In the Special Features, Hidden File 01 on the DS9 Season 4 DVD, Alexander Siddig elaborates on why he loves this episode so much; “I loved that show, I mean I loved doing it, and Rene directed it, he was great at directing that show. I really enjoyed the fact that there’s this doctor that turns up on this planet and he is so arrogant and full of himself that he thinks he can cure the planet of all their diseases, and probably get whatever the equivalent of the Nobel Prize is. And he fails, he kills a bunch of people, a whole bunch of people die because he screwed up. That doesn’t happen on TV. The good guys don’t screw up. And I love the fact that it all went horribly wrong and he had to, you know, go back to the drawing board and figure out where he went wrong. ‘Maybe it’s because I was terribly arrogant, maybe it’s because I put my own interests above those of my patients’. That’s a great lesson for any doctor.”
