"I'm giving the injection to Erwin." Levi had stood in front of Eren and had ultimately made up is his mind.

"Tch!" Eren angrily got up into Levi's face. Bubbles of water had formed into his eyes. "You said that you were going to use it on Armin…" he protested.

"I will give it to the one who will save humanity." Levi told Eren.

"What?"

Floch stood there watching this all go down, then he noticed Mikasa had drew her blades and begun to approach the captain. Levi looked from behind and saw Mikasa approaching him with her blades. He then turned forward to Eren.

"Move, Eren. That's an order." Eren refused to budge an inch and grabbed the injection he then started thinking of this is insubordination. "Do you two have any idea what you're doing? It's Commander Erwin we're talking about. The leader of the Survey Corps. And you're telling me to watch him die?" Levi then looked up to Eren. "Eren. The Commander brought into the Survey Corps because he believed you can reveal the truth of this world." Levi sees that Eren would still not let go of the injection. "Eren. Put aside your personal feelings, for once. This is bigger than you. Bigger than Armin too."

"Bigger… than me? Are you joking? Tell me… why did you wait so long just for Floch to give you the injection?" Eren asked.

"I had a haunch that Erwin would still be alive." Levi answered.

"A haunch? There's no way you would've known that Floch would've carried Erwin up here on his back."

"You're right, I didn't. But now that he's here, I can give it to him. And that is final." Eren clutched his hand onto the injection. "This is your last warning… move." Levi warned with the glare in his small pupils.

"With all do respect, captain. But no." Eren replied. Levi sighed then backhanded Eren with his left fist, knocking a few of his front teeth out and sending him flying to the edge of the roof. "Ugh!" Eren made thud with the roof face first.

Mikasa gasped as she saw Captain Levi assault Eren. Enraged by it, Mikasa charged in and tackled her superior to the roof back first. "Arh!" Mikasa screamed. She then placed titan killing blades over his throat with one hand and tried to grab the injection with the other. This exhausted Levi tried to wrestle his way out, but he was too fatigued. The young female Ackerman was too strong for him.

"Hey!" Floch yelled.

'Shit! I'm out of strength!' Levi noted.

Mikasa pinned Levi's arm to the brown tiles. 'He's out of strength to stop me! I can just take it by force!' Mikasa noted.

"Hey, Mikasa. You two brats know just as well as I do that the Survey Corps can't survive without Commander Erwin. We can't beat the titans!" Levi said calmly as he continue to struggle.

"He's right, Mikasa. Stop this nonsense right, now." Floch took one step and Mikasa turned and growled, which caused Floch to flinch for a second.

Eren's left arm and head was hanging off the edge of the roof. "No… we can't survive without Armin either."

"Eren!" Mikasa called.

"If Armin dies… we can't beat the titans!" Eren had struggled to get up from the edge. "Back in Trost District, he came up with a plan for me to seal the breach… then he discovered the Annie Leonhardt's true identity… he came up with the idea to start the expedition at night… he was able to locate Reiner's hiding spot… and he was the reason I was able to defeat Bertoldt! It was all Armin! If anyone can save humanity, it's him! We owe our lives to Armin! Neither I nor Commander Erwin could save humanity… it will be Armin! Right, Mikasa!?" He screamed as tears ran down Eren's face and blood ran down his chin as he started crying.

Mikasa turned her attention back to Levi. "Please, let go." She asked nicely.

Floch stepped forward. "The one who will save humanity… is Commander Erwin." Floch protested.

"Shut up!"

"No. I will not. Do you think you're the only one suffering?" Floch had begun informing everyone with his speech. "You may not know this but… not a single soldier out there is alive! They were all wiped out by the Beast Titan, by a bunch of rocks and the titan tore them to shreds. The grass on the other side of the wall has been stained with the blood of my comrades. No one believed that they were going to live against the Beast Titan. Not even the commander, himself. He led us all to hell so that Captain Levi could put an end to him… I'm sure the last thing they all felt… was fear. I still question myself why only I have survived…" Floch had remembered that he survived unharmed.

