Chapter 6

Wow. She couldn't actually comprehend it. She was engaged, getting married, a fiancee. No matter how she worded it, it scared her all the same. Was she ready to be a wife? Lexie hated that these thoughts crept into her mind all the time, but she couldn't help it. Wasn't it only natural to have doubts? Lexie had finally had enough and decided to leave the suddenly small apartment and go someplace a little more comforting.

She pulled up Meredith's driveway and walked in the front door that was still so familiar.

"Mer?" Lexie called out.

She heard silence.

"Meredith?" She tried again.

Derek made his way from the kitchen. "She isn't home right now."

"Oh...I'm sorry. Um...When will she be home?" Lexie asked uncomfortably.

"I'm not sure, she took off with Cristina so it could be days." he said laughing. Derek could see that Lexie was bothered and something was off. "Hey, are you okay?" he asked, concerned.

"I'm fine." she lied.

"Lexie, you can talk to me. That's what post-it brother-in-laws are for." he said with his trademark McDreamy smile. "Come on, let's sit."

Derek led Lexie to the couch and sat with her.

"Okay, fess up." he told her.

"Well you know Mark..." she started.

"You mean my best friend? Why, yes, I do." Derek replied.

"Well, he proposed." Lexie continued.

"Yeah, Meredith told me. Congratulations, by the way. You must be so happy. Mark's a lucky man." Derek said.

"Yeah, but that's just it," she said, finally letting it out. "I don't know if I am ready for all of this stuff!"

"What stuff?" Derek asked, confused.

"THIS! The ring, the apron, the minivan in the driveway, the kids in the front yard. I am no wife, Derek. I am not even a real doctor, yet. I am still growing up and Mark...he is done. He already is the man that he is going to be for the rest of him life. I am still figuring myself out. What if the girl I turn out to be isn't what he's looking for?" Lexie asked, starting to break down.

"Lexie, you know that's not going to happen. Mark loves you, and that isn't something he does often. If he let you in then it proves that you are worth it to him." Derek said as her rubbed circles on her back, trying to soothe her.

"You don't know that. I am scared right now. I am scared that at some point Mark will realize he can do better and then I am gonna be left alone with this aching feeling in my gut again and I don't think I will make it through it next time." Lexie spilled.

"Don't." Derek said. "Don't give yourself reasons to walk away. If you are feeling this way, you have to talk to Mark. It is the only thing that will help you."

Lexie nodded.

"You are an exceptionally amazing girl, Lexie." Derek continued. "You are beautiful, intelligent, and you have one of the biggest and kindest hearts I have ever seen. You are truely one of a kind, Lexie, and if you give yourself the chance, I am sure you would be an amazing wife."

"You really mean that?" she asked.

"I do." he told her.

"Thank you." Lexie said as she got up.

"Anytime." he answered.

"Hey Derek" Lexie said, turning around "You're pretty amazing too, you know."

"You're gonna be fine, Grey." Derek smiled.

Lexie turned and made her way out the front door. She felt so much better about things with Mark. Who knew that all it took was a conversation with Derek, of all people, to set her straight again. She was finally starting to feel at ease and began to make her way home.

Lexie made her way through the front door and felt a rush of relief. She made her way to the bedroom and felt a sudden wave of dizziness. Weird. Maybe she just got a little vertigo, it happens right? It wasn't long before the nausea followed and Lexie was in the bathroom, hovering over the toilet, emptying her last meal. This was so not good. Not good at all. she thought to herself. Moments later she heard the front door.

"Lexie, I'm home." she heard Mark call out.

Lexie continued to sit on the bathroom floor, completely motionless. She had no energy and no will to move at this point. She just wanted to disappear.

"Lex?" Mark called again. He made his way through thr bedroom. "There you are." he said as he stood in the doorway.

"What's wrong? Why are you on the floor?" he asked, rushing to her side.

"I don't feel good." was all Lexie could get out before she was back to the toilet.

Mark held her hair back and rubbed her back as Lexie got sick.

"Did you eat something funny?" he asked, once she had regained her composure and leaned against the wall again.

"No. I don't think so." she replied. "I don't know what it is."

"Maybe you should see a doctor." Mark suggested.

