Sweet Fifteens -4

"Remind me why you chose to bring me to the library of all places?"

Jane sighed in frustration, wondering what he had done to deserve such a fate. Lisbon's mood had not improved since the previous day –especially with Kausner occupying the guest room, and he was very much looking forward to the moment she would be a bit less bitchy and… teenager-like. The girl had woken up far too late to do anything worth for the day, so he had opted first for the library, since the Lisbon he knew enjoyed reading. He should have remembered she wasn't exactly the same. A completely new personality was to be studied, including the swinging moods of the typical teenager.

"There will be days where you won't be able to move around a lot" he replied as-a-matter-of-fact. "You will need a few distractions."

Lisbon threw him a dubious look before searching half-heartedly through the shelves for anything interesting in her eyes. Jane sighed in relief and looked around in turn. The library was bigger than he thought, and hopefully the teenager would find something she would like. Half an hour later, she came back with a few books.

"I got three" she muttered. "Can we just go now?"

They headed back home with an unsatisfied Jane with his performance as a mind-reader. Teenage Lisbon was hard to anticipate and it unnerved him. Usually, he had no problem with her keeping him on his toes, but now that she was younger…

"Ok, what do you want to do now?" he asked, trying to anticipate in his mind her answer. And once again, she surprised him by answering with nonchalance:

"I spotted a few old movies next to the TV. I'm good for it."

That day and the next, they only went out for a quick walk and buying junk food to watch the movies. Lisbon was not in the mood for going out and her mind was set straight on watching every DVD in the closet. It didn't surprise him when she eventually fell asleep on the couch, mouth slightly opened and drooling.

-SF-

The following day was Cho's turn and though Jane trusted the Asian man, it bothered him to leave Lisbon out of his sight. The girl seemed rather reluctant to leave with the stoic agent, but followed him nevertheless, clearing expressing her tiredness of being stuck with the blond all the time. For lack of a better activity, Jane just went to work. By chance, a new case arrived: murder on an airplane base. Unfortunately, he couldn't focus on anything properly; Lisbon wouldn't stop invading his thoughts. If tact and politeness were absolutely not his priorities before, they were even less important now.

That day marked the moment Hightower eventually realised that, despite her initial thoughts; Lisbon did handle Jane better than she thought. Without her (or Cho, for the matter), none of the team members had the authority to control him. She called him back to the office immediately and gave Jane his next two weeks off, the period which Lisbon had first been potentially declared on vacations.

But when Jane came back at the apartment that afternoon, he found out that pissing off Hightower was not such a bright idea. Now he had nothing to do –Kausner was gone for the day too- and he had absolutely no clue where Cho and Lisbon were. Or rather, he had a few ideas, but didn't want to join them. Cho would certainly drag Lisbon for some sportive activities and he was not the kind of guy to wander in health centres. Baseball or hiking certainly; he could perfectly picture the teenager manipulating a bat and delivering her frustrated impulses against a ball…

He ended up walking around the neighbourhood, making acquaintance with Lisbon's neighbours and checking out the places he hadn't been through yet, filling the 'Lisbon file' in his head. At nightfall, he was back on Lisbon's couch, arms crossed behind his head, thinking of what to do for dinner. The clock struck nine when the door eventually opened. He stood up from the couch and headed towards the entrance door. The teenager was obviously exhausted but very pleased with her day. Despite her heavy panting and circles under her eyes, her smile spoke volumes.

"The dinner's not ready?" she said as a greeting. "God I'm starving! Kim really wanted to exhaust me… we walked for hours and miles and it was so bright and sunny!"

Jane chuckled when he heard the nickname.

"Well I didn't know exactly when you would be back and what you wanted."

"Rice or noodles would be fine" she replied with a thankful glance. "I swear Kim's no fun but he hits better than I do… never missed the ball…"

So hiking and baseball, like he expected.

"Say Patrick, I'm completely out… can I lay in the living room while you cook?"

