A/N: Okay so I just wanted to maybe try something out. So I've been watching Grey's and let me just say, Lexie and Mark are my favorites and I don't like how their relationship went downhill like that in season 6. So, I'm going to take matters into my own hands and try this AU. Let's say this is how I wish things could've maybe gone. It's going to take place sometime after 06x14 'Valentine's Day Massacre.' It's going to mostly be Slexie, but there'll be a little Merder and some Mark/Callie brotp love. Anyway, I hope you enjoy!

Chapter One

Lexie Grey groaned as she finished her last rounds of the day. She was extremely tired. After spending twenty-four hours in the E.R, she wanted to just sleep. It all felt like a blur to her today. Injured person after injured person...She just wanted to sleep it all off. That's all she wanted. Sleep. It's bad enough she had to deal with the aftermath of breaking up with Mark, she also had this whole mess going on with Alex. Her whole life was a big fat blurry mess.

"Hey Lex, were you in here all night?" Meredith asked, noticing her sister was sitting behind the desk half asleep with her face in her hands.

Lexie looked up to see Meredith standing over her with Derek by her side. The two had their hands intwined together as they looked down at the resident. Lexie smiled sadly at them. She felt a tightness in her chest seeing their closeness.

"I'm okay, just exhausted. That's all," Lexie replied, sighing as she leant her cheek against the palm of her hand. "Plus I've just been a little um…Under the weather."

"You do look a little pale," Meredith observed, taking a better look at her sister. "You should really come home."

"Probably just need some sleep. It's been a long day at the E.R," Derek chimed in, referring to the fact they had all those patients from the collapsed restaurant. He then waved his hand towards him and Meredith. "Come on, we'll drive you home."

"Okay, sure. My shift ends now. Just give me a few minutes and I'll be there. I just need to go get my stuff and change out of my scrubs," Lexie announced, standing up and giving them a tired smile. "I'll meet you two at the car."

"Okay, see you in there," Meredith replied, walking away hand and hand with Derek.

"Does Lexie seem a little off to you?" Derek asked his post-it wife as walked into the parking lot. There was a light drizzle hitting the as two swung their intwined hands back and forth."She's been acting a little…Odd? I guess that's the word, lately."

"She just broke up with Sloan, that's probably why. It's hard to recover from something like that," Meredith replied, sighing a bit. "I think she really loved him."

"True. Mark hasn't been the same since Lexie left and now with Sloan gone, it's been a bit harsh. He's grown up a bit for his daughter, but Lexie had a really good affect on him," Derek said, sighing as he thought of his best friend and sister in law. "Things'll work out though in the end."

"I guess. Just have to wait and see what'll happen," Meredith said, leaning over to kiss Derek on the lips. The two smiled as they then headed into their car to wait for Lexie.

Meanwhile Lexie was rushing down the hallway, quickly and as quietly as she could. She headed straight to the locker room where Alex was waiting for her. He looked really nervous as he then shoved a paper bag into her hands.

"Thanks," she whispered, putting it into her purse. "I'm going to check them tonight and I'll tell you in the morning. Alright?"

"Okay. Just..." Alex struggled with his words as Lexie began to get ready to head home. "Look, Lex...I'm not going to abandon you. If...If it's mine I'll be there for you and even if it's not, I'll help you out too. You know I'm not a bad guy. I'm not like that, you know? I won't make you go through this alone. Whatever you chose to do, I'll support it. Just know I won't be your enemy."

"I know," Lexie whispered, her lips forming into a sad smile. "I know Alex, just don't get your hopes set too high. You might not even-"

"I know," he cut her off, repeating almost the same answer she gave him. Alex gave her a small smile before she darted off, rushing down the hall to get home with Meredith and Derek. Lexie was nervous, all sorts of butterflies flying in her stomach. She needed to know and fast.

Running down the hall, Lexie didn't notice but she whacked head on into the broad chest. When she looked up to see who it was, it was none other than McSteamy himself. When Lexie's eyes locked with the icy blue ones staring back at her, she cringed. Her cheeks burned and she could tell she was blushing a bright red. "Sorry, Dr. Sloan."

"It's fine, Dr. Grey. Just watch where you're going next time," He replied, his tone icy. Lexie nodded meekly, feeling her nerves taking over.

"I was just...I'm just going home now that's all. Meredith and Derek are waiting in the car and...Yeah," She stuttered, looking down at her feet. She didn't know why she needed to explain this to Mark, but it slipped out. Maybe it was the nerves.

"Are you alright Grey?" He asked, noticing the slight paleness of her face.

Mark Sloan wasn't taking this whole break up with Little Grey very easy. He was angry with her, but at the same time he missed her...A lot. He loved Sloan and his grandson so much, but the small selfish ugly part of him wished that she never came to Seattle Grace for him. Now they were both gone since Sloan left as well and he had no one. He lost his family. Mark was frustrated. He wished Lexie understood in the beginning what this meant to him and this whole thing wouldn't be a mess right now. He wished that instead of abandoning him and sleeping with freaking Karev...She could've stayed. Lexie could've became a family with him, Sloan, and the baby. But no, Lexie wasn't ready…Then again, she was only twenty-five and his daughter was closer in age to Lexie than Mark was. Maybe it's the fact they're from completely different worlds, but Mark still loved her. There was no doubt about it that Mark Sloan still felt a pang of sadness every time he saw her walk down the hall.

