Four hears gunshots but is not worried, Jeanine has him and the simulation well-guarded. He is surprised the rebels made it this far but his only concern is to make sure the simulation runs smoothly. As he is watching the code and cameras around the city, he hears the door open behind him. He turns to look who entered and his eyes narrow, the traitor survived. She has a gun and he needs to protect the simulation.

The word protect confuses him, there was something else he was supposed to protect, something that was very important to him but he can't grasp the thought in his brain. He raises his gun at the traitor, taking more effort than it should, as if his body is fighting something for control, and says, "Drop your weapon."

The traitor speaks to him and again his mind becomes cloudy as he hears her say, "Tobias, you are in a simulation." He is confused, he is not in the simulation, he is controlling the simulation. He shakes his head to try to clear these thoughts from it, she is just trying to confuse him. "Drop your weapon or I'll fire." His hand tightened on the gun, pointing it with more force at the traitor, and his stomach flipped with his action. Why was his body so against shooting this girl? She stares at him and he doesn't notice her drop her gun.

"Drop your weapon!" He shouts, his body on overload from the conflicting emotions. He should just pull the trigger and get it over with but his finger is fighting him. He hears her respond and the voice sounds so familiar, makes him want to smile but he stops himself. She is a traitor, she is not his friend. All of a sudden, she lunges at him and he fires out of reflex, the bullet missing her. He sighs in relief but doesn't understand why his is feeling relief at the traitor surviving. She grabs his wrist and knocks the gun out of his hand but he is stronger than her, she cannot beat him in this fight. He sees her dive for the gun and he grabs her and shoves her aside, gentler than he should have.

She makes eye contact with him and he sees more pain than he should in her eyes and it throws him off. He doesn't know how this traitor is getting into his head but his temper takes over and he punches her in the jaw. He sees her attempt to kick him way before she throws her foot in the air, as if he knows how she fights. He catches her foot and pulls her down and he hears her scream at the impact on her shoulder. His hands begin to reach out to comfort her but he clears his head and throws out his foot to kick her instead, not trusting his hands.

She grabs at the gun but Four grasps her by the hair before she can get to it. He smashes her face into the wall as she tries to grip his wrist again. He hears her choke out, "Tobias," and again he pauses. His grip loosens as the idea of hurting her makes him sick and she takes the opportunity. She kicks him, slips out of his grip and grabs the gun. He curses at her ability to confuse him and turns to find a gun pointed at his chest.

"Tobias, I know you are in there." Who is this girl? Why does she talk to him like she knows him? He would never associate with a traitor. He moves toward her, anger billowing out of him at the power she has over him. She struggles to her feet and he has to control his hands from reaching out to help her, no idea where that reflex comes from. She begins to beg and his mind becomes cloudier with confusion.

"Tobias, please. See me. Please see me Tobias!" She shouts at him. He scowls, his brain trying to figure out why this girl knows him and why his body reacts so strongly to her. He sees the gun shake in her hands as if she can't kill him either, his body is going to tear itself apart fighting to hurt and help her. Four has no idea what is happening as she presses the gun into his hands. Why would a traitor give him the gun when he is just going to kill her with it? He grabs the gun and pushes it into her forehead and as he does it, he feels her hand rest on his heart. Something flashes in his mind, two people sitting below a waterfall, a hand resting on a chest just like this one is. For some reason he thinks it is the girl and him sitting there, but that can't be right, he's never seen this girl before in his life...has he? He grits his teeth to stop the confusion, angry again at the thought of her somehow controlling his mind. He clicks a bullet into the chamber, ready to remove this threat from his life so he can continue his job.

He hears her whisper, "Tobias, It's me." His heart is pounding, why can't he pull the trigger? Why are his palms suddenly sweaty with the thought of this gun pointed at her head, it's what traitors deserve, he knows that. She furthers the confusion by stepping forward and wrapping her arms around him as he stiffens. This feels so comfortable and right, his eyes begin to close as his body surges with…happiness?

Those arms around him pulled his mind out of the fog and he suddenly realizes he has a gun pressed against Tris' head and he was about to kill her. The events of the past hour came back to him, the injection, watching Tris be led out to be killed, hitting her, pressing a gun to her head. Everything washed over Four and he was filled with anger. Boiling rage at the thought of Jeanine controlling people and thinking it's ok makes him want to find her and torture her, but all he can think about is the girl in his arms, willing to sacrifice her life to not end his.

"Tris." His mouth collides with hers and wraps his arms around her. He can't get himself close enough to her and he begins to shake, the after effects of the serum wearing off. He tries to not squeeze her too hard but he can't control his body's need to hold her and never let her go. Eventually his body relaxes and he sets Tris down and stares into her eyes. He sees the strength and fire that pulled him out of the simulation burn in her eyes and he has never loved her so much. He brushes her hands over her face, lips, cheeks, and he feels himself start to break at what he did to her. He sees the redness on her jaw and a moan escapes his lips. He can feel the tears start to form as he remembers his father hitting his mother the same way. He sees her eyes fill with concern and she grabs him and wraps him up as tight as she can, he returns the hug and feels her lean into him.

"How did you do it?" Four hears her ask, but he can't answer, he's still astonished she was willing to risk her life to save him. He looks at her and says exactly what pulled him out of it, wanting her to know how much she means to him.

"I heard your voice."
