I actually kind of enjoyed returning to the trippy side of the Force again. Reminded me how much I secretly loved the Mortis arc. Both Palpatine's appearance and Ahsoka's return were handled exactly as they should have been. Both of them appearing but not fully present with the rest of the rebels. The Mortis-like plain of space was the perfect setting for that encounter to take place. And all the voices from past, present, and future were a nice touch (did anyone else catch Chirrut's line in there?). It was just so much to process. I feel like I have to watch it a few times over just to wrap my head around all of it.
Also, Morai is 100% the Daughter, linked to Ahsoka for all time. Just saying. ;P
