"I'm pregnant" she sighed disappointedly staring at the faint blue line on her fifth pregnancy test. "This was not supposed to happen" she panicked. "I am only 24 and only just out of med school and now full time doctor. I-I-I can't look after a kid"

"Clarke calm down you're pregnant not dying. Look we will get through this and we will figure it all out after but Clarke I need you to tell me who the father is" Octavia said. "So I can kill him" She continued.

"You're not going to like it"

"What? The father? I'm sure he's a nice guy and will understand my beatings" Octavia laughed but stopped abruptly when she saw Clarke serious face.

"Oh shit your serious who is this guy Clarke?"

"Let's just say if I have this child you will have a new niece/nephew" Clarke cringed at her words preparing herself at how her roommate will react.

"Bellamy? You slept with my brother!" Octavia exclaimed. Clarke nodded shamefully in response. Octavia paced in front of her biting her thumb nail. "The one time you guys get along you sleep together and apparently don't use protection"

"It's not the first time either" Clarke admitted making Octavia stop in her tracks.

"Not the first time?! There were other times! I need to sit down" Octavia threw herself down on the chair opposite Clarke thinking things over. "When?" she asked her friend calmly.

"Whenever Bellamy came back from the army"

"Shit" Octavia bit her nail. "That's why you always picked him up and why you were both gone at the same time but you guys were so sneaky with your arguments and stubbornness to each other it hid your tracks of the thing you have something going on" Octavia grumbled.

"I wanted to tell you but Bellamy said you would freak out like you are now"

"I'm not freaking out pfft this is me calm" she clenched her fist before taking a deep breath.

"I'm just angry you didn't tell me you and my brother were dating, I would have been delighted to have know this information but the fact you didn't tell me hurts Clarke especially now since I will be getting a new niece or nephew" Octavia explained.

"I know and I'm sorry and I'm also sorry to tell you that were not dating"

"Ugh that mean you guys were just doing it" she shuddered.

"I really am sorry that I didn't tell you but there was nothing to tell when Bellamy comes back we just have sex and were not dating so there was no reason to really tell people what we do. The point is O that I'm pregnant and I know you have a lot to process of what I've just told you but I need your help to get through this pregnancy, I need a friend and my soon to be child needs at least one family member besides me around since the dad won't be around. So will you help me?" Clarke asked from the bottom of her heart.

"No" Octavia stated simply.

"Oh. Right. Okay. I understand" Clarke said disappointedly.

"No I mean No Bellamy is not going to go back to the army when he's going to have a kid. Come on grab your back were going to his house to tell him and so I can kill him" Octavia smiled at Clarke who smiled back with hope.

"Can we wait till tomorrow to tell him? I called my doctor after my first test and I'm going in for a sonogram so I truly know"

"Bellamy leaves tomorrow what time is it at?" Octavia asked.

"Twelve"

"Bellamy leaves at one think we will make it?"

"Yeah should take too long" she hoped.

"So may I ask how did you get in this situation? Like how did it all start? You and Bellamy I mean" Octavia asked curiously.

"Well..."

How did it all start? she asked herself...

Well Bellamy joined the army at 16 and Octavia was upset that she wasn't going to see her brother for two years. Clarke was sad but also happy that the pain in her butt was going away for two years. It's not that she didn't like the older Blake it's not that she did either it's just they used to argue and he used to piss her off so much. But despite their arguments Clarke knew that Bellamy had a crush on her. She learned this information when she dated Bellamy's half-brother Wells and he got really jealous. Even though she didn't reciprocate his feelings, she still flirted with him. She somehow had Bellamy's attention even though she didn't fill out properly till she was 16. Although he had her attention for a bit when he was dating Lily one of her best friends as she was slightly jealous, only slightly.

When Bellamy came back two years later now 18 Clarke was 17 and O was still 16, there was a clear attraction between Clarke and Bellamy as he had come back more tanned, more muscular and his hair was somehow the same a little short but still Curley when it should have been shaved but he told her he talked his way out of it somehow. He was wearing an army uniform which made Clarke weak at the knees; she couldn't take her eyes off him. Bellamy must have felt the same about her because he couldn't keep his eyes off her.

