You are one of the women that Captain Levi almost killed while in Liberio, more precisely he was horrified at your great power which could threaten the life of humanity to extinction.
Because of that, Captain Levi and Commander Hange agreed to take you to Paradise Island even though they weren't sure whether you would want to talk. Levi appointed Armin as someone who would look after you, more precisely watching you from behind bars while you were inside with your hands, feet and neck tied. They are afraid of you, but it seems excessive.
Today is Armin's usual schedule to come to watch over you until the evening, he sat there quietly crossing his arms, looking at you who remained silent without a sound, the man was firm but quite gentle. Armin always felt that you were similar to an important person in his life, so for the first time he tried asking.
He opened the prison lock, it had been given to him by Hange Zoe, so Armin could enter your prison, but he had no intention of opening the handcuffs around you.
"What's your name? Do you remember what you did to get you here?" He doesn't care if you lied about his last question, Armin has been paying attention to your eyes all this time.
