"Ouch." Jane said again while watching the syringe go inside her arm.

After they got back from New York, Maura got deeply involved in trying to find out more about Jane's newly discovered ability. Although she didn't want to admit it to Jane, she was a little scared of what this ability could do and how it could affect Jane, who seemed oblivious to the danger. Not that she expected Jane to be scared, but instead of being at least a little bit preoccupied, the reality was the complete opposite.

"You know, you could have told me that you were planning on taking all my blood." Jane told her sarcastically.

Maura just hummed. "The special tests that I'm ordering require a high quantity of blood Jane, so stop being a baby and cooperate." she mocked her.

Jane just looked straight. "Was it like this for you?"

Maura looked curiously at her.

"I mean, after finding out that you were special." Jane said nervously. "Was it just like 'Oh, look at that I can see people's memories, hurray!'"

Maura smiled sweetly and Jane and gave her a small peck. "Yes and no. Of course I was excited about finding out that I had special abilities that others did not, but mostly I was curious about how it worked. I didn't know anyone else that also had them, and for a while I thought that I was the only one that did."

"But I still don't understand how mine works." Jane said embarrassed. "I barely know about this world and now I seem to be part of it. I'm scared."

Maura took her hand. "Well, Detective Smartypants, I think you have an advantage that most of us did not have. You have me." she said while smiling at Jane, who immediately smiled back.

"You are a very humble genius." Jane said sarcastically. "I bet it's very difficult to be you."

"Oh, you have no idea." Maura said without noticing the hint of sarcasm in Jane's comment. "But if you want I can try to explain to you my theory of how your ability works."

Jane nodded and stood straight, ready for what she expected to be a very long lecture.

"Well, in order for you to understand it better, you would need to know the exact etymology of the word replication. It comes from the Latin 'replicare', and it means 'the action of copying or reproducing something', which is exactly what you do when you touch someone." Maura said. "But I have also noticed that sometimes it doesn't even take that, just a stare or experiencing the ability of the person being performed on you, being enough for your mind to be able to recreate it and sometimes even improving the ability."

Jane just nodded. "But why didn't I feel it sooner?"

"Maybe because you never had an encounter with a creature before." Maura said absently. "Some people can live their whole life unaware of the existence of them because they never crossed paths."

"So that day when I chased down that terrible creature..."

"Your brain's natural instinct of survival developed your ability and made it become functional." Maura said. "Some abilities, such as mine, do not require of the intervention of a creature to function because they are created based on our experiences. Let's use me as an example." Maura continued while pointing at herself.

Jane smiled. "A great example."

Maura smiled back. "Physically I'm not a threat, and because of that I wouldn't be considered to be a predator in our ecosystem. But, because I do need traits to secure my survival, instead of being physically strong I went the complete opposite way, having intelligence instead of strong musculature. This can be argued by which side of our brain is more dominant, in my case being my left side the one that controls my actions the most. Left-side brain persons tend to be more logical and analytical, very good with numbers and reasoning." Maura said while pointing at herself. "But our side of the brain is not the sole part that determines why we develop different abilities. What is generally true with all humans is that our amygdala decides which memories it wants to restore and discard, which things to remember and forget or what things we want to obtain. After our amygdala chooses which memories to restore, our hypothalamus, based on the things that we learn thanks to our amygdala, selects on what things to focus. And this then gets transmitted to the rest of our organism thanks to our brain cells, which carry what we call the Myelin Sheath in our brain cells. Unlike normal humans, our brain cells are able to produce the quadruple quantity, which leads to our brain to expand in size, and this expansion in return, along with the influence of our emotions and fears, ends up creating the Chicondria. The Chicondria is basically the organelle responsible for the creation of abilities. Different Chicondria create different abilities, and in my case, because I was more logical and scientific, my Chicondria created an ability that took advantage of my knowledge, one that cannot be used for attack or defense, but for scientific inquiry."

Jane just looked at Maura, who was waiting for an answer. "Well, it seems you really thought about this." Jane said while smiling.

"I did." Maura said while sitting down again. "You clearly don't understand how unique your ability is Jane. To be able to copy others abilities is such a dangerous thing. It's like taking away a piece of a person's identity and using it against them."

"Is that what you thought when I made you see that memory?" Jane whispered quietly.

Maura made Jane look at her. "Of course not darling. When you touched me I felt the love that you feel for me, the care and concern that you have always shown to me since we met. Still, because our brain's most emotional parts are responsible for the creation of our abilities, they tend to always influence the way we experience and use them. With you, and every time you have come with me inside a memory, it's true that I have felt the usual darkness that I usually experience, but at the same time, there was a warmth and peace, which I'm sure comes from you and what we feel for each other." Maura said while smiling warmly at Jane.

