"Big bro, is everything ok?" Isabel replied, worry written all over her face.

That was all she asked while staring up at Levi's unusual expression, eyes wide as he stared at the two of them. Isabel and Farlan weren't supposed to exist, weren't supposed to even be alive and, as he looked around the room once more, then back at them, he felt a wave a nausea overcome him as he gripped on to his stomach and fell to his knees. Worried for his condition, Isabel knelt beside him, hands on his back, as she watched Levi fall apart; strangely, Levi couldn't wrap his head around what had just happened.

"Hey Levi," replied Farlan while standing in the doorway, eyes just as worried as Isabel's as he looked around the room. "Are you sick or something?"

Looking up at him, body convulsing and sweat rolling down his face, Levi nodded his head as he softly pushed Isabel away from him and crawled over to his bed. He was definitely sick; however, it wasn't an illness that caused him to feel this way. As it stood now, he had no idea where Yuki was and, to make matters worse, he'd essentially been sent back in time, a time where the three of them still lived in the underground and knew nothing of the survey corps or Erwin Smith; as he looked over at them and their worried expressions, he wanted to be happy and relieved that they were with him again but, with all that he had learned and experienced, he could only feel sadness as his hands gripped on to the bed sheets.

"Isabel," Levi asked as his arms wrapped around his waist. Shakily, she walked over to him and sat down on the bed.

"What is it Big Bro?" Her reply was so sweet to his ears, so nostalgic as he shakily looked up at her.

"Can you get me a glass of water?" He almost couldn't get the words out as a cough escaped his lips and another wave of pain shot through his chest. With soft eyes, she nodded her head and motioned for Farlan to move out of the way.

"Coming right up Big bro." Sitting up from the bed, she made her way out of the room and left Levi and Farlan alone. For a moment, the two of them sat in silence and, as Farlan stared at Levi, his back leaning against the wall and eyes lit with worry and confusion, he could only think that something did sit well with him and what he'd just been exposed to. Yes, they lived in the underground, so Levi falling ill wasn't hard to believe; however, as he looked at the fear on Levi's eyes, he knew something wasn't right. All the times Levi had ever been sick in their presence, he'd never expressed himself like this. Looking down at Levi, a sigh escaped his lips as he crossed his arms.

"You look like you've seen a ghost Levi." Startled, Levi looked up at him, then turned his eyes to the ground.

"I'm just sick Farlan." Placing his hands against his forehead, he tried to push the pain down but could only think about what had just happened and the loss he'd just experienced. Was she lost to him forever now? Everything he'd had in that other world had been so perfect, a paradise in his mind, and now it was gone and, what made everything even more horrifying, was that Yuki had gotten caught up in it.

"Cut the shit Levi." Farlan cut straight to the chase, knowing full well that something as simple as being sick wasn't why Levi was shaking on the floor. Walking over to him, he kneeled down, grabbed Levi by the back of the head, and forced him to look up at him. He knew it was a risky move, seeing as how Levi could lash out seriously hurt him for such an action but, in his current state, he thought he'd take his chances and go for it. "Why do you look like you've just seen a ghost?"

Crying out, Levi pushed Farlan away from him and gasped as he watched him fall on his back. They were supposed to be dead, both of them, and now he felt as though he'd lost his mind. All of his surroundings seemed so familiar, just like they'd used to when the three of them lived in the underground. His room looked exactly the same, the same rusty old bed that would always hurt his back after sleeping in it, the same night stand beside it, and the same darkness that always filled the room because of its inability to reach the sun. He wanted it all to be a dream, wanted to be back in Yuki's arms and feel her touch again but, as he gripped his hands in to his sides, his nails digging in to his skin, he felt the pain that followed soon after and knew it wasn't a dream. It was real, and it was definitely a nightmare in his mind. Not only had he been sent back to them but, as it stood now, the memories he had of the future were perfectly intact.

"What the fuck Levi!" Farlan screamed as he sat himself up. "What's gotten into you?"

Hearing Farlan's scream, Isabel ran back in to the room, eyes wide as she stared down at the two of them. Clutching Levi's water in her hand, she walked over to him and slowly handed him the cup, her eyes still worrisome for his demeanor. Instantly, Levi gulped down the water as an exasperated sigh escaped his lips. Nearly choking on the water, he released a cough as he wiped away the water that had trickled down his face.

"Levi," Isabel began while walking over to Farlan. "What's going on?"

Levi looked up at the two of them, fear on his eyes as he sat the cup on the ground. If he told them the truth, the possibility of them not believing him was extremely high and, now that they were back in the underground, he had no chance of making it back to the surface without Erwin's interference; now that he thought on that little bit of information, he wondered how long it would take to find him. He knew the three of them had made quite a name for themselves down in the underground, seeing as they used the 3dm gear to get around the city; but, as it stood, he didn't even know if the gear was in their possession. Sighing, he tried to reign in his emotions as he shakily helped himself sit on the bed. Isabel ran to his side, trying her best to help him with what she'd still believed to be a sickness but, turning her direction, he shook his head, wrapped an arm around her shoulder, and pulled her close to his chest.

