Prodigal Daughter

Sisko is furious when he learns O'Brien has vanished while on a secret trip to New Sydney, where he was searching for the widow of a criminal named Bilby, whom he befriended while undercover. Because Ezri's family owns a mining operation in the system, Sisko asks her to help find O'Brien. Ezri returns home, where she's reunited with her domineering mother, Yanas Tigan - a shrewd business woman - and her brothers Norvo and Janel, who work for the business.
