IIRC, Rohm had probably the world's WORST exit line from any TV show ever..I think there was a contract dispute, she wanted more $$$..and they wouldn't give it to her, so they rewrote/modified the last episode of the season to get rid of her character. She was dismissed from the DA's officer, and in the last scene, before the fade, she's sitting in Branch's office...and she asks him, somewhat plaintively.."Is this because I'm a lesbian?"
Fearless prediction...Look for that scene to make a big splash on the campaing trail
