Here Levi stood in the office, Erwin standing by the window. "I have always trusted your decisions Erwin." he began, looking at the tall man. "But is this really the best one?" Erwin's eyes looked down at the empty courtyard outside the window. "The other ones have been dealt with Levi, he's the last one. We kill him and we will finally have won." Levi shuffled, looking around the room now, trying to take in every detail. "He's a child Erwin, he's lost his sister and his best friend during this whole ordeal. Now you just want to kill him? After what he's done to help us?" Erwin turned to him, looking him straight in the eye. "You think I don't know that? The others were children too before the fall. They were turned into soldiers Levi, they knew what the cost of it was. The other three, the ones who killed innocent people deserved to die."
Levi snapped back into reality, he felt the cool air and the smell of salt hit his face. He then looked at the boy beside him, the boy who had helped them defeat the titans. "Look Levi! The ocean." his smile was back, it was a true smile this time, one of happiness. If only he knew how quickly this happiness would fade. "Yeah, it's pretty big." Levi managed to get out, feeling sorry for the boy. He noticed his eyes how they were when he had talked about defeating the titans years ago. "I wish Armin and Mikasa were here to see this." his face fell and Levi sighed, putting a hand on his shoulder. "We all lost people we cared for, I'm sure Armin and Mikasa aren't in pain anymore." Levi looked back at the ocean, going back to his thoughts.
"Those three were children too Erwin, they must have been scared." but Erwin shook his head. "Those things were not children Levi, they were monsters and he'll end up the same way if we don't kill him." Levi slammed his fist on the desk, shaking in anger. "Eren Yeager! His name is Eren Yeager! Not him or he or monster! I know Eren, I was there when Armin and Mikasa died. His reactions to their deaths were human, I refuse to believe he'd ever turn on us." Erwin looked at him again and heaved a sighed. "If we weren't to kill him, if we let him live. What would happen if he found out what we had planned to do. He would turn on us Levi, he would snap our necks or slit our throats in an instant. This 'child' if you wish to call him that is no human Levi."
Levi felt his hands reach for the dagger at his side, he saw Eren looking at the ocean amazed and decided it was time. He quickly got out the dagger, taking a long look at it before sighing. "I'm sorry for this Eren." before he could turn to look he stabbed him, quickly in the chest, in and out he plunged the dagger as the light from Eren's eyes faded. "I'm sorry Eren, I really am." Levi was trying to hold back tears now, he let out a sob covering his face with blood stained hands. "I'm sorry."
"You want me to do it right Erwin? Because I'm the only friend he has left now so you want to torture me and let me see his body go limp?" Levi looked at the ground. "If I don't what will you do? Kill me and him? Send someone else to do your dirty work?" Erwin sighed and walked towards him "Yes I would, Levi this is necessary. He can't live a normal life now you must understand that. You think people will leave him alone, they are frightened Levi. They don't want a monster running around pretending to be normal." Levi bit his lip, looking at the dagger on the desk. "A dagger? You want me to kill him with that? What is this some stupid ass book?" Levi sighed and took the weapon into his hands. "I'll do it Erwin, just leave me alone after this is done."
Levi stepped into the office, his hands shaking but the blood had dried on by now. "I've done it Erwin, it's done." he told the man, who once again was looking out the window. "Well done Levi, I'm sorry about what I made you do. It had to be done." Levi put the dagger on the table, looking up at him. "It didn't need to be like this Erwin, he could have lived." Erwin gave a small chuckle. "He was a monster, he was putting fear in people so I had you kill him." Levi looked down at the dagger. "You're a monster too, Erwin. I hope someday, someone kills you." he walked out of the room, slamming the door behind him and heading down the hall, still picturing the light fading from his eyes.
