I am so so sorry I didn't update but I had school and I had writers block for like 3 days. It was hell okay but here it is! The End. It's a bit soppy and unbelievable but eh, it shows how much Tris actually loves Tobias I guess.

He was back in his fear landscape.
No no no no no. He knew they were watching it, like they used to in Dauntless.
No oh god no. He couldn't go through his fear landscape when he knew they were watching. He just couldn't. But he had to. God knows what they'd do to him if he didnt, the monsters.
Tobias went through his fears, as if in a dream, going through the first three as slow as he could. Purposely trying to agitate the people who he knew were watching.
He got to his last fear, finally. He took a deep breath, shut his eyes and waited for the screaming to begin.

It never came.
Wait what?
Tobias opened his eyes, warily and stared at the completely empty plain white room he was in. There was no sign of anyone, let alone Tris.
What was this?
He sank to his knees slowly and pressed his lips together, trying not to scream. What was this? Where was she?
He put his head in his hands.
He was alone.

Tobias Eaton was alone. She was gone. Forever. And he was still here, stuck on this shithole of a planet, all alone.
He sat curled up, with his head in his hands and his hands trembled with the effort of holding in his emotions. He couldn't forget that there were people watching this.
Suddenly, a voice echoed through the room. A ghost voice. The voice of a girl he once knew. A-no-The girl he loved. Only at the same time it was not her voice. It sounded so much like her. But at the same time there was something different.
"Tobias, you have to let me go"
And then she appeared, suddenly standing right in front of him, dressed in her Dauntless clothes. He looked up at her. and then bent his head back down. It hurt to look at her now. She had her hair tied back in a pony, and she had a small, sad smile on her face.
"I watched you, you know. I saw you day after day, put yourself through this torture, only to have a glimpse of my face. A feel of my skin. I watched you and it broke my heart" He realized what was different with her voice now. It echoed with every syllable she spoke, and it had a certain quality to it. Like she was speaking from very far.
"I know what I did hurt you, and I know that it hurt others, but probably you the most. I don't regret doing it, I wouldn't have been able to live with myself if I had sent my brother off to his death"
Was she real? Was this part of the fear? Or was she-as stupid as it sounded-a ghost?
"I know what my death is doing to the others as well. Christina might not show it, but she's almost as torn up as you are. She hides it very well, which is surprising as it goes against everything in her Candor nature but she does. For your sake, I suppose. She's not doing well. You have to be there for her. All her friends are gone, and she sees no reason to live-"
"What about me?" He asked, barely whispering, hoping she wouldn't hear him while at the same time hoping that she would.
She did.
Tris bent down and took Tobias' chin in her hand and lifted it up gently. So she was solid, which rules out the ghost theory. Not that he was seriously considering it.
"You have so much to live for. You have Zeke and Amar and Christina and even Cara and they all care for you" He felt like shouting "But all I want is you" but he stayed silent.
"You help her and she, you. It's the way of the world. Everything has an end, and my end came a bit too soon, but you can't let that happen to Christina. Or you. You are stronger than this. You can help Christina get through this and she can help you. Please"

Tobias felt a tear slide down his cheek, but he didn't bother to wipe it away, all thoughts of the people watching gone. She felt so real and solid and there. She was right there. And she was telling him to move on. He didn't care if this was some trick designed by the Bureau to get him to stop taking the serum. He didn't care whether she was something his fear landscape had conjured. He only cared about the fact that she was here, and she felt more real than any of the other times. And he listened to her.
Something told him that he should.
"But what if I'm not? What if I'm not stronger? What if this kills me?"
"Then you would have disappointed me. The Tobias I knew was not this. The Tobias I knew was brave and strong, fearless. Dauntless. Be that person again. Be the person I love. Be yourself again"
He shut his eyes buried his head in her neck and he cried. And he cried and he cried some more. He stayed like that for a long time, with her embracing him, rather than him embracing her. He needed this. He needed her. But he also knew that he needed to let her go. Holding on to her was physically and mentally killing him.
She held him and he, finally exhausting his seemingly endless supply of tears, fell asleep in her arms.

