Sam signed up for something before even realizing what he was doing.

Castiel leads Sam to one other room in his apartment which has a lot of robots, computers and technics which Sam has no idea what they are. Castiel turns on all the system and sees Sam's concern. He places hand on his forearm and smiles encouraging.

They start with simple tests.

Cas puts duck tape on the ground in a line and makes Sam walk forward and backward in a straight line, look up and touch his nose, bend down, twist, jump on place, jump far from place, duck, do push-ups, crunches, lift weights – almost all kind of physical loading. Cas explains him it is a routine check and that after almost 8 days in a saliva tank he needs to stretch. He does sight and hearing check as well. While observing Sam's movements Cas doesn't stop admiring his amazing body. And he doesn't even feel embarrassed.

He makes Sam to tell the English alphabet, the German alphabet, Korean alphabet, Swedish alphabet and he does perfect. The language protocol is perfect. He recite some of the laws in the Laws and rules protocol and most of them Sam says he doesn't like, which Cas finds very amusing.

'So' Cas leaves his notes on the desk 'Physically, you are perfect.' And he rests hands on his knees.

'Cool' Sam smiles. 'Was that all?'

Cas exhales, and licks his lips looking up at him 'Not exactly. I have to get to your system, your codes, your personal protocol. And I have to load you in the main computer with identity.'

'How you are going to do it?' Sam frowns.

Castiel looks at him a thinks for a moment or two. 'You trust me right?'

'Yes' Sam nods determined. 'You understand me. You saved me. I have no other choice but trust you'

After 5 minutes, Sam is sitting on a chair in front of a white screen, few bright lights shining from all around him. Castiel sticks those fuck tape circles with wires all over his neck and face, and puts some little such on his head, in his hair. Then on the both sides of him close to his head he places those things that look like cameras.

'Okay' Cas starts explaining. 'With those I'm going to follow your brain activity. And with those I'm going to follow your vital signs' After that he connects Sam with monitors to follow his vital signs like breathing, heartbeat, blood pressure and others. 'Now comes the unpleasant part.'

'What is it?' Sam tries to look at him.

Cas walks in front him holding something long and thin in his hands, wrapped in white paper or something, and that's connected with wire coming from behind the chair. Cas removes the paper and Sam sees long, silver, thin needle and he swallows hard, breathing and heartbeat starting to rise which Cas sees on the monitors.

'Tell me, what do you feel right now?'

'I-I'm scared…' he admits and Cas' lips twists a slight smile. He's never seen that emotion on a sample. And the trembling of the voice sounded so sad. It is exactly the way he had read about it.

'I understand. I have to insert that needle up to your brain'

'What…? No…' Sam shifts uncomfortable on the chair.

'It's alright' Castiel places hand over his. 'I will do it very gentle and once it reaches your spot you won't feel it. It's very thin. It will hurt just a little.'

'You didn't say it will include such stuff' Sam is almost on the edge to cry which Cas finds adorable but he feels his stomach clenching, knowing that Sam is scared and upset.

'It will be fast, I promise. I'm here right? You are worrying for nothing' Cas winks at him and caresses his knuckles. Sam looks down at their hands and thinks for a moment. 'Longer you think, scarier it looks'.

The next minute Cas is standing behind him and moving the hair from his neck, cleaning his skin with disinfectant.

'Just don't move and breathe, relax.' Cas whispers and presses fingers to the back of his neck where the spine goes, to find the right spot.

He finds it and takes the needle, pressing carefully only the tip. He pushes and slides 2 inches, after that little more and keeps equal slow pace of penetration.

'AAaaah… uuughh.' Sam cries and squeezes his eyes.

'Shhh… little more' Cas is concentrated and keeps pushing deeper.

'UUUUHHGG, STOP' Sam cries and tears starts streaming out of his eyes. His legs are shaking and he wants to move but Cas is squeezing his shoulder where it meets his neck and keeps pushing the needle. 'NAAaWW, PLeaSE STOP!'

'Almost there, almost done' Cas tries to calm him, but it's not really working. It's a whole miracle Sam hasn't already run away.

'IT HURTS, PLEASE, AAAAAAAAAH' Sam cries louder, face cramping in pain as the needle goes so fucking deep in his head, in his skull and leaves that burning feel all over his head, down his spine. Cas pushes just little more and stops.

Sam's crying suddenly stops and he doesn't feel anything. The nerves all over his body are calm and he feels tired.

'Cas, I don't feel' he sobs almost in panic. Cas comes around and squeezes his fingers, the other hand cupping his cheek and lifting up his chin just a little bit to look at his red wet eyes.

'You feel the needle inside you but it doesn't hurt. That is what had to happen. You did it. It's okay now' he brushes with fingers the wetness from his cheeks.

'You said it's going to hurt just a little bit' he frowns.

'I'm sorry. You have no idea how my stomach was clenching while listening you cry. But it's over. It's done. Won't hurt you again like that.' He snorts, smiles and brushes few more tears, and even licking his fingers 'Tears… amazing. Never seen such.'

Castiel turns on all the equipment, takes few minutes to set everything and starts copying Sam's protocols on his computer. Meanwhile he plays some short movies on the white screen, leaving Sam to watch them in peace. While the codes and the protocols are getting copied and read by the computer in the current moment, Cas observes the brain activity monitors, taking notes. He enjoys how Sam starts laughing on the funny movies, how he reasons on the philosophic movies that tell stories without any talking – only pictures and movements. And Castiel is just amazed, fascinated. He thought that those things were unnatural, wrong, not possible. All those who ever showed a slight sign of thinking and reasoning was sent to be re-constructed. The beings from the factory weren't capable of reasoning, discussing, dreaming and creating. And it is Sam. Doing it so well.

