Speculation on what is in the cases that Thrawn's team was loading in to the Star Destroyer? I'm not sure they'll do ysalamiri in this version of the story, but that is my only guess at this point.
Thrawn was really dismissive of Baylan and Shin, and any role they may play going forward, so I'm not sure what he thinks of Jedi.
I'm also unsure what to think of the fact that Ezra seemed to be living so close to all the action. He didn't seem to be hiding all that well, and it doesn't seem like Thrawn to just let him be and not hunt him down. I'll be also interested in how they might explain how Ezra survived on the Star Destroyer during their hyperspace flight and then managed to leave the Star Destroyer when they arrived. Maybe Ezra and Thrawn reached some kind of agreement, or Thrawn didn't want to kill him as he might be their only way back with the Purrgil?
