Chapter One

Meet and Greet

Meredith looked around at the decorated church. She was amazed how beautiful the place looked. She turned to her nervous sister. "What do you think? Is it too much? After all, I want everything to be perfect for tomorrow," Lexie told her.

A small voice spoke up. "I love it, Aunt Lexie."

Meredith and Lexie exchanged smiles before they turned to the little blonde girl standing besides them. "Thank you, Morgan," Lexie replied. "I'm glad you think so." She then turned back to her sister. "It's too much, right?"

Meredith shook her head. "No, I think it looks great," she assured her. She gave her sister a comforting smile. "You need to stop stressing out. Your wedding is going to go off without a hitch tomorrow."

Lexie sighed. "I hope so."

"It will. I will make sure nothing ruins your wedding," Meredith promised her. "Now is there anything else I can do for you or Mark before the wedding?"

Lexie nodded. "Do you remember Mark talking about his best friend Derek Shepherd all the time? The one back in New York City?"

"Of course. His daughter Katie is the same age as Morgan," Meredith replied. She had never met either of them, but had heard Mark talk about them often enough. He always visited them and brought back tons of pictures especially of Katie, who was his goddaughter.

"I've arranged for Derek and Katie to fly in as a surprise for the wedding. Their plane is coming in tonight and I was wondering if you could pick them up for me," Lexie told her. "I know it's last minute, but Derek couldn't decide whether he was coming or not. And he had to convince his ex-wife to let Katie come along."

Meredith sighed. "Alright, I'll go pick them up. What hotel did you set them up with?" she asked.

Lexie turned red. "Actually, I told him that they could stay at our place."

Meredith gave her a look. "And you never thought to ask me if it was ok to have guests in the house?"

"I'm sorry. I was so busy with the wedding plans that I forgot to consult with you about Derek and Katie," Lexie replied.

Meredith nodded understandingly. "It's ok. It's fine. What time does their flight get in?" she asked her.

Lexie looked at the time. "You should go now."

"Alright. Why don't you take Morgan home and I'll see you there after I pick up our guests?"

"I want to come with you," Morgan protested. Meredith agreed and she took her daughter's hand. They quickly said good-bye to Lexie before leaving the church and heading to the car.

They were soon at the airport, waiting at the proper terminal for Derek and Katie to arrive. Meredith was a little nervous meeting Derek. She had heard such great stories from Mark about him that she hoped that he was just as kind, caring and funny as Mark said he is. She also hoped that Morgan and Katie could get along especially since they were sharing "Uncle Mark".

Meredith then looked up and saw a man and a young red-headed girl walking towards them. She knew it was them from the pictures that Mark had showed her. She grabbed Morgan's hand as they got up from the chairs.

Meredith was relieved when Derek gave her a smile when he recognized her. She was about to point him and Katie out to Morgan when she noticed that she was hiding behind her. She wasn't surprised since Morgan always had been nervous about meeting new people.

"It's ok, Morgan. They're Uncle Mark's friends," Meredith told her gently as the man and the little girl approached them. "You must be Derek and Katie." Derek nodded. "I'm Meredith Grey and this is my daughter Morgan," she said as Morgan poked her head out to see the newcomers.

"It's nice to meet both of you," Derek replied as he gave her a wider smile than before. "Mark has told us so much about you two and Lexie, of course." The two parents turned to their daughters, who were looking at each other nervously. "Katie, say 'hi'.

"Hi," Katie said quietly.

"Well, let's get your suitcases and get back to the house. We'll be able to get to know each other then," Meredith said as she led them towards the baggage claim. Neither child was willing to let go of their parent's hand.

There was an awkward silence before Derek decided to speak first. "So what did Mark tell you about me?" he asked her as they walked through the crowd.

"He didn't talk about you as much as he did about Katie," Meredith replied as she gave a smile to the little girl. Katie smiled in return. Meredith then noticed the upset look on her daughter's face. She then turned to Derek as she gestured to Morgan. "How about you tell me about yourself first? Then we'll talk about what I already know about you and Katie?" she asked him hopefully.

