Odo is rushed to the Infirmary when he suddenly collapses. After a thorough examination, Bashir determines that Odo is losing the ability to maintain his solid form, but is unclear as to why. Despite his protests, Bashir gives the patient strict orders to remain under observation since movement could bring on another attack. Odo, unable to keep from his investigations, ventures out of the Infirmary and promptly collapses into a puddle of goo. His condition worsening, Odo realizes that the only place he can find help is with his people -- the Founders, rulers of the Dominion.
