Eren and Historia were currently looking at map of a city, trying to figure out which way to go.

"It is a long way uptown. I think the subway's probably quickest." Historia suggested.

"Me in a metal tube, deep underground, with hundreds of people in the most aggressive city in the world?" Eren replied, not liking the idea.

"I suppose being with a large crowd of people around him wouldn't be such a good idea judging by how large this city is." Armin said.

"I wonder, is this subway a ways to get around the place faster? Must be very helpful to traveling, not like our underground cities." Hange said.

"Makes you think how many people live here." Jean said.

"For all I know, hundreds of thousands, maybe even millions." Armin answered.

"Seriously?! That's far more than the people inside the walls!" Connie exclaimed, shockingly.

"Yes, I know, its sounds unbelievable but that's my best estimate." He said.

"How high would the rest of the world be?" Eren asked.

"I wouldn't know, but maybe we'll find out one day." He smiled.

"One day." Erwin thought as he also wants to know about the rest of the world.

"Right, let's get a cab." She said, nodding.

The screen changed to a taxi car driving through the traffic streets recklessly as hip hop music was playing.

Most of the audience was shocked at what they're seeing.

"Come on, now! Let's go! You're too slow! You drive like a woman!" The driver yelled as he was passing through each car.

"Very nice. You see her?" Oluo said as he was revealed to be the driver.

"Oluo is the driver?" Eld commented, in disbelief.

"Yes, I get see my TV self." Oluo said, proudly.

"Somehow I'm not surprised." Petra groaned.

"Oh my." Historia gasped as they made a mistake for travel.

"Very pretty. Watch out, you goat!" Oluo shouted as he nearly ran a pedestrian over.

"Breathe, breathe, breathe." Historia told Eren, trying to keep him calm as his watch was beeping.

"What is he thinking?!" Historia exclaimed.

"He needs to get out of there." Armin said, worried he might transform.

"What's with this city?" Eren exclaimed.

Finally, the car stopped and Eren was the first to get out. Historia got out next and slammed the door.

"ARE YOU OUT OF YOUR MIND?! What is wrong with you!" Historia snapped, angrily as she went to the driver.

"What's the matter, baby? You don't like a good ride?" Oluo flirted then did a smooch expression.

Every girl in the room looked like they wanted to kill him.

"Is this how you talk to girls?" Ymir asked, glaring at him.

"Of… of course not. I told you, I'm a lot better in getting girls." Oluo said, proudly but was also hiding that he was intimidated by them.

"Oh, really." Ymir said, not convinced.

"That's an obvious lie." Annie said.

"What? It's true." Oluo defended.

"Why don't you tell us her name then?" Hange asked.

"Sure, let's see her name was… It was… oh, that's right it's- aggh!" Oluo accidently bit his tongue and bled again.

"Serves you right." Mikasa said, bluntly.

"Wished the other Oluo did the same." Petra muttered.

She couldn't believe what she heard then got pissed off as Oluo started driving away.

"ASSHOLE!" Historia yelled. She turned to Eren who was calming down with the watch stopping.

"You tell her!" Ymir shouted as many other girls agreed. Historia herself also supported it.

"You know, I know a few techniques could help you manage that anger very effectively." Eren offered.

"You zip it. We're walking." Historia told him, clearly not in the mood.

"Okay." He nodded.

"I've never seen her this angry before." Jean said, intimidated.

"Remind me not to piss her off. Oh and Mikasa too." Connie said, shivering as some other males thought the same except Levi and Erwin.

"I guess women are sometimes more scary than titans." Armin thought.

"I don't see what the big deal is." Eren said.

"Of course you wouldn't, dumbass." Jean responded.

"WHAT DID YOU CALL ME?!" Eren growled.

"Quiet, now." Levi told them.

"Yes sir." Eren and Jean immediately replied.

Later, people were leaving the building as Armin with a bag, doing the same. However, someone stopped him.

"Excuse me. Dr. Arlert?" Historia asked.

"Yes?" He replied.

"I'm sorry to bother you. I'm Historia Reiss." She introduced.

"Oh! Dr. Reiss!" Armin recognized as he was surprised.

"I have someone who'd like to meet you." Historia said.

"Okay." He replied, confused about who she wants him to meet. Eren with a hat on as cover stepped up and finally met the doctor he's been messaging.

