During the second appearance of the character in "Tears of the Prophets", Bashir and Quark (Armin Shimerman) run Fontaine's program in an attempt to cheer themselves up after realising that they will never have a chance with Jadzia Dax (Terry Farrell) because of her relationship with Worf (Michael Dorn). The hologram advises them to move on with their lives. In the first episode of the seventh season, "Image in the Sand", Worf is mourning the death of Jadzia. He goes to Fontaine and asks him to sing the Frank Sinatra song "All the Way". Fontaine sings the song reluctantly, and partway through, Worf begins to destroy the bar in his grief-stricken rage. At the start of "The Siege of AR-558", Fontaine auditions Rom (Max Grodénchik) as a new lounge singer. He does not get the job. Later, while the Federation troops are under siege by the Jem'Hadar, Bashir plays Fontaine's recording of "I'll Be Seeing You" over a sound system to raise morale. As a result of him losing his leg during the siege, in "", Nog (Aron Eisenberg) keeps playing that song in private upon his return to "Deep Space Nine". He goes to the holosuite to play the Fontaine program, and begins to rely on it, effectively moving into the holosuite permanently.
