I even wonder if this series (at least the first season) is necessary for the mandoverse. Honestly, depending on how things go until Filoni’s film, perhaps it could be completely skipped in future fan edits.
Firstly, this series appears to have almost no connection to Ahsoka’s appearances in Mando and BOBF. In Mando she questions Morgan about Thrawn, and this was not addressed in the Ahsoka show. In the series we find out that she trained Sabine, but this is not even mentioned in Mando and BOBF. Now we find out that she was conflicted, but that hasn’t come across in her appearances so far either, because the character is completely different in this show.
Secondly, everything points to Ahsoka returning with Sabine in a possible second season, which in theory would make her trip to another galaxy something “skippable” in an edit. Thrawn’s return is the type of information that can be reported in a crawl, for example, as well as the information that Ahsoka has a padawan.
I would really like to have seen a more character driven season, as Ahsoka from the animations is a very good character. But unfortunately, the character development was the series’ biggest flaw, in my opinion.