"Hey" he said to her in a husky deep voice, looking love struck with his dazed grin.

"Hey back" she smiled.

"Bellamy!" Octavia exclaimed jumping into her brothers arms breaking the longing eye contact between the two.

"Hey O, I've missed you"

"I've missed you too"

"Believe it or not I've actually missed you too princess, it's boring without you being stubborn and arguing with me" he smirked.

"I'll take that as a compliment" Clarke laughed. They gazed into each other's eyes once more only to be interrupted by Octavia's phone buzzing. She smiled at her phone.

"I have to go Lincoln is outside we have a lunch date; do you mind taking my brother back to our moms house but we'll meet later for dinner at Rio's? Oh and here's the keys" she passed the keys to Bellamy.

"Yeah sure I don't mind" Clarke said.

"I thought you didn't like the food at Rio's?" Bellamy asked his sister.

"Well their food has improved since you've been gone" She explained.

"Right okay. So whose this Lincoln?" Bellamy asked going into over protective brother mode.

"He's waiting I should go, see you later" She quickly said before practically running out of the airport.

"Who the heck is Lincoln and do I need to kill him?" Bellamy asked Clarke.

"Her boyfriend"

"Her boyfriend?!"

"Yeah he's the same age as you"

"Yep I need to kill him"

"And that's why I'm not supposed to tell you" Clarke laughed a bit.

"I'm glad you did tell me, I can protect her"

"You mean try to break them up"

"No I mean protect, I will be there if he hurts her and kill him myself, the army has really matured me"

"Really? I don't see it" Clarke teased.

"Your just jealous over my maturity princess" he stuck his tongue put at her.

"Very mature" she laughed and he just grinned at her.

"So what does Wells think about Octavia and her relationship?"

"He's cool with it"

"Really?" he asked shocked.

"Yeah"

"Wow okay he's not doing his brotherly duties then is he?" he chuckled.

"Come on Mr 'mature' let's go" She said helping him with his bags as they left the airport.

The car journey wasn't as awkward as Clarke expected, it was quite the opposite; they talked about what was happening in Clarke lives how after high school she was going to med school thanks to her mother despite her wishes to go to art school, her mother would rather her be a doctor. They also talked about what O, Wells and his mom have been up to. Bellamy also explained some of things he had to do in training and how he met two of his friends Nathan Miller and John Murphy. Pulling up outside Bellamy's moms house was such a shock to them because the journey felt so short with them catching up.

"I'll help you with your bags" she offered.

"You don't have too"

"I know but I want too. Plus if I help you with your bags you can make me lunch to say thanks" she grinned.

"Deal" he laughed. As they went inside Bellamy expected to be bombarded with hugs from his mother but the house was empty.

"Mom?" he shouted but no response.

"I think she's at work"

"On a Saturday?" He questioned.

"Yeah a lot of things have changed within the two years you been gone" she said.

"My rooms this way" he gestured her to follow him as he walked up the stairs.

"I know where it is. If I ever get into a fight with my mother your mom lets me stay here and I stay in your room" She explained.

"You sleep in my bed?"

"Well it sounds weird when you put it like that"

"I always knew you would end up in my bed" he smirked.

"Shut up" she laughed.

Bellamy opened the door to his room and stopped abruptly.

"You feminised my room?" Bellamy asked with a raised brow, looking mortified as he scanned his room. The walls were painted purple rather than blue, the walls also had paintings on them, his sheet was pink with animal covers and pillow cases. Thankfully his clothes and other stuff were still in here.

"Well your mom said to make myself at him so I did, plus in your letter you said you would only come back for a few days or maybe week"

"Pfft how am I suppose to bring girls here and hope they will still be turned on by this crap"

"Like this" she said as she jumped on him and kissed him. She didn't know what came over her but she had been waiting to do that since she saw him at the airport. He was a little surprised at first but he relaxed into this kiss. He closed the door with his foot and leaned her against the back of it. As the kiss deepened, layers of clothes were disappearing. He lay her down on the bed and-you get the picture.

