This season of Frasier finds the Crane household in a variety of turning points. Niles' (David Hyde Pierce) long-separated wife, Maris, finally serves him with divorce papers, while Frasier (Kelsey Grammer) finds himself trying to build a better relationship with Frederick (Trevor Einhorn), his son. Martin (John Mahoney) starts his first serious relationship in years, though his sons hardly approve of his choice in women, and Roz (Peri Gilpin) tries to broaden her horizons as well. Though Daphne (Jane Leeves) is still oblivious to Niles' crush on her, she still manages to build a closer relationship with him than they had in the past.
