I think it's an organ. That's how it had a similar sound to Interstellar I think. And it really fits Thrawn. I hope that's his theme on a soundtrack or something.
I kind of also thought Thrawn was going to have a force sensitivity and notice Kanan at first, but was glad they didn't do that. I still hope they do Ysalamari's, but Hidalgo says it's unlikely. He doesn't like the idea of them is why, I think. God I wish I had his job.
I hope we get to see others. Akbar in the EU is Tarkin's slave working on special projects, so maybe they'll do that storyline? He's supposed to be one of the ones who designed the B-Wing, but they made that new Mon Calamari for that. And I think Biggs is an obvious choice once they're closer to ANH.
Maybe she will. They'll probably wait to the last episode of this season though. Hype it up a little.
In R1, they should have the Ghost in the background somewhere. I'd love to see the ship in film 3d. (I'd prefer a full set like the Falcon, but a model would be fine too) They could do just Hera walking up and reporting in as a cameo and that would be cool.
Oh, and a heads up, you might want to avoid the DKSW stream, we're going to have spoilers there. But I won't submit any or talk to you about the spoilers. I know you want to go in pure for the film and I'm not trying to ruin anyone's experience. Some of what we posted there today are spoilers though okay?
Just thought I should warn you Sith. :{D
