BELIEF~SEATTLE GRACE HOSPITAL

Lexie has never felt this anxious before in her entire life, not even when she was waiting for acceptance letter into Harvard Medical School or when she was waiting for her final exam results to be a medical student graduate. The anxiety of waiting was killing her and she could literally feel herself shaking from the extremely high amounts of adrenaline that was coursing through her body.

"Why is it taking so long?". She looked at her watch one more time hoping that the three minutes waiting time was up, but she still had a minute to go.

"Jesus who would have thought that a minute is this long".

She had been talking to her ever since she left the ER in a rush for the supply closet. Glancing at her watch one more time she saw that she had fifteen seconds to go. As she started to count down the seconds she felt as if she was going to pee in her pants. " How could I possibly feel like peeing when I just peed on five pregnancy tests?, this is a whole new level of ridiculousness if you ask me". She couldn't resist the urge to roll her eyes at her own silliness. "Now this is borderline crazy I can't stop talking to myself, if anyone walks in they will surely have me committed".

Sighing out loudly, Lexie looked at her watch and saw the she was three minutes and twenty second into an action that was about to alter her life as she knew it. "It's now or never, regardless of what those tests say am going to be okay, I have to be okay". Giving herself that little pep talk she took and deep breath and without releasing it she looked at the tests. "POSITIVE and a smiley face, who in their right mind comes up with these ridiculous ideas. Do I look like am smiling?, I pee on a stick and my life is changed and someones idea of letting me know that, is a smiley face. Am going to write to the a letter to the manufacturer and let them am not at all please with the whole smiley face thingy on pregnancy tests". She knew her rambling wasn't going to change the fact that she was pregnant, but she rambled when she was scared or nervous.

Lexie knew she had been in the bathroom for a while and if anyone saw her go in they were going to start asking what she was doing in there. Drawing attention to herself was the last thing that she wanted, so she quickly grabbed to offend tests and wrapped them in some tissue. put them in a plastic bag and stuffed the bag in her lab coat pocket. She splashed some cold water on to her face and tried to compose herself . She had to get to the ER before Yang realized that she had gone AWOL on her.

Lexie left the bathroom and made her way to the ER, as she was passing the surgical board she noticed that Mark didn't have a surgeries scheduled for the rest of the day. She knew she had to talk to him but she wasn't sure what she was going to say and how he was going to react. Sure they had been seeing each other secretly (for sexual reasons), for six months now, but its not like they were a couple. If she had to define their relationship she would best say that they were sex buddies. It was a good arrangement for both of them. If she had an itch she would page him or call him and vice versa. They had one rule which was 'they both could not have sex with anyone as long as they were together' in hind sight they were actually in a monogamous relationship that didn't have any emotional attachments. But this changed things a lot. "When did my life get this complicated?" she muttered to herself.

When she got to the ER and looked at the patients, she knew that she wouldn't be able to concentrate on her work with the ragging mental battle that was going on in her head. So she decided to go find Dr Bailey and let her know that she wasn't feeling well and she wanted to take the rest of the day off. Dr Bailey let her have the rest of the day off without question and told her that she would let Yang know that she wasn't feeling well. She even gave her the next day off so that she could rest and be well enough to to come back to work. Grateful that she had time to think and sort things out. Lexie went off in search of the hot plastic surgeon who had entangled her in this mess, she wanted to talk to him and figure things out together with him. Cause it takes two to make a baby and it was only fair that she didn't have to carry this burden all on her own.

As she approached the nurses station she saw the man in question standing there with Dr Torres and Dr Shepard. She almost turned around to leave him be, but there was a voice that reminded her that the sooner the better. So she made her way to where he was.

" Uhm...excuse me... Dr Sloan... can I please have a word with you?". Lexie didn't know why but all of a sudden she couldn't put together a proper sentence . Mark turned his head to face her with a questioning look that said 'what are you trying to do', but the look on Lexie's face told him that it was really important and urgent. "Its about the patient from earlier". Mark looked confused he hadn't worked with her the whole week, so what was it that she wanted to talk to him about? He questioned himself. "Uhm...okay" then he turned to Torres and Shepard and said " I'll see you guys later at Joes'". Lexie went behind the counter and picked up a random file to act as if it was the patients file and then led Mark to one of the unoccupied examination rooms. This way they could speak in private and no one would suspect a thing.

