I don't own Grey's Anatomy!

Chapter Four

"Is it just me, or is Lexie Grey acting odd..." Callie muttered to Mark as he walked over to her. "I know you said something before, but now I'm seeing it. Especially the other day after she ran out of the room looking like she was gonna hurl."

Mark bit his lip as he looked up at Torres. "She kind of did..."

"Oh god." Callie's face scrunched up. "Well she came back to check on Emma, who is getting a lot better might I add."

"That's good. That kid is adorable," Mark said, sighing as he signed off his papers. "You know, seeing Emma it makes me wonder…"

"About?"

"It's just...Sometimes I kind of wish I did stay in Sloan's life but at the same time part of me doesn't want to change how my life went," Mark said woefully as he tapped the end of the pen against the counter.

"Well I wouldn't want you to change anything either because, well then we probably wouldn't have met," Callie teased him, winking. Mark chuckled as Callie began to through some of the paperwork in her binder. "Plus you might've not met Lexie."

"Oh shut up, Torres," Mark responded scowling. Callie just chuckled as she gave him a playful nudge.

"Well I'm going to check back on Emma," Callie announced, closing her binder. Besides Lexie and Mark, Callie Torres has formed an instant attachment to Emma Vargas. Her and Arizona were watching the little girl carefully now even though Mark and Lexie would sometimes stop by to check on her. "I got her this for her in the gift shop," Callie whispered to him, showing off a brown stuff bear. "I wanted to cheer her up because of her parents."

"They really aren't doing too well, are they?" Mark asked, getting a soft nod from Callie. It's been a two days since they came in to the E.R. The drunk driver died on the table while his wife was still alive, but she was currently in a coma. Meanwhile Danny Vargas was still in critical condition and under high observation. His wife, Diana Vargas, seemed to have improved, but the tear she had in her heart wasn't looking too good. Seattle Grace Mercy West was doing everything in their power right now to help them.

"Mark, I don't know if they're going to make it. Her mother might, but her father is in critical condition. I need them to make it because that little girl needs her family," Callie said sternly, looking towards Arizona who was in Emma's room now.

"Wow, you really like this little girl?" Mark observed, a small smile playing on his lips.

"Well, I stayed with her again last night. When I first met her, after wrapping her up with Little Grey, she seemed very scared. Once I sent Lexie home for the night, I just stayed with her. Talked with her until she went to sleep with Arizona and I don't know...We just stayed there. No kid should be left alone like that," Callie said, sighing. "Make me want kids even more."

"You should try to adopt, it would be a good thing or even get a fertility treatment done. I'm sure Addie or Naomi would do it for you with no problem," Mark suggested.

"Yeah, but I need to talk about it with Arizona first," Callie replied uncertainly as she looked down at the bear.

"Well whatever you do, you would be a great mother, Torres," Mark said, chuckling as he gave her a side hug. "Now go check on Emma. I'll find out more about her parents. Hopefully one of them will be well enough to see her."

"I hope so too," Callie responded, backing away towards Emma's room. Mark chuckled before going back to charts. He then heard a light laughter and cocked his head to see Lexie walking in with Alex Karev and Jackson Avery. She was laughing with the two of them at something.

He just sighed, forcing himself to turn away. Mark just needed to walk away. He needed to.

"So, when do you plan to tell Sloan?" Alex asked as he and Lexie hung around by the locker room to get their assignments for the day. Jackson went off to go find April leaving them alone. "It's going to be almost been a week since your appointment. You need to tell him..."

"I know, I've just been wrapped up with a case," Lexie muttered, rubbing her stomach. She was in a pretty nasty mood today. The highlight of her morning so far was throwing up her breakfast and then crying for almost ten minutes after she accidentally spilled the orange juice on the counter. Then there was the lack of sleep and the fact everything she does lately has gone to shit. Now she had Alex Karev acting like a moral compass. "I'm kinda tired today, that's all."

"Are you sure you're up for work, Lex. You seem a little pale," Alex observed, placing the back of his hand against her forehead.

"I'm fine. I didn't get any sleep last night, that's all," Lexie said, yawning as she swatted his hand away from her forehead.

