Ahsoka is looking for Thrawn again (will discuss later). But isnt that odd? Why would she go for any random person to find Thrawn? She isn't finding some random person thrawn bumped into at a cocktail party during the empires reign and have a conversation with. The magistrate made her money off of building star destroyers for the Empire. Even if she's retired now which is a possibility, this is someone that wouldn't meet with someone like Thrawn. The empire was very anti non human. So in order to keep that up there's no way that the empire would have a non human high ranking official discuss and coordinate building of star destroyers. And why would Ahsoka go to a old contractor for the empire to find a high ranking official of the emprie who got lost in the unknown region of space? She isn't gonna give Ahsoka a map or anything. And if the magistrate is retired who's to say she can't un retire and start bulidng destroyers again?
Thrawn: Thrawn is back in play again. Ahsoka wouldn't look for him anywhere else then close to the unknown region of space or find people who do know how to find him there. Ezra could be dead or not. But if Ahsoka found Ezra that means she found thrawn or knows where to look. If Ezra is dead then that's no help to her quest, but if she's still looking for Ezra she wouldn't stop to find thrawn who she presumes dead after the end of rebels. There's no logical reason unless Ezra's found or dead and is back and causing trouble. And why isn't Sabine with Ahsoka looking for Ezra? Sabine was helping Ahsoka so she had to have found him or he's dead or the search didn't work.
Maybe Sabine split up to cover more ground. Okay that's possible but Ahsoka wouldn't look for the guy Ezra presumably killed. Maybe she figures both are alive? Then why stay on a planet long enough for Bo-katan to be able to point Mando where she is, and track down a old ship builder for the empire? That's like the last person who would know. Unless Thrawn is in play again. And notice how Ahsoka is is clearly fine with telling Mando she's a jedi. She had made it clear time and time again after the bombing scandal she's not a jedi. And this isn't a simple mistake because the literal creator of Ahsoka was the director of episode 5 of season 2 of Mandalorian.
Thrawn: Thrawn who is back in play was last in the unknown region of space. And Ahsoka's best lead is a ship builder for the empire, and Moff Gideon a non Force user looking to become Force sensitive possibly is getting intelligence from a very good source. Both of these connect to Thrawn at the very least one does. Thrawn is trying to take over the galaxy. We see this in Legends where he tried that once. And Mandalorian is pulling from Legends as inspiration. And Mandalorian is like conisderd a sequel to Clone Wars and Rebels. What better way to up the stakes, keep fans intrigued and make up as a apology for the movies 7 8 and 9. Plus, why would thrawn be connected to the emperor who everyone thinks is dead? Why not keep just building star destroyers in the unknown region and hide out when you have the element of surprise? The emperor was clearly able to build them without anyone knowing. Not even the first order. So you aren't gonna contact a old contractor (the magistrate) to do it. And even if the magistrate would do it would she even have the stuff to build the empror's planet destroying star destroyers (try saying that 5 times fast) everyone would have found out by now if they did it that way. If Thrawn is in the galaxy again with possibly contact with a imperial remant and definte contact with a person who built star destroyers for the empire, then he's getting a army ready for something.
And another reason it can't be the emperor or the first order he's serving is because if they have him in a future show and he's stopped, that wouldn't make for a climatic ending. All this build up to lead to the destruction of on gernals plan? That'd just be shown in one show and its very unlikely they show that in The Mandalorian. Thrawn won't play second fiddle anymore either. Not when there's a power struggle after the empties collapsed and he can take what he wants to build his empire, even if he finds out the emperor is alive
He just has no reason to. And Thrawn being so smart knows that a simple planet destroying ship won't work. It won't scare people anymore after 2 got blown up. And even if he had a thousand like the emperor did in episode 9 there's millions or billions of worlds you have to destroy. You can't just destroy one world anymore. And with not as many forces what does a cunning thrawn do? He makes genetic super soldiers.
Which is possible. Clone troopers in the Clone Wars are, well clones. Several people close to Gideon have Kamino patches on them which is where the clone troopers where made and we see Dark troopers which are super soldiers from Legends. And we know clone troopers can be made to age twice as fast to be ready for battle. So they can so the same with Dark troopers with even more advance technology seeing as technology advances since the time of the Clone Wars. So why not take lessons from the past and use what the republic did, and get ready to take back the galaxy quicker then just building a regular army.
Ahsoka is looking for Thrawn who is back in play making a new army of clones and Moff Gideon who could be working with him is helping undersee that happen and is potentially trying to become force sensitive and might be in a Darth Vader cult. Ahsoka is attempting to stop thrawn and has found Ezra dead or alive. Baby Yoda might be able to join in and this will be a big fight against Thrawn perhaps in something like the rumored Ahsoka series that would be on Disney+.
