv."

"Okay" Ally said as she and Derek walked into the living room and Ally gasped, "wow."

"I know" Derek muttered as he looked at the dishes, clothes and food scraps, "Mia has been a bit messy."

Ally looked up at Derek with wide eyes, "this looks like Oscar the groach's house."

"Hey" Mia poked her head round the corner.

"Mia" Ally said excitedly as Mia ran and gave her a hug.

"Hey bumblebee, did you had fun?"

"It was lots of fun" Ally grinned at Derek, "I love camping."

Mia rubbed Ally's head, "was your daddy well behaved."

"He's always good."

"Cool" Mia said smiling at Derek, "hey d man I made you a drink."

"A drink" Derek raised an eyebrow as he took a glass with a strange looking liquid, "Mia if this is alcohol I don't drink it when i'm around Ally and I expect you to not do the same."

"Its just a shake" Mia muttered, "I brought this mixer from home and I put a lot of healthy crap in it you'll like it."

"Mia please don't swear in front of Ally."

"Oh shit" Mia stammered, "oh ah of course captain."

Derek stared at the mixture and his nose twitched the smell was terrible he sat it down on a table before sitting down on a recliner and after he turned the television to a children's channel Ally climbed into his lap and turned her head to look up at him, "daddy."

"Yeah."

"Will you be my daddy forever?"

Derek turned down the television and drew an arm around Ally, "well that's a out of the blue question why do you ask?"

"In my nightmare you were gone" Ally said in a soft voice, "and I wasn't going to see you again."

"Ally" Derek kissed Ally's forehead, "no matter what happens i'm always going to be your dad and no matter where I am you can find me in your heart."

"In my heart" Ally repeated.

"Yeah, and please don't tell Meredith how sappy I can be okay."

"What's sappy mean?"

"Um" Derek tried to think of a good definition before he shrugged, "you know what I don't know what that word means myself."

Ally smiled and cuddled up close to Derek, "I love you daddy."

Derek gave a nod as his hand patted Ally's knee, "I love you to Ally."

A few hours later Ally had fallen asleep on Derek and Mia had walked into the living room with sweaty hair matted to her forehead, "okay everything is clean sorry about the mess and-"

Derek stared at the girl and noticed that Mia's eyes were red and puffy as if she had been crying, "Mia are you alright?"

"Yeah" Mia said with a unconvincing shrug.

"Mia i'm not that mad about the mess and i'm not going to fire you for this, the kids love having you here."

"Cool thanks" Mia walked over and put a gentile hand on Ally before she started to wander to the door and turned back, "you really love Ally don't you."

"Yes" Derek said simply then he remembered he hadn't taken a sip of Mia's beverage, "oh the drink sorry."

"Wait wait don't drink it, its probably rotten by now" Mia took the glass from Derek before she dashed to the kitchen and poured it down the kitchen sink.

Derek watched her intently, "are you sure everything's okay?"

"Yeah" Mia muttered, "you know your a really nice guy mr d."

"Thank you that's nice of you to say that Mia."

"Okay well see you tomorrow" Mia went rushing out the door and Derek stared before lifting the still sleeping Ally in his arms he went to close the door, "I don't know how i'm going to go when Ally reaches her teens" Derek carried Ally back to her bedroom, "i'm going to need a book called how to manage your teenagers."

Meredith wandered into the hospital and was greeted by Alex staring at her with a sick look on his face, "hey hotness where have you been the last few days."

Meredith frowned her dislike of Alex had nothing but deepend over the last few months, it had something to do with him learning about her relationship with Derek and the rest of it was because of his sexist attitude, "its none of your business Alex."

"I'm just showing an interest" Alex smirked, "you know if the gardener has taken all your money I can always lend you some more."

"Derek Shepherd is not after my money."

"Well for now" Alex replied.

"He's a good man who treats me and my son very well."

"Oh your son Nevelle"

"Noah" Meredith corrected him.

"Noah" Alex said, "so anyway Derek hasn't been snarling after your bank fund like a hungry wolf yet."

"Alex" Meredith glared at her colleague with fury.

"Hey I just don't want to see you get hurt that's all."

"No you don't" Meredith challenged, "that's not even in the back of your mind."

"Well" Alex walked in to close to Meredith's comfort and placed a hand on her arm, "i'm always keeping an open mind."

"Okay" Meredith felt Alex's hand descending south and she swatted it away, "lets get one thing clear I am not attracted to you, I never have been attracted to you and I never will be, you know why."

"Well" Alex smiled smugly, "I can't think of a reason."

"Its because your a pig, you just want to sleep with me."

"Baby that's not true at all, I want to be good to you and treat you better than some tramp can."

"No" Meredith swatted Alex's hand away, "you don't just back off."

