A desert, a crossroads, a car that won't start, roadkill. Sounds about right for the characters of Six Feet Under. At Fisher & Diaz, lives are in flux. Nate is struggling to reaffirm his relationship with Brenda while raising his daughter, even as David and Keith long for children of their own. Ruth tries to cope with her mentally fragile husband George, Claire seeks to broaden her horizons, and Federico strives to fill the void left by Vanessa.
