I love everything about this episode. Not least of which is that it sets up O'Brien so nicely. It is also a neat trick on the Federation's non-interference. Because they are fair and just in theory, but O'Brien, "Everyman" that he is, just can't abide by the unfairness. It sets the stage for his unique decency. Plus Tosk is just great.
But one thing, about the Dominion's control in the Gamma quadrant, was that I always wished that played into the war more. Maybe some dissenters at the prison camp where Bashier is held who were Gamma quadrant species? Maybe a hunter humiliated being captured like a Tosk? Did none of the other species in the Gamma quadrant see the opportunity to rebel? Maybe it would have been too much.
