Throughout the series, Quark was often locked in a battle of wits with station security chief Odo, who regularly foiled Quark's criminal schemes. The two eventually developed a grudging respect for each other. When Odo finally left the station to rejoin the Great Link at the end of the series, Quark came to say goodbye, and made a toast to Odo. Quark also had a firm friendship with Jadzia Dax, with whom he often played tongo. Although Quark presented himself as amoral and ruthless, he deeply cared for his friends. In "Move Along Home" when he was apparently forced to sacrifice one of four crew members (Sisko, Dax, Bashir and Kira) in a strange alien game, he refused to make a choice, begging for their lives.
