The first act of the second episode of season 2 of DS9 is possibly the best scene in all of Star Trek

I'm rewatching it now, it's so well written that it almost stands out from the rest of the episode. It comes off like something from David Mamet or The West Wing. It's not Far Beyond The Stars or In The Pale Moonlight, the stakes of the episode are too low. But the material it gave all the actors to work with, the incredibly realistic way it weaves together different conversations going on between a large group, that the (really really good) acting abilities of the cast just get pushed over the top. It's all in one room, no effects, no cost except for the appearance of Bareil, but it's riveting, you can't stop paying attention. It's kind of a master class in writing. And it's buried after the opening credits in the second episode of season 2.
