[For a moment Armin's eyes widen, then his brows furrow. The question of how that is possible is on the tip of his tongue, but he swallows it. Something about her words make him think she doesn't know exactly how it works either.]

So... so if we manage to get back home, it'll be the same as when we left?

[Honestly, if that is true, that is immensely reassuring. Puzzling too, because Armin cannot see how it works, but at least that way he doesn't have to worry about Eren and Mikasa. Nor about the theory he has about Annie that he didn't think to share with anyone yet.]

Have people gone home before? And returned?

[They must have, right? How else could anyone know this?]
