The Search, Part II

On the rogue planet, Odo is welcomed by the shapeshifters, who explain that he was sent out as an infant to explore and then return. They treat Kira coldly as a solid. Meanwhile Sisko and Bashir are rescued by O'Brien and Dax and return to the station, where the Federation is negotiating a treaty with Borath, a Dominion representative. The Romulans are shut out, Admiral Nechayev dismisses Sisko's concerns, and after Jem'Hadar kill T'Rul Sisko leads a desperate mission with Garak, Dax, Bashir and O'Brien to collapse the wormhole. On the planet, Kira finds a locked door that hides Jem'Hadar. The truth emerges: the station events were a simulation run by Borath to test how far the Federation would bend, and Odo's people are the Founders themselves. Appalled, Odo demands his friends' release and leaves with them.
