After Garak tries to set up a date for Chalan Aroya, the owner of the Celestial Café, with Odo, the constable is suddenly in severe pain. He has great trouble to hold his shape. Bashir notices his mass and density are in a state of fluctuation. When the fluctuation increases, he gets an attack. While Bashir is optimistic at first, Odo's condition deteriorates. His molecular structure is destabilizing at an alarming rate and the doctor thinks he only has two weeks before he loses his ability to stay solid. Odo and Bashir both know there's only option: going to the Founders. When Garak hears of the planned trip, he requests to come along. He wants to meet with the Founders to inquire about possible survivors of the failed attack on the Founders' home world by the Tal'Shiar and the Obsidian Order.
