King has this perpetual look of sadness when I see him. Between being the last of his people, constantly tortured, and having to protect his identity from everyone, he seems far more tragic a character. It'd be real unfortunate if this is the last we see of him in the arc. He's become far more interesting in just this chapter alone.
There has to be some kind of connection between the Shandians and the Lunarians. King looks very similar to Wyper.