"It's Mr. Yellow, isn't it?" Eren asked.

"Mr. Green?" Armin gasped, shocked in meeting him in person.

"They finally meet." Historia smiled.

"Hopefully, Eren can finally be cured." Mikasa said.

"I wonder how I'm going to cure him." Armin asked, curious.

"It could be after analyzing his blood and information, he looks for a way for the cause then starts developing the cure that would get rid of that cause." Hange said, in theory.

"I've got to tell you, I've been wondering if you were even real. And if you were, what would it look like?" Armin said as they started talking in an office filled with books and paper.

A person with that much… power lurking in him. Nothing could have surprised me more than this unassuming man shaking my hand." He ranted.

"A person turning into a titan. It's still so unbelievable." Eld said.

"Shaking a titan's hand." Hange said as the thought excited her. She couldn't resist to giggle about it.

Levi rolled his eyes as he heard her.

"But, look. We're not strolling into the park for a picnic, here. Even if everything goes perfectly, if we induce an episode, if we get the dosage exactly right, is that going to be a lasting cure or just some antidote to suppress that specific flare-up?" Armin said he started discussing about the cure. He snapped his fingers, doing a coin flip.

"I don't know." He shrugged. It was not helping either of them as they both shot a look at him.

"Just get to the point already." Ymir told him, annoyed.

"Is it going to cure me or not?" Eren asked, wanting to know.

"What I'm saying is that we overshoot this by even the smallest integer, we're dealing with concentrations with extraordinary levels of toxicity." Armin explained.

"You mean it could kill him." Historia concluded, not liking this solution.

"Kill him? Yeah. I should say so." He nodded. She took in this information, not sure if Eren should go through with this as she was worried about him.

"It could kill him?" Armin asked, worried.

"It's too risky. There has to be another way." Mikasa said.

"I'm not sure if there is." Armin said.

"You should know that there's a flip side to this, too. If we miss on the low side, if we induce me and it fails, this will be very dangerous for you." Eren warned.

"Maybe they shouldn't go through with this. What if they fail?" Sasha said, concerned.

"There may be a chance of it working though." Hange said.

"Still, it sounds really risky." Petra said.

"So is going up against titans and we do that every time we go on a mission." Levi said.

"I'm not sure if it would work but I say we do it." Eren said.

"If there's a smallest chance of success then it's worth the risk." Erwin said.

Armin laughed a little in response.

"Look. I've always been more curious than cautious, and that's served me pretty well. So, are we going to do this?" He said, still willing to go through with this.

"This Armin is actually willing to go through with this." Jean commented.

"Let's hope they succeed." Armin said.

It was night time at a military base as men were preparing helicopters and other vehicles, beginning their hunt.

"Great, Reiss's men are already ready to move and look for Eren." Ymir said, annoyed.

"They better not interrupt me in the middle of it!" Eren growled as his other self was getting so close.

"I hope they hurry and show us the procedure already." Hange said, impatiently.

Reiner was in a locker room alone, shirtless. He was staring at the mirror, seeing the difference about him after having more of the serum in him. His back revealed to show his spine growing as it was going to break out.

"That's disgusting." Historia said, grossed out as other audience members felt the same.

"Is this the effects of the serum?" Bertolt asked, surprised by Reiner's appearance.

"Must be. Could be strong enough to fight against Eren's titan this time." Reiner said.

"But does he have control of it?" Armin asked.

The screen flashed to Reiner approaching to the helicopter with a submachine gun in hand. Many soldiers along with General Reiss were in the helicopter. He sat down on an empty spot and the helicopter started to take off.

"How you feeling, man?" The soldier in front of him asked.

"Like a monster." Reiner grinned, eager to face the Hulk again.

"I knew this was going to happen." Levi said.

"Does Reiss not know about Reiner's condition?" Jean asked.

"He's hiding just so he can fight Eren." Armin answered.

"Reiner." Bertolt said, concerned about his state while Reiner himself is curious if he's going to get the chance to fight the Hulk again.

Armin uncovered the plastic wrap and threw it away, revealing a strap chair. He set the chair up then started up some old computers and equipment.

Eren and Historia walked into the room seeing what Armin was doing. He attached a purple colored glass container on the machine. He turned and faced Eren.

"Okay. On the table." Armin told him.

"Good, they're getting started." Hange said.

