Silence plagued the room for a whole minute, which to Serena had had felt like a lifetime as she waited for their response.

Dan finally looked up at her..."How?"

Serena's eyes darted down instantly, trying to avoid eye contact "I don't know"

"What do you mean you don't know we haven't even slept together yet so it can't be mine!" Dan snapped back as Nate just looked up at the uncomfortable situation unfolding in front of him.

"I know..." she said quietly looking up at him as she tried to fight back the tears that formed.

"Then what are you trying to say Serena, you've cheated on me and you don't even know who with?"

"No"

"Then who?" Serena's eyes darted subconsciously to Nate as Dan looked between them both in shock.

"Nate?"

"Dan it's not like that..."

Raising his hands to his face he couldn't believe what he was hearing as Nate looked stunned. "It's exactly like that, you cheated on me with him"

"No Dan please, listen to me"

"No" he spat in anger "I don't want to hear your excuses Serena...I'm done"

"Dan please..." she begged reaching out for his arm, he snapped his arm away spinning around to face her just shaking his head.

"I love you" she cried.

"Clearly" he said looking at her, fighting his own tears he utters "I need some space..." before grabbing his coat and leaving.

Serena just leans against the door crying, while Nate just sat there staring at her shocked.

Finally beginning to calm down, she moves over and takes a seat on the couch next to Nate.

"Its mine?" he utters looking across at her confused.

"I think so."

"How"

"That night at the Empire with you and Chuck"

"Then..."

Serena just nodded "I remember we kissed..."

Blowing out the smoke she starts giggling before taking another sip of her cocktail.

Handing it back to Nate he takes another drag as Serena rests her head against the couch, looking up at his face "I miss this"

"Huh?" he glances to her placing the joint back onto the table, before leaning back with her.

"I said I miss this...us watching films, drinking, just like we used too."

Nate just smiled at the memory of it. "I'll always remember that time me, you, Chuck and Blair went to see Space Jam."

"Oh yeah, we all loved that movie..."

Laughing Nate replies "Yeah, until Chuck accidently spilt his drink all over Blair"

"And all over her new Louis Vuitton Purse" Serena added laughing.

"Yeah she was not happy. I think I've actually got it on DVD."

"Really"

"Yeah, let me check" stumbling to his feet he makes his way over to the cabinet, flicking his eyes through the countless DVD's he finds Space Jam and places it into the machine. Settling down next to her he pours them both the rest of the cocktail mix, before pressing play.

One and a half bottles of champagne and room service later they were three quarters of the way though the film.

Digging her spoon into the rest of the chocolate fondant she took a huge bite of it, not taking her eyes away from the screen. "Have I got all of it?" she slurs as she licks around her mouth.

Laughing Nate replies "No" before placing his hand on her cheek using his thumb to wipe away the melted chocolate from her face, making her freeze instantly.

Sucking the chocolate from his thumb he looks up at her, their eyes meet staring and studying each other.

Nate's heart starts racing, just thinking back to the countless times they had looked at each other like that.

Serena couldn't help but feel the same way too, it was hard to know if it was the buzz of the alcohol or just the spark that still remained between the two... all she knew was she felt something for him in that moment.

Nate couldn't help it he needed to see if they could still work, leaning forward slowly and bringing her face to his he kissed her slowly.

Feeling her kiss back it became stronger and more passionate as their hands began grabbing each other.

"I really am sorry for everything" Serena blurts out pulling her lips away from his.

Nate's eyes looked back up at her slowly "I know you are."

Staring at each other for a moment Serena could feel the pain in his eyes as he looked down at her and it killed her to think she had caused it. Wrapping her arms around his neck she pulled him down on top of her and began finding his tongue with hers as her hands slid down to cup his face.

Letting her one hand go free she began helping him take of his shirt, pulling it over his head he tossed it to the floor as he went and began kissing her jaw line. As his left hand gripped the back of her neck his other slid up her thigh making her moan slightly at his touch, he began pulling down her red laced throng before discarding it on the floor.

Pulling himself up straight he undone his trouser button before sliding his trousers and boxers off in one quick motion, stepping out of them he led back down on top of her as she wrapped her legs around his hips.

Looking down as her eyes glistened in the light he shook his head in almost disbelief "I love you" he whispered as Serena nodded before replying softly "I know."

His lips smashed against hers as he slowly made his way along her neck before lifting her dress up slightly.

Moving his hands slowly up her thighs, stopping at her hips he slid into her in one quick motion making her moan in pleasure...

"I do too, I can't remember much of that night"

"Neither can I... I remember waking up the next day asleep on your lap, resting my head against your chest." Nate just looked to the floor, as his mind had a slight flashback.

"What's wrong?"

"Oh god... I just remembered something"

"What?"

