#22: 3x10: Blink

The Lonely Assassins they used to be called. No one quite knows 
where they came from but they're as old as the universe or very 
nearly. And they have survived this long because they have the 
most perfect defense system ever evolved. They are quantum locked.
They don't exist when they are being observed, the moment they 
are seen by any other living creature they freeze into rock. No 
choice, it's a fact in their biology. In the sight of any living 
thing, they literally turn into stone. And you can't kill a stone.
Of course, a stone can't kill you either. But then you turn your 
head away. Then you blink, and oh yes it can.
