I may be mistaken, but I seem to remember dialog in "Siege" where Dr. Bashir says that Nog will permanently lose his leg due to complications that could have been prevented in a Starbase infirmary. I thought this was extremely bold; they were going to show the consequences of battle, and there wasn't going to be a big reset button to make it all okay. Nog would have to live with it for the rest of his life. Cut to "Paper Moon." Nog enters with a cane and a limp. So far, so good. They obviously carried through with the idea, and Nog now has some kind of prosthetic device. But, it turns out he has a perfect, fully-functional replacement limb. Other than the psychological reaction causing him to limp and feel pain, no one would know he had lost a leg. I just picked up the DS9 Companion, and this issue isn't addressed (from what I've read so far). Was this the plan all along, or did the word come from on high that Nog would not be allowed to suffer a permanent disability? I've read of other instances where the intended result of a storyline was undercut by squeamishness from the powers that be, and this feels like a case-in-point. Don't get me wrong--I like the story as aired. It remains an interesting study of Nog and the cost of war. But, I wonder if it was meant to have an even greater impact. It could have even been the catalyst for the theme of living with a disability. As it is, it was no longer an issue with Nog after the episode was done (not that there was much time, with the show winding down).
