Author's Notes: I am slightly obsessed with cheesy holiday romance movies and once I started thinking about what sort of shenanigans Mark and Lexie could get into in a cheesy holiday romance...I couldn't help myself. Hope that you enjoy! Happy holidays!

Lexie sighed as she finally got her bag in the overhead department and slid into her seat. It was a bit of a madhouse trying to get to the airport on time from Lizzy's apartment, but she made it. And now all she had to do was attempt to relax and get through the next six hours on the plane. She pulled out her phone to text Lizzy one last time when she noticed someone standing next to her and reaching up to stow their bag. She glanced up and was struck speechless.

The most beautiful man she'd ever seen was standing next to her, smiling down at her. "I'm your traveling companion today," he said with a grin that Lexie was positive got this man whatever he wanted.

"Oh! Great!" She stood quickly, too quickly, and he wasn't quite expecting her to move so fast. She bumped into him before he had a chance to step back and he caught her shoulders in an attempt to balance himself. "Oh my gosh, I'm so sorry."

"I'm used to beautiful women throwing themselves at me," he said with a wink, before moving into the window seat.

Lexie rolled her eyes, scoffing as she sat back down. "Yeah I'm sure with those blue eyes and that smile, women just can't help themselves."

"They can't! I'm irresistible."

"And humble." He chuckled and nodded as Lexie grinned at him. "So, do you have a name, Mr. Irresistible? If we're going to be seat buddies for the next six hours, I think I should know your name."

"Mark Sloan."

He stuck out his hand and Lexie took it immediately, shaking it firmly. "Lexie Grey."

"It's sure to be a pleasure flying the friendly skies with you, Lexie."

Lexie laughed. "You certainly are a charmer, aren't you, Mark?"

He held up his hands. "Guilty as charged."

"What do you do for a living? Actor? Lawyer? Male underwear model?" Lexie asked, a sparkle in her eye.

Mark laughed and shook his head. "Thanks for that last one. None of the above. I'm a doctor."

Lexie raised a skeptical eyebrow. "A doctor, huh? Of what?" She couldn't count how many times a guy had tried to pull the doctor card on her, only to have a doctorate in philosophy. Although Mark Sloan did not look like any philosopher she'd ever met.

"Double board-certified surgeon in plastics and otolaryngology." That shit-eating grin was back.

Lexie's jaw dropped. "Oh wow, you really are a doctor." Suddenly her eyes went a bit unfocused and then widened. She practically squealed and grabbed his arm that was resting on the seat rest between them. "Wait a minute! Dr. Mark Sloan! New York Pres! You did that almost full facial transplant a few years ago! 22 hours! 3 years of planning! The nerve work alone…oh my god!"

It was Mark's turn to be surprised. "You some sort of surgery groupie there, Lexie?"

She laughed. "Something like that. I'm a surgeon too. Fifth year resident at Mass Gen."

Mark let out a low whistle. "Mass Gen? You must be pretty good."

Lexie smirked, tilting her head playfully. "I am."

"If you're a resident at Mass Gen, how come you were in New York? And now you're on a fight to Seattle?"

"I was here visiting my old college roommate. She's an actress and she was in an off-off-off Broadway play. And now I'm on my way to Seattle to see my sister. I'm spending Christmas with her. What about you? What's dragging you away from Manhattan?"

"My best friend guilted me into visiting him. Said he couldn't stand the thought of me spending Christmas alone again and insisted that I come out and visit him and his wife and their kids."

Lexie smiled. "Everyone should have someone to guilt them into not spending the holidays alone," she teased. "How long are you going to be in Seattle?"

"Just until the day after Christmas. You?"

"Same. But I don't have a shift until the 28th, so that's nice. I'll have a few days back in Boston to run errands and stuff. And just decompress from spending the holidays with my little niece and nephew. They're adorable, but my niece has so much energy. Luckily my nephew is just a snuggly little baby still, but…still a lot."

"Sounds like my friend's kids. I feel like every time I talk to him, he's being interrupted by one of the kids. His wife sent me a picture of him the other day having a tea party with his daughter." Mark chuckled. "He has four sisters, so I think he's pretty used to it."

"Four sisters! Wow. That must have been…a very loud house."

Mark laughed. "Oh, it was. But it was the best. I used to go over there as often as possible. I grew up with Derek and his family…they're basically my family."

Lexie smiled. "That's really sweet. I bet that he's really excited that you're coming out to visit."

He nodded. "Yeah, I think he is. And I wouldn't tell him, but I'm glad he asked me. The plastic surgeon, bachelor lifestyle is extravagant, but it can get tiresome sometimes."

Lexie rolled her eyes and Mark grinned at her. "Oh, you poor thing. I'm sure that the Manhattan social scene is just exhausting for you."

Mark's grin turned to a smirk. "You have no idea."

Lexie laughed and shook her head. "How long have you been a slave to the Manhattan social scene, Mark?"

He shrugged, spreading his hands slightly and leaning back, as best as he could, in his seat. "All my life. Born and bred New Yorker."

