In this episode we get our best look at Rex’s clone resistance group, which includes, among others, Howzer (previously seen in Season 1’s “Devil’s Deal”), Nemec (seen in Season 2’s “Tipping Point"), and a new clone called Greer. They are all, of course, voiced by Dee Bradley Baker.

The mysterious Clone X trooper first appeared in Season 2’s “The Clone Conspiracy,” but this episode reveals that there are more. These clones seemingly have no individual names or designations, listed simply as “Clone X Troopers” in the credits. In the script, they are identified as CX-1 and CX-2.

The Teth Monastery location that first appeared in the Star Wars: The Clone Wars movie (2008) has now been abandoned and repurposed by Rex for his clone resistance base.

While former clone commando Gregor is not at the Monastery base, his presence is still felt when Fireball brings in a dish and claims it to be “Gregor’s recipe.”

Commander Wolffe makes an appearance at the end of the episode as a still-loyal Imperial trooper. Wolffe was a mainstay in Star Wars: The Clone Wars, appearing in over a dozen episodes. Eventually, Wolffe would be seen alongside Rex and Gregor in Star Wars Rebels.
