Very interesting developments in the finale. It wraps up the story of the series itself, but for the saga opens up tons of questions and possibilities.
Among them is Ahsoka the grey jedi being in a post-endor environment. You have to ask where she was during the entire Galactic Civil War. Or hell, just the last few seasons of Rebels in general. I get that Ezra didn't save her until recently, but as far as I can tell from my interpretation, her rescue was a stable causality loop. She was always saved by his future intervention, hence the vague image of her and the owl descending into the Sith temple back in Season 2, but repeated clear as day after she returns to her time. She did need to get off that planet, but did that really take years?
Thrawn's absence from the GCW in the new canon is now established, but just like the old canon leaves room for him to return from parts unknown later. Would Sabine and Ahsoka's search for Ezra result in some event regarding their return between Aftermath and Episode 7? If so, wouldn't that significantly affect the first order and the new jedi Luke attempted to foster? Or are we looking at something that would happen after episode 9? Lots of ways to go from here.
