In the first episode of a two-part story, the never-seen but omnipresent Maris comes back into the life of her ex-husband Niles (David Hyde Pierce) -- but only to get some free advice on how to handle her current lover, a libidinous Latino with a violent temper. The "fun" really begins when Niles resorts to subterfuge to prevent Maris from confronting the pregnant Daphne (Jane Leeves), who has been experiencing some rather spectacular mood swings. In the end, it is poor Frasier (Kelsey Grammer), already skittish about returning to private practice, who tries to come to Niles and Maris' rescue -- and nearly gets killed in the process. ~ Hal Erickson, Rovi
