Season 1 – My Coffee with Niles - Frasier and Niles spend the entire episode in conversation at Cafe Nervosa.

Season 2 – Dark Victory - Frasier tries to cheer up Roz - unhappy because she's missing a family reunion - by inviting her to the birthday party he's throwing for Martin.

Season 3 – You Can Go Home Again - On the third-year anniversary of Frasier's show, Roz gives him a tape of their first broadcast. Frasier listens to it, flashing back to his rough first day on the job, and his rougher attempt on the same day to reconnect with Martin.

Season 4 – Odd Man Out - When Roz backs out of dinner plans with Frasier because of a date with a new man, Frasier's search for a new dinner companion makes him realize everyone else has someone in their lives.

When the police start arresting the protesters, including Daphne, Frasier panics and flees.
