They all had a life before this. It can be seen in the other trainees' eyes, heard in their mess hall discussions, and observed through their actions. Sasha talks too properly and stuffs her face with food. Mikasa, Eren, and Armin are inseparable. Marco has hope.
And Ymir... Well, from what she's gathered, Ymir is Ymir.
Ymir is smart. She knows something, though she can't be sure what. Her name, maybe. Perhaps her past.
Or maybe she just knows that Krista, Historia (as if any name actually matters), is just a liar. A nobody.
And maybe it's better that way.
