Temperance Brennan ran her fingers through her hair and sat back with a sigh. She had been writing for what felt like hours and could feel her muscles seizing up.

Cases had been pretty slow since the week before last and she had resigned herself to cataloguing the remains of Iron Age skeletons. She was itching to have another case. To be out in the field with Booth. To interview suspects with him and try to figure out motives. To stay up late into the night with him, tossing around ideas. She would also enjoy working with the rest of the team too. Of course.

Now that she had finally stopped, she started wondering vaguely what time it was. The growling of her stomach seemed eager to inform her that it was well past feeding time. Booth would kill her.

Almost as if reading her thoughts, Seeley Booth strode into her office. Hastily placing a hand over her stomach, as though to quench the noise, she raised an eyebrow at him.

"What do you want, Booth?"

He placed a hand on his heart and dropped his head, as though defeated. "Now is that any way to greet your favourite F.B.I. agent?"

Grinning broadly at him she chirped, "You've been eating!"

His brow furrowed in confusion, he nodded. "Yeah, I just had the most amazing lunch…cheese everywhere…and I thought I'd come in and see if you've eaten, coz I figured you hadn't and...how did you know I've eaten?"

She flashed him her most superior look, stood up and leaned towards him, placing her hands flat on her desk as she did so. "The little piece of lettuce you've got caught in your teeth was a pretty good indicator."

He groaned inwardly and unconsciously copied her movements until both of them were leaning across the desk from either side. "Where is it?" He cocked his head to the side and grinned at her.

She bared her teeth at him and tapped her two front teeth with her index finger. He exposed his own teeth and indicated the ones in question. She nodded.

Neither of them moved from their positions as Booth ran his nail between his teeth.

Brennan giggled. "No, not der. Der!"

"Der?"

Both were having trouble understanding the other through clenched teeth, but that made it all the more amusing. After a number of minutes, and quite a few giggling fits on Brennan's part, the lettuce was removed.

He leaned in a little bit more and flashed his charm smile at her, still leaving all of his teeth exposed. Brennan attempted to reciprocate the action but was having trouble doing so as she found the whole exercise quite humorous.

The sound of someone clearing their throat made them both turn towards the door, still grinning like Chesire cats. Angela stood in the doorway, a thoroughly bemused expression on her face.

"Am I interrupting something? Are you guys high?"

"Nope. Not at all. I was just asking Bones out to lunch, that's all."

Snapping out of her trance, Brennan frowned at him. "You just ate. You can't have two lunches."

Already making his way out of the door and past a chuckling Angela, Booth called over his shoulder. "Course I can Bones. Just watch me."

Shaking her head slightly, though whether it was at herself or Booth she wasn't sure, Brennan rounded her desk and jogged after him, muttering to herself.
