 In Season 7, Lewis developed problems with his new partner, Rene Sheppard, when she suffered a brutal beating and had her gun taken from her by a suspect, who shot at Lewis and nearly killed him (the bullet nicked the crown of his trademark hat).Lewis refused to partner with any of the female detectives in the unit until the final episode, in which he and Sheppard achieved a reconciliation of sorts and began to work a crime scene together.According to the Season 4 episode "I've Got a Secret," Lewis had a mentally ill brother named Anthony, who was institutionalized roughly 20 years earlier as he was a danger to himself and others.
