So now maybe Levi’s got a rock collection, but it’s perfectly reasonable, you know.
For one, they’re all from Eren. Eren in his titan form, because for some reason the boy has yet to give him one in his human form. Still, Levi doesn’t mind. Maybe there’s something instinctual in titans—giving away pretty rocks as a form of affection. Whatever. Hanji would go wild over that theory.
