After a short drive, Lexie looked up at the familiar house where she had spent much of her time living when she was in Seattle. It was where she and Mark had really first started their relationship as a couple and where they would sneak around because she was living in Meredith's attic and Derek told him to stay away from her. And it was a huge part of the memories that she had with him, which hurt her a bit as she got out of the car. But she sucked it up and came in with her things.

"The bedroom at the end of the hall upstairs is open, so it's all yours," Meredith told her, shutting the door behind them as they came in the house.

"Thanks Mer, I really do appreciate all you're doing for me," she said, looking at her big sister. Once upon a time, they hadn't really gotten along because Meredith didn't like the idea of who Lexie was…as the family Thatcher raised when Meredith didn't have a father in her life. But they had grown past that to something closer that Lexie really liked.

"Of course, you're my little sister," the elder Grey smiled. "And um…that little one is my future niece or nephew, regardless of the paternity."

Lexie almost laughed a little and knew that though her sister hadn't always liked Mark and initially wanted him to stay away from Lexie, she actually had supported their relationship when they had been together and tried to make Derek see reason.

"Well, you'll be the favorite aunt…I'm almost positive," Lexie replied, smiling faintly as she looked at her stomach for a moment, thinking about how this changed so many things for her and her family.

"I'll leave you to get settled again, but if you need me…you know where to find me," Meredith went on, giving Lexie some space to get herself settled in the house again since she'd had a long day of work and flying.

Putting her bags down in the bedroom once she got upstairs, Lexie sat on the bed before laying on her back to stare up at the ceiling. Tomorrow she was going up to the hospital to tell Mark about her pregnancy, so she had time to prepare herself tonight with what she would want to say to him. Even though she knew any speeches she prepared would likely go right out the window when she faced him, she knew it made her feel better to have one in mind at least. Moving her hand to her still flat stomach, she thought about her child.

Would he or she have Mark's eyes? Of course, the majority of newborns had blue eyes at birth and it would be several months before she would see his or her true eye color, she still wondered. But a little part of her, deep down inside, hoped that her child would have his eyes because she had fallen so in love with the color and expressiveness of them. There was also a good chance her child could possibly have a photographic memory like hers or an allergy to eggs, but those would probably be things that would appear later on. For now, she knew her baby was about an inch or so long and all of his or her organs were just about formed and that they were moving more frequently now, though Lexie couldn't feel it yet because he or she was too small.

Thinking about the baby, Lexie drifted to sleep and woke up a few hours later, nauseated and feeling like she was going to be sick. Grunting, she got up and went to the bathroom, making it in time to empty the contents of her stomach into the porcelain toilet. This was, by far, the most unpleasant symptom of pregnancy thus far. When the feeling subsided, she rose up from the floor, flushed the toilet, and rinsed out her mouth before looking in the mirror. Her deep brown eyes were tired from working all night and then flying, so she knew she needed more rest later. For now, she was going to try and eat something before all the other house inhabitants came home from the hospital and their shifts.

Lexie found some soup in the kitchen and heated it up before adding some crackers for her dinner, finishing off with some water, figuring that would be the safest option. When she was done, she went upstairs for the night and changed into her pajamas…one of Mark's old t-shirts that she had stolen while they were dating and a pair of pajama bottoms. Curling up on the bed, she fell asleep quickly and didn't wake until her alarm blared on her phone around seven the next morning. She shuffled into the bathroom and turned on the shower before slipping her clothes off and getting in. The hot water was welcome against her skin and tired muscles as she relaxed and washed her hair and body before just standing there, letting the water roll over her back for a while.

"Alright Lexie – pull yourself together and do this because you're a big girl," she scolded herself as she started getting nervous and thought about not doing this. "You're a badass…"

When she was done showering, she made quick in getting dressed before drying and slightly curling her hair. It was almost a quarter past eight by the time she was done, so she grabbed some toast and a granola bar before heading up to the hospital. Meredith had left her the keys to her car since she rode with Derek, so Lexie took it up to Seattle Grace-Mercy West. When she parked, she got out and went in to find Mark.

But a voice from behind her caught her off guard. "Lexipedia…what are you doing back?"

Lexie turned and saw Alex Karev standing in front of her, wearing his scrubs and lab coat. Her ex-boyfriend might have been an ass sometimes, but she knew there was a softer side to him deep down that he didn't show many people.

"I uh…I'm visiting Meredith and thought I'd stop by here," she lied. Maybe it wasn't a complete lie, but not the whole truth either.

"You just…left town without telling us. What gives?" Alex wasn't going to make this easy on her apparently, but she knew that almost everyone who knew about her and Mark could guess the reason why she left by now.

"I just needed to get the hell away from here," she snapped without meaning to, covering her mouth almost immediately in remorse. Her hormones were really getting the better of her now that she was progressing in her pregnancy.

But Alex seemed to understand as he nodded. "Because of the Sloan thing…I get it."

Of all the people who would get wanting to get away from somewhere because it reminded you of the person you loved who betrayed you, it would be Alex.

"Yeah…is he uh…here today?" she asked, fiddling with her hands in front of her nervously.

"Around here somewhere – at least when he isn't glued to his phone texting Torres every five minutes since she's gone on some weekend trip with Robbins."

Lexie frowned. She wanted his undivided attention and if he was on his phone all the time, she wouldn't have that in the least.

"Do you know where he'd be?" she pressed, wanting to find him before she lost her nerve and went back to Meredith's house to sulk and lick her wounds.

"Last I saw, he was heading up to the surgical floor to do a Mandibular Reconstruction about two hours ago or so," Alex replied, drinking some of his coffee.

"Thanks Alex," she said, already going in that direction.

The surgical floor was upstairs, so Lexie walked to the elevators and pushed one of the buttons, hoping that Mark would at least be scrubbing out of surgery by now. But she knew that sometimes complications arose and he could very well still be in surgery. As she got on the elevator, she pushed the button to the surgical floor before it closed and began to take her up, the motion rocking her back and forth and making her feel nauseated for the first time since she woke up. Groaning, she put her hand on her stomach and willed that it stop right that instant since she couldn't really deal with getting sick right now.

When the elevator stopped, she darted off onto the surgical floor and found a trash can in one of the nearest bathrooms before throwing up, cursing her idea to take the elevator instead of the stairs. Going to the sink, she rinsed out her mouth again and put a mint in her mouth to get rid of the smell and taste. She looked in the mirror for a moment and jumped when someone came out of one of the stalls.

"Little Grey…" Bailey said, nodding in her direction. "I thought you were in Boston. Back so soon?"

"Um…just visiting Meredith actually," she replied, giving the same answer she had just given Alex a few minutes ago, since it seemed to be the most plausible.

"I see," Bailey said as she came over and washed her hands, eyeing her suspiciously for a moment. Lexie knew she had probably been busted since Dr. Bailey had a son of her own and would recognize the random darting into the bathroom to throw up. But she didn't say anything…surprisingly. "Your sister is supposed to be scrubbing in this morning on a surgery, so I'd check the board and figure out where she likely is."

Lexie nodded and looked down, right as Bailey's pager was going off. She muttered something about an incoming trauma before heading down. Lexie made her way out of the bathroom and went to the board to see what OR Mark was in, but caught Meredith instead. Her sister looked worried and somewhat scared, which got Lexie worried.

"Mer…what's wrong?" she asked, approaching her sister who was already donning a surgical scrub cap and holding a mask.

"Lexie, I have to go get Mark out of surgery," Meredith explained, confusing Lexie for a moment until she went on. "There's…there's been an accident. Callie…"

Lexie clasped her hand over her mouth. "Oh God…"