When they finished they lay there for a while, wondering who should speak first. Maybe it wasn't such a good idea to sleep with her best friends brother.

"Well that was fun" Bellamy said trying to lighten the tension. "What brought this on?"

"You know, I have no idea"

"Great" he said sarcastically, sighing as he put his pants back on and left the room. What just happened? She asked herself.

Things between the two became awkward until later on at Rio's where Bellamy had a surprise party waiting for him. As he walked in he saw the banner saying welcome home/happy 18th even thought his birthday was a few days ago he was still over whelmed at what his family had done for him and what Clarke had done too. All of his friends were there and some of his distant relatives too.

For most of the party Clarke couldn't keep her eyes off Bellamy, what they did that afternoon was the best sex she's ever had and she's only 17 and had only slept with two people before him. She hatched a plan. She waited until he went into the bathroom and she followed him in (not in a creepy way though) and she locked the door. It took him ten seconds after he came out the stall to wash his hands to realise she was in the bathroom with him.

"Clarke what are you doing in here?"

"Look I don't know what I said before to upset you and I'm sorry but I want you" she said before practically leaping on him again to kiss him.

"Apology-accepted" he said between kisses. "But if we're going to do this, it will just be sex I have decided there will be no feelings, no attachment, no pain" Bellamy stated stopping the kiss.

"Deal" she agreed.

And ever since that moment every time Bellamy came home they would do it. She would have other relationships as well but she would make sure she was free whenever Bellamy was home so she won't be cheating.

However the last year was different, Clarke knew there was no feelings involved but this thing with Bellamy felt more real than any other relationship she had. So when Octavia and Clarke received a letter saying Bellamy was missing in action in Afghanistan, something snapped within her but she had to stay strong for her friend who was mourning over the suspected loss of her brother.

The next 10 months were rough, they still hadn't heard nothing back from the army so Octavia had been staying in Bellamy's house (which he had bought two years before with his army money) with Jasper who rented Bellamy house when he was away for a few months. Clarke decided to stay there with her to comfort her. And sure enough two weeks later it came as shock to see Bellamy entering his own house alive and well with nothing so much as a scratch on his arm. Clarke's eyes watered; she was happy he was back. She jumped up off his sofa and hugged him. Her action shocked him for a moment but he hugged her back.

"Missed you too princess" He chuckled pulling away.

"That's something I never thought I'd see" Octavia laughed through her tears as she hugged her brother with all her might.

"You scared us so much" Octavia said.

"I'm so glad your home" Clarke said joining in on their hug.

"What's all the noise?" Jasper asked coming down the stairs.

"Bellamy?" he said confused walking toward them.

"Oh my God Bro!" Jasper said running into the group hug.

"I didn't know I was loved this much" He laughed as they all pulled way to go sit down on the sofa.

"You had us all worried they said you were missing in action" Octavia said wiping her eyes with her sleeve.

"I know, I was a for a bit. I got shot in right my shoulder and my left leg hitting my main artery when I followed a guy out further into a forest area; I killed him of course but I couldn't find my way back especially since no one else followed me. So I was stuck with no map in a forest with bleeding wounds" He paused remembering the wounds.

"So I ripped strips off my clothes to tie around my leg and shoulder to stop the bleeding but it didn't last long. To be honest I thought I was going to die out there especially since I was out there for two days. I passed out so I didn't know what was happening but thankfully Miller came looking for fire wood and found me half dead. He helped me back to our base and I was flown back to Walden hospital where I fell into a coma from loosing so much blood"

"You were in a coma?" Octavia asked shocked.

"Yeah I had to get a blood transplant. Woke up just under a month ago; I got checked for any signs of concussions or anything like that got cleared and two weeks later I was allowed out and so here I am. I have a month off to heal fully until the General and co come back to Ark and we set sail for the Caribbean on September 1st" Bellamy explained leaving the three with shocked faces.

"You were at Walden hospital? I was there the other day because some of my patients from Ark hospital needed transplants which I couldn't do. I'm surprised I didn't see you there" Clarke said.

"So am I if I'd known you were there you could have taken care of me" he smirked.

