He was undoubtedly joining the council from out there in the Unknown Regions, yes. It would appear that he is still cooperating with this Imperial Shadow Council.Should Hux already be out in the unknown regions kidnapping children etc?
Though he was one if the first to sod off along with Sloane after Jakku 4 years earlier.
I expect the storyline will go something like: Thrawn returns; this Shadow Council welcomes him as the "heir to the Empire"; Thrawn gets defeated, as do the more obvious warlords like Moff Gideon; the remaining Imperials gather together with Hux in the Unknown Regions and build the First Order properly (and spend years converting the heavily-mined Ilum into Starkiller Base).