"I hope you can survive it, Eren." Mikasa said, worried.

"I'm sure he will." Jean scoffed.

"These will protect you from yourself if you have a strong reaction." He said, as Eren was shirtless with Armin putting straps on him and attached to wires and tubes.

"Those won't hold him. He'll break through eventually." Armin said, wishing his other self would be more prepared.

"I hate that Armin and Historia are going to be in danger because of me." Eren said.

"We can only hope it goes a success." Hange said.

"You can tell me later if you thought it was strong." Eren replied.

Historia was helping by putting the last restraint on Eren. The machine was starting to power down and had some malfunctions.

"Oh, come on! Stupid graduate students." Armin said, hitting the machine. He moved to another computer as Eren and Historia stared at each other.

"Using malfunctioned equipment for this? That's not a smart thing to do." Ymir said.

"Doesn't look like he has a choice. They have little time to cure Eren and they can't look for proper equipment needed." Armin said.

"Defective or not, there's no excuse for it. Keep in mind that your gear is in check." Levi said.

"It's a one way chance for this operation." Erwin stated.

"Okay… You. You. You." Armin muttered, turning each of the equipment on. Historia stood by Eren's side, giving him comfort.

"This will be a somewhat novel sensation. We have begun." Armin said as the machine powered up and started the procedure. Eren was feeling tense and the tubes were being filled with blood.

Mikasa and Historia took deep breaths as they were tense to the outcome.

"The dialysis machine will mix the antidote with your blood. Except the antidote will only take hold once we've achieved a full reaction." Armin explained.

"Just relax." Historia said, softly.

"Okay. We are comprehensive. Here you go." He said as he grabbed a case and gave it to Historia. She took it out and placed it on Eren's mouth to bite on.

Armin had some type of metal tools and was about to place it on Eren's head.

"All right. We set to pop?" He asked. Eren glanced at Historia.

"Let's get it started." Eren said, hoping his other self gets cured.

"I'd take your hands off him." Armin advised. Historia complied and let go of him.

"Rather try to get ten feet away from him." Ymir told her.

"He might need me to keep him from leaving." Historia said.

Armin activated the tools which had an electric spark then placed it on Eren's head. A moment later, he took it off and Eren was feeling the pain as he struggles. His eyes started to glow soon after then was starting to change.

The rest of the audience has grew tense to the operation. Eren watched the screen closely as he was unaware that his hands were held by Mikasa and Historia as they were worried.

"Oh, my god!" Armin said, amazed as Eren was turning.

Eren spat out the bite piece and his muscles started to grow and turn green while in pain. Luckily, the straps were still keeping him down for now. Eren was screaming in the middle of the procedure as his transforming continues. Armin was about to quickly do something.

"Wait, wait! There's more! Wait!" Historia stopped him.

"Why wait?! Why don't they do it now?!" Connie exclaimed.

"The transformation has to be complete in order for the antidote to work. In other words, the most dangerous he is, the better chance for it to work." Hange explained.

"Armin is going to have be really quick to give him the cure." Moblit said.

They continued to watch Eren changing back into the Hulk, the wires on his head fell off as he's starting to break free from the restraints. Armin was shocked to what he was seeing.

"Now. Okay, Now!" Historia told him.

"Wait." Armin said, wanting to see more. The Hulk was about to break free from the straps.

"Quick! Give him the cure!" Sasha shouted.

"She told you now!" Connie exclaimed.

"He's starting to get free!" Petra panicked.

"Now, do it! Do it!" Historia cried.

One of the straps broke and hit Armin. He fell on the floor, and saw how powerful the Hulk was becoming as the metal below the chair was being crushed. The Hulk was close at being free until Historia go on top of him to calm him down.

"Come on, Armin! Get up!" Eren shouted.

"Hurry and inject the antidote!" Armin exclaimed, tensely.

"Eren!" Mikasa said, worried.

"Eren! Eren, look at me. Stay with me." Historia said softly, trying to keep him calm and preventing him from being free.

"The antidote, now! Armin, do it now!" She told him, looking him in the eye. He complied and was working on the antidote. She turned back to the Hulk.

"Stop screwing around, Armin!" Ymir shouted.

"Please hurry!" Historia yelled as she's not sure how long she can hold him.

"Eren, look at me. Look in my eyes. Please look in my eyes." Historia said softly. The Hulk was looking at her but was still struggling to break free.