"You got to be careful though. You're not just watching out for your self now, you're watching out for the your little cargo," Alex pointed out to her, tapping her stomach with his finger.

"Don't call the baby little cargo," Lexie groaned, rolling her eyes. "And I'm fine. Trust me, I'm fine. I'm sick of people asking me if I'm fine."

"Okay, shesh," Alex said, putting his hands up in defense. "Just take it easy, alright."

"Yeah, yeah," Lexie mumbled, placing her chin in her hands as she leaned against the counter. Her body was all achey today and she felt like she was sick. It was probably from her exhaustion and the fact that she was pregnant.

Lexie looked at her chart to see she was checking up on Mr. and Mrs. Vargas. Before she went to Mrs. Vargas's room, Lexie peaked her head in Emma's room to check on her. Lexie watched as she just woke up but was chit chatting away with Callie. The two formed a pretty instant bond and it's caused Callie and Arizona to watch out for her since she was emitted into the hospital. Lexie was happy to see Emma was awake and well, but now it was time to check on her mother.

Diana Vargas had a punctured rib, a couple of broken bones, and a big tear in her heart. She just woke up last night and seemed to be doing a little bit better today.

"Hi, Mrs. Vargas. I'm Dr. Grey, I'm your Doctor today," Lexie introduced herself to the women. "I'm just going to check how you're doing."

"Oh I feel a lot better," the woman replied, her voice a bit raspy though. "How's my Emma? Or my Danny?"

"Emma is absolutely fine and Danny is still unconscious, but he's improving," Lexie told her as she got her stethoscope out, placing it on the woman's chest. "How are you feeling today?"

"I'm feeling a little better," Diana confessed to her. "Just sore, that's all."

"Well that should be normal, you did get into a pretty huge car crash," Lexie told her, checking out her vitals.

"Hey there." Lexie froze when she heard the familiar voice. She snapped around to see Mark standing behind her. "I was just wondering how Mrs. Vargas was doing. Emma's pretty worried about you."

"Oh, my poor baby. I hope she knows I'm alright. I'm glad she made it out okay," Diana said, sighing in relief as she leaned back against the pillows.

"She was a very good patient. Dr. Grey and I treated her when she came in to the E.R. Emma's a very brave little girl," Mark said, giving Diana a warm smile.

"Good. She must be worri-" Diana Vargas was then cut off, her position frozen as she looked down at her bed.

"Mrs. Vargas?" Lexie questioned, looking down at her to figure out what was wrong. She gently approached the women but out of nowhere Diana's body seemed to collapse. Lexie's eyes darted to the machines which were now beeping out of control.

"Code blue!" Lexie yelled out as Mark and a few nurses ran to her side. "It's a code blue!" She turned Diana on her side to check for any signs of a pulse or breathing. Of course, it was very faint and almost non existent. Lexie gritted her teeth as she began compressions while the nurses came in with paddles.

"Clear," Lexie called out as they charged the paddles. They shocked Diana, but still nothing. Lexie kept upping the charges, but nothing seemed to be working.

"Lex, Lexie you need to stop," Mark told her, touching Lexie's arm gently as she tried to up the paddles up one more charge. "It's been almost twenty minutes…"

"No. No, I can't stop," Lexie snapped at him, beginning to start chest compressions. "This little girl can't lose her mother. She can't be without her mom. She needs her mom!"

"Lexie!" Mark yelled, causing her to freeze all together. He sighed, pulling her away gently from the now dead body of Diana Vargas. "She's gone. Someone call it."

Lexie trembled as she looked at her watch, "Time of death. 10:30 am." She then stormed out of the room, not looking back. She felt a lump rise in her throat. Lexie tried to shove it down her throat, the sobs, but she couldn't. Emma doesn't have a mother. That sweet baby girl doesn't have a mother. How could something like this happen? Why do things like this happen? What if her baby lost her? Lexie felt sick to her stomach even thinking about that.

"Lexie! Lexie! Wait up!" Mark called out, running down the hallway after her. He kept running until he finally caught up to her, placing a hand on her shoulder to stop her from progressing over to the elevator. "Are you okay?"

"No, she's dead. Emma doesn't have a mother!" Lexie cried out, letting the tears stream from her eyes. "Why...Why does life work this way? Why?!"

