I loved the flashback, and appreciated how Hayden Christenson was able to tap into the version of Anakin portrayed in the Clone War series. Not sure it actually moved the story forward - I'm still not clear what the lesson was he was trying to teach her - but I really appreciate it.
It was very cool seeing Ahsoka struggling with her perception of the Anakin she knew and the Anakin she knew he became.
Yes, definitely too long waiting for Thrawn to appear. My guess is we won't see him until the very end of the second to last episode of the season.
I read an article that posited the final lesson was he taught her how to forgive herself for the blame she felt in Anakins downfall as it related to her leaving him and the Jedi Order before her training was complete in CW. She quit fighting in CW and left the Jedi Order, her training incomplete, so she was never a proper ordained Jedi Knight really. The theme in the flashback was that sometimes you have to fight to keep living, or in a sense 'all this is necessary for evil to prevail is that good men do nothing'. Also Shes been carrying the burden for awhile after learning/confirming Anakin = Vader (Einhorn is Finkell, Finkell is Einhorn!!) was S2 finale of Rebels. Probably a lot of all that really. I think more than anything Filoni felt compelled to tell a story of her finally completing her training and its just a lot of other symbolic possibly meanings put in to it all of which are part true/correct.
Same material also pointed out how Jacen hearing the light saber battle from the World Between Worlds showed that it wasn't all just in Ahsokas head, to some extent it was really happening. Possibly clarifying that this was actually the real redeemed jedi Anakin Skywalker from beyond the grave and not just her mind telling her a story while unconscious. Also why it showed him shifting between Anakin/Vader traits- possibly because he meets her in 'world between worlds', he cannot manifest to her in regular world force ghost form? This would perhaps be a retcon of ROTJ showing redeemed Anakin appear as a force ghost on the regular plain of existence... because no other sith can force ghost freely like that I think? Perhaps because Luke brought him back, he was able to see Force Ghost Anakin in that moment, but for him to never appear to his apprentice Ahsoka at any time makes you wonder. If memory serves, sith always need a vessel like a holocron for any of their spirit to remain? maybe am over thinking it!
FUN though! Agree with you we probably won't see Thrawn til the beginning of the very end of S1.
They are going to be to be on the other galaxy in Ep 6. Will be intersting to see what sets a diff galaxy apart in the SW Uni if anything..
And when they finally get to the point- has Thrawn already built an Empire there? Are there some kind of prevailing alien species that he's aligned with and commands their forces? Has he got stormtroopers arleady of some kind??
In Ahsoka so far, the only other hint of Empire we've seen besides Morgan, Baylan/Shin is the corrupt Correllian Shipyard guys. Kind of begs question where are people like Moff Gideon earlier on right now? I think is only 3-5 years later difference for Mandalorian Events.
