Callie and Arizona were sat in the cafeteria talking when Meredith walked up dropping her tray on the table.

"Men!" She exclaimed.

"What did Shepherd do?" Arizona inquired recognising the annoyed by the one you are with tone.

"Why are men such jerks?" Lexie dropped her tray and sat down.

"You two really are related." Callie smirked. "What did Sloan do?"

"Give me one of those." Cristina pulled up a chair and stole a French fry from Meredith's plate.

"Hunt trouble?" Arizona guessed.

"See this is the benefit of being a lesbian not having men trouble." Callie pointed out.

"Is there a class?" Cristina asked.

"Maybe you need a testosterone free night." Arizona suggested. They all looked at her. "All I was saying is you work with them and either live or practically live with them. You need a night off."

"Girls night." Meredith said.

"As long as there is tequila." Cristina agreed as Meredith's pager went off.

"My house at 7." Meredith got to her feet. "Figure out which of the four of you is bringing the alcohol and who is bringing the pizza,"

"You walked us into that one." Callie stated.

"I'm eating this." Cristina called out pulling Meredith's lunch in front of her.

Meredith open the door just before seven to find Lexie holding four pizza boxes and a carrier bag.

"Hey Lex." She let her sister in.

"I brought ice-cream too."

"I'm making margaritas." Meredith informed her as Lexie followed her into the kitchen. "Want one?"

"I can't." Lexie set the pizza on the table and put the ice-cream into the freezer.

"A few margaritas won't change you into Thatcher."

"That's not why I can't drink. This is." Lexie pulled a crumpled piece out of her pocket and handed it to Meredith.

"Who is Alexandra Black and why do you have her lab results?"

"Me." Lexie replied.

"Lexie, this says you are pregnant."

"I grabbed the results on the way out the hospital; I didn't open it until I was waiting for the pizza." Lexie sank into one of the chairs.

"You're pregnant." Meredith repeated.

"Who is pregnant?" Callie asked as she had let herself in with Arizona and Cristina.

"Lexie." Meredith replied.

"Congratulations." Arizona offered.

"You and McSteamy decided to reproduce." Cristina grabbed a slice of pizza.

"Cristina." Meredith chastised.

"I was saying he has good genes."

"What did Mark say when you told him?" Callie inquired. Lexie looked at her and then buried her face into her arms. "You haven't told him."

"Can you see Sloan changing diapers and doing 3 am feeds?" Cristina asked,

"You aren't helping Yang."

"She's right." Lexie looked up. "A week ago all I was concerned with was that he wasn't sleeping with anyone else." She paused. "He's not still sleeping with the nurses is he?"

"No." Callie assured her. "He loves you."

"No he likes me enough to not sleep with the nurses." Lexie corrected. "The only person he ever loved was Addison. But I'm a Grey; I can handle this by myself."

"You need to tell him." Callie told her.

"I will."

"I'm not an OB/GYN but from your HCG level I'd say you were seven weeks along." Arizona read the blood work. "You're not going to be able to hide it for much longer."

"Can we talk about something else?" Lexie requested.

"What do you want to do?" Meredith asked.

"Eat pizza and that ice-cream I brought and watch you all get drunk."

"Sounds like a plan." Cristina agreed.

Derek Shepherd whistled as he walked up the path to the front door. He had a successful day. He had a bemused smile when he saw a sign taped to the door stating 'no men allowed'. He put his key in the lock only to find his entry barred by the security chain.

"Meredith?" He called.

"Derek." She walked to the door.

"What's going on?"

"We are having an anti-men girls' night."

"And how long is this going to last?"

"Until tomorrow so you need to find somewhere to sleep." With that she closed the door.

Mark Sloan was flipping channels, beer in hand when there was a knock on the door.

"Finally." He muttered opening. "Not Lexie."

"Very observant." Derek walked in. "I'm sleeping on your couch tonight."

"Fight with Meredith?" Mark guessed.

"She's having some anti-men girls' night so I got kicked out. Lexie is probably there."

"She didn't mention it." Mark grabbed his cell phone and dialled her number.

"It's Mark." Lexie recognised the ringtone without needing to check the caller id.

"I've got it." Callie grabbed the phone. "No." She answered.

"Callie? Why are you answering Lexie's phone?"

"We're having a girls' night so no she can't answer your booty call."

"Callie." Lexie lunged to grab her phone but she had moved around the table.

"So you'll have to find something else to do. And when I say do I don't mean anything that involves getting within ten feet of another woman. That goes for Hunt and Shepherd too as you all have girlfriends who are very good with a scalpel. Goodbye." She hung up.

"Torres and Yang are there too. We are to avoid other women or they are coming after us with scalpels." Mark informed. "Do you want a beer?"

"Sure."

Lexie was waiting for Mark when he got home after spending the entire day reconstructing a woman who had been mauled by her neighbours' dog.

"Hey." He walked in and gave her a kiss before noticing she had her coat on. "Are you going somewhere?"

"We need to talk." She moved so she was stood between him and the door.

"That's never a good start to a conversation. What do you want to talk about?"

