[ Eren shifts on his feet as he watches her, more agreeable than most at first, and then... puts on a show of being fed up with it. It's a bit contradictory, or maybe she just realizes battling for their lives is more important than personal feelings. ("Chosen shit" gets another raised eyebrow, but he wouldn't guess getting knocked off her pedestal as princess and being forced into a life of fighting dragons is the reason behind her words—far from it, really, so he doesn't think much of questioning it.)

But he does give something of a wry huff, because he doesn't quite share those frustrations. Eren's purpose is far too focused on these sorts of matters to ever think about complaining about it. ]

Griping about it isn't gonna get you anywhere. You have the chance to save your world. That's not something to get angry about.
