Jenny's dog is named Sounder, after the dog she adopted and had put down to get revenge on the book critic. Sounder itself is the name of a famous movie dog from the 1970's film of that title.
For the second time of the series, a 1970's blaxploitation (the genre Pam Grier became famous) song by Isaac Hayes, this one called 'Drinking', plays in the background of a scene (where Shane and Paige talk to Paige's son).
Directed by series creator and producer Ilene Chaiken. On many shows, in many cases, the creator of that show will direct either the first or last episode of each season while guest directors fill in the other episodes.