After the door shut behind him Mark looked at Lexie "Whats going on?". Lexie bit her bottom lip an act Mark was now well acquainted with "Lexie whats wrong?".

"Why do you think that something is wrong?, Does something seem wrong?, Do I look wrong...". Mark chuckled at Lexie's rambling over the last few months Mark had become accustomed to it and at times he found it really endearing, but right now it was far from it " Lexie you are rambling and I can't understand what you are going on about, so, why don't you take a deep breath and try and relax. Then you can start from the beginning okay?".

Once she had calmed down some what she realized that this wasn't the place and time to have this discussion. And suddenly she remembered that Mark didn't have anymore surgeries for the rest of the day and a plan started to formulate in her head.

"I have to talk to you about something really important, actually its life changing but the thing is we can't have this conversation here. So meet me back at the Archfield in 30minutes. I know that you don't have any surgeries for the rest of the day and you can take the afternoon off so that we can deal with this". Mark couldn't make head and tail of what she had just said, "So let me get the straight, you want to talk to me and we can't talk here so you want me to take the afternoon off, meet you at the hotel in 30minutes so that we can discuss whatever it is that has you all panicked...did I get that right?".

"That's right, ten points to boy genius!"Lexie replied enthusiastically like they had found the cure for cancer or the answer to world hunger.

Mark sighed and ran this hand through his hair, he didn't know what to make of Lexie's request but if he wanted answers he knew that he was going to play along to whatever plan she has got going on.

"Okay I'll meet you at the hotel in 30minutes, don't be late because I don't know how much of not knowing I can take". He moved closer to her and gave a quick kiss before leaving the room, he also didn't want to draw attention to himself or Lexie for being there for a long time.

After he left Lexie made her way to her locker to get her things to leave but before she did that she passed by the supply closet and grabbed four more tests and left.

BELIEF~The ARCHFIELD

Twenty-nine minutes later Mark found himself pacing up and down the lounge area of his hotel suite, he was anxiously waiting for Lexies' arrival. When he left the examination room he went the Chief's office and told him that he had an emergency that he needed to attend to and that he was taking the rest of the day off since he had no surgeries. He left the hospital and made his way to his hotel, during the drive there he couldn't stop think about what it was that Lexie wanted to talk about. He was trying to think of what was so important that they had to leave work for, was she sick?, did she want to call off their arrangement?, had someone figured them out?, all of that didn't sound very serious. So he decided he wasn't going to get himself worked up over something that he didn't know. Just as he was about to turn and pour himself a drink there was a light knock on the door and he knew it was Lexie.

He opened the door to a nervous looking Lexie and before he could even say a word she made her way in to the room. "Uhmmm...so am just going to cut to the chase and get to the point of why we are here, but first you need to come with me there are things that I need to show you" she said that while pulling him in the direction of the bathroom. When they got they Lexie opened her bag and pulled out the plastic bag that she had stuffed the used pregnancy test and put them on the counter. Mark looked puzzled and confused, before he could ask what was going on Lexie pull out more tests that were unused.

Lexie decided to explain to him what was going on " So today I was working in the ER and Yang made me go to the clinic to see if I could steal some patients cause it was really slow down there. When I was in the clinic this girl came to me and started to explain how she thought she was pregnant. I asked her for her symptoms and when her last period was. While we were talking it got me thinking about my period and that is when I realized I haven't had my period in a while and I never miss my period. The only reason to why I would be late is because for some odd reason my cycle has changed or am pregnant." Lexie looked at Mark to see if he was listening and she noticed that his gaze was fixed on the used tests. She decided to continue with her story.

"So after I finished with the patient I went and grabbed some test from the supply closet and got a few bottles of water from the vending machine. I took the tests and no one saw me and no one knows, the used tests all indicated that am pregnant. Am still trying to wrap my head around this whole situation and I thought that I should tell you as soon as possible. So here we are, I got some unused one that am going to take now and if all of them say the same thing then we need to figure out what we are going to do".

Mark lifted one of the test and looked at it, he couldn't believe what he just heard and what he was seeing "You are pregnant!...you are pregnant as in you are with child and said child is mine?". Mark's voice was trembling "You are pregnant?...you are pregnant?...you are pregnant?. Lexie looked at Mark as if he had lost his mind. "Yes, yes, yes and yes. Now if you will excuse me I need to pee on these sticks and I can not pee with you in here or you looking at me like that". Mark didn't say a word he just walked out he was still confused from what he had just heard. A baby, a tiny human being, a child. He felt overwhelmed and a sudden urge to have a drink maybe that could clam him down.

