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.

Ruth goes on a fossil hunt with George, and digs up Sarah and Bettina. Claire focuses her talents on Edie; Federico tries to unload on Sophia; Vanessa does some part-time detective work; Keith goes 'out' to a bar with his co-workers; David drowns his stress; Nate dares Brenda to be honest with Joe, and receives some relationship advice himself.

Ruth is giddy about going to a tantric workshop with George, who retreats to the family's emergency shelter. Meanwhile, David's last bite at a sushi restaurant threatens to cost him--and Keith--a lot more than the bill; Nate drops a bomb on Barb, which sparks a counterattack; Claire fights Russell over credit for her latest photos; Margaret's hospital stay helps Brenda and Billy begin to heal their rift; and Vanessa shows she can beat Federico at his own game.