"I can't believe you were in a coma Bell" Octavia said her voice trembling.

"Me either" he smiled softy. Not the best moment of his life but he had so much to live for; his sister, mother, brother, friends...Clarke.

"The point is your alive somehow you lucky son of gun but we are grateful for that" Jasper grinned.

"Thanks man" Bellamy laughed.

Since Bellamy couldn't lift anything or do much really and since no one else could be bothered to do anything, still over whelmed with Bellamy's sudden arrival they decided to spend time with each other and watch films. Took them an hour like to choose a film so they decided they would all choose a film to watch and the others would have to watch it no matter what. Bellamy chose Die Hard because he thought it was ironic, Octavia chose 27 Dresses because James Marsden, Jasper chose 21 Jump street because it's awesome and Clarke chose Sherlock Holmes because Robert Downey Jr and Jude law.

Clarke's being the longest film, they agreed to watch that last. However Jasper gave up at midnight and went to bed halfway through the film. Clarke, Bellamy and Octavia finished the film, well Clarke and Bellamy did; Octavia fell asleep on the two of them for the rest of the film. This was their chance Clarke thought. They carefully move her off the as they stood up. Bellamy grabbed a blanket from the cupboard under the stairs and placed it over his sister and kissed her head. Clarke and Bellamy quietly went up stairs trying not to wake anybody.

"So what now?" Bellamy whispered.

"I have something in mind but your hurt"

"I can take it, it just means you have to do most of the work" he smirked.

"I'm up for the challenge" She smirked back and started to walk into his room but froze for a second when the floor board creaked. 'Sorry' she mouthed before continuing on her tip toes into the room. Bellamy followed behind and closed the door. Clarke carefully kissed Bellamy putting her hands under his shirt rubbing his solid chest trying to avoid his sore shoulder. Bellamy deepened the kiss his lips hungry for more, he been dreaming of doing this for what seemed like forever. Clarke stomach filled with butterflies, a whole year had passed with no contact with each other so this was something they had both longed to do. They began to strip one another wasting no time at all. Bellamy carefully laid Clarke on the bed, their hands roaming each other bodies. He softly rubbed her inner thigh with his fingers sending tingles through her body, leaving her over come with enjoyment. He softly pecks her stomach travelling towards her neck. His lips hover above hers the sweet smell of his breath lingers as she stares in the dark abyss of his eyes. He stares back at her realising the crystal clearness of her perfect beautiful blue eyes. Eventually they kiss passionately as the sweet sensations passes through her body she realises how much she missed him making this time so much more special.

"...and then I missed my period and started throwing up yesterday, my boss told me to go home and rest. I told Raven today about it and she said 'Ill? You rarely get ill. What are you pregnant?' and then my mind clicked so after my second test I called my doctor and organised a sonogram tomorrow but I took three more to make sure" Clarke said feeling proud that she remembered all that.

"I'm glad you didn't go into too much about things but whoa all those years ago and you guys aren't dating?" Octavia said.

"No feelings is what we agreed but I don't mind because whatever we have it feels more real than any relationship I've ever had" Clarke admitted to her.

"D'aww that's so sweet"

"It won't be tomorrow, how do you think he will react?"

"I don't know but I know my brother he loves kids and should be glad he's having one but he will defiantly be shocked" Octavia guessed.

"I can't believe I'm going to be a mom" Clarke slightly laughed in disbelief.

"Speaking of mom how's yours going to take the news?"

"Crap! My mother! She's going to kill me especially since, I'm not married or engaged to this guy or even in a relationship with him and I've practically only just became a doctor and I will have to take time off in like six or so months time" Clarke panicked.

"You really think she will be that pissed?" Octavia asked sympathetically.

"Yeah, I'm gonna take another test just to be sure" Clarke said before rushing off to the bathroom.

"How many tests are you going to do? You're going to end up with 30 odd tests like Mindy from The Mindy Project" Octavia sighed as she stood outside the bathroom.

A new addition to the family, this should be a fun nine months of hell.

Well that's the first of many chapters to come Let me know what you think.
