At the welcome party for the visiting scientists, Dax and Kahn warm to one another's company once more. Afterward, they begin to socialize as they work together on Kahn's wormhole experiment aboard USS "Defiant". They agree to have dinner, but to also bring Bashir along as a chaperone. At dinner, Bashir is effectively ignored by the two Trills as they reminisce about their past hosts. Later, back on the "Defiant", Kahn successfully creates an artificial wormhole and Dax hugs her in celebration. Kahn's brother Bejal (Tim Ryan), who is on the science team, speaks to her separately and highlights his concerns regarding her contact with Dax. Despite this, Kahn goes to Dax's quarters and a discussion between the two leads to a kiss; Kahn leaves before it goes any further.
