Chapter 14

It had only been a couple of weeks since Mark and Lexie had brought Haley home from the hospital and things were tense around the apartment. Mark had gone back to work, leaving Lexie alone with the baby which was stressful, to say the least. Lexie found herself craving adult interaction. It seemed to her that the only conversations she had lately were with a tiny person who couldn't even manage to stay awake. Work and the baby were also making spending time with Mark more difficult. By the time he made it home, Lexie was beat and by the time Lexie was rested, Mark was heading out the door. It seemed to be a revolving door.

Lexie woke to the shower running. She looked at the clock. 5:15. She knew Mark was getting ready to head in for the day. With a small groan, she rolled over and desperately tried to fall back to sleep. While getting dressed, Mark tried to be as quiet as possible, he didn't want to wake Lexie or the baby since they both needed all the sleep they could get. Before heading out the door, he walked over to where Lexie was sleeping, leaned over, and kissed her. "I'll see you tonight." He whispered. As he walked by Haley's room, he couldn't help but sneak a peek at the little bundle of perfection sleeping peacefully. He gently placed a kiss on her forehead. "I'll see you soon, princess."

It was 6:30 when Lexie heard a small cry on the baby monitor.

"Shhh" she said to herself, hoping Haley would hear her and silence herself.

About five minutes later, it grew louder. With a sigh, Lexie dragged herself out of her bed. "Mommy's coming!" she called. She walked into Haley's room and picked her little girl up.

"What's the matter? Is someone hungry?" She carried Haley with her to the kitchen where she heated a bottle and proceeded to sit on the couch to feed her.

"So, how do you feel about taking a little trip today?" Lexie asked Haley. "You know, Mommy is tired of being cooped up and I know you hate it too. We could go surprise Daddy at work. What do you think?"

Haley just stared at her.

"Yeah, I think it's a good idea too."

After feeding Haley, Lexie changed her and dressed her up in the New York Yankees outfit Mark had bought for the baby right after he found out Lexie was pregnant. She packed the diaper bag, carried Haley to the car, and traveled the short distance to Seattle Grace Mercy West. Walking into the hospital with a baby was strange and surreal. The last time she walked these halls she was a pregnant resident.

"There she is." Dr. Bailey said as she rounded the corner.

"Hey, Dr. Bailey."

She peeked into the car seat. "She is the most precious thing. You did good you know."

"Thank you." Lexie said.

"She is beautiful. Oh, look at those eyes." Miranda gushed.

"Do you want to hold her?" Lexie offered.

"Of course." She answered as Lexie slowly removed Haley from the seat and handed her over to her co-worker. "So how is life with the little one?" Miranda asked.

"Stressful." Lexie laughed. "But I wouldn't change a thing. I am loving every second of it."

"Yeah I know how that works."

Dr. Bailey pager sounded. "I'm sorry. I got to take that."

"Oh sure." Lexie replied, taking her daughter back. "Good luck."

"Congratulations." She told her. "You are both gorgeous."

Lexie looked down at the little girl in her arms. "What do you say we go find Daddy, huh?" She said.

Lexie made her way through the surgical floor and was rounding the corner to Plastics when she stopped in her tracks. She thought she was seeing things but she knew it was real. Mark was flirtatiously chatting with a scrub nurse. The two laughed and entered an on-call room. Lexie was horrified. It didn't take a genius to figure out what the on-call rooms were used for. Especially what Mark Sloan used on-call rooms for. She didn't know what to do. Should she pretend she didn't see anything? What did this mean? She thought she knew him better than this. Without a word, Lexie turned around and rushed out of the hospital. On the verge of tears, she drove home and decided to pack a bag for her and for Haley. There was no way she was staying there tonight. Meredith's place would be fine.

It was about 6:30 that evening, when Mark walked through the front door. He was confused by the bag by the front door. As he walked further into the apartment, he found Haley in her carseat, buckled, and ready to go.

"Lex?" He called. He was nervous. Something about this just wasn't right.

Lexie came out from the kitchen holding a couple bottles and some formula. She paused and looked at Mark for a second before walking past him and shoving the items in the bag. She knew what about to happen and she dreaded it.

"What's going on?" Mark asked, already regretting the question.

"We are going to go stay with Meredith until I can figure out a permanent place for us." Lexie answered.

"What are you talking about? Why are you leaving?" He asked, frantic as Lexie walked away. He grabbed her wrist. "Lexie, talk to me."

"I saw you!" She yelled, unable to keep it in any longer. "I saw you and I don't know what hurts worse, the fact that you did this to me or that you did this to that little girl!"

"Okay, I honestly don't know what you are talking about." He said, blatantly confused.

"Oh, Mark. Don't play dumb. I'm better at it than you." Lexie continued. "Haley and I decided to surprise you, visit you at work. I saw you go into the on-call room with that nurse."

"Oh, I see. You see me go into a room with a woman and you assume I'm screwing her?" He said, angrily. "That's real nice."

"What am I supposed to think?" She asked.

"You're supposed to know me better than that!" He yelled. "Damn it, Lexie. I can't keep telling you over and over that I don't want anyone else."

He sighed. "We had a surgery together. We were tired and we crashed in the on-call room at the same time. That's it."

Lexie looked down.

"When are going to stop judging me for my past? Huh?" Mark asked. "It's like you're constantly looking for any reason to walk away."

"I am holding on for dear life, Mark. I can't do this just for me anymore. I have to think about my daughter now and if there is even the slightest possibility she might get hurt, I have to protect her." She explained.

"Damn it, Lexie. That's not fair! She's my daughter too! You don't think I want to protect her? I would lay my life down for that little girl." Mark shouted.

Lexie bowed her head. "I know. I'm sorry." She sighed. "I think the time apart made me think that you might get bored and then when I saw you go into that room with her then-"

Mark walked toward her and wrapped his arms around her. "You thought that I was getting attention somewhere else?"

Lexie nodded.

"Never going to happen." Mark told her. "The world can try, but it will never happen."

Lexie kissed him softly. "I love you."

"I love you, too." Mark said. "More than you will ever understand. Besides, you have one thing over all the other girls."

"What?" Lexie asked.

"You gave me that beautiful little baby." He said as he kissed her. "You are the mother of my child. You are it for me, Little Grey. Please, don't ever doubt me again."

"I'm sorry. It will never happen again." She promised.

"What do you say we put Haley to bed early so her mommy and daddy can have some alone time?" Mark asked with his gorgeous smile.

"I think that's a great idea." She answered.

Mark unbuckled his daughter and took her to her room where he fed and changed her before placing her in her crib.

"I love you, baby girl. Have sweet dreams." He said before closing the door.

Mark and Lexie spent the rest of the night just talking. Sharing each other's days and filling each other in on what they had missed. They lost focus and lost touch but both were willing to make sure that didn't happen again. They had everything they needed to be a happy family. No one could break it apart.

I hope this chapter was up to snuff. It seemed a little off to me, but it might just be me. Either way I hope you review and leave me your thoughts.

Peace and Love, guys! xoxo
