I think by the time appeared T’Lyn in wej Duj, they had already produced most/all of Season 3, and didn’t realize how much of a hit she would be. And then there wasn’t an opportunity to go back and add her in. I think they had just enough time/room to add her to the end of S3E10
DS9 episode “Chrysalis”. There’s a great scene where some augmented, yet socially challenged savants dress up as Starfleet officers. Patrick pretends to be an admiral. When other officers ask him what’s he’s doing, he responds with, “that’s a stupid question,” and they let him proceed with commandeering a ship, etc.
Who skips the scenes at Vic’s??