"Oh, you've got to be kidding me!" Armin complained as the computer was beeping in error.

"Really now?!" Jean shouted.

"This is not the time!" Eren yelled.

He ran to the antidote machine and kicked it. Surprisingly, it worked and the antidote was being injected in the Hulk.

The Hulk's eyes were going back to normal and was groaning. Armin checked the status of the computers.

The audience was starting to ease their tensions as the worse has past.

"Eren." She said, hoping he's okay.

"Oh, my god." Armin gasped, looking at the results.

"What is it? Show me what's on that computer thing." Hange said, eagerly.

Eren's skin was turning back to normal and was changing back.

"Eren? Eren, can you hear me?" Historia asked, hoping that he's still alive. There was no response.

"Eren." She said, getting really worried.

His eyes opened and gasped for air as he woke up. Eren tried to look around only to be stopped by Historia as she grabbed his head.

"It's okay. You're okay. You're okay. You did it." She assured, relieved that he's alive. She had her hands on his cheeks in care.

Mikasa and Historia sighed in relief.

"It worked. The other me is cured." Eren smiled.

"Congrats, Eren!" Hange cheered.

"Yes, it worked. He should be cured from the titan." Armin said, unsure. He didn't know for sure if it worked or not.

Erwin noticed his expression as he also wants to know if the antidote was a success.

"He's fine. This is fantastic." Armin commented amazed, looking at the computer screens.

"It's over." She told him as their faces were close up.

"Hi." Eren said.

"Hi." Historia replied.

"Are these two ever going to stop flirting?" Ymir asked, annoyed.

Eren and Historia turned red as they had to see these moments again.

The next scene changed to military helicopters flying over the city as police sirens were heard.

"That was the most extraordinary thing I have seen in my life!" Armin exclaimed as the three were back in the office.

"I know, right!" Hange exclaimed.

"Great, I'm seeing four-eyes in this Arlert." Levi said, annoyed.

"Hey Armin, have you thought about helping me with research sometimes." Hange asked.

"I'm not sure if I'm up for that." He answered.

"Arlert's intelligence is more suitable for tactical strategy and perception rather then research." Erwin stated.

"Okay, you know what? Stop please. We need to go back and talk about what just happened in there." Historia said.

"Absolutely. Okay. The Titan pulse came from the amygdala." He started to explain.

"Are you okay?" She whispered to Eren.

He nodded.

"I think Dr. Reiss's primer lets the cells absorb the energy temporarily and then it abates. That's why you didn't die of radiation sickness years ago!" Armin explained.

"Interesting, so it's like Eren's blood accepted the titan poison in him and allowed his body to transform into what he was." Hange said, writing the details down.

"Now, maybe we've neutralized those cells permanently or maybe we just suppressed that event. I'm inclined to think the latter, but it's hard to know because none of our test subjects ever survived. Of course, they weren't getting the primer." He continued.

"Wait, wait. Wait, what did you just say?" Eren interrupted him, hoping he hadn't heard him right.

"They weren't getting the myostatin primer…" Armin said.

"No, no, no. Test subjects? What test subjects." He asked.

"Wait, test subjects?" Historia asked.

"Not human test subjects, right?" Connie said, hopefully.

"He could referring to animals such as rats or mice for example. Doctors had to test their drugs on something to see if their cures worked." Hange explained.

"Those poor animals." Sasha said, sadly even though she hunts them.

"Come with me" Armin answered with a happy expression as he began to lead them.

Outside of the building, police cars and military vehicles were stopping in front of it. Reiss got out the humvee he was in then walked towards the command vehicle and got in.

"The military is already here." Gunther said.

"If that cure actually worked, Eren may not escape this time." Eld said.

"What's the activity level?" Caven asked.

"Snipers are covering Alpha sector." The soldier reported as he's watching the monitors.

Snipers were watching the three inside the building through the windows and listened in their conversation.

"They don't know Reiss and his men are here." Armin said, fearfully.

"These people come at the worst time!" Eren complained.

"That's the point. They want to catch you off guard." Ymir deadpanned.

"We started on rats and mice, but it just completely fried them, so we had to go bigger. And we still don't know which is more toxic, the titan or your blood." Armin stated as they enter a room full of blood bags on both sides.

"How much blood did Eren send?" Historia asked, shocked.

