Yes, that's the one in which Nog still hasn't completely psycho-emotionally recovered from what happened to his leg against the Jem'Hadar and walks around with a cane at the beginning of the episode for a while. It's also the one in which Vic is telling him he has to do his taxes otherwise "Uncle Sam's going to come down on me like a ton of bricks" and Nog sympathetically replies "Sounds like my uncle."
