I honestly think that this sucks so far, but if you like it, that's awesome. Hopefully I will feel a little better writing about this as time goes on. This was the first zombie fanfic I wrote in a year and a half, so it's a little rusty at first.

Jean did not realize that he had fainted until he had started gaining consciousness a few moments later. He was lying on the basement floor. He rubbed his head a little since it hurt a bit.

I did not just see what I saw before, he thought to himself and panicked. That was just a figment of my imagination coming back to haunt me. I totally did not just see that mangled face just before.

"I see you have awoken."

Jean tensed and sat up quickly when hearing Dr. Hartzfeld's voice. He hesitantly glanced around the room, but his eyes were quickly focused on Marco's mangled face again. He bit back another scream and quickly shifted away.

"W-what is that?!"

"It's the soldier of the 104th Trainee Squad that I just mentioned earlier," she mumbled.

Jean forced himself to look at Marco again. The tall boy looked a little jittery as he gripped onto the metal bar.

"B-but that's not Marco!" he gasped. "T-that is a monster!"

"That hurt."

He froze when hearing that raspy voice again. He looked at Marco and saw that his one, emotionless eye was staring back at him.

"H-he doesn't even act like Marco!"

"But he is indeed your friend," she assured him. "He died in the Battle of Trost, but I managed to bring him back."

"You should have left him alone," he muttered.

"Jean," the living corpse mumbled and stared at him. "You're frightening me."

Jean stared at Marco as he contemplated what he should do next. He then thought fast and quickly slapped himself as if trying to wake up from a nightmare.

It didn't work.

"This is insane, I tell you!" he muttered.

Dr. Hartzfeld shook her head and looked at him. "You will learn to live with it. You are his friend, after all. By the way, you know that you cannot tell a single soul about this, right?"

"Oh yeah, because I was totally planning on telling somebody," he mumbled sarcastically. "Why did you do this?"

She crossed her arms and looked at him. "You are looking at the greatest phenomenon in human history. If I can get my hands on more fallen soldiers, we could have our own army that could defeat the Titans with their skills. There would be more soldiers than you could ever imagine after this is through!"

"That's crazy talk!" he retorted and glared. "I can't believe you did this, and to Marco of all people!"

"Don't shout, Jean," Marco grumbled monotonously, and he started rattling at the bar irritably.

Dr. Hartzfeld looked at Marco and smirked as she walked over to him. "Are you hungry, boy?"

"Boy?" What the fuck, does he look like a puppy to you?

Marco quickly nodded, his one eye dilating.

"Don't worry, I will take care of that growling stomach of yours."

The doctor reached her hand into the bars to pat Marco's head. She did so and quickly flinched back her hand when he opened his mangled jaw wide and attempted to bite at her appendage.

"Don't be too hasty," she smirked as he then went down the hall once more.

Meanwhile Jean was in shock still, especially because of what he just witnessed.

Did Marco just… try to bite her hand?

"Jean."

That raspy voice caught his attention once more. He glanced at Marco nervously. The boy tried beckoning him closer to the bars, but Jean stood firmly in his place.

"Mean," he mumbled as he let go of the bar.

"I'm mean?" he muttered. "She was the one that was treating you like a dog."

Marco smirked slightly as he heard him. "I don't mind."

Jean shook his head slightly. "Marco… You're supposed to be dead. You shouldn't be walking around like this, it's unhealthy."

"I thought you'd be thrilled," he muttered quietly. "After all, this means that we can be together again."

He tensed slightly as he looked at him. "Marco.. I don't think that's possible."

"I will make it possible!" Marco shouted, and his voice sounded raspier and darker than earlier, which scared Jean more.

This is too much!

Marco's face contorted from hunger pains, and Jean tensed when hearing him growl. He reached out his arm from the bars and curled his fingers as he tried grasping at him even though he was too far away.

Jean did not like this at all, and he knew he had to get out of here before something worse happens.

"Marco." Dr. Hartzfeld came back and Jean's eyes widened when seeing that she had brought the boy a large portion of raw meat. "I have your food."

Marco seemed to lose his former train of thought as he grinned and reached his arm out more. "Hungry!"

"Here you go, then," she assured him as she tossed the meat over to him.

The boy grabbed it hungrily before hiding in a dark corner in the cell, and Jean's face paled since he heard the growling and jittery noises his former lover was making as he was eating.

"Do you care to stay and see him some more?" Dr. Hartzfeld asked the confused soldier.

"N-not right now," he stammered. "I need to get some fresh air."

