Jo is not a foolish woman. She could not stay alive down here so long if she did not have the sense to see a situation for what it is instead of what it appears to be. A fool might look at this scrappy Dog clutching a knife with a fighter's fist and circling with a ready stance and see the only threat there in front of them. But a fool like that becomes a dead fool fast. Jo knows this mutt slut well. She is not the running type. Jo is wary of that knife, but she's far more wary of whatever has chased this prideful mongrel down into the rat maze. Jo doesn't want to take her eyes off of the Hellhound, but she takes a step backwards and glances quickly over her shoulder, as if to check that whatever the other woman is running from isn't right behind them. She cuts her eyes back to the Dog bitch, and though she is pacing away from her movements, keeping a careful distance between them, she doesn't raise her weapon and she doesn't strike.
