Blueberry

Blueberry (played by Tara Buck) was a woman, presumably a prostitute, that met Donald Pfaster at a truck stop in Illinois and rode off with him after nearly killing Robert Gailen Orison. Blueberry got more than she bargained for with Pfaster and was found brutally murdered in a bathtub. (TXF: "Orison")

Her name is a reference to the blue nailpolish she wears.
