Hello! *takes another bite of her tomato salad* Yes, I got tomatoes for the first chapter *winks and waves to the man selling tomatoes outside the window*, but don't worry, they were not about the story being bad or anything (thank god), they were just… not important for the plot. I want to thank you for your support, it's great that you have liked it and that you want to read more about this crazy idea of mine (you know, just the idea… sadly nothing more than that). Also I'm so sorry for delaying this more than expected, I wasn't feeling at all well last week and an aching head is not something I can tolerate while writing in front of a bright screen, I talked to my (doctor) father, he gave me medicine, I'm better now (just so you know, no worries).

With that said let's go to the story, there are a few notes I should make: first italics inside dialog are thoughts, I'm sure I don't need to tell you why they're appearing there. Second I'm just getting used to this writing style and English is not my first language so please forgive my mistakes, I try not to have them, but I'm only human (also I don't have a beta). Third you must know that I have nothing against any character of the series, so there will be no harassment to any of them from my part. Hope you like it, read, enjoy and if you want to leave a comment it will be highly appreciated (tomatoes are welcome too).

2.- Complications

Sheldon's eyes narrowed in suspicion, there was something really strange going on. He ran a hand through his hair, and to his surprise Penny did too, her long blonde hair getting messy by the action. She was looking at him with a perfect reflection of what he supposed was his own expression. She then moved facing the living room, and he did too, they both moved one step. They shared another concerned look.

In an attempt to act before the other Sheldon crouched… only to be mirrored by Penny, suddenly feeling the urge to laugh he smiled, Penny giggled. In tandem they stood up again and walked towards the couch, facing each other Sheldon sat down on his spot and Penny in the space right next to him.

"So…" he said, trying to address the problem at hand. "Do you think we should go to the hospital or just for a quick check up at the clinic?"

"I don't know Sheldon. I don't think it's a good idea" Sheldon stood up, this time Penny stayed in her seat on the couch.

"Let's analyze the facts. On Friday night we were both connected to some electrodes, wired to a brain scanner and a computer, the lights went off and then they came on again striking us. We both had also swallowed a pair of pills that Bernadette provided, and I assume those were experimental drugs, that allowed our brain waves to synchronize, thus helping them with their 'study'." He said walking around the couch and running a hand over his mouth… Wait… there was something important that wasn't happening there… "Penny. Are you hearing my voice? Where you listening to what I said?" He asked, this time feeling panic run through his veins.

"Of course I did. This is affecting us both; I want to know what happened." Sheldon's heart beat increased, feeling his hands starting to shake he walked once again to his place on the couch.

"Penny, look at me" He said placing both hands over his mouth, the blonde looked at him with a weird expression, she also looked nervous, but Sheldon didn't want to make further deductions. "Can you still hear what I'm saying?" He asked, his hands still pressed to his mouth, his eyes wide. Penny's expression told him every thing he needed to know, his breathing became ragged.

"How…? How can I hear you with your hands over your mouth? Sheldon what's happening?" Asked Penny's voice in his head – yes, his head, she hadn't opened her mouth either-, he shook his head, not sure of how to react to this discovery.

"Let's think this through. Amy and Bernadette gave us those drugs to study our brain waves as friends, since it involved the group and we've been friends for a while it's not difficult to have some similar reactions when we're together. Now, the electrodes were stimulating our brain in a subtle way, pulsing every now and then. The lightning on the other hand turned off all the light.; if I am not mistaken, the brain scanner resets itself every time its needed, so that the operator can place specifications, the charge coming from the power up when the light came back made it give us a stronger charge than intended." Penny moved her hands and fingers, and approached one finger to his arm, feeling the static that made Sheldon's arm hairs to stand, his eyes focused on that and when Penny touched him a spark made them jump.

"Ok, let's say I understand. What does that mean?" She asked looking at him.

"Seems like our brains are connected with each other."

"Do you think it's going to pass? I mean… We're not going to stay like this forever, are we?" Sheldon looked to the floor, rubbing his arm where the static spark had been.

"I don't know Penny. It's been the whole weekend. By now all the static should be gone; we shouldn't be having any secondary effects to start with because the drugs probably were not having effects on Saturday morning. And obviously we shouldn't be able to do what we are doing right now." He looked at her again.

