According to the name supplied on concept art, this Zygerrian seen in the episode is named Omus Krill -- although this particular uniform seen in the art is the outfit worn by Anakin Skywalker.
The design of the Kadavo slave processing facility -- suspended above a volcanic caldera -- was an idea originally developed but left out of the Ryloth episodes in Season One (see inset concept art).
Of course, you all should have spotted the visual and music nod to Return of the Jedi, when Luke Skywalker gives a jaunty salute to R2-D2 -- mirrored here by Anakin Skywalker. If not, into the Sarlacc with you!
The plants in the floating planters in the Queen's throne room and verandah are actually sourced from some of the vegetation seen on Mortis in Season Three.
Also from Season Three is the deceitful Banking Clan executive, Nix Card, seen in this episode at the Zygerrian slave markets.