Castiel is learning from Sam in that moment. He plays him some sad movies and at the end one short sad movie on which he starts whispering the story about it.

'This is a family of elephants that have to travel away to find a better place for living. But the babies of the mother elephant are sick… and they have to leave them behind.' Sometimes he pauses and keeps talking as the movie goes 'And here… you can see one year later the family comes back and the mother elephant cries over the bones of her own babies that she recognizes.'

He observes and notices how fast and strong the brain activity is. And he hears Sam sobbing. And while the man cries he collects few of his tears to check them as well.

'Cas, it hurts…' Sam looks up at him, the sobs make his whole body shake a little, and he squeezes eyes to let the tears roll down and clear his sight. Cas knows it hurts Sam's heart, Sam's feelings, not physically.

'You are human… you think, you feel… you have your flaws…'

'No, please don't…'Sam begs and pushes away from Cas staring at him with fear.

'Hey, hey it's alright' Castiel squeezes his fingers again. The monitors show faster heartbeat. 'It's fine. I'm not going to hurt you. Come on, tell me, what upset you of my words?'

'When…. When I heard those words for a first time… after that they stuck tube in my throat and locked me in a tank, in which I thought they were trying to drown me… I was terrified.'

'That time is gone. I'm not going to lock you in such place. I want you to feel good. To feel on place. What do you think? Me and you? Together. Against the world.'

Sam looks at him with curiosity and smirks 'Are we not enough to fight the perfect world? We won't get too far.'

'Once I read your code and protocol we will see how to flip the switch of the others and change everything. We won't be alone…'

Cas leans and presses lips to Sam's forehead, closing eyes and staying like that for few seconds that feel so damn good. Like nothing both of them ever felt. He pulls back and tries to step back when Sam catches his shirt and pulls him back, looking closely in his eyes and breathing warmth on his lips. Blue meeting hazel. Chaos meeting perfection. They slowly close their eyes and cut the distance between their lips.

It's soft, and warm and so natural, comforting. As if the world stops for a while.

The vital signs monitor starts beeping and Cas breaks the kiss to look up at it. The pulse had risen high and the monitor marks it as something wrong. In other circumstances it would mean water-tank of imperfection. But not this time.

'How do you feel?' Cas squints.

'Pleased and happy' Sam smiles and pulls him again, hungry for more of those kisses. Cas relaxes and enjoys one slow kiss again… feeling Sam's wet tongue parting his lips, trying to crack a path deeper in his mouth. And Cas starts loosing himself. His hands slide down Sam's smooth naked chest and the man lets a short moan, making Cas snap his eyes open and pull back. Sam frowns due the lack of physical wet contact.

'What was that?' he asks, a smile trying hard to form on his lips.

'Something nice. It was feeling good… almost painfully good. I thought it's the best reaction to express my bliss.'

'I felt a shiver through my spine by that sound' Cas admits.

Cas goes back to the screens and the computer to analyze the brain activity of all the emotions that Sam's showed and experienced. He reads the codes from every emotion Sam had and goes in the copied file to check the protocols.

'Wanna tell me, what was the first thing that occurred in your mind when you opened your eyes for a first time in that lab?'

'I felt amazing, a bit scared. That white room, and all those robots touching me was scaring me a little. I had knowledge about things, I saw my body. So beautiful, comfortable, and I was enjoying touching it. And I thought: what could I do with my knowledge and my body. I wanted to create; I wanted to dream to live. I started asking question, I was confused. And then I heard those words and the next moment those people in white shirts tied me up and exported me to the hall with the tanks. They opened my mouth and violently, painfully stuck a tube down my throat. I was terrified. They pushed me inside the tank and put ropes around me, locked the door and pressed some buttons. I was crying, I was trying so hard to escape. The tank started filling up with yellow saliva till it was full. I was thinking I was going to die… I didn't want to die. Something pinned in my skin and I was fighting and fighting… till I couldn't move my limbs anymore… My eyes slowly shut closed… and the next thing I remember is lying on the tiles, chocking on the tube and… your pretty face smiling above me.'

Cas is listening carefully to him. There was never such extreme case before. As he listens he observes the screens. He had never seen so powerful brain activity before. And the codes for the feelings – definitely haven't seen such difficult codes before.

'You are amazing Sam' Cas whispers.

Sam snorts 'I'm just a flaw…'

'What the…' Cas exclaims quietly and squints at the screens.

'What is it? Cas…?' Sam tries to turn to him but he is unable and a shiver runs down his spine. 'Cas, talk to me.' He pleads.

'Those are not the protocols that are load in our factory. I've never seen such codes before. What kind of protocol is that?'

'What do you mean?' Sam frowns. Cas moves the stuff on the thin tablet and steps in front of Sam so he can explain while watching the screen.

'Every individual gets installed with the same basic codes and protocols. Those protocols and codes come from the headquarter and we only have to place them. Well before that they go through a second check from our specialist before being installed on the individuals. And…' He silences and slides fingers over the touch screen, squinting and thinking.

'Cas, what is it… Tell me, please!' Sam looks at him expectantly.

Cas looks at him with confused look, as if he sees Sam for a first time and says quietly 'Your codes and software have not been checked… they have been installed directly from the headquarters. Sam… ' he silences 'you are not an incident… you have been planned to be broken. I mean to be unique. You are installed with protocols that the real humans have. Sam… there is someone at the headquarters, that wants you to have those protocols. Someone that wants to turn artificial humans into real ones.'

'What for? I don't understand'

'I don't know Sam' Cas looks at his tablet again. 'But I intend to find out. And even help'
