ROMANTIC ENTANGLEMENTS ABOUND IN ONE-HOUR SEASON FINALE -- Even though Frasier (Kelsey Grammer) is happily involved with girlfriend Faye Moskowitz (guest star Amy Brenneman, 'NYPD Blue'), he jeopardizes the relationship when he absent-mindedly calls her 'Cassandra' -- the name of an ex-lover (guest star Virginia Madsen, 'Candyman') he secretly dated while courting Faye. Meanwhile, Frasier gets freaked out when he realizes where Niles (David Hyde Pierce) is looking for love; Daphne (Jane Leeves) is panic-stricken when she loses something valuable from her boyfriend (guest star Saul Rubinek); and Roz (Peri Gilpin) is mortified in the wake of her passionate, yet temporary, fling with a fellow employee.
