Cameron and Thirteen walk in silence back to the office.

The intern hangs up he jacket and picks up her notepad from inside a cubby hole. "I think I'll shadow for a while – if that's okay," she says.

Cameron nods and walks down the hallway, and into a room. She gets right to work, checking the vitals of a little girl. When she goes to write down the information, she realizes she doesn't have a pen handy. She pats each of her pockets in search of one; Thirteen appears beside her with a smile and offers her an extra one.

"Thanks," Cameron says, her voice constricted by her rapidly closing throat. It returns to normal when the intern steps away – when she can't smell the girl's minty breath.

They move onto another patient's room. Cameron turns around to explain something and finds Thirteen completely engrossed in watching her – particularly the back end of her – a mischievous look in her eyes.

"You may want to write this down," Cameron says to the girl, gesturing to the notepad and pen on her lap. Her cheeks feel impossibly warm; what she's about to tell her isn't that important but she'll do anything to distract the intern's attention away from herself.

Thirteen leaves the notepad and pen sitting in her lap, her eyes intently on Cameron's soft face. "It's fine. I'll remember it. I'm a great listener."

Cameron grimaces, nodding. She wants to be mad at Thirteen – frustrated, at least – but she's not. To be honest, all she wants to do is kiss her again.

The day starts to dwindle to a close; Cameron and Thirteen have barely said two words to each other all afternoon.

House watches them through the windowed wall of a patient's room, leaning comically against a wall with his cane lifted above his head.

Cameron watches Thirteen out of the corner of her eye as the girl steps out into the hallway and approaches Dr. House. They chat and laugh with one another; Cameron is nervous. She wishes she could hear what they're talking about.

"Dr. House," Thirteen says respectfully, nodding at the man.

"Has she cracked you yet?" he asks, smiling at Cameron through the class. He wags his fingers teasingly at her in a delicate wave.

Thirteen grins, crossing her arms across her chest. "You could say that."

House squints his eyes seriously at the intern, with a curious smile. "What mischief are you up to? You are a wily one aren't you?"

Thirteen smiles, shrugging as she re-renters the patient's room.

Cameron turns to look her straight in the eye for the first time in over an hour. "What was that all about?"

Thirteen walks past the doctor, her hand brushing against the woman's hip and across her backside, seemingly by accident but obviously not. "I was just telling Dr. House what a great instructor you are."

Cameron takes a deep breath and holds it until the intern's hand has stopped touching her. She smiles, though, flattered by the professional comment.

"And I requested to be under your command for the rest of my training," Thirteen says, her smile innocent but her eyes sly. Cameron swallows hard; she can feel sweat building on her brow. Oh boy.

"Oh, that's really great. And thank you." Cameron says; her voice betrays no emotion, though she's terrified inside. Things are already complicated; could it get worse?

Thirteen nods and bites down gently on her bottom lip, the doctor's undivided attention still upon her face. "Yeah. I think we can learn a lot from each other."
