Pushed to our limit, any one of us could kill somebody. You don't know precisely what your own cataclysmic pressure point might be. Angel thinks hers relates to a knife. In truth, it relates to a fall. Most people think of the Rocky Mountain states as the last safe place.

Angel has, like most people, four ethnicities if you trace back far enough. And, as in everybody else's case, none of them has anything to do with why her life doesn't work. It lets others know how well they are doing. At the same time, we learn a lot through our entertainment. We learn how to live more fully and what to turn loose of.