"Oh wow, really? I love Manhattan, but I don't know if I could actually live there. I grew up in a suburb right outside of Seattle. I always thought Seattle was a big city, until I went to Manhattan for the first time."

Mark grinned. "It's the best city in the world."

They spent the next six hours chatting, the conversation never running dry. Lexie picked his brain about all sorts of surgeries and before his ego got too out of control, she confessed that she had a photographic memory, so she remembered basically everything she'd ever read. She'd had an interest in plastics before really committing to neuro, so she had read quite a bit about some of his surgeries. And then after he learned about her photographic memory, he spent time quizzing her on things, determined to see if her skill had a limit.

He still hadn't discovered one by the time that they landed. Lexie sighed and smiled, leaning back in her seat slightly. Mark quirked an eyebrow at her and Lexie turned her head towards him, grinning. "I actually hate flying. I usually get so nervous…" Her smiled brightened as she looked at him. "So thank you. You distracted me enough that I didn't even once picture my horrible death as the plane went down in a ball of flames."

Mark's brow furrowed and he tilted his head in concern. "That's…intense."

Lexie shrugged. "You should have picked up on that fact some time in the last six hours."

They made their way out into the terminal and waited around for their bags. Mark grabbed both his and Lexie's from the carousel and they smiled at each other.

"Well," Lexie said, awkwardly tucking her hair behind her ears. "Thanks for keeping me entertained throughout the flight. Although, I was planning on getting some sleep." She laughed. "I survived my intern year and everything but when they say that New York is the city that never sleeps, they mean it!"

Mark chuckled. "Sorry. Or you're welcome?" He paused, before smiling at her. "What direction is your sister's place? We could…share a cab, if you wanted to. With Christmas shopping and just having a trip to New York on a resident's salary…I'm sure you could save some money if we're heading in the same direction."

Lexie immediately beamed at him. "Yeah! Yeah, I'd love to. She lives north of here."

"Great! So does Derek. We can just split the cab fare."

Lexie nodded. "That sounds great!"

They walked outside to the cab lane and waited patiently with all the other weary travelers, although they looked far more energetic than anyone around them as they kept talking and smiling at each other. When they got to the front of the line, the cabbie grabbed their bags and Mark and Lexie slid into the back of the cab.

"So where am I dropping you two off?"

"Two different locations, but they should be on the way," Mark said, digging around in his pocket for the slip of paper where he'd written down Derek's address.

Lexie had done the same thing and handed over her paper. Mark finally found his and let out a soft sound of triumph before handing it over to the cabbie.

He spent a bit longer than either of them expected staring at the pieces of paper. "Are they further away than we thought?" Lexie asked, regretting that they hadn't actually compared addresses before grabbing a cab together. She was just hadn't been ready to say goodbye to Mark yet.

"This is some sort of joke, right?" the cabbie questioned.

Lexie and Mark looked at each other, confused. "What do you mean?"

"It's the same address. I'm taking both of you to the same place."

Lexie shook her head and turned to Mark again. "Your best friend's name is Derek. He's not…Derek Shepherd, chief of Neuro at Seattle Grace Mercy West, is he?"

Mark chuckled. "That's exactly who he is. And your sister Meredith – she's Meredith Grey?"

"Got it in one!" Lexie laughed. She turned to the cabbie and shrugged. "Yep, guess you're taking us to the same place!"

He shrugged and started the car, heading off towards the woods and the Grey-Shepherd dream house.

Mark shook his head and chuckled, looking over at Lexie. "So does that make you Ellis Grey's daughter?"

"Oh no, I wish! Well…except I don't, because for all intents and purposes, Mer's mom was an absolutely terrible mom, but oh man, do I wish that I had her genes. Mer is such a gifted surgeon. I mean, I'm good but she's…it's in her blood. My dad is her dad. We spent summers together growing up for a little bit…she's seven years older than I am, so she made herself pretty scarce once she got to college, but I still saw her sometimes. And then we ended up going to med school around the same time, so we reconnected." Lexie smiled softly, looking down. "I really miss her. I haven't seen her in about six months."

"So that's why you're thinking about moving back?"

Lexie nodded. "Yeah. That and the fact that I basically have a locked-in fellowship with Derek who's like…the best. I mean, you know."

Mark chuckled. "I do. Perfect Derek Shepherd. Love the guy, but it's a pain in the ass being friends with someone who's so perfect."

Lexie leaned towards him, putting her hand on his arm. "It's not like you're chopped liver over here, Mark. I mean…you're the go-to plastics guy on the East Coast. That's why I couldn't stop asking you questions on the plane – you've been at the forefront of so many procedures! It's incredible. You're incredible."

"Incredible?" he said, a wicked glimmer in his eyes.

Lexie's eyes widened and her cheeks flushed before she shook her head and laughed. She took her hand away from his arm and looked down at it briefly before looking back up at him. "Yeah. Incredible. But don't let it inflate that ego of yours any more than it already has."