"When I found out that Erwin was dying, I was about to finish him off." Levi, Mikasa and Eren continued to listen to his story. "But then I realized that I would only be giving him mercy. I then thought to myself… he's not done when it comes to this hell. And then I understood…" Floch watched Levi kill the titans, so he withdrew his blade and took Erwin to safety.

"The only who could destroy the Titans… is a devi! Someone from out of this world! That is my mission. To bring the devil back to life! That's the only reason a coward like me survived." he turned to Mikasa. "So please… Mikasa." Floch charged towards her. "Don't get in his way!"

"Ngh!" Mikasa grunted as saw Floch coming, so she readied herself as she was prepared to slash Floch with her blade with killing intent.

Levi saw Mikasa's killing intent and she knew she was going to strike Floch down. "No! Don't do it!"

As Mikasa was about to strike, she grunted and felt herself suddenly grappled from behind by an one-eyed Hange Zoë.

"Hange!" Levi cried out.

"Gah!" Mikasa continued to struggle until Hange used her wait to pull Mikasa back. Jean with bandages wrapped around his shoulder and Connie with a comatose potato girl on his back, named Sasha Blouse.

"No way… don't tell me…" Jean begun to say.

"What the hell? Is that?" Connie's eyes widened in horror.

Hange gasped as her one eye shot in horror. "Good god… what happened here?" Hange stared at the bodies of a bleeding Erwin, a roasted Armin and a knocked out amputated Bertoldt Hoover. She then knew what was happening. Only one of her comrades were allowed to receive the titan injection.

Mikasa gasped as Levi opened the injection and grabbed the needle as he looked at Erwin. "Ah!" She began to holler out in grief.

"Mikasa! I know how you feel, but we still need Erwin! The Survey Corps is nearly wiped out! If the commander dies, then we lose our symbol! We can't let the Flame of Hope in the wall extinguish!" Hanji tried to reason with the girl.

"I know, but Armin can be that Flame of Hope, too!" Mikasa yelled back.

"Listen to me. Armin is remarkably talented… but our fight is far from over! We need someone like Commander Erwin's leadership and experience an—" Mikasa squeezed Hange's hand in anger and grief. "Urgh!" she groaned. "I have people I wish I can bring back too, you know. Hundreds of them."

"What?"

Hange then reminisce about Bertoldt's transformation and explosion that was less than an hour ago. "Ever since I join the Survey Corpse, I have had people die on me everyday. In the end, everyone you know is going to die sooner or later." Hanji had embraced Mikasa. "I get it. It's painful… it's dreadful… it's hard to keep your sanity in all this… it's something we have to endure… it's something we call life. It's a cruel world and you only live once. It hurts… it's painful. The only thing we can do now is to keep moving forward from that pain." Hange had finished her speech.

Mikasa turned back to look at the Section Commander's face, then looked Levi whom had filled the needle with titan serum. Mikasa had looked at the sky and visualized Armin one more time before making peace with herself. She closed her eyes and had finally let go of Hanji's hand in grief.

Levi had squirted a little bit of serum out the needle just to see if it worked. Before he could move towards his superior Erwin, Levi felt someone grab his left ankle.

"Captain…" he saw that Eren had grabbed his ankle at the last second. "Have you ever heard of the ocean? It's like a giant lake, but it stretches pass the horizon… but all of it is made from saltwater. That's what Armin said.

"Stop wasting time, Eren!" Floch pinned Yaeger down face first.

"He told me there was an ocean beyond the walls… and that we would see it one day… But I forgot about that dream along time ago, until recently… Avenging my mother… killing all the titans… my head was clouded by hatred." Eren began to whimper. "But he's different! Armin's nothing like me! He had dreams too! He cares about more than fighting… so please, captain… Give the injection to Armin! I beg you!" Eren screamed.

Levi had heard what both Eren and Mikasa had to say and became the judge of it all. He closed his eyes and then looked back at everyone. "Everyone! Get out of here! I'm gonna have Erwin eat Bertolt in this spot! This is your final goddamn warning!" Levi yelled.