Derek looked at Morgan before agreeing. "Where should I begin? Well, I grew up with four sisters. I'm a high school biology teacher. And I'm the father of two lovely children with Katie being the oldest. Is there anything else that Mark told you about me?" he asked her as he grabbed his suitcase off of the luggage carriage.

"Why do you want to know so badly?" Meredith asked her. "Are you afraid that he said something bad about you?"

Just then, they heard a small voice. They looked down at Katie, who was tugging on Derek's pants. "Daddy, I see my suitcase," she told her father as she pointed to the suitcase with The Little Mermaid characters on the front of it. Derek pulled it off and brought it over to his daughter.

Meredith gave Katie a wide smile. "I see that you like The Little Mermaid," she noted.

Katie nodded. "Yep."

"She's crazy for that princess," Derek added. He turned to Morgan. "So which princess do you like?"

"Aurora," Morgan replied shyly.

"Daddy, I'm hungry. I want something to eat," Katie whined.

"Do you mind if we stop somewhere to get something to eat? We didn't have much on the plane," Derek told Meredith.

"Just no peanuts," Katie added.

"Katie is allergic," Derek told her.

Meredith nodded understandingly. "It's no problem."

After grabbing a bite to eat, they were on their way to the house. Derek and Meredith Once they arrived at the house, Lexie was there to greet them. She had Prince, their German Shepherd puppy, with her.

Katie was excited when she saw him. "Daddy, can I play with the puppy?" she asked eagerly.

"He's my puppy," Morgan said angrily.

"Morgan, maybe you could play with Prince together," Meredith suggested. Morgan seemed satisfied with that answer. She didn't say anything as her mother helped her out of her car seat. Derek did the same with Katie. "I'm sorry about that. It's hard for Morgan to share since she's an only child," she explained as the children ran off with Prince.

Derek nodded understandingly. "I know what it's like. I had the same problem with my sisters. Katie does too." He then turned to Lexie who was walking over to them. "This must be the famous Lexie. I'm Derek Shepherd and the little girl playing with Morgan is my daughter Katie."

"It's so nice to meet you. Thank you for coming," Lexie said.

"Thank you for inviting us. I'm sorry that it was last minute though," Derek replied.

Lexie shrugged. "Don't worry about it," she told him. She quickly changed the subject. "Do you need help with bringing your suitcases in?" she asked him.

Derek shook his head. "No, I think I got it," he replied as Meredith popped the trunk. "I can't thank you two enough for letting us stay with you girls. I'm sure it's crowded already with the wedding guests."

"No, we're happy to do it," Lexie replied as Derek pulled the suitcases out. He followed her onto the front porch and into the house while Meredith went to watch the girls play in the backyard with Prince.

After awhile, Meredith sent the girls inside. The parents could see that the two little girls were getting along better now. Meredith was relieved. She wasn't surprised though. She knew that Morgan had made a new best friend. She even wanted Katie to sleep in her room. Katie didn't object and a sleeping bag was soon set up in the bedroom. Once it was bedtime, Meredith read them a story before she tucked them in with each of their favorite dolls. Derek then came in and kissed his daughter good-night. Meredith did the same with her own daughter. The night-light then plugged in and the two parents left the room.

"I'm glad that Morgan and Katie are getting along now," Meredith told him once they arrived back downstairs to the kitchen. "I didn't think they would at first."

Derek turned to her. "What about us?" he asked her.

"I wasn't too sure about us either," Meredith admitted. "But I didn't want to judge you before getting to know you."

"To be honest, Mark didn't really say much about you except you are a very private person," Derek told her.

Meredith couldn't argue with him on that. "Well, he's right. You really don't want to know me. I'm all dark and twisty inside."

Derek laughed. "Dark and twisty? Where did you come up with that?"

"Laugh all you want, but it's true," Meredith replied.

"Let me be the judge of that," Derek told her.