"It's not possible." Mikasa said.

"How could all of this be mine?" Eren gasped.

"He would have run out by then. Unless…" Armin said.

"Unless Armin had to create more of them." Hange said.

"How could he make more?" Jean asked.

"My guess is that once Armin obtained enough blood samples from Eren, he was able to replicate the blood cells then create more to test it." Hange explained.

"What do you mean my blood?" Eren asked.

"Eren, this is all you. You didn't send me much to work with, so I had to concentrate it and make more. With a little more trial and error, there's no end to what we can do! This is potentially Olympian!" Armin explained as Eren looked around and examined the bags of his blood.

"This titan technology has limitless applications. We'll unlock hundreds of cures. We will make humans impervious to disease!" He stated.

"He wants to make the titan serum into a cure for diseases?" Petra asked as it sounds crazy.

"That's ridiculous, who would use titans as a cure?" Jean said, in disbelief.

"It does sound tempting and it could help develop immunities to poisons. But when you look at the risks it has, it may cause more a lot harm than good and create titans like Eren's." Hange said.

"This could be what Reiss is looking for." Armin said.

"They have to get rid of it. All of it." Eren said in a serious tone.

Two Humvees parked in front of the stairs and soldiers got out of them with weapons ready. They enter the front doors as Reiner was in front. He had his men secure the area.

"No, no, we've got to destroy it." Eren said, back at the office.

"Yes, do it. Quick." Eren agreed.

"There's no time. The military could step in at any minute." Armin said.

"Wait, what?" Armin said confused.

"All of it. Tonight. We're gonna incinerate it. Is this the whole supply?" Eren asked.

"What? We could get the nobel for this!" Armin exclaimed.

"You don't understand the power of this thing. It is too dangerous it cannot be controlled."

"At your discretion, shooter." Caven said through the comms.

The sniper had his rifle aimed at Eren through the window. But still couldn't get a shot yet.

"…three of us! This is promethean fire!" Armin said, trying to reason with them.

"It's just…"

"No shot." The sniper stated.

Reiner heard then decided to go in and head upstairs to their floor to face Eren.

"He's not wasting any time going in." Gunther said.

"I didn't hear any orders he gave him." Petra said.

"He doesn't care. Reiner's going to try to fight that Hulk again." Ymir said.

"I'm not going to get another chance." Reiner said.

"Reiner's going in." Caven told Reiss.

Reiss stepped closer to the computers, wondering what he's doing.

"Reiner, stand down. My daughter's in there!" Reiss ordered.

Reiner ignored them and continued going up. He jumped up to a few floors, trying to get there faster.

"He's lost control. They need to take him off the team." Levi stated.

"If only I still had my power to take him down." Eren growled.

"We have the antidote now!" Armin said.

"They don't want the antidote! They want to make it a weapon!" Eren exclaimed.

Reiss quickly got back into the Humvee and it began to drive closer to the building.

"And if we let it go, we will never get it back. You don't know how powerful this thing is." Eren continued.

"Hurry up and destroy it." Connie exclaimed.

"It's too late." Ymir told him.

"I hate the government just as much as anyone, but you're being a little paranoid don't you think?" Armin said.

The sniper had a clear shot as Eren was in front of the window and fired.

The dart hit him in the back as Armin gasped out of shock. Historia quickly held to him up and pulled out the tranq dart. Eren fell to the floor, tired.

"Eren!" Mikasa cried.

"Dammit!" Eren cursed.

"Eren! Eren!" Historia said, trying to keep him awake.

"Get out." He said as he saw Reiner entered the room.

Historia was in front of him but he threw her out of the way, making her crash to a glass cabinet. Reiner grabbed a hold of Eren, aggressively.

"You ass!" Ymir shouted.

"Damn him!" Eren growled.

"This is not how you treat a girl you like." Reiner thought as he didn't like to hurt Historia. Though he wasn't sure if it's from his soldier persona or not.

"Where is it? Come on, where is it?" He demanded. Eren's watch started beeping. He slapped him a few times to try to make him change.

"Show him to me." Reiner demanded. Eren was still not changing.

"Did it… Did it work?" Jean asked.

"He is isn't changing." Historia said.

"Some part of me is hoping it didn't so Eren could tear him apart." Mikasa

"Reiner!" A soldier called as he rushed into the room.