"Oh, I'm sure we shouldn't. But what is this? How was it called… telecomunications… teletrans… ?"

"Telepathy. The ability to communicate thoughts without speaking or writing. Speaking... Sorry, thinking of which, we should really visit a doctor, let somebody know about this…"

Penny shrugged in her place. "Maybe, but don't you think they'll take us for studies? I don't think I want to spend weeks, secluded in a hospital room, with all the needles, probably the blood and all the things they are going to try to experiment on us. Can't you do the study? I mean, I trust you, I know you wouldn't make me go through a painful or uncomfortable study, and I'm sure this is going to be a huge discovery. The first real prove of telepathic communication. Do you really want someone else to do it? Think about how all the experiments could damage your brain." She knew she was manipulating this, but if they're brains were really connected then Sheldon knew it already, and she was terrified of what that could mean if someone else found out about it. The physicist looked at her, his knowing gaze telling her that he could perceive her intentions, but her argument had worried him a bit.

"We still need to learn to control this. We are highly synchronized; obviously you noticed our coordinated movements when we were not 'talking' like this. So let's try to act like individuals and act normal, or this is going to be difficult to manage at work…" Penny nodded and opened her mouth.

"I should head back to my apartment then…" She said, and stood up, rolling her eyes when Sheldon also stood up with a sigh. With a huge effort Sheldon sat down again, crossing his arms over his chest. Penny turned around, also making a conscious effort to walk away.

"Have any of you received a call from Sheldon?" Asked Leonard carrying his tray towards the table where Howard and Raj were waiting for him.

"Not really" said Howard. "You don't think something really serious happened to them that night, do you? Because Berny has been really worried, she fears that Sheldon complains to the company and they fire her; she was also afraid of them going to the doctor, that kind of experiments, unsupervised and everything tend to give problems, she thought it wasn't a good idea."

"I know. I tried to tell them that maybe the best was to ask Amy and Bernadette to check on them, but this morning when Amy called Sheldon made it clear that the banishment was still in place. I could only hope that Sheldon's germ phobia and his tendency to exaggerate medical problems keeps them out of the actual hospital or make the doctor think he's being dramatic again." Said Leonard, starting to eat his sandwich; Howard and Raj shared a glance and nodded.

"Did Amy say something about Penny?" Asked Raj taking a sip of his soda. "We know how Sheldon tends to exaggerate every thing, but she's not one to complain when something is wrong. I've known her for years and I can hardly remember more than two times when it was obvious she was sick. Did any of them have symptoms to worry about?"

Leonard thought for a moment on the weird interaction between Penny and Sheldon that morning, the weirdest part of it had been when he had asked Penny if she could take him to the doctor and both Sheldon and Penny had answered at the same time; he thought it had been a coincidence; neither of them seemed to have noticed. However there was awkwardness, something that hardly ever happened with them, if anything Penny was Sheldon's best female friend, maybe there was something… nah that would never happen.

He shook his head. "Other than Sheldon predicting when Penny was going to knock on the door (you know, Vulcan hearing and all) and they way they both said something at the same time, nothing really extraordinary or to worry about. At least not a medical condition that the girls should worry about."

"They said something at the same time?" Asked Howard.

"Yes, but that was all, I was just asking Penny I she would find it troublesome to take Sheldon to the doctor and they answered at the same time, but you know Sheldon, even if it's troublesome, he thinks people is still going to take him wherever he wants, he just answered with her as a reflex."

The other two scientists nodded and continued with their lunch, the conversation soon moved to other topics.

Sheldon was on the edge of insanity, he was in front of his board, ready to solve yet another mystery of the universe when it started…

…the beat goes on and on and on and on and… Boom, clap…

He couldn't hear it, it was actually stunning the silence around him, and she probably had the music in the level he had told her to put her music so that it could only be heard in her apartment. Still, she was singing it! He could feel it, the urge to start repeating those unimaginative lyrics over and over again, couldn't she stop?

...make me feel good …

He rubbed his temples with his hands, trying to concentrate in the equations in the board before him. The sound of the music in his head started to lose volume, the numbers becoming clear, and then he started writing, enjoying the easy way his brain was solving the problem, one number after another, his mind also presenting him with a mental visualization of what he had pictured the universe to be in his mind. He filled the board in what seemed to be just a few minutes… And then he lifted his head, feeling how the gravity threatened to pull him to the floor.