"Well I was doing the buttons up on my trousers and knelt down to pick up my shirt... as you began pulling down your dress. You whispered to me 'That was incredible' I agreed and..." He said trying so hard to think back. "That's it, that's all I can remember." Nate said in annoyance.

"I can't even remember that" Serena laughed slightly before realising what that meant. "So it did happen?" Nate just nodded.

"So where do we stand in all of this?"

"Look" Nate began turning around to face her taking her hands in his "I'll be there for you, however you want to deal with this. If that's coming with you to have an abortion or coming for the scans and classes, I'll be there to support you every step of the way." Serena just smiled so touched by his words.

She had been so worried and nervous at how he would take it and seeing him willing to support her no matter what, really made her realise why she had fallen in love with him all those times and why apart of her still did.

"Thank you" she smiled leaning forward and hugging him.

"So have you thought about what you want to do?"

"I'm going to keep it. I'm sorry I've had to put you in this situation, but I can't tell you how pleased I am that you're going to help me though this."

"Of course, I got you into this mess the least I can do is be there to support you through it. It does takes two you know" he winked playfully as Serena just laughed slightly before hitting him.

After a moment she began looking to the floor upset..

"Dan will come around, I can tell you're really worried and upset about how he took it."

"I really fucked up this time Nate"

"Hey, look at me" he said as she glanced up at him. "Your Serena Van Der Woodsen, you'll pull through this. Plus how could Dan ever stay mad at you, especially when we both can't even remember what happened...fully" he smirked.

"I know, but we have the proof of it"

Nate just nodded slightly not sure how to reply. "Look I've got to go, tell Dan it was my fault... I did kiss you first after all"

"Nate you don't have to..."

"Serena its fine...I'm fine" he breathed out clenching his jaw tightly "I don't want this to ruin the two of you especially after everything. I'm your friend and his, and if you need anything and I mean anything at all let me know. That goes for both of you" he smiled tightly gesturing towards her stomach, placing a kiss upon her forehead, he left.

Closing the door behind him he rushed around the corner, collapsing to the floor he was desperate to breathe.

He felt like his lungs were starved of air. Clutching his chest he let out a dull cry, finding it so painful to not admit the truth to her. Part of him was ecstatic to become a father especially with Serena, but a part of him died knowing it didn't really change a thing.

Serena was having his child, Serena... he thought to himself. It shook him immensely to find out but had filled him with so much promise to, only to have them ripped away like that. Pulling himself up off the floor he took in a deep breath trying to calm himself, he could feel his heart racing and the air continuing to escape his lungs.

He needed to get out of there and fast...he felt sick, unable to breathe.

As he ran down the stairs he took his phone out of his pocket, dialling the first person he could think of "Hey man it's me, I really need you right now... is there any"

"I'll be there, see you at the Empire" he replied instantly noticing the panic and state Nate was in.

"Not there..." he interrupted.

"Ok, how about 21?"

"I'll be by the bar" Nate replied erratically before hanging up.

"Is everything okay?"

"I'm sorry I have to go, Nate needs me" he announced standing up before walking off to pick up his coat.

"Hey what's wrong, is it Serena?" Blair said pacing after him.

Chuck just glared at her in confusion "He didn't say...why, what do you know?"

"Nothing"

"Blair..." he said tilting his head knowing she was lying.

"Bass" she smiled innocently.

"Blair..." he repeated

"Serena's pregnant..." she said looking down at her feet, knowing she would have to give in eventually.

"What"

"Its Nate's" she added as Chuck smirked at the news laughing slightly.

"Bass..." she asked knowing when he was hiding something too.

"They slept together at the Empire a few weeks ago."

"How do you know that?"

"Now that would be telling" he said running his fingers across her jaw line before placing a kiss on her lips.

Slipping on his coat he pressed the button for the elevator again.

"Bass..."

"Tell Eleanor and Cyrus I'm sorry, but I really have to go"

"We are discussing this when you get back, you're going to tell me how you know that."

"How about I show you...later" he winked getting into the elevator as the doors closed behind him, Blair just smiled.

As he walked into club 21 all he could see was a shaken up Nate sitting at the bar alone doing shots.

"Don't you think you should calm down a little..." Chuck said placing his hand across his back before sitting next to him "We have all day."

"Hey, thanks for meeting me..."

"Course, two of your finest scotches please" he gestured to the bartender.

"Serena's pregnant...and it's mine" he laughs slightly still in disbelief, playing with the shot glass in his hand.

"You love her though don't you?"

"Yeah, of course"

"Then I don't understand?" Chuck replied, passing him his scotch as he takes a sip of his own.

"That's just it, it doesn't change anything. It doesn't matter that I'm the father."

"Of course it does Nathaniel, she might still be with Humphrey but that still doesn't take away from the fact that you're the child's father."

Nate just looked down into his scotch, swirling the liquid around as Chuck continued "be there for her, prove to her you're the man she deserves to be with, not some pauper in Brooklyn. Your having a baby with her Nathaniel...nothing is more important than that."

