Interesting…so this really is someone like Eren. Then I guess it’s safe to say that unless Eren’s father is helping the other side, the transformation into an Eoten must be inherent in humans and Eren’s was just forcefully induced by his father. It also seems like whoever the culprit is, she has a lot better control over her transformation than Eren does.
But now the question is: what is the motivation? What is causing these humans to take Eoten form and take down the walls of humanity? I guess it could be that they just want humanity to live as Eotens or something…but is that all there is to it? Or maybe I’m completely off base because I misinterpreted something. Anyway, next week the fight against human form, I guess.
