Thirteen fiddled clumsily with her key as she tried to fit it into the lock. "Happy Birthday to me…Happy Birthday to me…" she murmured drunkenly, sadistically. Sighing, she leaned against the door in an attempt to reconvene her double vision into a single image. "Woah!" She stumbled, falling inwards as her apartment door jerked open unexpectedly from the inside. "Who…?" She groaned from the floor, peering up at the person in the dim light, too drunk to even be afraid.

"It's Cameron." The voice sighed, taking her hands and helping her up. "House thought you were going to do something stupid and sent me over" she explained as she helped Thirteen to the couch. "He gave me his key, but you weren't here and I don't know what bars you go to or anything so I waited." She blushed. "I probably should have just left, huh?"

Thirteen shook her head as Cameron took a seat beside her on the couch. "Thank you for waiting." She looked down at the floor. Even in her drunken state she was incredibly embarrassed. "It was kind of you."

Cameron shrugged. "No worries. I've done stupid things when I had work the next day so I know how you feel." She thought back to her evening of meth and Chase.

Thirteen eyed her, surprised. "What'd you do?" she slurred.

Cameron figured she might as well be honest. The other woman probably wouldn't remember in the morning and even if she did, Cameron doubted she'd spread it around. "Thought I might have HIV, got high on meth and slept with Chase."

Thirteen chuckled. "Nice."

"What time is it?" Cameron questioned. Thirteen stuck out the arm that had her watch on it in the other woman's direction. Cameron grasped her wrist gently and turned it so the light hit the watch face. Thirteen shivered at the contact. "Cold?" Cameron asked, looking up at her with green eyes.

Thirteen shook her head slowly. "No."

Cameron smiled. "You didn't do too badly. It's only one." She examined Thirteen carefully. "It was your birthday, right?"

Thirteen nodded, swallowing. "Yeah."

"Why go on a bender all alone on your birthday?" Cameron asked. "Not that it's my business."

Thirteen shrugged. "Why not?" She watched as Cameron headed into her kitchen, grabbing two glasses from the rack and filling them both with water.

"Most people hang out with friends on their birthdays." Cameron handed her one of the glasses, sipping from her own as she sat back down.

Thirteen rolled her eyes. "I guess I'm not most people." She sipped tentatively from the glass.

Cameron smiled at that. "That's okay, me neither. I never really made friends at work."

"Yeah." Thirteen was a little uncomfortable with the personal nature of Cameron's questions. "So why'd House ask you to come?" she redirected the conversation.

"He knows he can get me to do stuff." Cameron smirked. "Apparently I care about other human beings or something crazy like that." She glanced at Thirteen, who grinned slightly in return.

"I've heard that rumour about you."

"Only House would consider it a defect." Cameron joked, leaning back against Thirteen's couch cushions and yawning. "I should probably get going. You'll be alright?"

Thirteen nodded. "Thanks again for coming." She stood as Cameron did, walking her to the door.

"No worries." Cameron pulled on her shoes. "See you tomorrow." She headed out Thirteen's front door towards her car. Thirteen shut the door behind her, locking it and aiming for her bedroom, not even bothering to turn out the lights.

She woke several hours later, still clothed, to the sound of her alarm going off. Groaning, she rolled off the bed to climb into the shower, wincing at the shooting pain that went through her skull as she stood up. Grabbing the still-full glass of water from the living room table, she chugged it on her way to the bathroom.

A little later that morning, she headed up to Diagnostics feeling a little better thanks to the several glasses of water and two Tylenol she had taken before making it to work. Now she was just looking forward to a nice mug of coffee. Seeing that Taub was already there, preparing to make coffee, she literally bolted into the room. "How many times do I have to tell you that you can't make coffee?" she demanded, exasperated.

"Oh, you're here!" he said with relief, handing the job over to her happily. A few minutes later they were both sitting at the table with Kutner, enjoying a few minutes of peace with steaming mugs of strong coffee before House barged in on them.

"You look…not hung over." House eyed her suspiciously as he entered the room, chucking several files on the desk.

"Is that bad? Unexpected?" Thirteen questioned him sarcastically, a grin gracing her lips. House shrugged and gestured to the files. Thirteen grabbed one and started flipping through it.

Cameron saw the dark brown ponytail in the cafeteria and headed over. "Mind if I join you?" she asked Thirteen, who was munching a cookie pensively. Thirteen gestured to the chair beside her and Cameron took a seat gratefully. The place was packed. She removed the lid from her coffee and blew on it before taking a sip.

"House was pretty surprised I wasn't hung over this morning." Thirteen commented wryly.

"You'd think he'd have more faith in his own judgement of character." Cameron's eyes twinkled over the rim of her coffee cup.

Thirteen grinned. "I know, right?" she didn't object as Cameron reached over and snapped off a piece of her cookie.

Foreman sat down a few minutes later, surprised to find the two women at the same table. "How are the blood tests coming?" he asked Thirteen, taking a bite of his sandwich.

"Hi to you too." She replied in amusement. "Kutner and Taub are doing them, so I came to get coffee."

"You hate cafeteria coffee." Foreman commented. Cameron raised her eyebrows.

"I wanted a cookie." Thirteen broke off another piece and pushed it towards Cameron, who smiled, taking a bit more.

Foreman just looked confused as his two female co-workers, who had never appeared friendly before, shared a chocolate chip cookie and smiles.

"Cameron!"

Cameron turned to see Foreman jogging down the hall after her. "Yes?" she raised an eyebrow at him.

"What's the deal with you and Thirteen?" he stopped in front of her.

Cameron rolled her eyes. "We discovered female bonding." She replied sarcastically then sighed at his expression. "We sat at the same table in the cafeteria and apparently both like chocolate chip cookies. I wouldn't read too much into it." She turned and walked away, leaving a still-confused Foreman in her wake.

Still, the ER doctor found herself thinking about the brunette who had taken her place on House's team. She had always considered her prickly, but she wasn't really, in the end. She just liked her privacy and had a dry sense of humour, not unlike herself. Cameron sighed and continued to work her way through her shift.