The blond man nodded and smirked at the sight of her retreating form. She was walking awkwardly already and on the verge of falling… He made a mental note to thank Cho later. Exhausted teenager Lisbon meant cooperation, and that was exactly what he needed for future collaboration.

-SF-

The next day, firmly decided he was not going to be 'boring' this time, he asked her if anything interested her for the day. After a few moments of hesitation, Lisbon declared she wanted to go to the cinema and they planned to go early in the afternoon. The weather was quite warm and shiny, so it was decided they would go to the movie theatre by foot, crossing by the park. They were walking in a peaceful silence when

suddenly, Lisbon turned toward him and asked:

"Hey Jane, can I have a few bucks? There's an ice-cream seller over there and since we didn't really have desert…"

"Uh oh sure. I'll go with you."

She rolled her eyes and crossed her arms.

"Please I can still buy an ice-cream! You just… sit there" she pointed a bench not far "and I'll be back okay?"

Jane sighed and pulled out a buck of ten dollars from his vest pocket and handed it to her.

"Go get that chocolate cinnamon thing."

Grinning widely, she thanked him, snapped the bill and happily toddled away. Jane sighed in relief and headed towards the bench instead of standing up like an idiot. So far things had gone okay. He was a little bit scared she would be mad that Rigsby did not take his turn –for she seemed eager to try a few tricks on him; but apparently the hiking had more or less killed her aggressive moods. He suddenly checked his watch and realised she had been gone for about fifteen minutes. And he knew it did not take so long to buy an ice-cream. Unless the seller had been assaulted by a group of kids, of course. Five minutes later, he decided he had waited enough and headed in the direction he had seen her disappear.

He was not very pleased to spot her in the afar, smiling flirtatiously to a boy in his eighteens. The young man was ogling her appreciatively and obviously trying to get a little more from this conversation. Her number certainly and already planning a future date or something that would lead them both to somewhere private… Jane shook his head, scolding himself for reading the young man's body language. He decided he should intervene, screw it if Lisbon wasn't pleased.

"Teresa if you are done let's go, we are running late!"

The two teenagers raised their head in unison and stared at him, Lisbon obviously unsatisfied with his interruption. Even if he was at some distance, Jane could hear their conversation:

"Who's that guy?" the young man asked.

"He's…" Lisbon started to reply, and he could hear the budding panic in her voice, as she searched for a reasonable position in her social life. "…a friend of my parents. Sort of."

The guy stared alternatively at the consultant, then at the teen, and back at the blond man again.

"Teresa!" Jane called out again, making sure he was sounding impatient. Now, he loved the desperate expression on her face. The guy seemed to have second thoughts about the teenager, and Jane was very, very happy about it.

"You're sure you're not jumping him or something? Cause he looks like he's going to kill me if I speak a word more."

Her jaw fell in shock and she slapped him. The young man stared at her completely stunned.

"Calling me whore, asshole!" she huffed and walked away, back to Jane. She looked so furious he decided it was a wise thing to remain silent for the time being.

"And you; did you really need to step in?" she growled, crossing his eyes with a death glare. "We were just talking, not making out!"

"But you wanted to see that movie…" he replied innocently, pointing his watch indicating ten to two. "And if we don't hurry…"

"Oh I get it, you say you want to let me do what I want for a few days, but in fact you're just trying to nanny me right? What do you think, I'm going to run away? You know what, forget the movie! I'm going back home!"

Jane shrugged and followed her as she stormed through the park. According to his little experience with teenagers, Lisbon was likely going to lock herself in her room all afternoon and only go out to snatch something to eat before whining her misery to her pillow. He took his sweet time though, knowing the teen would still have to wait for him at the entrance door. He was the one with the keys after all.

-SF-

The fifth day didn't start on its best. After little sleep and bad nightmares, Jane went down the kitchen only to find a piece of paper with Kausner's handwriting, telling he and Lisbon were going to the shopping centre. When he tried to call, neither would answer. The only way he managed to kill time was to jump at the office and bug a few colleagues.

He was back at two pm, kicked out by Hightower who did not want him and a suspect in the same room, for his tension made his teasing and mocking even worse to bear.

