This is a double-length episode and like many of these lengthy episodes and season openers, LOTS of stuff is happening! The biggest change is Worf becoming a regular on "Star Trek: Deep Space 9" but Captain Sisko is now bald and once again pretty much ignores his commanding officers' orders. This isn't new but is at least the third time Sisko gets away with this!
The show begins with Worf begin transferred, at least temporarily, to DS9 because some problems are now brewing with the Klingons around the wormhole. They have arrived en masse on the station and they are in a VERY argumentative mood. Why all the posturing and anger on the part of the Klingons? What is their goal? And how does this all fit into the wicked Founders' plans?
This show is decent because LOTS happens and there is lots of action. On the other hand, the show is NOT especially logical and Sisko's intervention in the Cardassian-Klingon war makes little sense--nor does his risking everything to save Dukat and the Cardassian council. Sitting back and just letting things take their course would have made a lot more sense. Plus, how is it that Sisko wasn't taken up on charges for his latest insubordination?!
By the way, in a tiny role aboard the Defiant you see Patricia Tallman--the same lady who would begin playing Lyta the telepath on "Babylon 5"this same year. Several other Trek actors would also appear on "Babylon 5" and vice-versa over the years, such as Andreas Katsulas playing a recurring role as a Cardassian on "Star Trek: The Next Generation" as well as a regular role on "Babylon 5". So, for fans of both franchises, this is a particularly noteworthy episode.