"How can you be so sure"

"Just look at me and Blair... I never thought about having a child, let alone at twenty. But I've honestly never been happier, because the woman that's carrying my child means the world to me. I love her more than anyone could ever imagine, just like you and Serena."

Taking the glass away from his lips he just looked to Chuck slightly, realising what he had said was completely right. "When did Chuck Bass become so good at giving advice?" Chuck just laughed.

"I'm fine B I promise. I'll be home later to tell you how it went...when he finally comes back. S x" Serena typed into her phone before pressing send.

Serena just wished Dan would come home so they could sort this all out properly, they would have too she thought to herself because she wasn't leaving until it was.

Walking around the loft she needed to find something to pass the time, noticing his laptop she walked over and sat down in front of it.

Shaking the mouse, it slowly came back on opening up to his emails. Flicking through them she saw emails to Alexandra, Jenny, Junk mail and a hotel booking... Clicking on it, it was a reservation for the Roosevelt Hotel including a dinner, as well as a bottle of champagne reserved at mad46 their rooftop lounge.

Serena's heart sank when she looked down at the date he booked it for, "today" she whispered to herself.

They wanted it to be perfect and he was going to surprise her with a romantic weekend together. She just sat back in the chair staring at the screen blankly, she couldn't believe she was meant to be having a romantic weekend together with Dan but instead they were almost broken up.

Looking to the clock at the bottom of the screen another minute had passed. It had been over an hour since she told Dan the news and got the reaction she had dreaded, but what hurt the most was that he didn't even want to hear her out or let her explain.

Hearing the door click open she span around in her chair to see Dan closing the door behind him.

Throwing his coat on the couch he walked into the kitchen placing a carrier bag onto the counter. Running his hand though his hair he took in a heavy sigh and glanced around the room quickly...before looking back up to see Serena sitting there looking at him.

Looking across to her he was still unsure of what to say, having been so hurt and upset by her betrayal he couldn't bare to be in the same room as her. Yet the clear look of sadness in her eyes was eating away at him the more he looked at her. He couldn't help but feel that deep down she was devastated too.

What was she even still doing here he thought to himself, he expected her to have gone ages ago...to sort things out with Nate and their new family. The bitterness of his thought shocked him slightly but at the same time didn't, he was upset and clearly angry.

With his arms spread out holding onto the kitchen counter he looked down at the bag, he couldn't look at her any longer "what are you still doing here Serena?"

"Why didn't you tell me?"

"Tell you what?" He looked up at her confused.

"That right now...we should be on our way to the Ritz to spend a romantic weekend together, yet you can't even look at me"

"and do you blame me Serena..." He said looking to the side quickly trying to calm down, "you cheated on me, and you're having a baby with Nate... How do you expect me to feel?" he asked before answering "Hurt, betrayed...Because I do."

"It isn't like that Dan, if you let me explain you'll see..."

"See what?" He interrupted snapping at her, "that you really did love me and didn't mean to hurt me?"

"Yes"

"It's too late, you already have" he said defeated, shaking his head.

"Dan please, what happened with Nate meant nothing...neither of us can even remember it. We were both too drunk and stoned to know what we were doing." She got up out of her chair and walked over to him.

"You know I would never have left Nate if I didn't love you, so do you really think I would risk what we have by sleeping with him intentionally" Dan just looked down "No.." she whispered, answering her own question "I wouldn't...because I love you Dan" She announced, reaching her hands out to touch him.

"Don't" he spat tearfully bringing his hands away from her. Looking up at the ceiling he needed a moment to try and compose himself "I can't do this anymore Serena. It's bad enough that you cheated on me...and with Nate. But to fall pregnant by him as well...it's killing me..." he said bluntly as tears fell along his face.

"I know" her lip trembled slightly. "It's killing me too that this baby isn't ours Dan." Dan just looked back up at her face, studying it carefully.

As her eyes began to fill she continued "But I can't...I can't get rid of it. I have to start growing up and taking responsibility for what I've done." Dan just nodded.

"But I honestly can't imagine doing this without you, I need you to help me through this" she sobbed as she began pouring her heart out. "I know this isn't our child, that I always pictured it to one day be but that doesn't mean I want this to end..." She cried looking at him for his answer...nothing.

She had nothing more to say, she had said everything and poured her heart out to him and still got nothing. There was nothing more she could do but wait.

"I think you should go..." She said looking around trying to think clearly. "Go, spend the weekend away at the Ritz" she announced grabbing her purse. "If you still feel like this is it for us after that...then, that's fine." She smiled at him slightly trying to pull herself together.

Rubbing the tears from under her eyes she threw her coat over her arm and left. Dan just looked on and watched her leave, as the door slammed shut and echoed around the loft all he could do was think she was completely right.
