Apparently. But I, too, thought it was unnecessary at this point in the series.
During this episode, I realized I just don't care very much (yet) about most of the newly introuced regulars. Rios (has grown on me once I got over his terrible intro scene) and Elnor yes, Raffi and Jurati (even before the murder), no. Narek, definitely no. Soji, sure, but I'm not terribly interested in her character. Even though she's a mysterious "Destroyer", persecuted, innocent yet with superpowers...
The older shows had a lot of time to build up their characters. To think of what DS9 did during the first two seasons with Kira alone... This show does not have the luxury of making us care for the characters.
