Diane appears three times in the Cheers spin-off, Frasier. She is the dream figure from Frasier's mind in "Adventures In Paradise (Part 2)" (1994) and "Don Juan In Hell" (2001). On the other hand, Diane appears in the flesh in "The Show Where Diane Comes Back" (1996). In Los Angeles, she lost her job by accidentally setting Jane Seymour's hair on fire at the set of Dr. Quinn Medicine Woman. Moreover, she lost her friends, boyfriend, beach house, and financial supporter of her upcoming play. Therefore, she arrives to Seattle for help from Frasier. Later, during rehearsal of her play, inspired by and resemblance to her experience in Cheers, Frasier goes frantic and then talks negatively about Diane. After the rehearsal, Diane reconciles with Frasier about leaving him in Europe years ago. Finally, she decides to postpone the play and then to move back to Los Angeles.
