What if Lexie had been pregnant instead of Callie? Each episode still has the same main theme, that I will likely reference, but I will make sure to address all possible changes.

I'll start with 7x12.

Let me know what you guys think!

I don't own anything.

-Start Me Up-

Lexie Grey opened her eyes and found herself in Mark's apartment. The two of them hadn't moved back in together yet, but they spent almost every night together, usually at his place. He had had to go in early for a surgery, so she had the apartment to herself. Normally she would go in with him and get a jump on rounds, but she had been extremely tired this week.

She wandered into the kitchen and grabbed a piece of fruit from Mark's fruit bowl.

She began to eat without a second thought until Callie walked into her apartment and flopped onto the couch.

"Can I crash here until work?" She asked, looking up at Lexie with angry tears in her eyes.

"Sure, everything okay?"

"Arizona frickin Robbins is moving into my apartment."

"What?" Lexie asked confused.

"She bought out my subletter's. She walked away, and now she's trying to force her way back into my life." Callie said annoyed.

"I'm sorry, Callie," Lexie said. She began to say more, but she felt a queasy feeling come over her.

Callie looked up at her. "I thought you hate apples," She said questioningly.

"I do," Lexie responded before dropping the apple and darting off to the bathroom.

She slammed the door behind her and knelt in front of the toilet, barely having time to hold back her hair before she began to puke. Like clockwork, for the past week. She was probably coming down with something, but she refused to let anyone find out because then she would have to miss work. She couldn't miss today, the Chief was getting her to help with the "chicks," and apparently that indicated that she was in the running for a potential candidate as chief resident when her time came.

She quickly flushed the toilet and began to brush her teeth.

Callie knocked on the door. "You okay in there?"

Lexie called back, "Yeah, I'm fine."

"I'm fine," She repeated softly to the mirror in front of her.

…..

Lexie walked with the Chief to help assign the first year med-students with a resident. Luckily, she would not be assigned one because she was only a third year resident, the fourth years got them.

She hoped that she could run to Mark's office and snag some of the peanut butter cups he kept stashed in one of the drawers. He claimed it was because he liked them, but she knew it was for her.

She couldn't help thinking about the apple, it was delicious. She heard about tastes changing, but she had hated apples since she was a toddler.

She quickly roused herself from her thoughts to read off the assignments.

She darted off to Mark's office to find the peanut butter cups; she knew she had about ten minutes before Dr. Altman would need her help.

As she pulled them out of the drawer, she had a thought. Morning sickness, weird cravings, constant fatigue….

What if she was pregnant?

It wasn't possible, but just in case, she ran to the clinic and grabbed a few, shoving them down into her lab coat.

Before she could run to the bathroom she got a page from Dr. Altman…..

…..

A couple minutes later, she was walking with the Chief and Dr. Altman as the Chief yelled at Teddy for marrying her patient to give him some insurance.

She was breathing heavily to try to keep herself calm and began to spout off random statistics, that just caused the Chief to grow more frustrated.

"Don't you have somewhere to be, Dr. Grey?" The Chief asked her. He was clearly desperate to get rid of her.

"No… I'm on Dr. Altman's service today." She said quickly. She wanted to scream that she had to go take a pregnancy test because she thought the boyfriend she had been back together with for less than three months had gotten her pregnant. The boyfriend who she didn't even live with and who she had wanted to try to take things slowly.

She heard the two continue to argue and the Chief said something about marrying someone you love.

She knew that Mark would ask her to marry him after he found out, and while she definitely wanted to marry him someday, she wasn't ready. Who was she kidding? She wasn't even ready for a kid. She didn't want a baby yet.

She stood awkwardly as the two continued to argue. The Chief stormed off and she walked up to Dr. Altman.

Maybe it was the hormones, or her nerves, maybe she was a bigger romantic than she thought, "Don't tell the Chief I said this, but I think what you did was awesome."

Teddy slowly nodded and walked off.

Lexie took advantage of the moment and sprinted off towards the bathroom.

….

Across the hospital, Mark had just finished his surgery and now had to work a case with Arizona, who was telling him about how Callie was threatened of her.

He sighed and gulped down the coffee in his hand. He had a feeling it was going to be a long day.

He teasingly tried to give her advice.

Behind him, Alex was flirting with his first year med student.

They walked into the room of their patient. A young girl who had Treacher Collins, a genetic defect which caused her to have no cheekbones.

Her poor parents, Mark thought to himself. He couldn't imagine having to deal with something like that, Sloan's surgeries had been stressful enough and to think of how it must feel for parents who had known their child their whole life.

The young girl loved sports and desperately wanted to play.

He felt sad when she asked about tryouts two months from now.

Before suddenly remembering another surgery that would take less healing time.

He suggested it, knowing that if he was the parents he would want his child to be able to do the things they had always wanted to do, but never been allowed to, as quick as possible.

Arizona blew him off and walked away.

…..

Lexie walked into the nearest bathroom and, after making sure it was empty, locked the door.

She sat down and got ready to take the test. She shakily took it. She then took two more.

