Izan couldn't take anymore of Hellflix's Demonic grin and said "alright, you can stop grinning at me like that. Just tell me what you want", Hellflix spoke "I need you to help me get past the final wall". Izan thought about it and concluded that for once something that didn't involve much bloodshed... other than the titans there was no other fighting needed, Izan responded to Hellflix's request "sure, let us shake on it" Izan extended his hand and Hellflix shook it.
Hellflix turned his head in the direction of the walls, although he could not see it he knew where it was. Hellflix spoke "we'll arrive there by nightfall if we leave now", Izan nodded his head in understanding. Hellflix put on his large coat and took one of his spiked brass knuckles in case he needed to transform into a titan. They climbed down and Hellflix called his horse. When the horse arrived they each got onto their horses and rode toward the wall.
It was early sunset and Mikasa and Eren sat in the room they shared. They were eating their final food ration for that day when there were some soldiers running toward the gateway with their rifles in their arms. Mikasa heard the gateway opening but showed little concern until a name she knew too well was announced in the following sentence "Izan Bronze, you are to be taken into the custody of the Military Police Brigade for deserting, if you resist, I have the authority to kill you on the ground you stand". Izan saw Mikasa in the corner of his eye. She was standing half way out of a door and the fact that she wasn't moving made Izan conclude that she might be in shock. Izan looked back and saw his cousin ready to punch his own hand with his spiked brass knuckles.
Izan knew there were only two choices: he could fight against them and he might live slightly longer or he could submit to them and the verdict would be decided later. Then Eren looked outside a window and saw Izan raise his hands into the air. Two of the many soldiers there ran to Izan and Hellflix and shackled them. Izan and Hellflix were then taken to the dungeon while Mikasa and Eren watched.
A couple hours had passed and Izan was in his cell along with Hellflix. Strangely they were both in the same cell where all the other cells only had one prisoner. They were being watched by two soldiers armed with rifles. Izan wanted to see how these soldiers would react to some chatter. Izan spoke to Hellflix "hey Hellflix… I wonder how we could escape the dungeon; this place doesn't seem too locked up". Hellflix understood what Izan was doing so he responded "yeah, I say there's only about ten soldiers in here we could break out of here with ease. Do you still have that spoon" one of the soldiers hit the bars of the cell they were in and yelled "SILENCE". Izan and Hellflix laughed at the soldier causing the soldier to become angry. The soldier yelled at them "SHUT UP", Izan spoke after he finished laughing "alright we're sorry… we'll be quiet now". Hellflix rested himself onto the bed and quickly fell asleep after being bored for five minutes; Izan on the other hand was waiting curiously to see if he would get visitors.
After ten minutes Izan was about to give up hope, but Izan heard a metal door scrape against the cold concrete floor. Then several footsteps led to the cell he was in, Izan focused on the person's face and realized who it was… it was Levi. Levi spoke to the Soldiers who stood guard "I have the permission to interrogate them. Leave me to my work", Izan stood up off the bed watched as the guards left the hallway and asked Levi "what do you want to know". Levi then responded "why you deserted the soldiers around you", Izan responded immediately "I left to get Marcus from his platform; I thought it would be a good idea since the walls were generally lost".
Levi asked "I see, so what do you want me to do" Izan spoke "I need you to tell me where my gear is because I'll shut the gates but I'll be wanted for escaping prison so I won't be coming back. Also give this to Mikasa when I've successfully left the wall, she'll understand". Izan handed "Levi a letter and they exchanged a nod, before Levi told Izan where his gear was. Shortly after Levi left, Izan kicked side of Hellflix's bed and said "time to go". Hellflix got off his bed and pulled a knife out of his sleeve. He picked the lock and the first step to their escape was complete. Then they opened the door slowly and saw that the guards were back on to them. Hellflix and Izan used stealth to knock them out they progressed their way to the evidence room where their gear was held. When they arrived there they were lucky to not have been detected since there was a soldier standing directly in front of them. Then they heard an alarm and ran into the evidence room.
Izan and Hellflix nodded to each other. Izan and Hellflix snuck past the guards and escaped to the gateway to the outer world. They forced the guards at the gate to open it for them. They fled through it, but just before that some guards noticed Izan and Hellflix near the gate and signaled the alarm. It was too late Izan and Hellflix had already escaped and were on the opposite side, soon to escape the tunnels on the opposite side.
When they reached the outer doorway into the wild they heard the sound of horses running and the sound of blades being drawn. Izan spoke "Marcus you need to transform if we are to live. Hellflix nodded and ran a few meters away. He thought about transforming and hit his palm with his brass knuckles. The transformation was immediate and in his titan form he reached out for Izan. Izan jumped and Hellflix put him on his shoulder before beginning to sprint toward the outer walls. Izan glanced back to see the soldiers that pursued them stop after leaving the tunnel they then turned around and went back inside.
A few days later Mikasa was in the temporary base's bunk house and was greeted by Levi who gave her the letter he promised Izan to give Mikasa. Mikasa asked "whose it from" and was answered by Levi who said "it's from Izan Bronze he left it to give you after everything settled down". She was excited to see what it said and read it to herself. What was written there went as follows "dear Mikasa, by the time you have received this you must already know that the walls have been sealed. Also you have probably been thinking about me since then and it is most likely possible that you have went on expeditions and saw flashing in the trees as if light was deflecting off armor, I will be happy to tell you if you have seen it, it means that I have successfully sealed all the gates and I still live today. On your next expedition I think you should go to these flashing lights and investigate, Sincerely Izan Bronze".
A few days later the soldiers managed to rid the areas within Wall Rose of titans. And as they were on an expedition Mikasa noticed a titan who was once walking, fall in the distance. She decided to go investigate along with Eren and Armin. When they came close enough to see what happened clearly. They noticed Izan in his full armor form stabbing the nape of the titan's neck. Mikasa quickly dismounted and ran to him. He tapped his armor once and the helmet melted away revealing his face. Izan stepped off the decaying corpse and Mikasa wrapped her arms around him. Eren yelled to him "you damned traitor… you left us to become titan food in the underground complex". Izan spoke in a low voice "if I left you guys… I wouldn't have sealed the broken gates", Eren spoke "that can't be true, how are you still here then". Izan spoke to Eren "I did it from the outside to the inside; I even killed a hundred titans while I was at it". Eren didn't want to believe it and Izan spoke again "look bro, if you don't want to believe it check for yourself. The walls were collapsed from the top by sword strikes". Armin just stood silent and Izan pushed Mikasa away before saying "Mikasa I'm sorry for cutting this short, but I've got things to do and titans to hunt… but if you ever need me just follow the sound of loud gas explosions okay". Mikasa nodded with a tear in her eye. Izan took a deep breath and sighed before wiping the tear from her face and kissing her on the cheek. Izan spoke one final time "farewell, comrades… farewell for now"; Izan then used his S.O.J.B and left toward the wooded area not far from their location.
That was the last time that Mikasa saw Izan and she thought about if she would ever see him again, but then she remembered his words "farewell for now". He was most likely watching from somewhere and probably thinking of them at times. But he never showed up, and that's how it stayed"
