It’s a tricky one. You’re right that the episode isn’t super interesting, though it’s harmless enough. I think it’s in an odd place where you’d watch it if you cared about Ahsoka specifically, but it’s not vital to the Clone Wars.
Since it’s optional I worry that pairing it with other things might drag them down, especially since it’s so slow paced. Ahsoka’s Fall is such a perfect arc that I wouldn’t want to distract from it, whereas pairing it with Resolve (you’d call the episode ‘Birth and Rebirth’) is a genuinely decent idea. They’d benefit from having the same aesthetic, though the relevance (and jeopardy) might be lost at that placement in the chronology.
I think there’re two other options: Firstly, as a (long) opening flashback in the Christophsis episode, which wouldn’t be much different from just watching those episodes back to back; and secondly, dumped in to my ‘Tales from the Clone Wars’ anthology which takes content from a bunch of sources and just sticks them together, to bridge my seasons two and three. (A reminder: I plan to include the other Ahsoka episode from TOTJ, the one where she’s repeatedly trained against clones, in that episode too, kind of as a bridging story. She passes out a lot, which would help with the transitions, and it’d also help explain why the art style is all over the place.)
But yes, not sure. Open to further input here!