She wrapped them in toilet paper and walked out to the sink.

In less than five minutes, her whole life could change.

As she washed her hands, she looked at herself in the mirror. She was nowhere near ready for a baby, she wasn't prepared, it didn't fit into her life plan.

As she waited, she glanced at her old texts to Mark.

Could she just text him? Or maybe page him? She knew he would be happy and she wasn't quite prepared to be happy about this quite yet.

Dr. Altman paged her before she could look. She sighed and shoved the tests down into her lab coat before storming out of the bathroom.

….

Mark tried to convince Arizona to do it his way, but she didn't listen.

He grabbed a med student and tried to show it.

She tried walking away and he told her she was a crappy listener.

He offhandedly realized that he had drawn on the med student's head with permanent marker.

….

After Lexie picked up the scan's she headed to the cafeteria. She still hadn't had a chance to check, but she was starving.

As she sat down she realized that Meredith and Cristina were talking about Meredith trying to get pregnant.

"Crap," She muttered under her breath as she sat down.

Meredith was going to kill her if she was pregnant. She wanted a baby and Lexie didn't.

She quickly changed the conversation to Alex's relationship with the med student he was supposed to be showing around. She knew she would crack if they kept talking about babies.

She laughed as the residents around her began to insult the med students.

"Wow, you all sound really old," She said with a grin, earning glares.

….

Mark smiled smugly as Arizona finally walked over and wanted his opinion.

Arizona agreed.

The patient was happy, the parents were not.

He immediately noticed, and listened as the girl desperately try to convince her parents.

He looked at Arizona, glad she had listened and given the option that the girl desperately wanted.

….

Lexie checked her pager one more time and looked around the hallway. Dr. Altman was mainly dealing with the marital side of her relationship with her patient, so she had had a pretty slow day.

After making sure the coast was clear she walked into an empty supply closet, locking the door behind her.

She slowly pulled the first test out of her lab coat and took a deep breath as she unwrapped it.

She felt tears come to her eyes as she read the results.

She quickly opened the next two to find the same results.

She slid down to the floor, pulling her knees up to her chest and letting out several deep, heaving sobs.

She quickly took her phone and pager out of her pocket. She felt frozen. She paged and texted Mark several times. He'd have to come find her, she couldn't deal with it. His surgery would take a couple hours. She glanced at her pager desperately hoping she wouldn't be paged.

….

Mark looked over at Alex and April, fighting like children.

He began to list more bad traits to Arizona. He told her that he would choose Callie over her.

Arizona was grating at his nerves. He couldn't wait to go home for a quiet, relaxing night with Lexie.

….

Lexie continued to text Mark, growing more and more agitated as minutes and hours passed.

Mark sat in the O.R.

They had just finished the surgery and nearly everyone was gone.

He was just checking his work one more time.

He gave it his seal of approval and stood up. Lexie burst into the room.

"Lexie? What's wrong?" He asked her worriedly as he began to take off his surgical gear.

"You… You haven't been answering your phone or your pager and I just really need to talk to you." Lexie said breathlessly.

"Okay, give me ten-fifteen minutes," He said looking at her.

"I…Okay." Lexie said and turned to leave. "I'm pregnant." She blurted out before closing the door behind her and running down the hallway.

Mark quickly went to scrub out.

….

Mark watched proudly as the parents gave his patient a volleyball. His mind was spinning, Lexie had told him she was pregnant and then disappeared. He knew she was freaking out. He was about to go meet her, he just wanted to make sure his patient was okay.

Arizona turned to him and asked him for advice on how to make Callie give her another chance.

Mark looked at her softly, remembering what had broken him and Lexie up the first time and what would obviously prove to be a problem now, "You bailed. When things got hard, you bailed." As he spoke to her, he knew that no matter what, he wasn't going to lose Lexie again, he wasn't going to let her run away from him again.

He walked off, ready to go find Lexie. He left Arizona to think about his advice.

….

Lexie stood outside of Meredith and Derek's doorway. She needed some time to think and wanted to talk to her sister.

She heard them talking about how some people could get pregnant on the first try and how they couldn't.

She quickly ran up to her room in the attic. She didn't want to make things worse for her sister.

….

Arizona walked into the elevator to find Callie.

"I bail. Okay? When things get hard, I walk away. Maybe it's because I grew up an army brat and I moved around every eighteen months. Maybe I never learned to commit, but I'm here now and I'm staying because I'm going to fight to make sure that you know that I'm committed to this thing. I'm not perfect and neither are you. You wanna talk about faults? How about not being able to forgive? At some point you're gonan have to forgive me and it may as well be know because I am in love with you Calliope and you are in love with me. All I'm asking for is one more chance."

On an impulse, Callie turned to Arizona and kissed her.

…..

Mark opened the door to his apartment. He had a bouquet of flowers in his hand that he had picked up in the hospital girl shop.

"Lex?" He called out and was met with silence.

He quickly took out his phone and began to dial, only to get her voicemail.

"When things get hard, you bail," He whispered softly, dropping the flower's to the floor.