Meredith hurried to her office and threw her books on her desk and took a deep breath letting out all her anger before she quickly hurried to meet her first patient. The day went by slowly at the hospital Meredith did her best to concentrate but all she could think of all day was Derek that argument with Alex had made her want to reflect on Derek, how much she wanted to be with him how strong her feelings were for him. Her shift finally finished late into the night and making up her mind she sent a message to Cristina and started to drive to where she wanted to go she knocked on a door and a minute later Derek wearing pyjamas answered, "Meredith its after midnight." Meredith closed the distance between them and kissed him passionately running her hands up and down his back she pulled back and Derek stared at her before he leaned in to kiss her as Meredith wrapped her arms around him.

Meredith briefly broke apart to take her coat off, "is Ally asleep?"

"Yes" Derek said as he quickly looked towards Ally's room and stumbled back as Meredith kissed him again.

"Good" Meredith's fingers dove to Derek's shirt.

"Meredith."

"Shut up" Meredith threw off his shirt and ran her hands up and down Derek's muscular torso.

"Okay i'm shutting up" Derek said as he led Meredith to his bedroom he closed the door and kissed Meredith using his hands to remove her clothes his lips descended to her neck as Meredith moaned in approval "your so amazing" Derek whispered.

Meredith's hands descended to Derek's panths to pull them down and within a minute Derek had lied her down on his bed.

The next morning Meredith rolled over on her side and drew an arm around Derek's naked body as Derek opened his eyes and smiled at a smiling Meredith, "well that was an unexpected surprise."

Meredith kissed Derek, "I felt like you deserved a surprise."

"Well i'm not complaining one bit."

"You know all I could think about yesterday was how much I wanted to be with you."

"Funny enough I was thinking the same thing."

The door quickly opened and Meredith and Derek's eyes darted as Mia came in, "hey d man I woah" Mia's eyes popped out as Meredith drew her sheet to her naked chest almost completely pulling it off Derek who quickly grabbed the rest of the sheet to cover his midsection.

"Mia" Derek said to stunned to think. Mia covered her eyes and turned away, "guys i'm glad your getting some but did you ever think of a hotel."

"Daddy what's going on woah" Ally said as Mia quickly covered Ally's eyes with her hand as Derek's mind raced like the handles of a broken clock trying to think of the perfect lie, "its okay Ally Meredith just spent the night we had a slumber party."

"Yeah" Mia added as she led Ally into the hallway and closed the door, "and they forgot their pyjamas" she added in a loud voice.

"Oh" Ally muttered.

"Come on bumblebee lets have breakfast."

Derek looked at Meredith with eyes blazing with laughter, "well that was."

Meredith looked through her clothes for her watch, "what time is it?"

"Its six thirty" Derek said looking at his own watch.

"Shit" Meredith stammered as she sorted through her things, "I got to get Noah to school"

"I better do the same with Ally" Derek grabbed a shirt off his chair, "I guess I can't convince you to stay for breakfast."

"That's usually" Meredtih stammered as she threw on her underwear and work clothes, "what I like a man I sleep with to do for me the next morning."

"Are you mad" Derek said.

"Furious" Meredith smiled as she planted a kiss on Derek's lips and quickly brushed her hair.

Meredith and Derek came running into the kitchen ten minutes later to find Mia smirking and shaking her head at the pair of them and Ally smiling like she did every morning she saw Meredith and Derek, "hi honey" Meredith said to Ally.

"Hi Meredith" Ally said.

"Hi Mia" Meredith said as she turned her gaze to the teen.

"Hi doc" Mia replied.

Meredith had never felt so awakered in her life she was turning red and didn't know what to say, "bye" she said as she headed for the front door.

"Bye Meredith" Ally waved.

"See ya doc" Mia added.

Six hours later Meredith and Derek were sitting in the hospital garden during their lunch breaks giggling like small children on Christmas morning as they talked about last night, "well that was" Derek started.

"A weird morning" Meredith finished.

"You know Ally was asking me as I was getting her ready for school about slumber parties and why grownups have slumber parties in the nude and then Mia decided to ask me where do babies come from and Ally was like, yeah daddy where do babies come from and I just-"

Meredith laughed with Derek as Meredith took his hand, "come over tonight and bring Ally lets have a sleepover."

Derek gazed at Meredith, "are we going to introduce nude slumber parties to Noah?"

"No honey" Meredith replied with a soft kiss, "just for a ah cucumber sandwhich"

"Sounds great."

"And lets tell the kids the truth."

"About us?"

Meredith nodded, "I think its time."

"I agree."

The plan to tell the kids about their relationship that night didn't go as Meredith had planned emergencies had caused her to work overtime and at 10.00 at night she finally came running through her front door to find Derek washing the dishes, "sorry i'm late."

"No its okay" Derek said as he got Meredith a glass of milk.

