They're human so yes, they can cry. They don't produce tears though. I think it would be pretty cool if instead the light of their eye lenses flickered to show that they're crying.
I was hoping it would take longer than half an hour to think of another question 😑 I was hoping it would be a day or two at least.
But anyway, taste and smell?
Is their sense of taste as sensitive as a human? Is their sense of smell as receptacle as a human? I guess I’m mostly wondering how close of a comparison various senses would be to a human.
Their senses are most likely comparable to an organic human. With one important difference. A regular human's senses begin to deteriorate with age. Exos don't have that issue.