"What's gotten in to you Levi!" Isabel exclaimed as she felt her head against Levi's chest. Levi was never this affectionate, not even to them, and they were his closest friend.

"Isabel, Farlan," Levi began as he motioned for Farlan to join them on the bed. Slowly, Farlan stood up and began to walk to the bed, softly mumbling under his breath about "punching him in the face" if he tried anything like that again. Chuckling, Levi pulled Farlan in to him with his other arm and softly began to cry.

"Levi…" Isabel looked up at him, eyes wide as she witnessed him crying before her.

"The two of you are supposed to be dead." The words were spoken in a whisper but, judging by the shocked looks on both their faces, they'd heard enough of what he'd spoken and, after taking in what he'd said, they grew even more distressed as they tried to press Levi for answers.

"What the hell do you mean Levi?" Isabel asked.

"Yeah," Farlan replied as he pushed Levi away from him. He crossed his legs on the bed and sighed. "Whatever the fuck this is, well, it isn't fucking funny."

To avoid any more distress on their part, Levi released Isabel from his hold and slowly began to explain everything to them. At first, they laughed it off as some nightmare that Levi had had in the middle of the night; still, Levi persisted as he told him his story of how they'd met Erwin and how they had gained the right to leave the underground. Luckily for him, they weren't trying to play everything off as a sick joke and, seeing as Levi rarely joked, they knew he was serious about what he'd been saying. Levi wanted to avoid discussing their deaths, seeing as how he always blamed himself for the reasons why they'd died in the first place; however, he needed them to believe him and his words. He needed them to believe everything he told them. Perhaps with this advantage over the enemy they might stand a chance at winning this time. Still, he felt a hole in his chest as he thought about Yuki. That world he'd been exposed to was now lost to him and, though he wanted to go back, he had a duty to his friends and his fallen comrades to flip the script and rewrite history.

"So, you're saying that the Titan's are people?" Farlan asked, clearly at a loss for words as he wrapped his head around what Levi had told him. Levi nodded his head and sighed.

"Based on what I've learned so far, the Reiss family has the ability to alter the memories of everyone within the walls. We were close to discovering the truth, but we failed our mission." He thought back on his final mission to recover the truth from Eren's basement, threaded his fingers together, and yet again released a hearty sigh.

"The truth about what?" Isabel asked, clearly intrigued by where Levi was going with everything. Levi gave her a soft smile, happy that she was paying attention to him.

"Our final mission was to recover documents from Grisha Yeager's basement. Wal Maria had fallen to the titans years before so me, along with many others, fought to fight for the truth against them." He saw the wonder in their eyes as they listened to him and hoped, more than anything, that they believed him.

"So you're telling me that normal people can be titans?" Farlan asked, clearly amazed at the very idea of Titan shifter's, even the idea of it, being a possibility.

"Yes," Levi replied, dread in his eyes as he remembered Eren and the other's.

"How do you know so much about these things Levi?" Isabel asked, still a little doubtful. How could Levi explain it to her in a way that made sense? Everything he was telling them was the truth but, even now where they were, he had no way of proving it to them without finding Erwin and rejoining the survey corps.

"I don't know how to explain it to you Isabel." Rolling her eyes, Isabel helped herself off the bed and began to pace around the room.

"You're telling us that everyone around here, even outside the walls, has had their memories altered by the government, that Titan's aren't really monsters but people, and that we're going to join the survey corps and, I assume in the near future, get killed by them." She'd done a good job at summarizing everything he'd said. In a nutshell, that summed everything up, at least for the time being.

"How can we believe what you're saying?" Farlan asked, still a bit shaken by everything.

"You have no way of knowing," Levi replied, eyes focused on both of them as he slowly helped himself off the bed. Luckily, the fear and the pain had finally died down a bit as he walked over to Isabel and pulled her in for a hug. "However," he continued, chuckling at the surprised look on her face. "Would I lie to you? If what I'm saying isn't the truth, then why would I waste my time with telling you?" facing Isabel and her shocked face, he smiled as he softly rubbed her back.

Still taken aback by Levi's change in demeanor, seeing as he'd never been this affectionate with her, she buried her head in to his chest and nodded her head. She knew Levi wasn't one to mince words so, knowing him well enough, she knew that when he told them something, nothing but the truth escaped his lips, at least the truth from his perspective.

"If what you're saying is true big bro," she began, eyes looking up to his. "Then what are we going to do about it?"

Levi knew what to do, at least knew the first step to take in his second chance to save humanity. Still, he thought about Yuki and where she might be now. He'd watched her get sucked in to the portal as well so he had no way of knowing when or where she might be. Though he'd told Isabel and Farlan everything he knew about the Titan's, he'd left out how he knew so much about them or how he'd made in in to Yuki's world. That bit of information would have been too much for them to handle; certainly, in the near future, he'd explain it to them but, for now at least, they needed to focus on the their next mission and find the one man who could make his goal a possibility. Hopefully, this time around, they might be able to save more lives.

"We need to find Erwin Smith."
