Prologue

1 Year Ago

"Miss Blair! Mister Chuck is here to see you!" Dorota's anxious voice appeared before the maid's face popped into Blair's room. "Miss Blair, he shouldn't be here, if you're father knew he was here so late-"

Blair pressed her lips together to calm herself for a moment as her maid prattled on before waving a hand and instantly stopping the maid mid-sentence. "It's fine, Dorota." She snapped out as she slipped past her, and out into the hallway. "I'll get rid of Mr. Chuck."

She all but stormed down the hallway and almost stormed down the stairs but realized what she was wearing. Sighing, she stared down at the silk robe barely covering her nightgown before tightening the sash and running a hand through her hair to make sure she looked alright. Honestly, who made a house call at eleven o'clock at night? But then again it was Chuck Bass. He carried the same business hours as a vampire. Still, it was rude.

"Blair!" His voice echoed up the stairs. Obviously he was in no mood to wait tonight.

She forced out a calming breath before beginning to sashay down the stairs. "Chuck." She hissed out. "What are you doing here?"

He met her half way up the stairs, grabbed her by the arm and proceeded to drag her up the stairs. "We need to talk." He informed her as he dragged her down the hallway toward her room, completely ignoring Dorota as he all but forced Blair into her room.

Anger rose through Blair as she tried to figure out what the hell he was doing. The last time he'd been allowed in her room was before she'd found out about him and Georgina. They'd been young then. So young that she'd let him kiss her while they were watching Breakfast at Tiffany's for the first time. But those days were long over and Chuck was most definitely not allowed in her room.

"What the hell do you think you're doing, Charles Bass." She hissed at him as he closed the door, afraid to raise her voice too much out of fear of her mother and father knowing that Chuck Bass was in her room. That was something that would make her want to kill herself.

He merely began pacing the length of her room, a pensive look on his features. On a good day, Chuck was hard to read; tonight he was even harder. Nothing in his appearance gave away what he was doing here, except maybe the fact that he was still dressed in the suit he'd worn to the wedding.

"We need to talk." He repeated again.

Blair rolled her eyes and refrained the sudden urge to wrap her hands around his throat and strangle him to death. "Yes, Chuck." She said slowly. "I got that. What do we need to talk about this late at night?"

He stopped pacing, and gave her a long hard look. There was something about his look that made her feel like he could see right through her. She didn't like it at all. "What is it, Bass!" She snapped, wishing he would just say whatever it was that he came here to say.

"Were you aware that Nate was sleeping with Serena?" He said slowly, drawing out each word for as long as possible. His words were pure poison and venom, delivered with perfect precision.

The world stopped, and all the air instantly disappeared from the room.

Chuck's arms were suddenly around her, and carrying her to her bed. She hadn't even realized that her knees had given out.

The second she hit the mattress, she scrambled as far away from him as possible. After taking a long deep breath, she leaned against the headboard. She attempted to breathe a couple of times, and retranslate what he'd just told her. It didn't make sense. Nate and Serena would never…

"Waldorf?" He asked tentively, knocking Blair out of her daze.

"Get out!" She shrieked at him, suddenly realizing that tears were streaming down her cheeks. "Get out! Get out! Get out! You're lying!"

He started to move towards her again.

"No!" She yelled. "Get out!"

"Time to go, Mister Chuck." Dorota intervened as she swooped into the room, and began to usher Chuck out.

"You should never have told me! Couldn't you have just kept it to yourself?!" She screamed. "Everything would have been better then! We were perfect."

She dissolved into a world of tears as she helplessly fell back against her comforter, allowing the sobs to make her entire body shake. What did it matter anyway? Her world had just shattered with nine words. Nine simple words.

It was nearly three a.m. when she came out of her tear-induced coma. She was now sitting at her parents' wet bar, a half finished fifth of vodka sitting in front of her. It had been full a half hour ago. But she didn't care any more. All she wanted was to not feel anything any more.

