Attack on Titan: Shingeki no Kyojin

He didn't really look like a noble's son who got an officer's rank as a birthright.

The social setting would suggest such, but the way it was spoken was as if someone asked me "I don't get it, why would you eat dirt?"

The confusion and your post still doesn't really explain to me if people don't eat potatoes because they're expensive, or if people don't eat potatoes because they're pig food. It was in the kitchen, so clearly someone eats them.. but still. Doesn't help.

You lost me. I thought you were joking in your earlier post. He asked her why she's eating a potato because he was actually as shocked as anybody else there, if not more so, that somebody would dare to start to eat during his gentle greeting to the troops. However, I don't see during that scene anything to suggest potatoes would be considered of low value. In fact, since lots of people were dying of hunger after the outer wall was lost, potato would be regarded as an ultimate food, not any less so by the military. Wars can't be fought on an empty stomach and potato is very convenient in many ways.

But she's not the only one. Mikasa herself is pretty obviously damaged in the head. Armin correctly identified Eren's thoughts, that he no longer has to be dependent on Mikasa for help. Mikasa immediately refuted that and said what it was really about was that he was relieved the two of them can continue to stay together. Creepy...

Considering the world they are living in, it would be creepier if there weren't lots and lots of damaged people around.
