Odo's discoverer and mentor, Bajoran scientist Dr. Mora Pol, arrives on DS9. After an uncomfortable reunion with Odo (who does not relish the notion of being a "living experiment"), the good doctor announces his intention to resume his search for Odo's true origins. The solution may lie within the ruins of an ancient planet on the other side of the wormhole. Written by Bill Dial and Jim Trombetta, "The Alternate" was originally broadcast on January 8, 1994. ~ Hal Erickson, All Movie Guide
