( ) The first few weeks of their marriage were not all clear sailing , however . Shortly after their wedding , Yates destroyed some of Sisko ' s home - grown bell pepper s in a failed attempt to cheer him up by cooking for him . Sisko attempted to keep Yates and her freighter out of the escalating Dominion War by having the Bajoran Freight and Shipping Authority take her off the active list , much to her annoyance ; he later relented . ( ) Later in 2375 , Yates discovered that she and her husband were going to have a baby . The pregnancy was unplanned , and Sisko surmised that his last contraception injection must have expired without him returning to the infirmary for another . Yates worried that something might happen to the baby following the Prophet s ' earlier warning to Sisko that marrying Kasidy would bring him sorrow . Sisko reassured his wife that nothing would happen to their baby , giving her his word as the Emissary . ( ) During a battle with the Pah - wraith - possessed Dukat in the Bajoran Fire Caves , Sisko sacrificed his life to defeat the evil Kosst Amojan and joined the Prophets in the Celestial Temple , leaving Yates and their unborn child behind .