The watch went off but it he didn't change. Reiner decided to knock him out and the screen went black.

"It really did work." Bertolt said as he saw that Eren didn't transform.

"Eren's life going to be endanger without his titan." Mikasa worried that he'll be killed.

"If only I had time to get away." Eren groaned.

"At least Reiss won't get Eren's titan." Armin said.

"Still, this Eren deserves a normal life. My father just had to ruin it." Historia said.

Soldiers were leaving the building with Eren strapped to a stretcher. Historia was behind him as she followed.

"Miss." A soldier stopped. She turned and looked at him.

"Take this." He said, putting a coat on her.

Reiss looked at Eren, face to face.

"If you took it from me, I'm gonna put you in a hole for the rest of your life." Reiss threatened.

"I hope you get nothing out of it, you bastard!" Eren growled in anger.

"I'd kill him if I got the chance." Mikasa said, angrily.

He let them continue taking Eren to the helicopter. Historia was following but was stopped by her father.

"Christa." He said.

She looked at him with disgust.

"I do not want to talk to you." Historia hissed.

"I will never forgive what you've done to him." Historia said.

"He's a fugitive." Reiss stated.

"You made him a fugitive, to cover your failures and to protect your career. Don't ever speak to me as your daughter again." She said.

"He also wanted to make Eren into a weapon." Mikasa said, glaring at him.

"It truly can be unfair to become a criminal against your will." Armin sighed, sadly.

"We'll all become fugitives soon enough." Levi said.

"What do you mean? We haven't done anything yet." Connie said, confused.

"Don't forget that we've been hiding Eren and Historia from the government, not just the titan shifters. As soon as they found them, they'll want us to turn them in and we can't afford that to happen." Hange explained.

"In other words, an inevitable Coup D'état is bound to happen if we want to uncover the truth." Erwin finished.

"It's only because you're my daughter that you're not in handcuffs, too." Reiss said.

"At least he cares about his daughter." Jean said.

"And that's supposed to make me feel better?" Historia scoffed.

Historia turned and continued heading to where Eren was.

The screen switched back to Armin's lab.

"Are you telling me you can make more like him?" Caven asked, interrogating him.

"Can he?! Can he make more like Eren" Hange said with curiosity.

"We focus on killing them, not making more." Levi said.

"No! Not yet. I sorted out a few pieces, but it's not like I can put together the same Humpty Dumpty, if that's what you're asking." Armin answered.

"He was a freak accident! The goal is to do it better!" He explained.

"So my other me wants to make an improved version of Eren's titan. So he needed the titan data and Eren's blood to try to finish his research and create it as a cure." Armin said.

"If only we had the chance to destroy it." Eren said.

"So Yeager's the only…" Caven said but was suddenly knocked out by Reiner.

"She's an annoying bitch." Reiner said.

"What? What's he doing?" Bertolt asked, shocked as Reiner was also wanting to know.

"He attacks his own soldiers now?" Jean asked, in disbelief.

"Why doesn't this betrayal surprise me?" Eren commented.

"Why are you always hitting people?!" Armin asked.

Reiner raised his pistol at Armin.

Many of the audience were surprised at Reiner sudden betrayal.

"Now what possibly could I have done to deserve such aggression?" He asked.

"It's not what you've done. It's what you're gonna do." Reiner answered.

Armin was confused for a moment.

"I want what you got out of Yeager. I want that." He demanded.

"Is he insane? He wants more of that stuff!" Connie exclaimed.

"Why? He's already caught Eren." Sasha asked.

"He's becoming power hungry. He wants to be stronger than Eren's titan." Armin answered, in fear.

"Now I really wished I killed him." Eren said, regrettably.

"And I thought this other me was a soldier but he's not, at least not anymore." Reiner thought.

Armin slowly stood up as he was interested.

You look like you've got a little something in you already, don't you?" Armin asked.

"I want more. You've seen what he becomes, right?" Reiner said.

"I have. And it's beautiful. Godlike." He nodded and commented.

"That serum made him worse than I thought." Levi said.

"I can't imagine what's going to happen if he has Eren's blood in him." Armin said.

"Well, I want that. I need that. Make me that." Reiner repeated.

"I don't know what you've got inside you already. The mixture could be an abomination." Armin explained.

"What does Armin mean by abomination?" Connie asked, nervously.