"It just does, Lex," Mark said, touching her shoulder gently. "Are you sure you're okay?"

"What's that suppose to mean?" Lexie questioned, dapping her eyes with her sleeve.

"What it means is, I know something's up," He said, making sure she didn't leave his side. "You aren't acting like yourself."

"Maybe I've changed Mark!" Lexie cried out desperately. "Maybe things are changing! I'm not the same Lexie you know!"

"Lex, what...Look, is there something you need to tell me?" He asked, his tone was pretty much begging for an answer. "I know, I know there's something up. You can deny it all you want Little Grey, but I know when there's something going on with you."

"Look, Mark...I need to tell you something but I just-" Lexie then got cut off as a bunch of nurses and doctors ran to the room right next to Mrs. Vargas's room.

It was her husband, Danny Vargas.

Lexie felt her heart drop as the nurses ran in there. "What's going on?" Mark demanded, being the first doctor in there as him and Lexie dashed in.

"I don't know. I was walking past the room and the machines went all crazy. He's coding!" a nurse informed them.

"Mark..." Lexie's voice was now wobbly as she watched Bailey run in there too to preform CPR with Mark.

"What Lexie?" Mark barked, only because he was concentrated on Danny Vargas. He needed Emma to at least have one parent alive. "Whatever you needed to tell me, it has to wait for a second."

"I don't think it can," Lexie responded, gripping to the doorway. She felt lightheaded as she stumbled. Lexie's heart was pounding out of her chest and it was becoming hard to breathe. The room was spinning before her now and she couldn't seem to control where they were moving to next. "I'm...I'm-"

"Grey? What are you doing?" Bailey questioned, noticing Lexie was stumbling in the doorway.

Suddenly the world is black for Lexie Grey as her eyes roll back. Her body going limp, causing her head to hit the doorway in the process.

"Lexie!" Mark yelled, running to her right before her body could collapse to the ground. He was now holding her in his arms bridal style. Lexie's arms were dangling out of his arms as he tried to hold her tightly to him. "Lexie! What's the matter with her!?"

"Get her out of here! And page another doctor!" Bailey yelled at him as she continued CPR. Mark sighed, heading out of the room, trying to get help. He looked back at Lexie who looked even paler than before.

"Shit!" Mark looked up to see Alex Karev starring at him from down at hall. His eyes were now wide as he then began to run towards them. "I told her this morning to take it easy, but does she listen to me? No! No one listens to me," He muttered to himself as he approached the two.

"Karev, what's going on?" Mark asked, holding tightly to Lexie. "Is there something wrong with her?"

"I don't know if I should be the one telling you know," Alex muttered, scratching the back of his head. "But let's just get her into a room. Now."

Derek grinned as he watched Meredith from afar fill out some labs. She peaked up, sensing that he was looking and grinned. Slowly she approached him and let his arms wrap around her waist. "So, I was thinking maybe tonight we go out for dinner. The kids seem pretty busy tonight," Derek said, chuckling as he referred the fact Lexie and Alex would be on call tonight. Meredith chuckled as well before planting a kiss on his lips.

"Yeah, that sounds great. I just want to make sure Lexie gets home safely though and at one point discuss with her about cutting her hours short," Meredith told him, playing with a button on his shirt. "Is it weird..."

"What's weird?" He questioned, cupping her face in his hands.

"Is it weird...I just feel a lot more protective of Lexie since she got pregnant." Meredith sighed. "I mean, I just didn't know how to do it at first, be her sister and all, but now she could be in trouble and it scares me. It scares me and it makes me angry at the same time that someone like her, who had a wonderful family life growing up, is abandoned by everyone. Her mom's dead, Thatcher's been an ass since he took up drinking, and Molly, who I don't know her well, is halfway across the country."

"You want to protect your family," Derek remarked, giving Meredith a sweet smile that had her rolling her eyes.

"Okay, let's just drop it," Meredith replied, playfully nudging him.

"You have grown so much, I'm proud of you," Derek told her, chuckling as he kissed her forehead.

"Really?" she laughed as he then threw an arm around her shoulder.

"You know, I was thinking we could use a quick break," Derek whispered to her, winking at her. Meredith grinned mischievously as grabbed his hand.

