SURVEY CORPS
Erwin's office
Levi, Hange, and Erwin meeting.
"I see, you wanted to know the truth about Titan." Levi said.
"Everyone was confused that Titan saved humanity for first time." Hange said and thought.
"If we can find Titan then we can use that?" Hange rubbing at her hair. Erwin sit on table and looked down.
"I don't know where Titan from outside... people still clueless about history." Erwin talked and a hand on his head. "I wanted to know the truth about the world." Erwin replied.
"Commander Erwin, 104th Cadet Corps scared to join me because they fear of titans." Levi muttered.
"I can't believe. Krista Lenz have Eren's key for basement... if we can reach Eren's basement about the truth. That my father was correct." Erwin talked.
"I don't know where is Eren still missing." Hange replied and think Eren.
"If I find Eren and He can tell everything about the truth." Levi muttered.
"I wanted to meet Eren, I wanted to him tell me everything... I wanted the truth." Erwin replied.
"Tomorrow, 104th Cadet Corps show up and who wanted to join Survey Corps. What do you have idea? Commander Erwin?" Hange asked Erwin.
Erwin stand up. "I will speak them about Titan and Survey Corps."
TOMORROW AT NIGHT
104th Cadet Corps stand for who wanted to join Survey Corps.
"I am Erwin Smith, Commander of the Survey Corps.... Today, you will choose a military branch. Put bluntly, I'm here to persuade you to join the Survey Corps." He sighed. "During the Titan attack, you learned how terrifying they can be. And how limited your own power is. However... this battle brought humanity closer to victory than it's ever been."
"The who Titan saved humanity and enemy of titans. Titan is friend of humanity, Titan own risk to saved humanity from titans." Erwin said and looked away.
"With his help, not only did we stop the Titans' advance, but we have a way to discover their true nature." Everyone was shock.
"Eren's necklace was Krista have kept... He knew everything about the truth from his father."
Reiner, Bertholdt, and Annie eyes widened. "Eren, don't tell me you..." Reiner said in shock.
"Eren know about titans, world, and most secrets. They believe he still alive we can find him. We still don't know where is he." Erwin explained.
"Key for his home's basement have secrets in Shiganshina... if we can reach that basement, we will find a clue that will end this century of Titan rule. If we learn what they are, we can end this!" Erwin explained.
"We will find that Titan and used him to kill all titans."
"We'll have to take the long way around, from Kaeanes to the east. The four years we spent laying a route for a large army have gone to waste." Erwin continue speak. "In those four years, more than sixty percent of the Survey Corps lost their lives. Sixty percent in four years... an insane figure. Any trainees who join will participate in our excursion beyond the walls, in a month. We expect thirty percent won't return. I'm four years, most will be dead. But those who survive will become superior soldiers with a high survival rate." Erwin closed his eyes then open. "Knowing these discouraging facts, any still wiling to risk their lives, remain here. Ask yourself..." Erwin speak.
"Are you willing to offer your beating heart for humanity?" Erwin yelled. Everyone gasped and see him. "This is all. Anyone who wishes to join another branch is dismissed." Erwin final speak.

"Reiner, do you think you still join Survey Corps?" Annie asked him.

"I have good idea, you and Bertholdt will join Survey Corps... I will join Military Police I can destroy the gate again." Reiner make decisions.
