There they stood, Dan and Vanessa feeling very much out of place as those of the Upper East Side peered curiously at them.

"This isn't going to work," he murmured, "they know us. We can't just blend in here, no matter how much Blair dresses us up."

"Well, we have to try…don't we?"

He looked at her and sighed, "I guess we do. Just be thankful that when this is all over you won't have to go back to school with any of them."

"True," she nodded before venturing out into the crowd, trying to mingle.

Dan on the other hand was less willing to try, he just walked around the edge of the room, watching everyone.

"A little out of your element Humphrey," a voice said suddenly in his ear, and he looked to see Blair standing beside him.

"A bit," he said, his eyes drinking in the sight of the elegant brunette, "I see you're back in your's."

She nodded and looked around, "I am, but I actually kind of miss the fact that I didn't have to worry about my reputation there, but here…"

He nodded, "yeah, I get what you mean."

"How? You don't have a reputation Humphrey…"

"No, but I do go to school with them. I still hear them talking, and just because I don't show it affects me, doesn't mean that it doesn't."

"There really is more to you than meets the eye isn't there Dan?"

"I could say the same about you Blair."

There was a small pause between them before Blair sighed and moved on to what she had finally come over here for, "we need to talk," she said nodding up the stairs towards the room.

Slowly, Dan followed the brunette up the stairs, looking around her room for a moment as she closed the door.

"What happened outside of the bar, it was…"

"Wrong," he said quickly.

"Yes, very wrong," she agreed, "I mean…I'm seeing Nate, you're seeing Serena. It was just a fluke; it didn't mean anything, we just got caught up in the moment.'

"We did," Dan repeated, although it sounded more like a question.

"Didn't we," she asked turning towards him, her eyes searching his.

Dan stared Blair, confused; why was he feeling this way towards someone he hated?

Again, his lips met hers with a passionate force and he had pressed her back against the door. He couldn't fight it. As bad as he felt about betraying Serena, Blair was too irresistible and Blair felt the same way towards him.

His jacket ended up on the floor and his top buttons on his shirt unbuttoned. Blair had pushed him back onto her bed, climbing on top of him. Her dress was bunched up on her hips, grinding against him as their lips met again and again.

"I don't normally do things like this," he mustered past her lips.

"Well, it's about time you experienced something out of your element," she said with a smirk as her lips found his neck, kissing down his chest and back up to his lips.

Things progressed from their, more of their clothes coming off as the two rolled around on her bed, leaving the guests below wondering where two of their hosts had gone.

Vanessa was asking around, looking for at least Dan, getting the news from Penelope that she had seen them go upstairs. Wondering why the two had disappeared together, she headed up the stairs and knocked lightly on Blair's bedroom door before she pushed it open and gasped sharply.

Blair was on top of Dan, her dress hand been pulled off her shoulder and was now sitting in a bunch around her waist, her hands pressed against his chest, her legs on either side of his waist.

"Oh my God. I'm sorry, I'm so sorry," she gushed, although she found herself just standing in the doorway, tears welling in her eyes.

"Well, can you leave," Blair breathed, not wanting this to end, but Dan stared at her, seeing the pain in her eyes.

"Right, sorry, I'll leave you two be," Vanessa said turning from the door and starting back downstairs.

Dan, quickly grabbing his senses pushed Blair off of him and pulled his pants back on, and tugging on his shirt, following after her, leaving it unbutton.

"Vanessa wait," he called stopping her on the stairs, not caring that everyone was staring.

"What is wrong?"

"What is wrong? What is wrong Dan? I just caught you being ridden by Blair Waldorf of all people and you're supposed to be in love with Serena!"

He sighed, "look, I know what I did was wrong, I get that, but why are you so torn up about it?"

Vanessa paused and shook her head, "because. It means you'd rather be with someone you hate…than be with me."

Shaking her head, she pulled away from him and headed out of the penthouse.

By the time Blair and Dan got back to the apartment, neither of them were speaking to the other, and Vanessa was no where to be found. They didn't even bother to check if anyone else had come home and just headed into the bedroom. Dan got onto the couch, not looking towards the brunette, and Blair crawled into the bed, not looking at him. Both of them were fighting with themselves about what had happened, falling into a restless sleep.
