AN: This is my first Grey's Anatomy fanfic, but I've been written a couple of short bits for different characters and I thought it was about time I shared some. This is from when Lexi and the other interns start, but it's sort of AU and OOC, as some relationships etc. are very different and storylines don't follow on from in the show, but I hope you enjoy it anyway.

Lexi was standing alone outside the tall building that stood in front of her, and she looked up in awe at the place she would be working for the next few years. She took a deep breath and pushed the door open, taking in the chaos around her. She smiled to herself and followed the other interns she recognised dashing in the other direction. This should be fine, she told herself, just try and make friends and whatever you do, don't mention the baby.

She stood watching all the babies in day care, wanting more than anything to see her baby Dylan. She shook her head to break out of this trance. No, don't think like that, he's happy and probably isn't missing you at all, and anyhow, this is a great job opportunity, don't mess it up.

Suddenly, a firm hand on her shoulder jolted her from her thoughts and she turned to see a handsome, dark haired man looking right at her. She couldn't help but stare straight into his dreamy blue eyes. Then she noticed the expectant look on his chiselled face. Crap. He'd said something.

"Um… sorry, w-what was that s-sir?"

She mumbled, kicking herself at how stutter she sounded. A large smile crossed his face and lit up his eyes, and he let out a soft chuckle.

"I said, you must be one of the new interns. Are you lost?"

"Oh, um, no. Well yes….. Yes to the first bit, but no I'm not lost. I was just – juts going now sir." Lexi replied hastily, stumbling over her words.

The mysterious man in front of her chuckled once again.

"Ok-" He paused slightly, leaning closer to read her badge "- Dr Grey… but please stop calling me Sir, its Dr Shepard. Dr Derek Shepard."

Once again he flashed his heart breaking smile, then turned and left the room.

Lexi could do nothing but stare at the space where Dr Derek Shepard had just been, her mouth still hanging slightly open.

When she had left day care, she made her way down to the patient's room she had just been paged to. When she got there, she saw the face of the mysterious Dr Shepard she'd just encountered, and another man who was horrifyingly familiar. She didn't know his name – she hadn't bothered asking – and she'd been too drunk to care at the time. When he saw her, she noticed all the colour drain from his face. To him, she was just the woman he had taken advantage of – and apparently cheated on his wife on – 2 years ago, he had no idea about the baby. Therefore, she couldn't help but smile slightly seeing the affect she had on him now.

"What's up Karev? Look as if you've seen a ghost?"

A voice called from behind her, she turned to see a pretty doctor with a small, teasing smile on her face.

"Hey, I'm Meredith Grey, second year resident." She held out her hand to Lexi to shake. "And you are?"

But Lexi couldn't get the words out, couldn't even bring her herself to shake the hand in front of her. She felt the blood rush to her cheeks, and her sense came back to her. She quickly reached out and shook Meredith's hand, hoping she hadn't noticed the stalling.

"Oh, um, hi, I'm Lexi" She forced out, before turning away to face Derek who was just about the start.

She couldn't believe it, not only did the father of her child work her, but also the half-sister she'd never met and didn't even know existed until a month ago (and who didn't appear to know she existed)

AN: I know this is only short, but it's just sort of setting up the story, I've already started on the next chapter, so hopefully it'll be up soon. Thanks for reading!