It wasn't until the clock struck seven pm that the two missing persons opened the door. Kausner was the one he came across first, and Jane did not like at all the guilty expression on his face. Sensing he was about to receive dreadful news, the blond man breathed deeply in and out and asked as calmly as he could:

"Okay, what happened?"

The inventor bit his lower lip and muttered:

"Lisbon… uh Lisbon eluded me when we arrived. I spent the rest of the day looking for her and she was already like that when I found her."

Jane stepped pass him and froze in the hallway. At first, relief dawn upon him as the teenager was contently undoing her shoes, whistling a happy tune. It was when she turned her head towards him that he nearly had a heart attack.

Lisbon had gotten piercings. Two piercings. One on her left nasal, and another one of her right eyebrow. And his face fell completely when he realised she also had bright red locks in her hair. Where did those came from?

"Good evening Jane" she greeted cheerfully.

"You got piercings? And… and what happened to your hair?"

"Yups" she confirmed. "They look good don't you think?" when he didn't reply, she went on, catching a wild flashy red lock between her fingers: "And I decided I'd look better with these. It was love at first sight when I saw them in the window. They were so cool I couldn't resist! And I'd show you my tattoo but I'm not sure it's dry yet."

"T… tattoo? You got a tattoo?"

Once again, he was rewarded by a huge provoking grin.

"See? I asked for a snake" she asked, turning her back to him and pointing her shoulder blade. Under the clothing, a square-like form could be distinguished. Certainly the paper covering the still fresh drawing marking her skin.

Oh dear, when Lisbon would be back to her older self, she was so going to kill him.

When she passed next to him, she let a credit card on the closet next to him. He blinked at it, recognizing his own.

"Giving it back to you" she added in a fake-sweet tone. "Don't worry, you still have money on your bank account."

And on those words, she headed for her bedroom, humming, and leaving behind a low-jawed Jane, staring at her in disbelief. Forget older Lisbon's reprimand; he was going to learn to not underestimate her from NOW on. A soft noise reminded him he wasn't alone in the room. He glared at Kausner nastily.

"Now, you are getting out of here before I get very, very angry."

"But…"

"I don't care about your experiments and such, but if you ever put one toe back in this house, I swear I am going to chop you into pieces and feed you to your neighbour's cat."

The inventor bit his lower lip but eventually raised his hands.

"It's okay, I'll leave. But can you call me if anything goes wrong?" Jane nodded, but still glared. "Okay I got it. See you later."

The inventor didn't take long to pack up his things and step out the apartment. As the door shut, Jane spotted the teenager at the end of the corridor.

"The creep's gone?" Lisbon asked, tilting her head on the side. Jane nodded determinedly.

"I'm not going to let an incapable keep an eye on you. Why did you wander off like that anyway? It could have been dangerous!"

"Sorry" the teen muttered, looking away. "I'll go make dinner?"

Her way of apologizing, he supposed. He sighed deeply and waved at her for dismissal.

"Okay; I'm going to call Van Pelt. Do you know how to cook something without burning it?"

She huffed at his sentence with a shrug, taking offence in his little trust. Half an hour later, while they were eating reasonably cooked noodles with tomato sauce and beef, someone rang at the door. Lisbon glanced at the door but Jane stood up before she could get up. When he opened, he was greeted by the grumpy face of a redhead. Obviously, Van Pelt was not happy to be disturbed late at night.

"Thank you for coming, and sorry for the bother" he said apologetically. "I had a hard time handling her and since Kausner was no help…"

The teenager popped behind them and when Van Pelt caught sight of her physical change, she smirked amusingly. And Jane had the nagging feeling he had missed something.

"You are a manipulative one" the redhead said knowingly. "But I swear you won't get me kicked out so easily."

The mentalist widened his eyes in realisation while Lisbon smiled innocently, toying with her pendant.

"Don't know what you're talking about, Miss Van Pelt."

He had walked straight into that one!

Thanks for reading so far! :D
