David and Keith continue trying to iron out their problems...and Karla has a secret that isn't going to make things any better. Meanwhile, Claire takes a curious approach to photography, Ruth prepares to move ahead with Nikolai and Brenda's engagement anxiety leads her on a sexual adventure with Melissa.

While the partner of a recently deceased gay man is orchestrating an operatic tribute at Fisher & Diaz, Lisa plans an unwanted birthday party for Ruth. Meanwhile, Claire has a night to remember with Russell and two outlaw art teachers.

With Keith out of town on business, David gets taken for a ride by a hitchhiker. Meanwhile, Nate feels out of place in a bereavement group, Ruth tries to play matchmaker--to George's chagrin, Claire feels empty after a critique of her self-portraits, Brenda and her mom go back to school, and Federico gets an unexpected visitor at work.

Brenda is disturbed by Nate's reaction to her latest news; Ruth shares her feelings about George with her knitting circle; David and Keith 'propose' to Mary and meet Roger's equally unconventional family; Rico is shocked at how Vanessa and the boys are doing; frustrated, George shares a beer and a song with Billy; and Nate comes home to an unpleasant surprise.
