That's a nice "move" caveman, I'm going to tell my Warriors to steal that.
If it was logically plausible, such as in the woods, or in a dark room or full of rubble (and bodies) AND my the thief asked, I'd make them do a "sneak" check (which ever made the most sense) if they succeeded (DC = 3d6+HD), she can get her back-stab bonus & auto-crit. She was awesome, but she's dead now.
