Potential Twist...??
After watching the Adrianna whacking firsthand (thanks to the Monday evening replay)...I know we're supposed to believe that she's dead - but is it possible that the clip of her driving to California was reality...with the whacking being her daydream?? I just find it odd that she's still under contract through next season.

On a side note...I'll be amazed if she doesn't get a nomination for Best Supporting Actress. Her acting in that episode was tremendous.