"I'm pregnant." Lexie blurted out.

"What?" He looked stunned.

"I'm pregnant." She repeated.

He started to pace as he processed, Lexie watching for a moment.

"It's okay." She interrupted. He stopped and looked at her. "This wasn't what either of us signed up for. I'm perfectly capable of taking care of the baby by myself."

"Lexie." He started.

"It's okay." She repeated before kissing him slightly longer than necessary. "Goodbye Mark." She grabbed her bag trying hold back the urge to cry and she was out the door before he could say anything.

Fifteen minutes later she was knocking on Meredith's door, her eyes red.

"Can I stay for a while?" She asked when Meredith opened the door.

"You told him." Meredith guessed. Lexie nodded. "Come here." Meredith wrapped her in a hug."You can stay as long as you like." After a few minutes she suggested Lexie go upstairs.

"Who was at the door?" Derek asked when he looked up from his paper.

"Lexie, she is staying for a while."

"Ok." Derek agreed watching Meredith retrieving some ice-cream.

"And if you have any pent up feelings of aggression towards Mark Sloan now would be a good time to act on them."

"What did he do?"

"Lexie is pregnant."

"Mark knows?" Derek set the paper down. Meredith nodded. "I'll be back."

"Don't break your hand and tell him he isn't allowed in the house."

Mark got up from where had been sat with his head in his hands since Lexie had left when Derek started pounding on the door.

"I take it you heard the good news. Go ahead I'll give you one shot for free."

"What did you say to her that she is now living in my house and crying her eyes out?" Derek demanded.

"I didn't say anything. She's crying?"

"What?" Derek was thrown by his response.

"She told me she's pregnant, before it had a chance to sink in she said she could handle it by herself, she kissed me goodbye and walked out."

"What would you have said if she stuck around?"

"I don't know." Mark admitted leaning against the wall. "A kid is a big deal. Lexie is just a kid."

"She's twenty-four and a doctor, give her a few years and she will be an excellent surgeon." He paused. "You knew how young she was going into this despite my warning."

"I know." Mark rubbed a hand over his face.

"Do you remember when you used to come over for dinner when the whole family, it was loud and raucous and kids everywhere?"

"Yes." Mark nodded.

"You told me that's how families should be. I think Lexie is going to a great mom, and she'll figure out how to handle it on her own, Meredith and I will help her since she is family. But you have to figure what kind of father you want to be. You are either in or out there is no half way with a Grey. Their father screwed them up, they need black and white when it comes to relationships any shade of grey and they get hurt. If you hurt her any more a sucker punch from me will be nothing compared to what Meredith will do to you."

It had been a week since the revelation and Lexie was filling Callie in on their latest patient.

"Ok, Mr Forsyth, I'm going to take another look at your x-rays but you are going to need surgery. Dr Grey will be back to prep you as soon as we have an operating room free. Dr Grey." Callie nodded out the door.

Callie waited until they were outside before she spoke again.

"Do you want to scrub in?"

"Of course." Lexie smiled but Callie noticed how tired she looked.

"How long have you been on your feet?"

"What time is it?" She glanced at the clock. "Eighteen hours."

"When was the last time you ate?" Callie asked watching her think. "Obviously it's been too long. Juice and cookies from the vending machine."

"I'm ok." Lexie assured her.

"I'm not having you pass out in the middle of surgery, you either eat or I'm putting you on a drip. It's not just you you have to worry about anymore."

"Okay." Lexie conceded.

Callie found Mark reading a chart.

"Come with me." She grabbed his arm and dragged him into the nearest empty room and pulled the blinds.

"Finally decided being a lesbian isn't going to work out?" He joked.

"You're an idiot." She cuffed him upside the head.

"Ow!" He exclaimed rub the spot. "What was that for?"

"You owe me $10."

"For what?"

"Feeding your pregnant girlfriend who has been on her feet for 18 hours and hasn't eaten in longer than that before she passed out."

"Is she okay?" He was instantly concerned.

"She's fine. But why the hell haven't you talked to her? Do you really object to the idea that much?"

"No, I want Lexie and the kid."

"It's been a week, why haven't you spoken to her?"

"I've tried. She won't answer my calls, Meredith has banned me from the house, she and Yang are hiding her somewhere in the hospital."

"She's been helping in peds for most of the week. If you really wanted to talk to her you could have found a way around Meredith. She didn't get 2 months pregnant by herself."

"What?"

"You really didn't talk to her did you? She's about 8 weeks."

"You know more than I do. She told me and left and I haven't spoken to her since."

"If I tell you where she is do you promise not to disappoint her?" Callie asked.

"Torres!" Mark said a warning tone.

"She's in the on call room putting her feet up before she has to start preparing my patient for surgery in half an hour."

"Thank you."

Lexie was finishing her sandwich when the door opened.

"Dr Sloan." She said.

"Drop the formality Lex, we need to talk."

"I have to prep a patient for surgery." She started to get up.

"Not for twenty minutes. Why did you wait so long to tell me? Everyone seems to know more than I do." Mark demanded.

