DS9 s2e21 “The Maquis, Part II”

The second part of this Maquis de Sade-centric two-parter, one of the few Treks to follow the possible Best of Both Worlds/Godfather II template of 2 being better than 1. To Andy's shock, Odo show the Mr. Fantastic powers he always assumed he was hiding, and Dukat starts to live up to his (future) legend.
