I’m not so sure he is dead. The shot from Thrawn’s blaster left a hole in the ground, so it seems like the Bendu vanished before Thrawn pulled the trigger. Which calls into question whether the Bendu was actually physically present to begin with.

Also, I’m really hoping we get Pellaeon next season. Thrawn’s always been the kind of character who works best when paired with a Watson figure, and with Constantine dead and Kallus defected, there’s an underling vacuum that he could step into nicely.
