IGN: It must be gratifying to see how Rex has resonated. You see more three and four and bigger, truly cinematic story arcs coming out. There's more and more of that, where it's not just little one-offs or even two-offs. So that evolution is taking place as this unfolds, as these stories become increasingly cinematic and the arcs become more cinematic. And then they start recruiting people until you end up with the stormtroopers that we see in Episode IV. And yeah, you start to see that - that Rex is part of the old guard, and the new guard, as Dave said, starts to muddy the waters, so to speak, in terms of the genetics and I think maybe the training. There's no way that they can't deal with that in a meaningful and very important way. My question has always been what happens to Rex and what happens to Ahsoka - those two characters in particular. That begins to reveal itself as his story plays out. Dave Filoni told me Rex is not thrilled with that and holds on to elements of his original armor. IGN TV: This season, we're getting an upgrade to the new armor.

Last month, I spoke to Baker about what's to come on The Clone Wars – where the unknown fate of Rex, who is not in Revenge of the Sith – always looms like a shadow. Continuing to voice every single Clone Trooper on the show is the amazing voice actor Dee Bradley Baker, who is called upon to create the subtle distinctions between Captain Rex, Commander Cody and so many other Clones.

Star Wars: The Clone Wars returns next week with a big visual change, as the Clone Troopers transition into the Phase 2 armor we saw them wearing in Revenge of the Sith.
