...but I think there's a Cylon working at our local gas station.

One of those skin jobs, you know, not the big shiney kind.

Anonymously good-looking, blue eyes set just a little too wide apart, hair combed into a perfectly orderly non-style.

If he had no emotions at all, I wouldn't suspect him so much.  But he DOES have emotions.  He emits this sort of constant wave of low-grade background irritation, as if he has a pretense to keep up, but he's just waiting for the right moment to fulfill his evil mission.

Every social interaction is spare, cold, minimalist and completely devoid of any kind of human content.

A Cylon, I tell you.
