A/N so here's the next chapter. Bekaroo, I hope you enjoy the Sophia and Lexie bonding! Please read and review

The next few weeks were full of love and spending time together. Lexie felt it whenever Mark looked at her, or even was near her. She had sat in on some of his surgeries, and watching him work, made her feel so special. A surgeon of Mark's skill would want to be with her, Lexie Grey, still amazed her. That, and the fact that Mark was good looking. But the way he looked at her, made her feel like she so special and that he felt he was the lucky one. It also made her feel like she was the only woman that he sees, the only woman that he wants to be with.

One day, they were both supposed to get off at a reasonable time, pick up Sophia and head to the park that was close to Mark's, well their apartment, because Lexie had all but officially moved in. It was going to be a time for all of them to just relax, and spend some time with Sophia. And also it would help Lexie have some bonding time with Mark's daughter. But as Lexie was waiting in the lobby, she received a text from Mark telling her that he got stuck in surgery and to take Sophia to the park and he will meet up with them there.

"I want to add you to the list of people allowed to pick up Sophia." Mark said one day as they were leaving the hospital.

"Really?" Lexie was so touched that he trusted her that much with his daughter. And that maybe Mark was starting to trust her with his heart as well.

"Yes" And that simple answer was all that was needed, as they headed home.

Lexie smiled as she remembered that conversation. So she proceeded to the daycare, where she was able to pick up Sophia. It seemed like every time Mark's daughter saw her, she smiled the biggest smile. And that made Lexie smile and take it as a sign that Sophia liked her. And this time was no exception, because she lit up like a Christmas tree when she saw Lexie enter the daycare.

"We are going to go to the park, and your Dad is going to meet us there. Doesn't that sound like fun?"

Sophia made a happy baby sound.

"Okay, let's get out of here."

They left the hospital and headed to the park and just had fun. Lexie pushed Sophia on the swing; they slid down the slide together, and played in the sand. They basically had a whole lot of fun.

A shadow fell over them as they were in the sand, and Lexie looked up to see Mark there.

"Hey," Lexie said, happy that he was there, but then again, every time she was with Mark, she was happy.

"So are my two favourite women having fun?" Mark asked as he sat down in the sand beside them.

"Yes, we were having a blast."

Mark proceeded to take one of the pails that they had brought with them and use it to make a sandcastle. And he used a surgeon's precision to make it, which made Lexie laugh, and in turn, Sophia.

Mark looked over at them laughing and made a face, but on the inside he was so happy that Lexie and his daughter were bonding. Sophia seemed to love being with Lexie, which had been one thing he was worried about when he got back together with Lexie. It was not just him that she was going to date, he was a package deal. This included Sophia, as well as Callie and Arizona. But it seemed that it was working out that Lexie was accepting of their presence in Mark's life. And it made Mark feel like their relationship had a real chance to work. Mark needed it to work, because Lexie was his other half.

They played for a while longer, until Sophia started to show signs of being tired. Then they packed up their stuff and proceeded home.

They put Sophia down in her playpen, and she immediately curled up and fell asleep.

Mark and Lexie went into the kitchen, where he poured them each of them a glass of wine.

"That was so much fun" Lexie commented.

"I am glad that you and Sophia are getting along so well"

"Well, she is just so adorable and what's not to love?"

"You just don't know how much it means to me that you and she are getting along" Mark said, getting a little choked up.

Lexie went over to him and wrapped her arms around him. "I get it. She is very important to you, which makes her important to me."

"Thank-you" Mark said. And then he kissed her, showing her how much what she just said meant to him. "And I have been meaning to ask you something. Would you move in with me, as you basically live here anyways?"

Lexie was the one to choke up now. "I would love to move in with you."

Mark smiled and then put his and Lexie's glasses down, then took her hand and proceeded to the bedroom to show her how much everything she said and did today meant to him.