"The kids" Meredith asked.

"They fell asleep."

Meredith sat down in a chair and groaned.

"I didn't tell them" Derek said as he sat down and drew an arm around Meredith.

"Well I guess we got to wait until tomorrow, as long as my shift tomorrow doesn't go late into the night again."

"Hey its alright" Meredith gave Derek a long slow kiss and there was a gasp at the top of the stairs they both pulled apart and looking up they saw Ally looking through the bars wearing a very wide grin on her face, "Ally" Derek started.

Ally ran down the stairs and grinned from ear to ear as she looked at Derek and Meredith, "you were kissing."

"Yes Ally" Derek said as he rubbed the sleep out of his eyes and prepared himself for a serious talk, "we were kissing can you sit down we need to."

"Noah" Ally called out as she started to run to the stairs, "Noah."

"No no" Meredith dashed forward and grabbed Ally around the waist, "wait wait Ally."

"Noah No mmmph" Ally felt Meredith's hand on her mouth just as Noah came walking through the bedroom door rubbing his eyes, Meredith quickly carried Ally to the living room just as Noah finished rubbing his face, "Derek what's going on?"

"Ah nothing mate."

"Where's Ally?"

"She is on the toilet."

"Oh" Noah muttered as he looked at Derek before heading back to his bedroom, "bye."

"Goodnight mate" Derek said before he went into the living room to find Ally jumping around and Meredith trying to calm a excited six year old down.

"Ally listen to me."

"You were kissing each other" Ally sang as she danced, "you were kissing each other."

"Ally" Derek muttered he couldn't help but grin his daughter was making him laugh.

"Your falling in love, your falling in love."

"Ally look we're" Meredith stammered, "your daddy and I are dating and we were going to tell you tonight but I was late coming in from work."

Ally climbed on Meredith's knees and sat with her knees on Meredith's as she smiled while staring at her, "when are you getting married?"

Derek let out a loud cough, "Ally we're not getting married."

The smile slowly faded from Ally's face, "why not?"

"Ally" Meredith said as she wrapped her arms around Ally, "we're only been together for a few months."

"You went on" Ally said slowly as she thought to herself, "lets see two and a half dates so it would take half a date for marriage cause three is the magic number."

"Professor Ally cat" Derek sat on the sofa beside Meredith, "we've been out on a few more dates than that."

Ally furrowed her eyes, "were you kissing before?"

"We were for a bit."

Ally's jaw dropped, "and you telling me this now?"

"Well Ally" Derek looked at Meredith, "we were just waiting for the right time to you know tell you and Noah."

"We didn't want you to get your hopes up" Meredith added.

"So your not getting married."

"We might get married someday" Derek put a hand on Meredith's arm, "if we fall in love."

"How long is that going to take?"

"Well it takes a bit of time" Meredith said softly, "you know how a tree grows that takes a while so-"

Ally made a dramatic face, "its going to take a hundred years."

"Well no" Meredith smiled, "probably a bit less if... look Ally can you not tell Noah that we are kissing and are dating."

Ally sighed, "but I want to-"

"Ally" Derek leaned forward, "Meredith needs to tell Noah this cause she is Noah's parent, just like i'm telling you about us kissing as I am your parent."

"What about friends telling friends things?"

"Ally" Meredith said.

"But Meredith."

"Ally please."

"Okay" Ally sighed as she climbed off Meredith.

"Thank you."

"Wait" Ally jumped up, "are you going to keep going on dates?"

"Ally" Derek let out a chuckle and a smile, "we are going to keep going on dates you don't need to make deals with us or blackmail us or anything like that."

"Just checking" Ally grinned, "when you decide to get married can I tell Noah?"

"Honey" Meredith pointed at the clock, "its way past your bedtime."

"Okay goodnight lovebirds."

Meredith watched Ally jump up the stairs, "she's a funny little thing your daughter."

"Hey she's adopted" Derek replied, "I don't know where she got her sense of humour from."

"You must have taught her it."

"Me ah hey you think i'm funny?"

"Of course darling."

The next day Meredith had come to Derek's house to drop off Noah and was greated by Mia opening the door, "hey doc what's up."

"Hi Mia" Meredith smiled, "is Derek home?"

"One second" Mia opened the door and shouted, "d man doc is here."

"Hi Mia" Noah said shyly.

"Hey little guy" Mia picked Noah up and spun him around, "did you grow last weekend."

Noah grinned and Mia looked at Meredith, "what are you waiting for an invitation come on in."

"Okay."

"D man get your ass out of the shower, you got guests."

"Mia" Meredith watched Noah running to greet Ally, "could you please not swear in front of Noah."

"Oh shit sorry fuck, um sorry okay I'm shutting up now hey there he is hey d man."

Derek came running in rubbing his hair with a towel, "Mia could you give us a minute."