Once he was sure he was excused he quickly ran off, feeling like he was going to get sick. Dr. Hartzfeld just watched him leave, her eyes narrowed. She then looked back over at where Marco was devouring his meal.

"Don't worry, my mangled fiend," she mumbled as she listened to him eat. "Soon he will understand that he needs you. Then you will become a soldier again."

"Hungry," Marco just mumbled in response.

Jean hurried upstairs, pushing passed several different people. He ignored their comments about him being rude and just wanted to be alone to think about this whole thing for a second.

Once getting to his room he slammed the door behind himself, trembling as he forced back his tears.

"T-this is insane! Why is that bitch doing this?!"

"What bitch?"

Jean tensed and yelped slightly from being startled when hearing the other voice. He quickly glanced at where he heard the voice.

"Armin?" he gasped. "How did you get in here?"

"I just got here just now looking for you," Armin insisted as he looked at him. "Are you feeling okay."

"Y-yeah, I'm fine," he insisted and cleared his throat before crossing his arms, trying to look like he didn't just freak out before.

"Sure," he mumbled. "So, who is this 'bitch' that you are ranting about?"

He froze and sputtered as he tried thinking of a name. "T-that girl Sasha. She stole food again which means our dinner will be smaller than last night's."

"That sounds like something she would do," he simply replied, although he could obviously see that he was lying. "I'd better get going."

Jean stood in his place and watched Armin leave. Once he was gone he tensed up again as he went over to his bed.

"I want answers," he muttered as he glared slightly. "Obviously there is something wrong with Hartzfeld's motives. Something has to be wrong. If she is trying to bring humans back to life, shouldn't she make sure that they kept their personalities and morals as well? That would make much more sense, wouldn't it?"

He had to take to consideration that Marco had been dead for three months, now. So when narrowing that down, he didn't understand why he was acting so strange when he just went to visit him. Right now, Marco just resembled a mangled fiend that wants nothing to do with any experiences he had in the past.

"But despite all those changes that he went through, he still kept his interest in me…?" That was what really got to him. This new Marco still wanted to be with him like the way they had always been together before all of this happened. This was why he was now torn.

Should he return to being friends with him and pretend that nothing is wrong? Should he go against orders and warn others about what is going on so that he could be under surveillance? Should he develop any type of relationship at all with him again? Or should he just do nothing and just consider Marco's new existence an "experiment gone wrong?"

Only time will tell in this case, and he just hoped to himself that no one would get hurt from this horrible experiment.

Later on that night, two guards were told to investigate the basement. There were complaints of shrieking coming from down there, and this made even them concerned. No one was down there now that Eren Jaeger had his own living space. They had no choice though but to check it out.

With torches in hand, they slowly went around and looked at the different cells to look for anything suspicious. As they walked through, they were startled when the shrieks got a little louder.

"What is that?" the first guard gasped and looked at his companion.

"I don't know," he mumbled as the sound was getting nearer.

They both stopped once the shrieking did. None of them realized that they were right in front of the dreaded cell that the eerie noises were coming from. They glanced around nervously since they were tense.

In the shadows Marco waited, his eye narrowed and his face contorting in pain from hunger once again. He slowly stood up and moved closer, just as one of the guards looked up when hearing the noise. When the second looked up, they quickly took note that they were both mortified by this sight. They had their hands hovered over where their weapons were.

The first guard glanced at the second. "Go and quickly get back-up. We have to start this—A-ahh!"

His words were cut off quickly when Marco had reached his arm out of the bars after running toward them. He gripped the guard's throat and quickly pulled him closer, opening his mouth and quickly biting at the guard's face.

The second guard tensed and bit back a scream from fear as he watched his companion struggling and dying right before them. Then he remembered he needed to get help. He quickly ran down the hall.

"S-someone help! There's something evil down—!"

The next sound was a gunshot. The guard froze when feeling intense pain in his head for a brief second before lifelessly collapsing on the ground. A few yards away from him, Dr. Hartzfeld's eyes were narrowed since she had just shot the gun at the remaining soldier.

"You fool, I didn't want the secret getting out. It was a surprise," she muttered, grabbing the body's ankles and quickly taking him back over to the bars. Marco was too busy trying to devour the first guard hungrily to notice that she brought back more food for him. "This should hold you over until tomorrow," she assured him as she dropped the body near the bars.

Marco just nodded as he hungrily ate. He was full after a moment and abandoned his food, going over to the bed quickly and lying down.

"Tired!" he uttered.

"Good," she mumbled. "Now, get some rest. Your intelligent, little mind needs more time to develop."
