The worldbuilding and already established characters did not get expanded or worked upon in any major ways, the focus was much more on side characters.
My personal favourite is Ep2 where we got a new character (a teacher) who was instantly pretty well characterised and the three stooges (Damian and his two friends) got an amazing amount of character-work and all in just one episode.
Unfortunately, not all episodes were that solid. Ep1 had one joke getting abused to oblivion, it was already tired at the 2nd minute, but you had endure it for 15 more, fortunately the last 3 minutes (and unironically Anya) saved the episode.
The episodes that weren't that lucky were 7, 8 and 9; (almost) complete nothingness. Some WB and Yor did a 360 turn (with slight motivation changes), but it was mostly just extensively boring.
To summarize the Season / Cour it was obviously made to expand the existing side characters which it made a pretty good job of. We got some World-Building (mostly about the powers of Bond), but thinking about it, I don't think plot-wise anything happened. (Maybe the Forgers getting closer with Becky.)
I would still recommend to watch it, and while can see someone calling it filler. There was that slight motivation change that could be referenced later, and if for nothing more than the beautiful work on several side-character by itself, it deserves a watch (if you liked S1).
