With a title that's Latin for, "In the presence of arms, the laws grow silent", this Bashir spy episode is a sequel of sorts to season six's "Inquisition", bringing back special guest star William Sadler as Sloan. In a way, it's vintage Ron Moore, with a storyline that's meticulously laid out and sci fi that's made understandable and relatable. In another way, it feels like Chris Carter's X Files, insinuating a lot going on offstage and playing up the paranoia. Either way, it feels like we're in the hands of a good storyteller who knows what's he's doing.
Like Thompson and Weddle's "Inquisition", Moore is sure to give Sadler a meaty part, finding a way for Sloan to accompany Bashir on the mission. He also uses Barry Jenner well as Admiral Ross, giving him his first one on one scenes with Alexander Fadil. Meanwhile, Adrienne Barbeau replaces Megan Cole as Romulan Senator Cretak, redefining the part in a more sympathetic light. With new characters introduced (most notably, Romulan Senator Koval, generically played by John Fleck) and much of the episode taking place on Romulus, there's always a sense of tension in the air, with the multitude of characters scheming behind the scenes leaving Bashir unsure whom to trust. As the plot spirals out of control and gets really crazy, it's tempting to believe it's all another elaborate mindgame by Section 31, but to the episode's credit, it doesn't take this easy way out and delivers a satisfying conclusion instead.
Supervising Producer David Livingston, directing his last of seventeen DS9 episodes, does a great job of fleshing it all out, even borrowing Voyager's sets as a stand-in for her sister ship, the Bellerophon, showing off the advantage to having a sister show.
As with "Inquisition", the end result proves entertaining enough to warrant a sequel. And sure enough, William Sadler returns to reprise Sloan for the final time in "Extreme Measures" later in the seventh season. Truth be told, however, "Inter Arma" is probably his best episode.