"Lead the way, Dr. Shepherd." The two laughed as they headed straight to the on-call room. They didn't get to make it because just as they were about to enter they saw Mark rushing out of the elevator with Alex Karev right behind him. In his arms was a girl.

It took a better look, but when Meredith realized who it was she felt her stomach drop. "Lexie!" She cried out, rushing over to the two guys with Derek right behind her. "What happened!?" Meredith demanded, trying to check on her sister.

"She fainted!" Mark told them fiercely. Derek noticed how Mark held the younger Grey sister in his arms. Her head was resting against his chest while he held onto her so tightly, making it seem she was trying to leave him. "Something's wrong with her!"

"Alright, just calm down Mark," Derek said, touching his arm gently. "Let's go get her check out. Meredith, you know who to page."

"On it," Meredith said, quickly taking out her pager and paging a 911 to an OB.

They brought Lexie down to the E.R where she was rushed to a room to be checked out.

"What's wrong with Grey?" Owen asked as came into the room to check on Lexie. Mark finally was able to let her down, lying her gently on the bed, but he didn't go anywhere. His hand held tightly holding her hand.

"I think I know what's wrong with her, but I don't think it's anything you boneheads can fix," Alex muttered, leaning against the doorway. "Just wait for the um doctor Meredith paged."

"Why can't you just say what's wrong with her!" Mark yelled at him. "She just fainted, in my arms. I'm not taking it lightly!"

"Well I can't tell you because well, it's not my place!" Alex responded keeping his ground, but right now he was feeling himself shrink a bit inside. Alex did not want to be the one to tell Mark Sloan that he could be Lexie's baby daddy. He was pretty sure Lexie, Meredith and Derek would kill him before he had the chance.

"Why can't you tell me!?" Mark was clearly getting agitated as he stood up, ready to get into Alex's face.

"Woah there guys," Owen said, stepping in the middle between the two men that were ready to fight it out.

"Mark!" Derek yelled, causing them to all look at him. "You need to calm down. It isn't Alex's place and neither is it mine. It was suppose to be Lexie's, but..."

"But now what?" Mark asked, growling as he then looked back at Lexie. "I know something is up with her Derek. I know you think I probably don't care about her, but that's a lie. A stupid lie because I care a lot about her still, okay! I know when there's something wrong with her!"

"Here, I brought Dr. Fields," Meredith muttered, walking in with a blonde lady right behind her.

"What do we got?" She asked, checking Lexie's vitals.

"Why is she here..." Owen trailed off, eyeing the others. "Is she-"

"Is she what?" Mark questioned, looking all around the room frantically.

"Why is someone from OB here?" Owen asked, causing the room to go silent. Mark's eyes widened as he looked at the doctor.

"Ooo, let me guess someone didn't know she was pregnant," Lucy murmured, looking around awkwardly before exchanging looks with Alex.

"You can say that..." Alex trailed off nervously.

"She's a twenty-six year old female, about five weeks pregnant now, and she just fainted," Meredith said to Lucy through the awkwardness of the silence.

"Alright, thank you," Lucy muttered, setting her equipment up as her and Alex checked on Lexie and the baby.

Mark looked down at Lexie in the bed. Looking at her, his whole world felt like it was spinning. His heart was racing and he couldn't seem to function as he looked at Little Grey. The same woman who broke up with him before she didn't want to start a family just yet. "She's pregnant." Mark felt the words leave his mouth slowly, his eyes frozen on her unconscious form.

"Sloan, wait-"

"No, I'm fine," he snapped, stepping away from Lexie's bed. "Have a nice life with her, Karev!"

Without the others being able to explain anything to him, Mark Sloan stormed out of the hospital room.

"Mark! You have it all wrong!" Meredith tried to yell at him, the others calling out to get his attention. But he didn't hear them as he ignored their protests and ran as far away as he could. All he could think was, the woman he loved was going to have the baby of Dr. Doucheface.

A/N: Soooooo Mark knows about Lexie's pregnancy! And now I'm gonna leave it off on that cliffy lol ;) In the meantime, thank you for reading, please review, and be on the lookout for the next chapter! :D