"Lexie is pregnant, Jesus how did this happen we have always been careful, I just ruined her life".

"You have not ruined my life, it take two people to make a baby. Now will you come and look at the tests that I have just taken. I only took two because I don't have enough pee for four tests". Lexie turned around and made her way to Mark's bureau and pulled out one his t-shirts that she usually wore whenever she spent time there. "Hey Mark where are the blue boxers?". Mark came out of the bath holding two of the tests that she had taken, he couldn't believe that Lexie was being casual about this whole situation.

"You just took two more pregnancy tests and you don't seem worried about what they say, but instead you want to know where my blue boxers are? Are you sure you are okay?, do I need to call someone?".

"No you don't need to call anyone and I think I'll be okay, I need your boxers because I need to take a shower then sleep. Oh before I sleep I think I'll eat something can you please call room service for a grilled cheese sandwich and vanilla ice-cream and chocolate sauce". Mark just looked at her as if she had grown another head, he was seriously starting to question Lexie's sanity. He thought about how normal people deal with such issues, did they take a shower, eat and then sleep or do they sit down and talk about whats going on in their lives. Lexie and him didn't do normal so maybe this is their way of dealing. Not wanting to upset Lexie he did as he was asked and went on to pour himself two fingers of scotch.

Just as Lexie made her way into the lounge, room service delivered her meal. She devoured through the sandwich and then went on to eat the ice-cream without so much as a word to Mark who was deep in thought nursing his drink. "Mark am going to sleep, I think better when am sleeping and I need to rest its been a big day with this life changing situation that we are in. Can we talk when I wake up if you are ready to".

Mark thought that this was a good plan, "Well while you sleep am going to go to the gym, I think that will help me think. I'll take my phone with me and if you need anything just call me and I'll be here".

Lexie got up from the couch that she was seating at and kissed Mark before she walked back into the bedroom to sleep. After the kiss Mark felt like things were going to be okay between them, he was going to as supportive of Lexie as much as she will let him, because he knew that she was going through a lot right now. What with her dad being a drank, Molly blaming her for the situation in which their family was in, Meredith treating her as if she didn't exist and the other residents being on team Meredith as if there were teams to pick. He quickly got changed and made his way to the hotel gym.

While Lexie was willing herself to sleep she started think about what she was going to do. It were times like these that she wished her mother was still alive, she knew that her mother would know best what to do in that moment. But she was dead and all she had through all this was Mark. Her dad was a none starter, Molly hadn't spoken to her in five months and although Meredith was her half sister their relationship was none existent not for lack of trying on her part.

There was no doubt in her mind that she was going to keep the baby whether or not Mark was going to be there. Once she decided that she was going to keep the baby she felt at peace with herself and decided that she will figure out the rest as she goes along. Yes she was an intern but she'll figure out how to fit her career into her and the baby's' life. Money would be tight but at least unlike other interns and residents she didn't have students loans to pay back because she got a full scholarship to Harvard. She knew she couldn't figure it all out right there and then so she decided to just go with flow and sleep.

Mean while in the hotel gym Mark was on the treadmill sorting through the mess that was in his head. His insecurities started to surface that ones that he masked very well from everyone. People have labeled him man-whore and the bad guy, would Lexie want to have a baby with someone with such a reputation?. Addison's words rang loud in his mind of how he would be a bad father and Torres confirmation to the fact. Would his friends be supportive of him? if Lexie decided to keep the baby or they would just tell him that he would be bad at it. If Lexie kept the baby would she let him into the babies life?. Would Lexie resent him for doing this to her?, would it ruin her career?, she was just an intern after all, her career had hardly started. Would he be like his parents?. By the time he had ran three miles Mark had more questions than he had answer and he knew that the only person was Lexie. But one thing for sure that he knew was that if Lexie decided to terminate the pregnancy he wouldn't be able to come back from this. He knew that it was not fair to put all of this on Lexie but when it came to his personal life Mark felt that his opinion has never mattered before,because people never asked for it and if they did they just put him down.

Mark picked up his towel and made his way back to his room, into the unknown of life altering decisions.
