1. If you see dust but nothing else, then there's a chance he just walked by.

I remember when I shaved my head the first time, using grease to cut back my hair. Trying to be tough by not coughing when dust got caught in my throat. Letting the precious water trickle down my skin, when I missed my mouth, because I thought that Riddick wouldn't care about lost moisture, he'd be gone before he had to worry.

I remember his smirk when I asked him what I had to do to get eyes like his, and he fed me that bullshit story. I believed him, until years later I went looking for my own pair.
