The Star Wars universe is no stranger to dark subject matter in both its live-action and animated narratives. Throughout the movies and shows (and I assume the canonical comics and books that I still have not read), the series takes us to some really gruesome places.
One recurring character in both The Clone Wars and Rebels is Rex. A war veteran, Rex is a capable and valuable member of the Rebellion and probably the most well-developed clone in the Star Wars universe. One of the problems with having a story filled with so many characters, though, is that the narrative doesn’t always have time to fully delve into their issues. At the very least, though, Star Wars tries, and while the story occasionally rushes through certain character arcs, its results are not horrible. This is most definitely the case with a recent Rebels episode “The Last Battle”, where we finally get to see more from Rex and his PTSD from fighting in the Clone Wars.