"It could mean that it may not turn out well. His body might mutate and may not have any control of it at all." Hange said, in theory.

"This is so bad." Armin said, fearfully.

Reiner decided to lift him high with his strength, clearly not liking his answer.

"I didn't say I was unwilling. I just need informed consent." Armin said.

Reiner held him closer as a threat.

"And you've given it." He continued.

"No, don't give him the blood!" Eren shouted.

Mikasa wanted to end Reiner there for threatening Armin and wanting to kill Eren.

"Please don't do it, Armin!" Sasha exclaimed.

"It doesn't look like he has a choice since he's threatening him." Jean said.

"He's going to get killed ether way when Reiner transforms." Hange stated.

"I get the feeling my other self wants to know what Reiner's will turn into." Armin said.

"What? Why?" Eren asked.

"Scientific curiosity. They get too close on testing things that are too dangerous and it gets them killed for it." He explained, grimly.

"I know what it's like. I had keep the section commander from getting too close to her subjects." Moblit said.

"Come on, Moblit. I'm not that bad am I?" Hange defended. "Still, even I wouldn't go that far to create an experiment too dangerous for curiosity."

The helicopter took off as it was about to leave the city. Eren was sitting in front of Historia as they look at each other. She placed her foot on top of Eren's. He smiled in response.

She grabbed his hands and Eren kissed them, trying not to worry.

"Do you do that everywhere you're at?!" Ymir complained.

"I'm sure he doesn't want me to worry." Historia defended.

"Eren, this is not something you should do while being captive. You need to focus on escaping." Mikasa told him.

"I keep telling you, I don't like her that way!" Eren protested.

Armin placed a sample of Eren's blood on the machine and got it set up. Reiner was lying on the chair, waiting for the injection.

The machine moved in front of Reiner's face as it was bright then he started to transform. Computers were malfunctioning and growling was heard.

Many of the audience were shocked at what they're witnessing.

"Oh, god." Petra gasped.

"He's becoming a titan." Jean spoke.

"Reiner." Bertolt said, worried that he doesn't have any control of it.

"I feared it was going to turn out this way." Armin summarized as he was tense.

"Eren is going to need his titan to kill Reiner's." Eld said, as he knew the situation was bad.

"But how? He got rid of it, so he can't change into his titan." Connie asked.

"Maybe… just maybe… but I don't know for certain." Armin thought as he thought about a slight possible theory about Eren.

"This is what I was trying to explain. I don't know what you've been ladling into yourself. But clearly it worked." Armin said.

He stood back as Reiner got out of the chair with his clothes ripping off and turning tan.

"Let's assume, you don't understand a word I'm saying, but if you'll just get back on the table, I can fix this." Armin said, feeling threatened while trying keep his confidence.

"He's not going to listen." Levi told him.

"Armin!" Eren/Mikasa cried.

"Get out of there!" Sasha shouted.

Reiner kept growing as he grew spikes out of his back and was turning in to something similar to the Hulk, turning into the Abomination.

He attacked Armin and he crashed into a machine. Eren's blood sample was leaking and was going to drip to the floor where Armin was. The Abomination can be heard laughing.

The blood landed on Armin's head where his injury was. His head mutated a little. Soldiers can be heard trying to fight it off. Armin could only smile at his work.

"Great, now we're going to have a titan rampaging the city." Jean said, sarcastically.

"Who know how many people are going to get killed." Ymir said.

"Too many to count, the only hope is my father's men." Historia said.

Reiner wasn't sure what to think as he saw himself transform and was about to cause chaos in the city. Part of him felt guilty for this, the other part felt he was doing what had to be done as a warrior.

"That won't be enough. They'll need Yeager for this." Levi said.

"I knew my blood was too dangerous! Now's it's infected him!" Eren exclaimed.

"Don't tell me it's going to turn him to a monster too." Connie complained.

"I wouldn't think so since Reiner had the serum in him. But I could guess he's having a different mutation." Hange said

"I don't know why my other self is smiling about this. Do I really enjoy making Reiner into that?" Armin said, as he felt disgusted about this.

"It wasn't you, Armin. You're not a scientist insane for knowledge, you're our friend." Mikasa told him, giving him comfort.

Armin smiled as thanks and nodded.

"I need my power back." Eren said, wanting his other self to stop him.

The audience was tense, as the upcoming battle between Hulk and the Abomination was about to begin.
