Simone Hundin is a dog breeder whose husband was murdered in "Bitches". During the investigation, she and Emerson became romantically interested in one another, but nothing became of it. Later on, during an investigation in "Dim Sum, Lose Some", the two of them run into each other and become involved. However, Emerson is frightened by the degree of control she has over him, and tries to avoid her. Simone gets angry, and tells him off (and indirectly solves the case). Impressed on how she had opened up, Emerson apologized to Simone, and the two of them got back together. She appeared again in "Water and Power".