"Let's go, Mikasa." Hange helped her up and moved to a safe place.

"Goddamitt…" Jean muttered, before ziplining with his 3D Maneuver Gear.

Connie let out a stream of tears for Armin before ziplining away to safety. "Goodbye, Armin. It was nice knowing you."

Floch had carried Eren and ziplined away with his 3D Maneuver Gear. 'Armin…!' Eren had reached his hand out in the full extent towards Armin. 'This can't be happening… Armin!'

After everyone left, Captain Levi dragged Bertolt's body to the opposite side of the roof from Erwin and Armin. "Good grief. People going on about dreams, like children. Grow up." Levi muttered. He bent down and grabbed Erwin's left arm, and wasted no time injecting the serum into Erwin's veins. Levi had finally got what he wanted.

He left Erwin's body on the roof to transform and then grabbed Armin's burned body and ziplined to safety. He looked back at Bertolt, who was still recovering from his arms and legs being amputated. "Serves you right, you bastard."

Minutes later, Bertoldt was still unconscious. Suddenly, his eyes fluttered slowly. He heard a rumbling noise and it causes him to wake up. "Mmph." He moaned. "Huh?" Bertolt had fully opened his eyes to see a mindless titan tearing part of the house apart in order to get to him. This mindless titan was yours truly.

Erwin Smith.

Erwin was an 10 meter titan and he looked angry. He had widened blue eyes and still his same old eyebrows. He had a bit of sideburns going down to his cheek, a golden beard and his blonde hair was messy and spiky.

"Eh?" The mindless Erwin had grabbed the amputated Bertoldt with the full extent of its hand. "Ah!" Bertoldt screamed as the mindless Erwin grabbed him. Bertoldt tried to kick, but he had no legs to kick with. He tried to push out of Erwin's grasp, but he had no arms. He continued to squirm with his body until he saw his former allies and lightly smiled. Bertoldt still had a small ray of hope for them to save him. "G-guys! Please! Help Me!" Bertoldt pleaded with them to save his life, but what Bertolt saw sadness, anger and grief on their faces. He then knew he was going to be eaten. So he tried to call out to his two missing allies. He continued to scream until Erwin had placed his head into his mouth. "ANNIE! REINER!" And just like that, Erwin's teeth had munched down and bit off Bertoldt's head, leaving blood splatter on his chin and feasted on his body.

Meanwhile, Eren and Mikasa were left to mourn the loss of their best friend Armin Arlert. Eren reminisced about their childhood up until this point. He even remembered looking at a book with Armin as kids. "Armin… I'm sorry… I couldn't save you... Because of me… you never got to see ocean! I mean, how can you see it now when you're dead!" Eren clutched his fist and sobbed onto Armin's singed corpse while Mikasa stood behind him.

'Armin…' Mikasa couldn't hold back her sobs more than Eren could, so she clutched her left arm and started crying.

"Dammit, if we only had two or three injections, none of this would've happened… we could've saved both of them!" Jean said as he let tears out for Armin.

Hange felt a bit sadness and watched the remaining one hundred and fourth Cadet Corps. grieve over the loss of Armin, while Levi and Floch continued to watch Erwin feast on Bertoldt's body.

"It's done." Levi said.

"We did it. We've brought back… a devil." Floch rejoiced.

Erwin's body had finally collapsed to the ground face first after eating Bertoldt Hoover. Suddenly, a lot of steam bursted and his titan body had evaporated. "He's turning back to normal! Quick! Hurry!"

Hange, Levi and Floch had ziplined over to him. It was a moment of silence as the Survey Corps. cadet, captain and section commander had watched their commander Erwin transform back into a human. Erwin was neither human or a titan. He is now… a Titan Shifter. And he has his right arm again.


Author's Note : Hello everyone, this is my first what if story of Attack on Titan. I've wanted to do this fanfiction. Too be honest, I was looking forward to seeing Erwin with two arms again, but it never happened. Don't get me wrong, I did like Armin as a character. It was still sad to see Erwin go. He would've been so happy to see Grisha's deep dark basement.
