Jimmy faces a bar investigation, and Kim and Jimmy's strategy of exposing Chuck's electromagnetic hypersensitivity as a psychosomatic illness discredits his testimony. Jimmy is suspended from practicing law for a year, but not disbarred. Chuck's paranoid performance as a witness degrades his professional reputation, and HHM loses standing in Albuquerque's legal community. While Jimmy tries various ways to generate income so Kim and he can keep their shared office, Kim takes on a second client. Rushing to a meeting after little sleep, she crashes her car and breaks her arm. To save money, Kim and Jimmy break the lease on their office and Kim practices from home, while Jimmy helps her with day-to-day activities because her arm is in a cast during her recovery. Howard forces Chuck out of HHM, and an increasingly erratic Chuck sets a fire in his home by knocking over a camping lantern, but makes no attempt to leave. Following Chuck's suicide, Kim tries without success to break Jimmy out of his despondent mood. Howard tells Jimmy and Kim he thinks that his decision to force Chuck's retirement from HHM after their malpractice insurance rates rose led to Chuck's death. Jimmy conceals his role in causing the rate increase, allows Howard to shoulder the blame, and regains his usual happy-go-lucky demeanor. Unaware of Jimmy's actions, Kim later berates Howard for mistreating Jimmy. Kim works on Mesa Verde's rapid regional expansion, but is increasingly bored with banking law, so she begins taking "pro bono" criminal defense cases, which she finds more interesting and satisfying. After she is reprimanded by Paige for putting her "pro bono" work ahead of Mesa Verde's, Kim persuades Schweikart & Cokely to hire her as a partner to manage a new banking division, which enables her to handle the Mesa Verde work while continuing to devote time and effort to criminal defense cases. With her career becoming more successful, she becomes more distant from Jimmy, who works a boring job as a cellular phone store manager while he serves out the suspension of his law license. By 2004, Jimmy has a lucrative side business reselling prepaid cellular phones on the street under the alias Saul Goodman, and hires Huell Babineaux as his bodyguard. Huell has a run-in with a police officer, who arrests him, and Jimmy convinces Kim to defend Huell to keep him from receiving a prison sentence. Finding it impossible to convince the prosecuting attorney to enter into a plea bargain, Kim and Jimmy run a con to fake a show of support for Huell in his hometown.