Mia smirked, "hey if you guys want to snog you can do so in front of me."

"Mia" Derek started.

"Don't be embrassed d man you and doc make a good couple."

"Mia you know you don't have to babysit today."

"Okay d man i'm going" Mia said goodbye to the kids before wandering out the door.

Derek smiled, "how are you."

"Good" Meredith said simply as she smiled.

"Have a good day at work and i'll see you tonight."

"I'll be home before the kids bed time I promise."

An hour later Derek had taken Noah and Ally to the park and was lying on a bench daydreaming to himself he heard Ally calling him over to the swings and with a stretch he got up and wandered over to give the kids a push. Derek absent minded pushed Noah and Ally on the swings until Ally's voice interrupted his relaxed state of mind, "daddy."

"Yeah."

"What do grownups do when they're in love."

Derek's senses shifted to full alert as he saw the cheeky grin on Ally's face, "well Ally they um they spend a lot of time together and they say nice things to each other."

"What happens if they have kids?"

"Well" Derek said as he tried to think of a good reason.

Ally giggled, "do they tell them they're in love."

"Yes Ally they do if they actually are in love and its the parents who should tell the kids."

"So if a little boy saw his mommy and a man like um you kissing."

"Then the mommy" Derek smirked, "would tell the little boy and only the mommy."

"What are you talking about?" Noah said looking confused.

"Nothing mate just you know talk between Derek and Ally."

"Oh" Noah muttered, "Ally can we go on the seesaw."

"Okay" Ally said as she jumped down and followed Noah with Derek trailing her, "I know what your doing you sneaky sausage."

"What" Ally said with a smile.

"Your telling Noah that me and Meredith are a couple without telling Noah that me and Meredith are a couple."

Ally smiled wider, "Ah...yeah."

"Well it ain't going to work."

"Yes it will watch this." Ally jumped on the seesaw and looked at Noah, "Noah what do you think about kissing."

"Um" Noah said looking uneasy, "I don't know."

"Do you think its romantic when grownups do it?"

"I think you get cooties."

"No Noah when grownups kiss they fall in love."

"Oh okay."

Derek started to snigger as Ally continued, "its good isn't it."

"Can we play in the sandpit."

"Okay" Ally said looking dejected.

"That sounds fun" Derek said as he gave Ally a thumbs up and Ally pulled a funny face at Derek.

The rest of the day sailed by until seven o clock when Meredith came rushing through the door checking her watch and clutching her side,"I made it."

"You did great" Derek looked at the clock, "the kids are watching tv."

Meredith nodded as she caught her breath, "hi."

"Hi" Derek said before Ally came into the kitchen huffing and said in a dramatic voice, "okay its been a whole day since I found out your kissing are you going to tell Noah now?"

Meredith smiled, "yes Ally I am going to tell him now."

"We both are" Derek added.

"Can I watch?" Ally asked.

"No honey" Meredith replied.

Ally made a farting noise with her lips before she returned to watching the tv.

"Noah" Meredith called out, "can you come here."

"Yes mom" Noah came running into the kitchen and Meredith and Derek pulled up chairs and sat down.

"We have something to tell you" Meredith started.

Noah's eyes widened "is it bad?"

"No mate its good news" Derek said, "well we think its good news and we hope you think so to."

"You know how me and Derek spend a lot of time together."

Noah nodded, "yeah."

"Well the reason is because me and Derek are in a relationship."

"What does that mean?"

"It means we kiss" Derek smiled at Meredith, "and we care about each other very much your mommy is my girlfriend."

"Oh" Noah said as he looked at the living room, "can I watch tv now?"

"Do you have any questions?" Meredith said.

"Nope."

"Are you okay if your mommy is my girlfriend?"

"Yeah."

"Alright honey go and watch tv" Meredith watched Noah disappear and she turned to Derek, "well."

"Not quite as excited as Ally was but he seems fine."

A minute later Noah ran back into the kitchen with an open mouth, "your getting married" he said loudly.

"No no mate" Derek said quickly, "we're not we're... Ally."

Ally looked up wearing a wide wicked grin, "what?"

Derek gritted his teeth before he stared with a calm expression at Noah, "we're not getting married."

"You are some day" Noah said loudly.

"Well if we get married" Meredith took Noah's hands in her own, "we will ask you first if its okay."

Noah let out a sigh, "phew."

Meredith lifted Noah on to her lap, "what's phew?"

"I thought you were going away to live in a castle and leave me behind."

"We're not" Derek said as he chuckled.

"Your still my mom" Noah looked at up at Meredith who kissed his forehead, "I will always be your mom"

"Okay" Noah hopped down and breathed deeply, "phew its okay its fine." Noah went back into the living room and Derek and Meredith chuckled and laughed at each other.