"I didn't. I told you the first time I saw you after I found out." Lexie stated, Mark waited for her to say something else. "A patient asked how soon she could start trying for a baby and it made me realise I was late. I drew some blood. I picked up the results when I was headed out the door to Meredith's and opened them while was waiting for my order at the pizza place. I only told her because I needed to tell some and everyone walked in."

"Why didn't you stick around?"

"I'd run that conversation through my head so many times, I knew how it would play out. It was easier on both of us that I left."

"It's nice to know you have so much faith in me." He crossed his arms.

"I know what happened with Addison..." Lexie started.

"This has nothing to do with Addison; this is about you and me."

"You don't have to worry I'm keeping the baby. When I came to your hotel room that night I knew how you feel about commitment, you've only just gotten used to me sleeping at your place on the nights I'm not here. This was an accident, neither of us expected my birth control pill not to work, but I can deal with this by myself." Lexie was fighting not to cry.

"It's nice to know you think so little of me. This is my kid too."

"Mark..." Lexie started but a tear ran down her cheek.

"Don't cry." He wiped the tear away with his thumb.

"I'm taking tears over morning sickness." Lexie whispered as he held her face in her hand.

"I want to be involved Lex." He kissed her.

"No!" Lexie pulled back once her brain caught up. "I can't do this." Her pager went off. "I have to go."

"It's my kid too." Mark repeated causing Lexie to stop her hand on the door handle.

"7am tomorrow, Dr Chang in OB." She said before leaving.

Lexie was leaving her appointment when she literally ran into Mark.

"Sorry I'm late." He apologised. "I got stuck in the pit."

"I told you I can do this by myself. Dr Chang needs you to fill out a form with your family medical history."

"I'm here now doesn't it count for something?"

"Can you just fill out the form?" She requested as her pager went off. "I have to get back to work."

"Lexie... He called after her. "I love you."

"No you don't." Her back towards him as she paused before continuing to walk away. "You just think you should."

Mark sighed as he watched walk away before backtracking to Chang's office.

"Dr Sloan, you just missed Dr Grey. But since you are here there is a form I need you to fill out for me." He passed the form to Mark.

"Are they both ok or can't you discuss it?"

"Lexie gave me permission to discuss any aspect of her pregnancy with you. They are both happy and healthy. Her due date is February 1st. She forgot take this with her." He handed Mark a copy of a sonogram picture.

"Can I get a copy?" Mark asked transfixed with the picture.

"Of course." Dr Chang got him an extra copy.

"Is there anything else I should know?" Mark asked.

"She's an intern, she works long hours but it takes a lot of energy to create a person, she needed to get plenty of rest and eat at regular intervals. Any questions you have you both of you know where my office is."

Mark walked around with pictures in his pocket while he trying to figure out his next move when he saw Meredith carrying a stack of charts into an empty room.

"Grey."

"If this is about Lexie." Meredith said.

"Look I can't get her to talk to me for more than a minute and when I do she doesn't believe anything I say so I need you to give me five minutes." He requested.

"Fine."

"I love your sister even if she doesn't believe me," He started.

"She would be more inclined to believe you if you had told her before you found out she was pregnant."

"Look I've had a lot of time to reassess a lot of things this last week. Lexie and your niece or nephew here." He put the scan picture on the desk, "Are the most important people in my life."

Meredith picked up the picture.

"Mark, you are not exactly the white picket fence and soccer game type. You slept with half the female staff."

"People change. I haven't slept with anyone else since Lexie showed up at my hotel room and took her clothes off."

"We're damaged, we have a father who disappointed us, and Lexie can't take any more disappointment."

"I won't disappoint her." Mark assured her.

"It's not me you have to convince."

"You're her sister how do I do that?" Mark pleaded. "When she doesn't believe a word I say."

"Action sometimes louder than words. If you are serious you are going to have to prove it her and keep proving it to her until she believes you."

"Thank you Meredith." Mark smiled with slightly more hope.

"If you screw this up..." Meredith started.

"I know you'll come after me with a scalpel."

"After I find her the meanest badass lawyer on the west coast to sue you for every dollar you make in the next twenty years in child support."

"Sounds reasonable."

"You can start by not adding anymore nurses to your score card." Meredith handed him back the picture. "And we never had this conversation."

"Can you page me when Mrs Donovan gets here?" Lexie handed the nurse the chart.

"These were delivered for you." A nurse set a vase of white, yellow and pink Gerbera daisies, Lexie's favourite flower, on the counter. "There is a card."

Lexie extracted the card from the envelope.

I meant what I said.

I love you.

M x

P.S I think you forgot this.

Lexie saw the scan picture in the envelope, she stuffed it and card into her lab coat pocket.

"Did you have a fight with Dr Sloan?" The nurse guessed.

"We broke up a week ago." She paused. "Put these in Mrs Miller's room, she could do with cheering up. Excuse me."

An hour later Mark walked up to the nurses' station.

"Do you know if..."

"Dr Grey got the flowers you sent her?" The nurse interrupted. "She had us put them in one of the patient rooms. She said you broke up."

"We didn't break up we had a disagreement." Mark corrected. "Excuse me."
