So I know that it's a book based fic and all that jazz, but when it comes to the show I'm a huge Chair fan, I love their scenes together, they just have so much chemistry and I know they weren't all that close in the books but I've decided to throw in a sprinkling of them. Enjoy! Reviews are Love.

Its my longest chapter, so please stick with it (:!

Guess who's coming to dinner.

Blair had a black Chloé dress on her. She pressed in her stomach and then breathed out again. Fat. She thought to herself. It's ridiculous how some insecurities always stay with you. Yes, it may have only been a dinner with her closest friends but when a Waldorf is involved, nothing is ever "only". She was very twitchy and jumpy, perhaps it was the nerves. She wanted to be a great hostess. When there was a famous Eleanor Waldorf dinner party all Blair could remember was the idle gossip flying across the room from wall to wall about her mother's infamous divorce. Blair prided herself on the fact that she was everything her mother was not. Particularly when it came to her taste in men. On that note, Nate strolled into their bedroom and put his hand on her shoulder. "You look good, Blair." He said. And at that moment, looking in the mirror Blair put her hand on his and smiled sweetly. This could've been one of the most romantic moments in the movie that was Blair's life. She couldn't believe she was about to tell this man that she couldn't marry him. He only had said four small worlds, and despite what she knew, he made her feel like the most beautiful woman alive.

He wasn't the only one with the ability to do that.

Serena van der Woodsen examined herself in the mirror. Her blonde hair cascaded onto her shoulders and her blue Marc Jacobs dress extenuated the curve in her back. She had spent a lot at Barney's this afternoon, she wanted to look good. And when Serena did her make-up to perfection, the results were amazing. She couldn't wait to see Nate and the look on his face when he seen her look like this. However, the clock was ticking. She's probably told him by now…she thought to herself. Because if she hadn't, the word awkward would be an understatement. Someone knocked on her door, she rushed over quickly. Normally Serena wasn't the type of girl who was on edge, but she had a feeling about tonight.

"Hi." Jenny said, whilst looking at Serena. She looked stunning. "There's a cab waiting for us, are you ready?" She asked with a hint of anticipation?

"Oh, I'm ready." Serena replied with her trademark 'you can't stop looking at me, can you?' smile.

Serena, Dan, Vanessa and Jenny made their way up to Blair and Nate's apartment. Looking at Vanessa in her black skinny jeans and black sequined top, Serena couldn't help but feel she was a tad over dressed. "So, Blair and Nate have their own place now,"

Vanessa began, "must be getting pretty serious. I'm glad they've finally worked it all out." She said in her all knowing tone of hers. Serena raised an eyebrow and remarked, "Yeah. But you never know what's going to happen with those two. But people who are meant to be always find their way to each other in the end, am I right V?" Vanessa and Dan glanced at each other for a second and smiled at each other. "Cheesy, S but you have a point." She replied in a more friendly tone.

Serena knocked on the penthouse that Blair had so graciously been handed, courtesy of Eleanor Waldorf. She was off frolicking somewhere in Europe, and to be honest everyone preferred those arrangements. The door opened to reveal a chloé-clad Blair who hugged Serena like she hadn't seen her in seven years, yet it had only been seven hours. "Hey, S." She said warmly. Serena had a look of discontentment on her face; Blair was certainly taking her time. What, was she invited here to watch Blair perform a show for everyone else? "You haven't told him, have you?" Serena whispered sadly into her ear Blair remained silent and looked into Serena's blue gaze. She was completely and utterly torn, between the two loves of her life. Nate Archibald and her best friend, Serena van der Woodsen.

"After tonight. I promise." Blair said with all the sincerity she could muster.

"I've heard that before." Serena said, her voice cracked with hurt. She felt like turning around and walking back out the door.

But then Nate looked at her and smiled.

As Blair continued to meet and greet her guests, Serena heart sped up as she walked over to Nate. He looked better than ever. His hair was highlighted with blond streaks as a result of his and Chuck's 'boy's only trip' to Monaco. It became somewhat of a tradition. Nate's heart was beating even faster. Serena had looked better than he had remembered…much better. "Hey you." Serena breathed as they hugged each other. Calm down. Nate thought to himself. But he couldn't calm down. He wanted to pick her up, twirl her around and profess his love to her right then and there. But he couldn't. His fiancé was kind of standing right in front of them. And they were still very much engaged. As Serena pulled back, she gave him a quick and tender kiss on Nate's bottom lip. Luckily for them no-one seemed to have seen. With the exception of little J, that is

Meanwhile, Chuck Bass was nonchalantly sipping his scotch. He rolled his eyes at the sight of Serena and Nate, the kiss was only confirming what he had already known. What angered him the most was that Blair was agreeing to marry this man, the guy who was engaged yet still kissing Serena. He removed that ridiculous monogrammed scarf of his and flung it over his shoulder; he couldn't care where it landed. He looked over at Blair longingly. He couldn't believe himself, he was Chuck Bass and he practically vowed never to feel deeply for a girl. However that all tends to fly out the window where Blair was concerned.

Flashback

"You look beautiful, baby."

Blair laughed, slightly embarrassed. "Sorry, Chuck but you do not get to call me baby."

"What, is that an Archibald-only privilege? I can't help admitting that you look good in the mornings. Especially to find you in my bed." He said playfully and Blair smiled up at him.

"Chuck Bass, the pillow Queen!" She howled and Chuck couldn't help but chuckle along with her.