"I'm fine," Lexie stammered, gripping tighter to her purse. "Just had a rough night, that's all...I'll see you tomorrow, Dr. Sloan," She replied civilly before rushing down the hall way again.

"Wait, Grey-" Mark blurted out, not wanting her to go just yet.

"What?" Lexie asked, spinning around so she was facing him in the eyes again.

Mark tried to speak, but the words slipped off his tongue. He sighed and just shoved his hands into his pockets, "Nothing."

Lexie just huffed and walked out the doors of Seattle Grace Mercy West Hospital. Seeing Mark, it took a bit of a toll on her. She could feel tears welding up in her eyes and a lump in her throat. Lexie didn't want to admit it, but she missed him. Alex's been nice, but he missed Izzie. To be quite honest, they were just one another's rebound.

Lexie just shoved her feeling aside as she then headed into Meredith and Derek's car. She had bigger things to worry about. She was happy they didn't seem to notice her nerves in the car as they talked normally with one another. They did include Lexie in the conversation as well, but they seemed very wrapped up in each other for the most part. Talking about their day and all. Derek and Meredith were so in love and it made Lexie feel bittersweet.

As they rode home the radio softly played in the background. Lexie toned the music playing for a bit, but just as they drove away from the hospital the soft tune of Poison's Every Rose Has it's Thorn started to play. When Lexie heard that tune she felt her chest tighten up. She smiled though, remembering how things use to be.

"I use to love the Backstreet boys," Lexie said, chuckling as she turned up the radio when she heard the old tune. "When I was younger, my best friend use to be obsessed with them. I went to a concert with her in 1999 and they weren't half bad. They were my first concert."

"I hated the Backstreet Boys. I prefer some good classic rock n' roll. Plus when this song came out I was thirty-one and as great as those times were, the Backstreet boys were the last thing on my mind," Mark told her as he then changed the station to one that was now blasting some Led Zeppelin.

"Sometimes I forget we grew up in different eras," Lexie said, her tone teasing. "I was in diapers while you were probably 'shaking your grove thing' at your junior prom."

"Hey, Little Grey, I'm not that old. Don't make me older than I already am," He said, his eyes showing signs of playfulness. "Anyway we didn't 'shake our grove things' back in the eighties. This was a different time of big hair and very loud, bright clothing. Don't you remember, you were born in the eighties."

"Yeah...1984. I was five in 1989. Don't remember a lot," Lexie said, shrugging.

"So that means while you were starting kindergarten I was in college." Mark breathed. The two sat in a few moments of awkward silence. It didn't last long because all of a sudden the Poison song started to play. Lexie Grey brightened up immediately and turned it up.

"Hey, I remember this song when it came out. It was around the time of Molly's second birthday. The end of 1988 I believe...Molly use to love this song so much." Lexie laughed at the thought, causing their subtle doubts about their age difference to settle down. Mark let a small smile cross his face as she spoke. "My mom even took pictures of us on this old little camera she use to have and we were sitting in the back seat of the car jamming out to it..." Lexie trailed off as a memory of her mother hit her. She missed Susan.

"Hey." Lexie looked up to see Mark smiling down at her. He seemed to notice her distress talking about her mother. He piped up, "I use to love this song too. Derek's sisters use to sing it all the time and I remember it playing this one time Derek and I went to this really awesome party."

"Looks like we do have something to share from similar eras," Lexie said, grinning proudly to herself.

"Well hey, age is just a number. What we have...It's something else," Mark told her, a classic Sloan grin gracing his face. Lexie chuckled as he parked the car in front of their apartment building. The two then leaned over in their seats, kissing each other gently yet passionately.

"I love you," She murmured against his lips as his fingers ran through her hair.

"I love you too," Mark replied, kissing her again. The two didn't take long but soon they were rushing upstairs to the warmth of their bed.

Lexie sighed to herself. She remembered it all so well and how after she just spent the night lying in Mark's arms. She remembers the way it felt, how his arms wrapped tightly around her. How warm he was and the sound of his breathing. The way her head fit perfectly in the crook of his neck and the way it just seemed so perfect. Like something out of a dream. She felt like some sort of puzzle was completed with him around. She missed that feeling, that wholeness.

When they got home, Lexie ran straight into the bathroom. Meredith and Derek were too busy 'romancing the stone' to get out of bed so Lexie had an easy chance to do this without suspicion.

They were suppose to be a few quick moments, but they felt like hours. She felt so anxious, trying to hold it together. Her nerves bouncing all over the place. Soon the timer went off on her phone and Lexie Grey approached the three sticks slowly.

Each one had the stupid pink plus sign.

They were all positive. Lexie Grey was going to have a baby and she didn't even know who the father was. Her life was truly a big fat blurry mess.

A/N: Soo? Tell me what you think about it and let's see how I'll continue this. Thanks for reading and please review :D
