This takes place after the 57th Expedition outside of the walls. Enjoy

'Shut up...' Levi thought as the man talked to him. This man, was Petra's father. "Petra..." He muttered under his breath, letting her name roll off his tounge. Mr. Ral chuckled lightly, oblivious to the fact that his daughter had died to the hands of that monster. 'The female titan.' Levi growled inwardly. "She has written many letters to me." He smiled. "She claimed she wanted marriage, but I'll let you children handle that." Mr. Ral chuckled as he gentle patted Levi's back. His head hung lower, his face showing one, simple emotion. Grief. He was grieving for her. He missed her dearly. Levi chuckled softly, something he rarely did. "You never know you love something until it's gone forever." He said, stopping the man in his tracks. He understood quickly what had happened, his baby girl was gone. Levi left the man to cry for his daughter, allowing him to scream his insults towards the young captain. He sighed lightly as the civilians muttered, complained, and insulted the Survey Corps. "The brats have no idea what we have been through; what we have seen." He closed his eyes, taking a deep breath. The memories flooded in like a storm. He remembered her bringing him his morning coffee everyday. Remembered how she was the such a kind and gentle woman off the battlefield, but became extremely alert when a situation was dangerous. He remembered her being promoted to his squad. Levi remembered every detail about Petra. For the first time in forever, he almost allowed his emotions to take control of his body. 'But...not now. I can not let my guard down just yet, not one of these civilians shall see me become emotional. I am Humanity's Strongest Soldier.' He thought.

Once he was in his office, Levi looked at the paperwork with a deadpanned stare. "This bratty paperwork never seems to disappear." He grumbled as he grabbed a quil and began to work on the papers. He sighed lightly as he looked up at the door, a memory of Petra bringing him massive stacks of paperwork. Though the papers annoyed him to a great extent, he did enjoy having her company. The corporal growled lowly as his grieving had gotten worse. He had gripped the quil tighter, breaking it. His hands began to ball up into fists in his hair. He let out a yell of distress and anger, then began to cry. He had missed her and he was sorry. He felt as if he had failed. His breathing became staggered as he was having a fit. Suddenly, there was a knock at the door. He didn't have time to compose himself, he didn't care too. "State your name and business." His dry, shaky voice said. "Cadet Armin Arlert, you've been summoned by Commander Smith." Levi slowly began to compose himself. "We have information of the Female Titan." The young cadet stated. The corporal's face turned to a scowl. He got up from the chair and opened the door, following Armin. The boy lead him to a room with squad leader Hanji, Commander Erwin, and his fellow cadets. Armin took his seat at the foot of the table, sighing lightly. 'Poor Levi...he is suffering from loss. However, the Female Titan shall pay for this.' He thought as he laid out his blueprints filled with plans. "Upon close inspection, I have figured that the Female Titan is Annie Leonhart." No one was shocked, except Eren. "A-Annie, how?" Mikasa looked at him. "She has the features of the monster." Erwin agreed with her. "It's also very intelligent, such as your Titan form." "But-" Eren started, but was cut off by Levi. "Shut up, brat. You have seen the Titan's fighting style and Annie's fighting style. They are very similar to each other. Do not deny it, your friend is the Female Titan." Eren quieted, allowing Armin to continue on with the plan. The plan was very clear, they were to catch Annie off guard and the others were to attack her and arrest her before she turned to her Titan form. Levi smirked as one thought ran through his broken mind. 'May you rot forever in your soon-to-be cell, Leonhart...' The group was dismissed from the meeting room after the plan was explained with more elaborate detail. Even with his grief, Levi felt as if he could calm down for once today. The thought of having the young girl put in her place made him feel a sadistic happiness. However, Titans did unexpected things. Even the intelligent ones. There's no telling how the mission would go the next day and how many lives are to be lost, if things were to go wrong. He sighed lightly and sat at his desk, deciding to drown himself in the sea of paperwork. 'I need to get my mind off of this.' He thought as he began to continue the work.

That's all I have for now. It's a school night and I need to sleep. Anyways I hope you enjoyed it, bye.