He lifted his arm and knocked on the board… Sheldon. He turned around, his hand knocking into the air again… Sheldon! He capped his marker and walked towards the door, where the real knocking had continued… Sheldon!

He opened the door, Penny was on the other side, she had tied her hair in a ponytail, but somehow it was now all messy and some strands of hair were falling over her face. She lifted a notebook and pointed at it.

"Can you explain, what is this?" Even her thoughts sounded angry.

"It seems to be a notebook, full of numbers and calculations." He grabbed the notebook and scanned the numbers. "They look difficult for someone with your education level, why…" Then he noticed… "These are the same calculations I've just made on my board"

"I know that. I was trying to write the lyrics of a song down on my 'lyrics notebook', when suddenly my mind was full of numbers, and I couldn't stop writing. Can't you do your things on your own, why do I have to do this if you're the smart one here?"

"It's not my fault, and FYI I was listening to that hideous song that you were trying to write down, only Lord knows why, and I couldn't focus on my work. How am I supposed to unravel the mysteries of the universe with those inane lyrics repeating in the back of my head?"

They both looked at each other with a frown, then they both sighed, Sheldon moved to the side and let Penny in. She walked towards the couch and dropped herself over the middle seat. Sheldon walked back to his board and made a second check on Penny's notebook and his own notes on the board.

"This is going to be a hell of a problem…" thought Penny clutching her head in her hands and shaking her head. Sheldon looked at her, before answering.

"Well, as you pointed out a while ago it wouldn't be wise to share this with the world; I don't even think is a good idea to tell the others." He said, his voice resonating for the first time in the room, Penny looked at him with narrowed eyes she had probably heard his voice like an echo or something, both in her head and with her ears.

"How did you do that?... oh, no, come to think about it, it's kinda obvious." Penny then opened her mouth to start talking "Well at least this time there was no need for us to repeat what the other said" She leaned back on the couch, relaxing her body a bit. It was in that moment, just after hearing Penny speak in with her mind and mouth at the same time, when in Sheldon's mind something completely different happened…

… what a nightmare… please let this finish soon… No. Privacy. At. All. … it could help us understand the others Penny… no, please, no, I don't like this…

He blinked and shook his head to regain focus. Interesting…

"What?" asked Penny, obviously having heard that last thought in his head.

"Other than noticing that you in fact think before talking, I'd say I just heard a variety of thoughts passing through your head…"

"Other thoughts?"

"Yes. Thanks to that, I have and idea of how much you really don't like this connection. It's not my favorite thing either, but there's no much we can do about it right now. Oh, and somehow I think there was a memory there, but you added a few words to what Bernadette told us that day… You're memory of her voice is very accurate."

"Wait you heard that? … Absolutely no privacy…"

"Yes. And that part about lack of privacy too."

This time Penny's face turned angry, and she jumped to her feet.

"You shouldn't be angry with me! This is not my fault!"

"I know it's not your fault. And as much as I want to be angry with Berny and Amy I can't either! I refuse to blame this on them!"

"But…"

"No, you listen to me! Those thoughts of yours that are blaming Amy and Bernadette as if they were the ones who send that lightning on that specific moment are wrong! They had nothing to do with the lightning, or the electric shock! They can't control nature! It wasn't something planned, they had already made tests in a controlled environment before, what happened to us was an accident. So, stop blaming them and listing all those facts in your mind, it's annoying and stressing and… and…"

"Penny?..."

Sheldon barely had time to catch her before the blonde passed out; scared he laid her over the couch. What had just happened? Ok, ok… calm down Cooper. Think. Apparently she had been hearing to his background thoughts as well, and that was what had made her angry. Thus resulting in her talking about something that he was just considering, also the listing of facts about their situation… Hey, his brain really worked in a very different way! He should be careful in the future; Penny was not used to manage all that information at once, or all the processes his mind was capable of doing while he was thinking.

They had been able to act individually – at least for a while – in their respective apartments, it would be safer if he did 'heavy brain work' away from her… Not really difficult as their job places were a good distance away from the other, but… She was probably right about Amy and Bernadette; he should call them and explain… No, but what if they started doing their own experiments on them… Maybe just call them and lift the banishment… Raj would say that he had trust issues… Amy was probably hurt by the way he had reacted… … Great, his own mind was getting messy. Was this part of the side effects? What else should they expect?

