Nog returns to DS9, limping, with a cane. He turns down Captain Sisko's invitation to a party in his honor, preferring instead to go straight to his quarters.
After his leg was critically hit in "The Siege of AR-558", Nog was outfitted with a biosynthetic replacement and spent a couple of months in therapy at Starbase 235. Nog felt a lot of pain in his new leg even though the doctors couldn't detect any stimuli in the pain receptors of the leg.
Now on medical leave, Nog drives his roommate Jake crazy by listening to a recording of I'll be seeing you (sung by Vic Fontaine) over and over again for three days. When Jake can't take it anymore, he removes the data rod from the music player and Nog goes to the holosuites at Quark's, where he has Vic sing him that song in over a dozen different arrangements. Nog stays at Vic's hotel suite for the night. With reservations, Ezri Dax signs off on the idea of Nog staying there for his rehabilitation.
Vic gives Nog a cane similar to one Errol Flynn once used, to replace Nog's Starfleet issue cane. When Jake visits Vic's with his girlfriend Kesha, Jake and Nog get in an argument and Nog turns a table on Jake. Vic throws Nog out. Back at the suite, Nog apologizes to Vic.
Fretting about his finances, Vic hands Nog his ledgers. Nog finds that not only has Vic nothing to worry about, the IRS owes him a lot of money. So much, in fact, that Vic can afford to build a new casino. As Vic and Nog plan the new casino, Nog relies less and less on his cane. Ezri talks with Vic about Nog's recovery, and Vic realizes it's time for Nog to go back out into the real world. When Nog refuses to do so, Vic shuts down his own program and resists the Ferengi's attempts to restart it. Miles O'Brien explains to Nog that Vic is a different kind of hologram program. Vic shows up without the holographic environment and has a heart-to-heart talk with Nog. Nog decides to end his leave, returning to limited duty at first. As thanks for Vic's help, however, Nog convinces Quark to leave the program running all the time, effectively giving Vic a 'real' life.
