I think the 501st episode is fine as is, except that you cut Cutups death. I’m guessing you did that because they barely react (likely because the Cadets episode was made after Rookies) but I think it makes Domino Squad feel less like a squad and more like a trio. This is kind of why I felt the Citadel was important, because we follow Domino squad until they dwindle down into nothingness, which feels less significant in this version of the show.

On the subject of the poisoning stuff, is it possible that the viewer can just infer that she’s referring to the children Maul and Savage killed when they were trying to get Kenobis attention? Its been a while since I’ve seen that episode so I don’t remember what the specifics were. Personally I think the episode works as is, but the question of why Ahsoka is teaching the students in secret still feels off.
