Sweet Fifteens -Prologue

Night was falling over the peaceful town of Sacramento when Lisbon eventually decided to turn her computer off. On the left side of her desk, a file filled with information on the latest case was still opened. She picked it up, putting it in her bag before preparing to leave the office. She turned off the lights and stepped out, checking from the corner of the eye the couch where Jane usually laid. Tonight it was empty. Probably because he went to visit that mad scientist again.

The petite agent shook her head in amusement, thinking that similar personalities indeed drew people together. Michel Kausner was some kind of a strange fellow. A small, energetic brown-haired man with sparkling and teasing black eyes; always wearing that weird white jacket reserved for doctors, those thin glasses and that crazy smirk on his face that not even a slap or a punch could erase. His tea addiction was the first point he and Jane had in common. He had also lost his family, in a train accident, and since then had lost himself in his creativity and hadn't stopped building useless inventions. For some reason, he and Jane hit it off right away.

The only dark spot in their new friendship was the way they met. That case was also the very reason why Lisbon couldn't really look at Michel Kausner without shivering with uneasiness. Not only his so-called inventions gave her the creeps, but the way he sometimes glanced warily at her, as if afraid she was going to hit him or something bothered her a little. Though she couldn't remember all of it, she had read the reports –exceptionally written by Jane himself and supervised by Cho. There wasn't much written, but the few elements the consultant had faithfully described about her behaviour made her blush in embarrassment. 'Out of character' were the exact words, as well as 'insulting', 'nosy' and 'impertinent'. Perhaps it was not a bad thing she didn't remember.

When she eventually got home, she plunged in a hot bubbled bath and closed her eyes.

Thinking of it, Jane never really told her every single detail of the case. She knew that after some… incident she couldn't remember, she hadn't acted as usual. The fearful sided glances or smirks people threw her in the corridors, Hightower biting her lip as if holding back unpleasant comments and the wariness of her colleagues when she stood near the coffee machine were enough to confirm that information. And while she asked why her colleagues acted extra-cautiously around her, they would never reply directly to her. And that was so…unnerving!

"Lisbon!" a familiar voice pulled her out of her reverie.

Her eyes snapped open as she realized Jane was in her house and probably looking for her. Without thinking twice, she stood in her bathtub and stretched her arm to grab the closest towel as the handle twisted and the door opened wide, leaving her in full view to her intruder.

"JANE!" she yelled, horrified, grabbing the towel and covering herself. "GET OUT OF MY BATHROOM!"

The consultant barely blinked and blurted with a wink:

"I've already seen you naked you know… and you weren't complaining."

Her jaw hung low in disbelief. He seemed to be completely serious. Did he really saw her… bare of clothing? And what did he mean by 'not complaining'?

"You really don't remember" Jane added with a huge grin.

Lisbon hated it when she didn't know what to expect from him, because lately, her memory had a hard time recalling everything… or anything at all for the matter. She stepped out of her bathtub without stopping glaring at him.

"Wait for me in the bedroom or the living room while I change, then I'll take care of you" she hissed between her teeth. He raised his eyebrows.

"You're leaving me the choice of the place for making out now? I thought you preferred uh… 'a good fu** in the shower' to quote your own words."

Her cheeks turned a deeper shade of red. The consultant figured it would be best to escape her wrath now and, ducking the toothbrush flying at his head and exiting the bathroom as fast as he could. While Lisbon put her jersey and pyjama pants, she tried to chase away the nagging feeling that he wasn't lying. Okay, she admitted that having sex in the shower was her fantasy… but no way could she have confessed that to Jane of all people. Even less make a move on him. But then, she didn't remember a thing…

Lisbon growled and shook her head. This had to end, and quick! She was going to tear information out of her consultant since according to the team; Jane never left her side the whole time. Now presentable, she stormed out of her bathroom and checked around for his presence. Not in the bedroom, so she headed to the living room. As she expected, he was sitting on her couch, waiting patiently for her arrival. She didn't wait any longer, walked up to him and blurted immediately:

"Okay Jane, now you are going to tell me what happened or I am going to kick you hard where it hurts and torture you slowly until you confess. I want to know what happened during the period I lost my memory. The doctor said I'd recover with time, but I want answers now!"

The blond man's grin faltered immediately and he cleared his throat. Lisbon was surprised to realize he was slightly embarrassed.

"Are you sure you want to know? Because you are going to avoid me for days afterwards."

That statement stirred her curiosity. She sat in the couch facing him and crossed her arms, waiting for an answer. Jane cleared his throat again and adopted the same posture she had.

"What do you last remember?"

Lisbon frowned and forced her brain back to the events happening just before the black hole in her mind.

"We got a call from Hightower who wanted us on a new case… A guy named Jonathan O'Brian was found murdered in his living room. It appeared he had been poisoned by some gas… and we found out one of his friends, or acquaintances, often used that kind of product for do-it-yourself jobs… Michel Kausner" she added. That was the first time the consultant and the scientist met. "I drove to his house, with you… but then it's kind of blurry."

Jane nodded absentmindedly.

"Okay, then I'll start from there…"
