The battered rebel helmets littering the cave floor on Geonosis are the same commando designs seen in Return of the Jedi and Rogue One: A Star Wars Story. They sport Saw Gerrera’s symbol, seen on his tattered cape in Rogue One.
The battle droids encountered in this episode are a literal mix of the tan-colored units and the rust red Geonosian units.
Saw Gerrera in this episode more matches the “flashback” version of Saw seen in the opening prologue of Rogue One: A Star Wars Story. Sometime over the next two years of his life, Saw will lose his leg and develop a debilitating breathing problem.
In Star Wars: The Clone Wars, Saw had piercing blue eyes, while his live action incarnation had brown eyes. This version is somewhere in the middle, with green eyes.
Ezra’s scout trooper helmet has undergone a Sabine Wren-redecoration, complete with phoenix starbird symbol and a stylized Loth-cat face if viewed from above.
Imperial Captain Brunson is named for the series Look Development Production Coordinator Jessica Brunson.
Klik-Klak proved an opportunity to do something never attempted before: create a sympathetic Geonosian. The production team pointed towards District 9 as an example where an insectoid alien could be turned into something other than creepy through portrayal and circumstance.
The jetpack-wearing jumptrooper is based on the flying stormtroopers developed for Star Tours: The Adventures Continue.
The ongoing gag in the episode is Klik-Klak is literally drawing an image of a Death Star, yet everyone plausibly interprets as something else (rings of Geonosis, an egg, the gas canisters).
Sabine’s jetpack has been customized with a new paint design.
The revelation of the toxic gas canisters is a story thread that has been slowly playing for years, starting with the disappearance of the Geonosians in Season One of Star Wars Rebels and including a visit from Darth Vader to the seemingly dead world in the Darth Vader comic series. That the comic series depicts a queen suggests Klik-Klak nursed the egg to hatching.
