So basically Hange and Levi had a one night stand after the rumbling because Levi thought she died and since she was very important to him he just needed to be with her and because of that she got pregnant but didnt tell Levi...yet...because she didnt want to stress him out so 9 months later she gave birth to you and now it was a day after you were born, today was the day she would tell Levi about you but right now she was holding you in her arms with a loving gaze
