Mrs. Turpin is Hoyt's mother from True Blood. I couldn't help but picture the character in the story the same as the character in the show, but the funny thing is that I don't think this is something new from having watched the show. I think Hoyt's mother is the way I've always imagined this character. I think I've watched the show and wondered where I'd seen that actress before and now I think I might have never seen her, but rather found her familiar because she is the precise embodiment of that particular archetypical woman that Mrs. Turpin is the perfect literary description of.
Oddly enough, even though she isn't fat or ugly, Sooki is always making the expression ("…snapped her teeth together. Her lower lip turned downwards and inside out, revealing the pale pink inside of her mouth.") that the fat ugly girl keeps making at Ms. Turpin in the doctor's office before attacking her.