Making sure that Penny would be comfortable when she wake up, he made his way to the kitchen, filling a glass with water and taking a pair of aspirins from the first aid kit. If he was right she was going to have a terrible headache. After placing them safely on the coffee table he took his laptop and started working. This was going to need some serious research.

Leonard, Raj and Howard arrived a few hours later, the three scientists worried of what they were going to find on the other side of the door.

"Maybe he has already taken Penny as his personal slave and the poor is now just fighting the urge to kill him" said Howard chuckling a bit after the last part of his sentence.

"It could have just been something temporal, nothing to worry about; they're probably watching Indiana Jones for the hundredth time" said Leonard trying to be reasonable.

"I don't want to make guesses. Let's find out!" said Raj excited.

During the day different theories had been discussed about the situation between their friends, at first it was with concern and a bit of fear, but at some point it had turned to "what if's" and from there the possible results of the experimentation had took them from sci-fi to supernatural ideas.

Trying to hide his curiosity Leonard opened the door, only to find Sheldon typing furiously at his laptop, and Penny snoring on the couch. There were a couple of boards full of numbers and notes, but somehow they seemed to have been forgotten.

"So much for a mistery..." said Raj disappointed. He and Howard made their way to the kitchen and helped themselves to some water. Leonard however approached Penny on the couch and watched her sleep.

"You're such a beautiful woman…" he whispered so that the others couldn't hear him, taking a loose strand of her hair behind her ear. "Like a fairy tail princess…"

"Don't!" came Sheldon's voice from his place in front of his computer, Leonard lifted his head and watched him, not sure of why he had said that. "Don't talk to Penny like that, especially not right now. I'm working!"

"And how is it me talking to Penny disturbing your work?" He asked a bit annoyed.

"It just does" said Sheldon hiding a visible tick when he said that.

Leonard narrowed his eyes, but didn't want to argue with him right now, so he jumped to the next item on his "to do" list.

"Did you have any trouble today? Are you both alright? ... How long has she been asleep?" He said a little more concerned now with his last question.

Sheldon jumped out of his chair, checking his watch. He pressed his lips together before looking around, by now Howard and Raj were also looking at him with worried faces.

"About two hours… To answer your previous questions, we had no major troubles today and until just a moment ago I was sure we both were fine…"

The four men in the room looked expectantly at Penny, who in that moment started to move, making them sigh with relief at the same time. She stretched up and smiled sleepily at them for a second… Then she opened her eyes wider and muttered a nervous 'hello?'

"Aspirins and water on the table. They know nothing, act normal…" thought Sheldon quickly trying to keep the scene casual in spite of his raising panic… which to his surprise was shared with Penny, if the way she was looking at him was anything to go by.

She nodded a bit, placing a cheerful smile again on her lips and then reached for the water.

"Hi, guys! How was your day at work? … Sorry Sheldon I asked for the aspirins and then fall asleep before you brought them…" Leonard looked from Penny to Sheldon, but if he suspected something he didn't say.

"Is it a headache the only remaining side effect Penny?" asked Howard, his worry for Bernadette was palpable even if he hadn't mentioned it.

"Oh, this one was actually caused by something different. Sheldon and I discussed it, and we don't have any other symptom, so we decided not to visit the doctor unless completely necessary." Howard looked at Sheldon. For a moment he felt a bit nervous because although they had decided not to visit the doctor, there was a very interesting symptom still manifesting itself on them, and what he was about to say would be a half truth, he was probably going to have a tick and they'll know it was a lie.

"It's true; during the whole morning we didn't show or suffered from any distressing symptoms. I'd say we don't need to see a doctor, at least not unless urgent medical assistance was required" he said trying to behave and stay as calm as possible, his friends looked at him for a few seconds, the longest 3 seconds of his life.

On the couch Penny's right eye twitched and closed against her will… a tick… and then they both sighed with relief… the others didn't seem to have noticed that, or Penny's reaction to Sheldon lying… Her voice reached his head and hi smiled.

"This is going to be terribly complicated"

Thanks for reading to you all. I'm already working on next chapter, it'll be up in a week or so, be patient. Salads are part of a healthy diet (not that I'm asking for more tomatoes, just so you know I don't mind them at all), but chocolates are my favorite dessert =D.
