A/N: So aren't you lucky? That's three updates in one day. I won't be able to do any in the next 2 day I think as I will be working, but Monday should bring a new chap.. maybe wedding bells.. or maybe a filler before a wedding chap. I dont know yet. I better get planning. Anyway.. hope you enjoy.. was quite hard to write.. I don't know why. I don't feel the start of the chapter is as good as the end. I just wanted to make Dereks parents aware of the situation and facts, and show Meredith being accepted. I know.. I live in a fantasy world with everything going right for them. So yeah.. have fun!

Please Read and Review and all that jazz.

Thanks for all the great reviews

Take Care as always.

Oh! And I did toy with introducing Mark and Addison in the story somehow.. I even wrote a whole bit for chapter 9 but then thought it was way to angsty as I had promised a happy fic as I want a cute, love, no drama, no hurt, no horrible derek or stupid Mer (when she sleeps with george and stupidness like that) just a nice fic. I hope that is what I am giving you.

And I have already decided the McBaby name and sex.. Can't wait for it!

Take Care once again

Flash Floods

Derek and Meredith sat at the breakfast bar, Luca was napping upstairs. The couple were listening as Fiona, Derek's Mum recounted tales of Derek's misbehaviour as a child. His dad John sat on a stool next to Meredith grinning at his wife.

The three had left Seattle early this morning and arrived just in time for lunch, they planned to spend the night before heading back to Seattle the next night. Derek stood, unable to listen to his mother telling embarrassing stories. He got up and walked around the room, going over to a collection of photos. He smiled, pictures of him and his sisters, the one where they had made him dress as a girl for Halloween, another time forced him to be buried in snow, and one of him buried in snow. His sisters sure liked ganging up on him and they still did it on a regular basis. That's why he had to phone at least one of them a week otherwise he'd have them flying into Seattle thinking he was dead or something.

He picked up a picture of an ultrasound, him and Meredith hadn't had one done yet, but is was dated two days earlier. He turned to his father "Is one of them pregnant again?" he said eyes on the photo, missing the glance between he parents.

"I bet its Sal, she's always pregnant," he looked at Mer, "She has 3 girls and a boy already."

"It's not Sally." his father said.

"So who is it then?" he looked between his mother and father. Neither of them saying anything. "Which one?"

"It's Addison and Mark." Derek froze, his grin fell from his face and he stared at Meredith who was wearing an identical expression.

"You. You have a picture of their..kid.?" he spat. throwing it down on the floor.

"I know she hurt you Derek, but come on, its been two years, you've both moved on." said Fiona walking towards him. "You know Mark is like a son to me."

"Like a son? Yeah right. He slept with my wife and he – "

"No Derek." Meredith said jumping in. Knowing exactly what her fiancé was about to say. "You can't tell them."

Fiona and John looked at the couple, Meredith had her hands on Derek's arm, looking him in the eyes.

"Tell us what?" said Fiona.

Derek knew it wasn't his place to say. But he wanted his parents to know. Meredith saw this and sighed.

"This isn't my choice" she said to the three of them. "Derek check Luca is asleep." she ordered. Derek meekly ran up the stairs before reappearing and saying he was. Meredith looked at Derek's parents. She'd only known them a few hours and now she was ratting on their other 'son'. She sighed again.

"I want you to remember Derek, and you too. You've asked. I don't want to say, but you can't tell anyone and this.. you can't hold this against me. You wanted to know."

Fiona and John nodded. worried about the serious look and tone of their sons fiancé.

"I know Mark. He." Meredith looked Derek straight in the eyes, unable to look at his parents. Drawing strength from him she told the story which she had told Derek the night when Luca had hurt himself. Finishing she said "I told Mark I was pregnant, Addison even delivered my baby. But he didn't want to know. said he wasn't the father type, he wasn't in love with me he loved the girl he was with. Luca was that baby."

Fiona and John looked at each other shocked that their adopted son would be so callous.

"Oh my!" said Fiona.

Derek walked towards Meredith, turning he faced his parents. "That's why I'm upset. Not because of Addison. But because Mark hurt Meredith. He broke up my marriage, and left Mer to raise Lucas on her own. He left his own child because he was too busy screwing my wife!" he breathed in heavily.

"I'm sorry" said Meredith.

"No." said John. "You shouldn't be sorry. You did the right thing. We asked. Now we know."

Meredith felt tears stream down her face. "But now you think I'm a dirty whore who gets pregnant with both your sons. But I loved Mark. I did. And then when I held Luca.. I stopped loving him. In that one moment. I stopped. I hated how he could turn away from something.. someone as perfect as my son. And then.. there was no-one until I met Derek. And I fell in love with him. and I love him more than anything. he loves me and my son. He is Luca's dad."

Meredith leaned into John as his arms came around her, reminding her so much of her own father. "We don't think that. You are a lovely girl and a wonderful mum. Derek is lucky to have you." he smiled. Fiona came over and put her hand on Meredith's shoulder.

"John is right. We should have listened before when Derek said. We're sorry for making you go through that again. But thank you for telling us. We're really happy you're joining our family." she smiled at the blonde haired women, and could see why her son had fallen so hard for her.

The next day passed quickly and soon enough Derek, Meredith and Luca found themselves at the Airport. The drama of the day before had been forgotten, and the family had had a wonderful time, getting to know each other and talking about Luca and wedding plans. Fiona and John especially loved how Luca would sometimes say "Daddy Derek" which they both found amusing.

"Bye bye Grandpa! Bye bye Grandma!" said Lucas, happily hugging his new grandparents.

"It was lovely meeting you" said Fiona, wrapping her arms round Meredith, before letting go.

"You're a wonderful woman. And if my son hurts you I'll come beat the crap out of him." said John.

Meredith laughed as Derek muttered "You wish."

"What was that son?" he said squaring up.

"Uh.. Nothing Dad."

The group laughed at the two doctors, father and son, as they hugged goodbye.

They turned to move off before John called out, "Derek I forgot. New cap."

He chucked the package to his son who caught it.

"What it got on it?" asked Luca, peering up.

Derek tore it open and looked at it before glaring at his father. "How did you know?" he asked, before turning to Meredith "You told them?!" he cried.

Meredith smiled and kissed him on the cheek. "You didn't answer your phone a few weeks ago. Suck it up baby."

"What is it?" asked Luca, tugging on Derek's sleeve. "Daddy?!"

Fiona and John smiled at the little boy calling their son Daddy, and watched with pride as Derek knelt down beside Luca and showed him the dark blue hat which would match his scrubs, except for the white lettering of MCDREAMY written across the front.

"It says "McDreamy" on it."

Even Luca knows the importance of that word. "That's what Auntie Cris calls you!"

"That's right Little man. Mean women!"

Fiona and John waved goodbye to the family with promises of calling and wedding invites coming soon.

Sat in their seats, Luca was asleep sprawled across Derek's stomach. Meredith pulled a package from her pocket.

"I got you a present too." said Meredith, "I got you're Dad to get it for me."

Derek took the package carefully managing not to wake Luca when moving his arms. He pulled the wrapping off and this time pulled out a white scrub cap with white writing on it saying "I'm McDaddy." He smiled at Meredith, and she kissed him as he couldn't move for the dead weight of Luca.

"You're McDreamy McDaddy." said Meredith laughing.

"Shut up" he said glaring at her but with a twinkle in his eyes.

They both drifted off and the three slept their away across the country.
