Dina was sitting in a small room. Documents were piling up on a small counter in the corner. On the walls, the maps were hanging with little trails recently put on them. A drawing board was standing by the door.

Erwin came to the room and sat over his counter. Dina looked at the closing door and saw that there was a soldier standing just outside.

"Am I under house arrest?" She asked Erwin.

"This is just a temporary predicament in order to protect whatever information you have" Erwin replied, "I assume that you were serious about what you said."

"Yes" Dina replied nodding.

"Good" Erwin said as he sat down and cleared his desk "now please, tell me what you know."

Dina pondered for a while.

"First of all," she started "You must not tell anybody about what I say to you tonight."

"You have my word" Erwin promised.

She took another deep breath.

"I won't tell you everything I know just yet" she said, "I will do that in the right time."

"Even a small piece of information is valuable" Erwin replied, "we are used to march into the unknown, however any useful detail could save many lives."

They were clear. Dina was sure of her decision.

"The enemy has infiltrated our ranks" she said, "they are an organized group, and they have a clear plan."

Erwin was looking at her attentively.

"That's exactly what I think too" he said, "what is this group you are talking about?"

"They are a group of humans who possess the ability of transforming into titans" Dina exclaimed "the armoured titan and the colossal titan are ones of them."

Erwin smiled.

"I figured as much" he said, "it was just an assumption though, so it's nice someone else has a similar opinion."

"There is at least one more of them within the walls" Dina continued "outside the walls, there could be more. Three are here, and there are three more outside."

Upon hearing that Erwin stood up and looked her in the eyes eagerly.

"So, there are people outside the walls?!"

Dina startled aback when he did that. He was looking at her so intensely that she blushed and looked down. Erwin saw that and he sat down embarrassed.

"Sorry" he said, "I got excited."

"Alright" she replied, "I can't tell you anything about it yet."

When Erwin heard that he somewhat looked dejected. Dina was really curious about his outburst, so she asked:

"Why were you so fired up when I said that?"

He looked down and closed his eyes.

"My father was a teacher" Erwin started "he taught children in the region where I was raised, so I learned in his classroom. One day during his class something life changing happened. That day, we learned history about how humanity ended up cornered inside of these walls."

"There was not a single historical record left from before the day humanity escaped to the safety of the walls. The majority of humanity perished, and we were left with only a tiny bit of land, but we managed to put an end to our constant conflict."

"He said that we had gained an ideal world here inside the walls. That's when a question came to my mind. My father deflected my question and finished the class as always. But after we returned home, he answered me. He said the history texts the royal government distributed were full of mysteries and contradictions."

"Even if there were no documents left about those times… The first generation that entered the walls should have been able to teach history to their children. On the contrary, it would have been next to impossible to keep completely quiet and say nothing about the outside world to the next generation."

"What my father said next… was astonishing, even to a child like myself. But I wasn't smart enough to figure out why he hadn't talked about it during class. I told the kids in town about what he had said and the next day the military police asked me about it."

Erwin took a pause.

"My father didn't come home that day. He died in an accident in a faraway town. Because of my stupidity, the crown killed my father."

He closed his eyes.

"His theory was that over a 100 years ago, the people of the walls had their memories altered, so the king could control them better."

Dina listened to his story in silence. She felt really sorry for Erwin.

"I'm sorry to hear that" she said.

"Don't mind it. I shouldn't bore you with the story of my life." He replied with a weak smile.

Dina thought for a moment.

"What question did you ask in that class?" She asked him.

Erwin looked her in the eyes.

"How could we possibly know for sure, that no people live beyond these walls?" He spoke.

Dina was pondering on whether she should disclose a little more information to him than she originally planned.

'He deserves to know' she thought as she made up her mind.

"Your father was right" as she said that Erwin's eyes went wide "the king altered the memories of his people."

"H-How could you know that for sure?" He asked disbelievingly.

Dina took yet another deep breath.

"I am from the royal family" she explained "although I'm a distant relative, I can assure you that the theory your father had, was right."

Erwin stood up from his seat again. He walked over to her. Standing before him, Dina felt vulnerable, yet something about him was reassuring. She hadn't felt like this in a long, long time. But she didn't want to think about it just yet. She pushed the thought aside and looked him in the eyes.

"I can't tell you anything else" Dina said "however, I promise that when the time comes, I'll tell you everything."

Erwin nodded at that.

"I have no way to confirm what you're saying" he said "but I believe you. I can wait a little longer if it means that I get to know the truth."

Dina was glad she trusted Erwin. She finally had someone who had her back. She wasn't alone anymore.

"Nonetheless" Erwin continued "even if you made all of that up, what you revealed about the enemy, is very logical. I'd like you to work with me on something important."

"Y-you want my help?" She asked.

"I believe your insight may prove useful in my plan for the next expedition" Erwin said with a smile "also, by keeping you close I'll be able to find out if you aren't the enemy yourself."

It was necessary for the time being. After all Erwin didn't know anything about her, other than what she told him. If they were to cooperate, she would have to accept that he had the right to be a little suspicious.

"That's fine by me" she said confidently "I'm looking forward to working with you."
