Wangst: A couple of Savannah's siblings at one time or another... Atlanta and Marietta come to mind.
Oh, and Cordele. She shows up on Savannah's doorstep uninvited to talk about how they were neglected as kids (she's studying to be a psychologist). Not only is she angry when Savannah refuses to live in the past, but she consistently plays The Eeyore (when Savannah reminisces at a fancy dinner how they used to go berry picking, Cordele says she's hated berry picking since they found a dead cat), and complains about how Savannah spent only four hours and fifteen minutes alone with her since she came. Yes, she counted it down to the minute.