Jane smiled back, but then a thought came back to her, something that had been bothering her. "Do you remember that time we saw Mephisto?"

Maura nodded.

"He manipulated the memory too, right? That's why he was able to directly speak and address us." Jane said.

Maura nodded again. "As soon as I saw what you did with the specter I suspected the same thing. He also has the ability of replication."

Jane fidgeted. "So that's why we felt the memory be so awful and full of hate." Jane said while grabbing Maura's hand, shaking at the memory. "It was because he manipulated it."

Maura nodded again. "It's the two sides of the token. While you bring warmth to the person's abilities you obtain, he brings darkness and hate."

"Do you think he knows?" Jane asked quietly. "Because if he doesn't then I want to keep it that way. Who knows, maybe keeping it a secret will give us the upper hand, which is why you will not let anyone else apart from us two see the results of those exams."

"And Korsak and Frost?" Maura said disapprovingly. She hated to keep secrets. "They are also part of the team."

"And we will tell them Maura, as soon as we confirm that the ability that I do have is replication." Jane said. "Or are you willing to assure us all that without a doubt I possess this ability?"

Maura looked at Jane and saw her smiling. She already knows how to drive me crazy, but instead of following her game she simply nodded and took the blood samples with her. "Because I can't compromise the results of the experiment, I will refrain from telling them to anyone, including you." Maura said while smiling back.

Jane's smile fell, realizing that she had been defeated at her own game. She got up and quickly went to hug Maura, who also smiled and smirked at her, moving around the room and squealing while Jane followed her. It didn't take long for Jane to catch her, and without any struggle she brought her close.

"We are in the middle of my office Jane!" Maura hushed while looking around. "What if someone decides to come here?"

"Well, are you expecting someone Dr. Isles?" Jane asked flirtingly. Maura closed her mouth, feeling suddenly blank. "You know, the fact that someone may come in makes all of this more exciting. Don't you agree?"

Maura squealed. "Yes."

Jane laughed. She lowered her hand and felt Maura accommodate herself. "Should I stop then?"

"No." Maura whispered while letting all her inhibitions go. She moved head and kissed Jane's neck.

"God, I will don't think I will ever get tired of this." both women said at the same time, which made them look at each other and laugh.

"Maybe we should refrain from saying the exact same thing at the exact same time in front of others." Jane said while bringing both of them to the comfort of Maura's couch. As soon as she sat down she yelped. "This is the most uncomfortable couch that I ever sat on."

Maura laughed. "This is an Eames Sofa Jane."

"So what? It is really uncomfortable and couches are supposed to be the complete opposite." Jane said while standing up. "There is no way we are going to be making out on that couch. My back won't take it."

Maura smiled and laid herself on the couch on purpose, making Jane open her eyes and stare deeply. "Really? Well that's very... inconvenient." Maura whispered the last part while taking her shoes off. "You see, I was in the mood of breaking the rules. With. You." she enunciated on purpose each word.

Jane ran back and kissed her deeply, humming her contentment. "The things I do for you." she mumbled before taking her boots and jacket. Maura was starting to remove her belt where her badge and weapon were, but when she felt Jane's phone vibrate she stopped.

"Ignore it." Jane said while grabbing Maura's shirt and popping the bottoms open. Maura held her breath when she felt the sudden chill of being exposed and she dropped Jane's phone, which started to vibrate again. Maura, completely focused on getting Jane's shirt also felt her phone vibrate, making Jane groan angrily against her chest. Maura smiled sadly and kissed the top of Jane's exposed chest.

"Dr. Isles." she said while kissing Jane's hand.

'Is Jane with you? I called her but she didn't answer.' Frost said.

"She is here." Maura simply answered while getting up and fixing herself. Jane followed and started to gather all her stuff.

'Maybe she forgot to switch from silence mode.' Frost added. 'We need you two to come as soon as possible to the conference room.'

"Do we have a new case?" Jane asked while taking Maura's phone and putting it on speaker mode.

'I'm afraid it's worse than that.' Frost said quietly. 'We got a video-call. From our couple's killer.'

Jane and Maura looked at each other. "We will be there in five minutes." Jane said while hanging up. "Listen Maura, whatever happens, know that I am right here with you. He knows who you are, which he will use to his advantage, Don't let him get to you."