"No, I'll be fine. I am just going to brush my teeth and get some sleep. I am sure it's nothing." she said.

"Okay, well I will join you." Mark said.

"You don't have to. I am fine." she told him.

"Lex, you don't feel good. I am going to lay down with you until you feel better." he insisted.

Lexie finished brushing her teeth and slowly made her way out to the bedroom. She found that if she moved slowly, the nausea didn't hit as hard. She crawled into her giant, soft bed and collapsed on her pillow. She felt an arm around her waist and she felt relief. It was in that moment that she realized that maybe this is exactly what she wanted and needed. That one person who could make her feel better at her absolute worst.

The next morning, Lexie woke to the smell of breakfast and the sudden need to revisit the bathroom again. She had thought this was a fluke, a 24-hour bug, but now, she was starting to get nervous. Maybe Mark was right, maybe she should see a doctor. She slowly made her way out of the bathroom to find Mark in the kitchen.

"Hey, there's my girl." he said with a grin. "Feeling better?"

"Not quite." she answered.

"Well I already made you an appointment with Dr. Scott." he told her. "I thought we would be better off safe then sorry. I know you said you were fine, but I don't want to risk it."

"Okay." Lexie answered. "I'll go."

Lexie arrived at Dr. Scott's for her appointment right on time. She made a habit of always being punctual, only this time she had kind of wished that she had decided to ditch or at least be late. She had no idea what she was walking into and part of her was scared to death. She filled out the proper paperwork and took a seat in the waiting room.

"Lexie Grey." the nurse called.

"Right here." she said as she got up and made her way to the back.

The nurse took jer vitals and led her to a room.

"Dr. Scott will be right in to see you. If you just put on this gown and have a seat on the exam table, he should be in shortly." the nurse told her as she handed her a light blue exam gown.

"Okay. Thank you so much." Lexie said as she took the gown.

Lexie got undressed and did as she was instructed. It felt like sje was waiting for an eternity before Dr. Scott finally made an appearance.

"Good afternoon, Ms. Grey. What seems to be the problem, today?"

"I have been having problems with nausea and dizziness." she replied.

"When did this start?" he asked.

"Yesterday. I thought it might be some kind of flu bug or something."

"Well let's get some blood and let's get a urine sample and we will see what's going on with you today, okay?" Dr. Scott said.

2 hours later

"Ms. Grey, we got your lab work back and I think we may have found the cause of your nausea and vertigo." he informed her. "Congratulations, you are pregnant."

"I'm- I'm sorry. Can you repeat that please?" Lexie seemed lost.

"Ms. Grey, you are pregnant. Congratulations." he said again.

"What?" she exclaimed. "No, that can't be right. I was using the pill. There is no way that-"

"The pill is not always 100% effective." he told her. "Well, here is your paperwork and I took the liberty of setting up an appointment with Dr. Morgan, our OB-GYN for next week. Thanks for coming in."

The doctor left the room and left Lexie completely flabbergasted. What was she going to do? Clearly, she had to tell Mark. What if he freaked out? It's not like she could really blame him. She was freaking out on the inside as well. She continued to be consumed by these thoughts as she made her way through the front door of her apartment.

"Hey, you're home." she said when she saw Mark.

"Yep, early day." he replied. "How did your appointment go?"

Lexie felt butterflies in the pit of her stomach. This was it. Do or die.

"Can we sit?" Lexie asked.

"Is everything okay?" he asked as they sat down on the couch.

"They ran some tests and they found out why I have been feeling so funky." Lexie began "It turns out that-"

"Lexie, spit it out." Mark urged.

"I'm pregnant." she said.

"What?" Mark asked, surprised.

"Pregnant. Knocked up. With child." Lexie said.

"No, I-I get it. I'm just surprised." he said.

"We can figure it out though, I mean, if you're not ready or this isn't what you want." she said.

"Are you kidding me? Of course, I want this. I am so happy, Lexie. Come here." Mark said as he pulled her close to him.

"I love you so much and I can't tell you how happy it makes me to hear that we are going to be parents." he told her before moving to her belly. "Hey there, little one. This is your daddy. I love you."

Lexie couldn't help but smile and think that maybe everything was starting to work itself out. She was finally happy and she hoped that things would stay like this.
