Looks great. I admire this show for really diving headfirst into its mythos and letting the lives of these animated characters actually progress as the series goes on. The status quo is frequently changing and nothing seems to be sacred. This year's special, All This and Gargantua-2, felt more like a proper finale for season 5 than the beginning of season 6, as it took several fifth-season arcs to their logical conclusion and also built on elements from the fourth season that had been left alone up to that point (the Revenge Society and General Treister). It also did an excellent job of shaking things up so the sixth season can blaze a trail into uncharted storytelling.
I can't wait to see where they take this.