"Tobias?" He groaned and tried to roll around. And came to the realization that his arms were strapped to the gurney.
What the hell?
He opened his eyes, slowly and bright light pierced his eyes and sent a shot of pain through them. He shut them again.
Slowly, eyelids flickering, he opened his eyes.
Matthew and the old man were staring down at him. Why did they look so pale? Or maybe it was just the light.
"What do you want? You got what you wanted didn't you? You saw and heard everything, didn't you? Now you know why I take the fear serum"
"Yeah well... yeah"
"Happy now?"
"Not really. I had no idea how bad it was for you. I'm sorry about making you relive that, but you really have to stop taking the se-"
"Okay, okay I got it. I'll stop"
"Really?" Matthew's eyes widened slightly, surprised that Tobias had given in that easily.
Tobias really didn't want to see her again. He loved her, but that was exactly why he didn't want to see her. He loved her so much it almost killed him. But now it had to stop.
"I promise okay? Now can you unstrap me from this fucking gurney"
The guards untied his arms and escorted him back to his room, where he took the remaining vials of fear serum he had, and flushed them down the toilet. A waste, definitely but he did it. His Abnegation side got a bit agitated as he watched the liquid disappear in a whirlpool, gone
forever. This was it.

The next day, he went and talked to Christina. They talked about Tris and the memories they both had with her, and although they both ended up crying, hugging each other as if their lives depended on it (which it did), they both felt slightly better. Not very much, but it was a start. Tobias knew it was going to be a very long time till he was okay, but if he never started, he would never be okay.
Tobias talked to people more, and Matthew watched him slowly get better, amazed at how much better he had gotten since the last time he had gone through his fear landscape.

The very same fear landscape that had in fact, changed Matthew's whole perspective of life, death and love. He smiled slightly and felt a chill going up his spine, knowing that what little he had seen through the computer monitors and heard through something Andrew (the old man) called a cell phone, he would never tell Tobias, because as soon as Tobias had collapsed on the ground, the lights had flickered, once, twice and then gone out altogether. Not only in the lab, as they later found out, but the whole place, which was more unsettling. There had never been a black out before. Never.
As soon as the power went out, there was a beat of silence and then, Andrew immediately activated the mic (by pressing a button on his watch. How the hell..?) that they had embedded into Tobias' skin along with the fear serum they had injected and took something out of his pocket which he told them was a cell phone, and the mic sent everything it heard to the phone. So, gathered around a small illuminated rectangle, sat four men, in the dark and they listened. The mic would shut down as soon as Tobias came out of the simulation and he would never even know it was there. What they heard shook them all to the core.
They heard Tris speaking, and then Tobias' muffled sobs which were slowly replaced by silence.
And then;
"Tris, come on, we have to leave. He's asleep and he'll wake up out of the simulation. It's better to leave now, it'll be easier on you too" Another voice come back from the dead. Natalie Prior's voice. It had a kind of echo, a haunting feeling to it, like Tris' had and it chilled them all to the bone.
"I will mom, just a little more time" Tris' voice replied.

Then Tris began humming something, so quietly, they had to strain their ears to hear. After the humming ended, there was a short silence and all they heard was Tobias' shallow breathing.
Soon after, the lights came back on and illuminated the four people standing around the gurney, one of them clutching a phone, one of them staring at it in shock and all of them pale and trembling.
Tobias came to slowly afterwards.

Ghosts? No. Andrew had a better-saner-theory to present to the Bureau that had assigned them on figuring out why Tobias needed the serum. Tobias' subconscious had conjured up the small conversation between Tris and Natalie after he had gone to sleep and the lights had coincidentally gone out at the same time. And come on at the same time when Tris had left. Totally.
Matthew watched from afar as Tobias laugh, for the first time in nearly nine months and smiled slightly, knowing that Tobias was better off not knowing what had occured after he had fallen asleep.
