Billy Gatwood is a client of Kim Wexler.
During a meeting over dinner with Kim, Kevin Wachtell reveals he has a friend in Texas, Billy, who needs legal help and wants her to take him on as a client. Though she is initially reluctant, Kim eventually agreed to study the matter. ("Slip")
Kim and Billy meet at a remote oil field. Billy fills in Kim about his tax issues, stemming from the fact that his oil field crosses the New Mexico-Texas border. Kim promises to propose a solution to Gatwood's tax problems within two weeks. While driving to her meeting with Gatwood, Kim falls asleep at the wheel and is badly injured when she crashes her car on the highway into a rock. Kim stumbles out of the wreck as legal papers litter the ground around her. ("Fall")
While Billy is sympathetic to Kim's injuries and even sends her steaks, Kim decides to end her work for him, recognizing that she has taken on too much work. Instead, Kim refers Billy to another law firm, Schweikart and Cokely, through Francesca Liddy. ("Lantern")
