Rusty has come out of the closet.
On Major Crimes Season 3 Episode 5, Rusty used a case about a girl who went against her social mores and disappointed her family as the catalyst to reveal his big secret.
Honestly, I didn't know if any of what we saw was real or fantasy until the last five minutes.
As a storytelling vehicle, I wish it had all been fantasy, with very little reality infused. While I can believe that Rusty is empathetic and could probably glean a lot of Lena Madhaven's story merely by identifying with her, he would have been unable to tell Dr. Joe all of the details he shared.
