This season is much more focused and slowly builds towards what is to come.
It takes its time with the development of the characters and their relationships towards one another while not cutting the action out of it. Ever since Crosshair is back the tensions are high as he keeps running into people he has a not so favorable past with, but Crosshair proves himself and that he shows that he is trustworthy. All the while the intrigue of his character remains. There is still so much we don't know about him and what happened to him on Tantiss, but the show slowly chips away that barrier. Through Omega we learn that Crosshair can care deeply about someone and that he is immensely loyal.
However much I like to gush over Crosshair and how he is written, the other clones get their moments. Through Wolffe we still see that clones that are with the empire still believe it is good, but this also begins to change. Rex is determined to get his brothers out of Tantiss and Hunter still has his squad's safety in mind. But with the empire chasing Omega, he is going to have to learn that perhaps facing them straight on might be the better option.
Overall, these episodes set up the final season wonderfully. It includes more important characters without a cheap ploy for nostalgia, ties past plot lines previously thought 'filler' together and presents fans with an animated epic that hits all the right spots. I hope it continues on like this.
