When Gowron meets K'Ehleyr in the observation lounge, the camera points toward the ceiling. The top of the wall/set is briefly visible in the upper right corner of the screen, showing that there is no ceiling.
In scenes on the Enterprise with Gowron and Duras, armed Enterprise security are present. Yet when Gowron goes to find K'Ehleyr, no security guards are with him.
Duras flubs the Klingon word Ha'DIbaH (animal). He transposes two syllables and says "ha'bidah" instead. (Worf made the same error in Sins of the Father (1990).)