"If I get to call you baby, then you can call me anything you want." He said. Then he kissed her, ever so softly. Blair liked how she always seemed to be enough for Chuck. It was like she didn't have to live to any expectations, she was free. And she did feel this way when she had been with him, kissed him and eventually slept with him. But then the guilt took over. Blair Waldorf and Chuck Bass, seriously?

"I have to go." Blair said with a tinge of sadness. She didn't like blowing him off so harshly, but she had a fiancé. Chuck collapsed onto his pillow and frowned.

"I can't do this anymore with you, Blair." He said. "I can't be the other guy. I won't be.

Me and Nathaniel have become close, you know. This is wrong."

"I know. Which is why it can't happen again."

"But we both know it will." Chuck said sadly. Once she had got dressed she turned around to face him.

"He proposed." Blair said sadly. "I accepted."

"He what? Blair you never told me! Did you have an engagement fuck before you ran back to me?" Chuck shouted, his temper flared and Blair could feel it.

"I'm sorry, Chuck, no I really am." She said as he stood up, pacing the room. She tried to grasp his hand, she tried to grasp her freedom back but Chuck couldn't even look her in the eye. Finally she put her hands on his face and pressed her lips on his with all the passion she had inside of her. He pulled back and looked at her sadly.

"Why are you marrying him, when you know that you'll always be his number two?" Chuck had finally spurted out the truth and Blair looked at him.

"We both know that's not true. He proposed to me. Nate can give me security-

"And what I can't?" Chuck retorted. "You'd always be my number one." There it was his truth. Chuck Bass emotionally attached? Things seemed to be getting more fucked up by the day.

"How the hell would you know that I was number two?" Blair snapped at him. "Whatever this is…this thing with us? Consider it over, Bass." She stormed out the door in a flurry of tears and Chuck had his hands behind his neck.

"Because he told me he was going to propose to Serena." He whispered, as if he thought she could still hear him.

End flashback.

Blair led her guests into the dining room; it had the same dining table they had all grown accustomed to over the years. There was a huge assortment of food, whatever you could name is was probably there. "I can't believe we are still associated with these people." Vanessa remarked sarcastically to Dan as they walked in. "It's not all bad, at least we get a good laugh out of them." Dan replied. Over the years mocking the upper class seemed to become a favourite hobby of the pair.

"So Nate and I have something to announce." Blair started awkwardly. Nate had kept telling her to tell everyone before dinner. Serena shot her a glare. What the hell is this? Blair seemed to be playing happy couple. She can't live a lie Serena thought to herself confidently.

"We're engaged." Nate said proudly. Everyone except Serena cheered for them and shook his hand and looked at Blair's ring finger. Serena took a bread roll and chewed on it like a cow chewing its cud. This was Chucks cue. He decided it was time to walk out of the shadows, and began slowly clapping. Serena smiled. For tonight, she decided to be an honorary member of team Bass.

"Nice work, Nathaniel. Who's the lucky lady?" Serena and Jenny giggled slightly, classic Bass could come in handy. "Blair or Serena?"

"Don't start this tonight, Chuck. What's your problem?" Nate growled.

"Nothing, Nathaniel, it's just you tend to move fast. Hell for all I know you could be engaged to Vanessa." Chuck shrugged nonchalantly. Dan felt the need to wrap his arm around her right there and then.

"Sit and eat." Nate said warningly.

"I'm starving." Chuck replied.

Chuck sat himself between Blair and Serena. Jenny then sat next to Serena and then Dan and Vanessa resided at the back of the pack, they preferred to quietly laugh and mock.

"Why tonight, Chuck? Tonight, just, just why?" Blair stammered.

"What does it matter, sweetie?" Chuck said whilst holding grazing over her chin. Blair flushed and Nate was quietly observing from the sidelines. "Want some salsa?" Chuck offered.

"Not a lot." Blair snapped.

Chuck grinned. "You don't want it hot?"

Blair decided to forget for a moment she was engaged.

"You know I do, sweetie." Then she grazed his chin with her hand.

Nate choked on his Cristal.

"Are you okay?" Serena asked urgently.

Blair got up and patted his back. He removed her hand from his body.

"I'm going out for some air." He said to her as he stormed outside.

"Seems I've touched a nerve." Chuck said smugly as Blair shot him a glance to kill.

"Thanks Chuck." Serena actually said it with gratitude.

"Go do your thing, S." He replied.

"I'm going to see him." She said it matter of factly as Dan and Vanessa were howling with laughter at this stage. She walked outside to find a brooding Nate smoking a cigarette.

"What happened in there?" She asked timidly.

"I don't know. Chuck and Blair? We're engaged, for fuck's sake. You'd think she would stop flirting with him."

Serena could tell Nate was genuinely devastated. She didn't know who he loved more, she could never tell. But she loved him, and if there was any chance, she'd take it. She would wait forever.

"Let's get out of here, just you and me. To a club or somewhere other than here. Just you and me." Serena suggested smiling. Nate smiled back.

"I should go up there again. It wasn't all that big of a deal, Serena." He replied.

"Maybe you should go. But which one do you prefer, a fun night out getting drunk or returning up there to see Blair flirt with Chuck?" Serena stated holding out her hand.

The dinner didn't stand a chance.

"Serena's still in love with Nate, isn't she?" Jenny asked Chuck.

"How would I know?" Chuck replied.

"You know everything." Jenny said. Chuck smiled, he kinda did.

"Oh this is going to get interesting." Jenny smiled back at him.