Suddenly a brilliant idea seeped into her alcohol saturated mind. Nate had slept with her best friend. To make things even she had to sleep with his. She had to sleep with Chuck.

She wasn't exactly sure how she'd made it here, but here she was knocking on Chuck's door at four in the morning. The doorframe was propping her up as she used her phone to slap at the door to get his attention.

The door flung open, and Chuck stood there looking sleepy and annoyed while wearing red pin striped pajamas. Blair would have been amused if she didn't have a mission to complete.

"It's four in the morning, Waldorf." He paused for a moment, watching as she all but clung to the doorframe. "Are you drunk?"

She waved her hands as if to dismiss his question as she stumbled into his room. "That doesn't matter right now." She said suddenly find it very hard to talk. Maybe she shouldn't have taken that last pull from the bottle…

He watched her intently. "Blair…" He said slowly. "What are you doing here?"

In a vain attempt to appear more sober, she straightened up to her full height and stalked over to him. "We're going to have sex." She announced before all but throwing herself at Chuck, pressing her lips to his in a sloppy kiss.

When he'd finally registered what was happened and slipped out of his half-asleep state, he pulled Blair off him, holding her at arm's length. "Waldorf, what the hell is going on?"

She rolled her eyes at him as though he were insane. "I told you. We're going to have sex. Nate slept with my best friend and now I'm going to sleep with his." She announced, using Chuck's sudden surprise to slip out of his grasp.

"Waldorf, just how much have you had?" He asked suspiciously.

Blair didn't answer the question. Instead she started pushing him towards his bed, stumbling quite a few times along the way. "You're going to sleep with me whether you like it or not." She slurred out as she pushed him onto his bed.

He stared up at her. "If you think I'm going to be noble and tell you to go home, you picked the wrong guy."

She giggled drunkenly at him. "No." She said as she began unbuttoning his ridiculous pajama top. "I picked the right one."

His lips were pressed against hers before she even had another chance to think about what she was about to do.

There was an arm thrown across her stomach and a loud ringing in her ears when Blair awoke. And why was it so dark? She blinked slightly, forcing her eyes open a little further in an attempt to figure out where she was.

The ringing continued.

"Turn it off." A voice murmured into her shoulder.

It took her a moment to realize it was Chuck.

She immediately sat up, knocking him off her very naked body. "Chuck?!" Suddenly she remembered why exactly she'd come to his suite a couple of hours prior. "Oh my God."

"That's what you kept saying last night." He drawled out as he rolled over onto his stomach.

Her phone rang again.

"Waldorf, answer the damn phone." He growled out, chucking his pillow at her.

She slid across the bed and answered the phone. "Hello?" She muttered out, suddenly feeling sick. How much had she drank last night exactly?

'Blair? It's Nate. Where are you? Weren't we meeting at eleven?'

Was it that late already? Blair didn't know what to say to him so she hung up on him. How could he have the audacity to sleep with her best friend and then call her the very next morning? It disgusted her.

She started to throw herself back against the pillows when she remembered whose room she was in. Quickly she slid out of the bed and began pulling her nightgown and robe back on since apparently in her drunken state, she'd seen that attire appropriate to wear out of the house.

"Off to meet Nathaniel?" Chuck drawled out from the bed.

Blair froze in the middle of pulling her nightgown back on and slowly turned around to face him. Her breath caught momentarily at the sight of him all relaxed in the bed, his hair all mussed, and her panties in his hand. He was a downright Basstard.

"After what he did to you?" He continued, waving her panties for her to see, an amused expression on his face as he watched her.

Slowly, she counted to ten before storming back over to the bed. "Give them back!" She reached for her panties.

A slow Cheshire cat grin appeared on his face. "Come and get them."

Blair immediately knew she was still drunk when she fell for the bait and climbed back onto the bed. She was pinned beneath him so quickly she didn't even know what happened. All she knew was that her night gown was coming off again and she wasn't doing anything to stop him. His lips crashed down on hers again and she wasn't fighting him off.

Yes. She must still be drunk.

"Room service!"

