Where the fuck am I? Was the first thought that went through Allison Cameron's mind as she woke up to an alarm going off. The groan she heard beside her certainly didn't belong to Chase. Opening her eyes she flipped over to come face to face with Thirteen. "Shit!" her eyes widened and she jumped out of the bed to discover she was naked.

Thirteen chuckled at her co-worker. "How much of last night do you remember?" She asked Cameron as the blonde hugged a bed pillow to herself.

Cameron paused to think about the question and sat back down on the corner of the bed. "We were at House's, and I ditched Chase with Foreman, and then we were at that lesbian bar and…Oh." She stopped. Thirteen grinned.

"So am I better than Chase?" she raised an eyebrow at Cameron.

"You're…naughtier than Chase." Cameron decided. "I like that."

"Thought so." Thirteen hopped out of the bed. "You shower first, I'll make coffee." She pointed Cameron in the direction of the bathroom and pulled on a shirt and underwear. Cameron complied.

At the Hospital…

"So did you two have sex?" House demanded as Thirteen walked in the door.

Thirteen deadpanned. "Yeah. It was hot." She grabbed a folder off the table and took a seat. "Where are Taub and Kutner?"

House shrugged. "Dead in an alleyway for all I know."

Thirteen rolled her eyes. "At least we have a case."

"And here I thought you enjoyed discovering Cameron's inner badass." House smirked at her.

Taub saved the day by stumbling into the room.

"You look like hell." Thirteen informed him.

He groaned. "I know." She took momentary pity on him and got him a mug of coffee as he collapsed into a chair.

House grinned. "How does it feel to be out-drunk by two girls and be the only one with a hangover the next day?" he taunted as Taub pinched the bridge of his nose.

Kutner made his way into the room, effectively voiding that statement, accompanied by Foreman, who seemed to be unharmed by the previous night's activities.

Elsewhere…

Chase entered the ER, planning on demanding why his girlfriend had abandoned him last night. That type of behaviour was completely unacceptable!

"Robert." He whirled around to see her come through the doors behind him, carrying a cup of coffee.

"Allison." He replied grumpily.

"How was the rest of the night?" she questioned, taking a sip of her coffee.

"You left me in a corner!!" He burst out, attracting the attention of several nurses and patients. Cameron led him out into the hallway calmly. Chase was so difficult to handle sometimes!

"You were in one of your states." She pointed out. "I didn't see why it should ruin my evening!"

"You put me in that state." He shot back, pouting.

"We were playing a game Chase. God!" She crossed her arms and looked at him severely. His resolve weakened.

"You kissed Thirteen." He whined, pleading.

Cameron rolled her eyes. "Grow up, Chase. You'd think you would have gotten used to House's games by now."

He looked at the floor, dejected. "Okay." He turned and slowly walked back towards the elevator. Cameron walked back into the ER, Chase disappearing from her mind immediately.

In a Random Hallway…

"House!" House sighed as he heard Cuddy's voice floating down the hallway after him, accompanied by the click of heels. "What is this I hear about a drinking competition last night?"

House turned. "You should have been there, Cuddles. I set the old ones against the new ones. Cameron and Thirteen made out. It was awesome!"

"You're so full of shit." Cuddy examined him disbelievingly.

"You don't want to know who one?" House asked, waggling his eyebrows.

Cuddy sighed. "Not really." She glared at him. "But I would really appreciate it if you weren't the cause of your employees coming into work hung over in the future."

"It stops Taub and Kutner from making stupid suggestions." House pointed out, scratching his stubble. "Differentials are really much more effective with just Thirteen and Foreman there."

Cuddy rolled her eyes. "Then fire them and reduce your payroll."

"Nah. Need 'em for grunt work."

"Whatever." Cuddy rolled her eyes and walked off. House watched her ass wiggle away. There was really no escaping how hot Cuddy's ass was.

In House's Office…

"So, would you want to go for coffee later?" Foreman asked Thirteen, attempting to be casual. Taub and Kutner sat in stupors at the table. Thirteen plonked herself down in a chair and looked up at him.

"No."

"How about tomorrow?" He asked, not put off by her obvious lack of interest.

"No."

"Well, when are you free?" He tried again.

She sighed. "Foreman, in case you hadn't noticed House's multiple comments, I mostly sleep with women."

He looked at her dreamy-eyed. "Yes…"

"So…" she trailed off, raising her eyebrows and hoping he'd get the point. He didn't. She sighed again. "So I'm not interested."

"Oh." Foreman looked hurt, and flipped through the file slowly.

"So now the patient is improving, what the hell are we meant to do with our time?" Thirteen asked in frustration. "I'm not going back to the clinic again!"

"You could go to the ER and make out with Cameron for my benefit." House commented as he limped into the room.

Thirteen gritted her teeth. "It seems to cause large amounts of distraction when Cameron and I hook up." She snapped at him.

"Yeah." House's mind wandered off into a dreamy reminiscence of the previous night. Thirteen rolled her eyes. "Well, Cuddy wants one of you in the ER anyway, and you seem bored. Off you go."

Thirteen stood up and exited the room. Something to do was better than hanging around being asked out by Foreman.

"Foreman, go to the clinic. I'm having lunch with Wilson." Thirteen heard the comment behind her and snickered.

"Hi." Thirteen turned to find Cameron smiling at her.

"Hey. House sent me up to help out."

Cameron snorted. "He would."

"So what can I do?" Thirteen questioned. At least Cameron wasn't awkward.

Cameron gestured to a stack of files. "Dive in." she invited.

Cafeteria…

House reached over absently and munched on Wilson's fries. "I need another method of getting Cameron and Thirteen to hook up." He pondered.

Wilson raised his eyebrows. "Unless you hold nightly drinking competitions at your house, I don't see how that's going to happen."

"I'll need to take Chase out of the picture." House ignored his comment, continuing to mull over the problem.

"You think if you just eliminate her boyfriend, Cameron will start hooking up with Thirteen?" Wilson said in disbelief.

House rolled his eyes. "They were obviously enjoying themselves last night. And they went clubbing. And Cameron appears to be wearing the same clothes as yesterday."

"Hmm." That was pretty good evidence.

"So the question is: how do we get her to break up with Chase?" House's eyes gleamed.

As it turned out, he didn't really need to interfere…
