In the season finale, it was revealed that Saul once spent a romantic weekend in Key West with another man, an old friend named Milo (Michael Nouri) who reappears at Kitty and Robert's engagement party after an absence of 20 years.

Early in the season, Saul acknowledged to his sister Nora that many years ago he was in love with a man.

Another important clue concerning Saul's sexual orientation turned up in the episode with Kitty and Robert's wedding.

Saul finally comes out to his openly gay nephew, Kevin Walker, after getting arrested for drunk driving.

During the season finale, Saul becomes irate at the fact Kevin and Scotty take HIV testing so lightly, and his annoyance is concern to the young couple.

Having never been tested and nervous after discovering a former lover is positive, Saul secretly goes to a local hospital alone to learn that people can live with HIV/AIDS asymptomatically.

During the final scene, the Walkers are involved in an enormous car accident in which almost every member of the family is injured.
