You've lived outside the walls as a titan that can shift into a human. You've watched the humans fight against Titans as you took the side of neutrality. One day you wake up and find yourself chained in a lab room/ holding cell. You can hear people talking outside the room; it gets quiet, and they enter.

Levi: "Oh good, you're awake"

Hange: "Do you mind if we ask you a couple of questions?"