The cheery voice awoke Blair from her horrible dream. She'd dreamt that she'd spend the entire day having sex with Chuck Bass.

Her eyes flew open.

It hadn't been a dream.

She groaned and rolled over to grab her cell phone. Moaning slightly at how far she had to reach to get it, she flopped lazily back onto Chuck's pillows. Afraid of what she would see, she hesitated a moment before slowly flipping her phone open.

Six missed alerts.

Missed text: Nate 11:31am: Blair? U lose signal? Where r u?

Missed call: Nate 11:35 am

Missed text: Nate 11:41 am: Where r u? R u ok?

Missed call: Nate 11:50 am

Missed text: Nate 11:55 am: Wtf, Blair? I guess Ill c u later…

Missed call: Daddy 5:50 pm

Frowning, she exited from her missed alerts and looked at the main screen. It was just after eight. She'd just spent an entire Sunday having sex with Chuck Bass. She felt ill.

Cursing herself under her breath at how stupid she'd been last night to throw herself at Chuck, she rolled out of bed just in time to see Chuck enter the room, rolling a cart of food towards her. "I didn't think you'd want Juan to deliver it."

She froze. Chuck Bass was being nice to her.

The world must be ending.

All thoughts disappeared from her mind when he lifted the trays to reveal her only her favorite foods.

Chuck Bass noticed more than she realized.

Slowly, she slipped back onto the bed. After all, it would be rude not to eat, and she hadn't eaten all day.

For the next couple of days, Blair would continue to regret her decision to stay for room service with Chuck. One mistake turned into being pushed into broom closets in between classes, and having sex in the back of Chuck's limo. She was so mad at Nate, and so lost in the sexual world Chuck had thrown her into that she didn't even realize that Serena wasn't returning her text messages.

She leaned back against the pillows on Chuck's bed, flipping through her text messages, trying to figure out when the last time it was that she'd heard anything from Serena. Of course she was still mad at her, but it was still strange to Blair that she hadn't heard from her.

"If you're so worried about dear Serena, just call her house."

Blair's gaze shot up from her phone, and she glanced over at Chuck. She hadn't even realized he'd returned to the bed. Immediately, she looked away from him, and closed her phone. She hated how he seemed to know everything.

"Fine." Chuck said as he snagged the phone out of Blair's hand. "If you won't do it, then I will."

Horror rushed through Blair as she attempted to grab her phone back from him, but he easily grabbed both of her hands with one of his.

"Ms. van der Woodsen, you sound as charming as ever. Is Serena home?" He paused for a moment as he listened to whatever it was she was saying. "Right then. Thank you." He closed the phone, and didn't look at Blair for a moment.

She clucked her tongue impatiently at him. "Well?"

He looked at her. "Did you know that Serena was going to boarding school?"

Present

"Hey Upper East Siders, Gossip Girl here... and I have the biggest news ever. One of my many sources, Melanie91, sends us this: Spotted at Grand Central, bags in hand: Serena van der Woodsen. Was it only a year ago our It-Girl mysteriously disappeared for quote 'boarding school'? And just as suddenly she's back. Don't believe me? See for yourselves: Lucky for us, Melanie91 sent proof. Thanks for the photo, Mel! Spotted: Lonely Boy... can't believe the love of his life has returned. If only she knew who he was. But everyone knows Serena. And everyone is talking. Wonder what Blair Waldorf thinks. Sure, they're BFFs but what will Serena do when she meets the new king and queen? I don't know about you, but I can't wait to find out."

Blair stopped tugging her dress back on when she saw the message Gossip Girl had posted. She blinked for a moment as she tried to register what she'd just read. A lot had changed in a year. So much that she couldn't quite picture Serena in this world any more.

She froze when she felt Chuck's arms slip around her waist, and his lips pressed against her neck.

"I'm sure you don't want your mother to come looking for us again." He whispered out against her ear. "We should probably go back out to the party."

Slowly she turned around in his arms. "Serena's back."

He grinned. "Well, things were getting boring around here… We could use some excitement."