Maura nodded while taking Jane's hand and making their way to the conference room. The walk there was short, and as soon as both women made it inside the room they saw Korsak deeply troubled and focusing on the screen. In it they saw a young man and woman sleeping peacefully. Jane realized right away what this meant; the creature was tainting them to act on impulse, to realize that there was nothing they could do to save those humans. He heard them get in and quickly smiled when he focused on Maura. Jane noticed this and immediately set herself in front of her, the creature's gaze changing to amusement.

"So good that you could finally join us Dr. Isles." he said while smiling. "And from what I see with a new friend. Tell me, who are you?"

"Keep trying creature." Jane spat angrily.

The creature laughed and again focused on Maura. "Did you open the present I left you at Beacon Hill? Wasn't it something else?"

Maura stayed quietly looking at the scream, no hint of having any emotion. "Was it strange to feel yourself being absorbed by darkness, almost every day, and still make it out of there unmarked?" he said while smiling softly. "I have seen you there Dr., walking right past me, and although you may convince yourself that you are doing it to help the dead then you are more than mistake. The reason you do it, and the reason I do, is because we enjoy it. We enjoy invading and feeling other people's emotions as if they were their own, unachievable for us because we are too logical. Although you may not like it, you have to be fully aware that you and I are not so different from each other."

Jane had heard the whole discussion, or monologue, between Maura and the creature. Although Maura was not showing it, she knew that deep inside she was getting close to her breaking point, her mind and logic being convinced little by little. Jane knew that she had to do something before this happened. She stood up and went to face Maura, shaking her and then turning around so she could face the camera.

"Listen to me freak creature." Jane hissed. "You may think yourself as very smart and cunning, that this is all a game that you are determined. Sadly for you, now I'm also playing this game, and believe me, I'm very competitive." she added while facing him. "If you don't believe me then go ahead and ask your friend with the green suit." Jane spat at him, making him show the smallest of reactions. He smiled.

"Perhaps I underestimated you. But don't worry, that never happens twice." he added while chuckling. "Although I would love to stay and keep talking to you, I'm unable to do so because duty calls." he added while looking at couple and walking towards them.

After the video call ended Jane quickly sat down and looked at Maura, who was breathing deeply. She saw Korsak angrily alert troupers to be on extreme vigilance, but they all knew that it would be too late for the couple. Still, after he hung up he approached the two women, and raising his eyes he waited. When none spoke he just sat down in front of them.

"Maura, you never told us about that case with the New York homicide department." he said silently. "And if I'm not mistaken, a case that had a connection to our killer"

"His name is Mephisto." Jane said while looking at him. "And yes, without us knowing, it turned out that Mephisto has been manipulating the memories from his victims and making us see what he wants us to see. All dead ends. Korsak simply nodded and angrily started to move around the room. "This creature is too experienced and complex. It will not make mistakes easily and will play us all until it gets what you want.

Maura nodded. "He is a replicant."

Frost and Korsak looked surprised at her. "How do you know this Maura?"

"Because of the things that he was saying, each of them can usually be felt with all the different powers, and physiologically speaking she was reacting purely based on that."

"Then we are more than screwed." Frost said. "If the creature keeps changing the memories when we will never know what is reality and what is a lie."

Jane nodded. "Then I guess it's a good thing that we have an ace under our sleeve."

Both them looked at Maura waiting for confirmation, but when they saw her just as surprised as they were they knew that she was not part of the plan.

Jane just huffed. "You have me."

P.d: In this chapter I introduced two new terms that will be key during the rest of the story. The first one was replicant, which is basically the ability to imitate and reproduce anything seen. Both Jane and Mephisto are replicants, and the reason why they are able to manipulate and change the abilities from whom they replicate it from is because they adapt it to their own situation and emotions. As Maura said to Jane, the way abilities react is unpredictable because they are mostly influenced by the feelings of the human, which means that abilities can repeat themselves between humans and creatures but still act differently. Because creatures also have abilities, Jane was able to replicate the abilities of the specter and use them against it while trying to save Maura.

The second important term, and that I invented, (trying to make it a little bit realistic) is the Chicondria, which is basically the organelle responsible for the creation of abilities. The Chicondria is created because of the uncommon high level of Myelin Sheath in the brain cells of both humans with abilities and creatures. This irregularity leads to the brain expanding, which in return allows the creation of the ability.

Another thing that I think would be good clearing is that Maura here has the connection with Mephisto, Jane being the newcomer and protector of Maura. The reason I did this is because I kept remembering that conversation that Maura and Hoyt had on 1x08, and how he said that they were alike. I thought it would be nice to see how there are different types of darkness (the dangerous ones like Mephisto's and the ones that isolate you from the world like Maura's).
