Akio trying to convince Utena in the last episode that Anthy's suffering is a tragic but inevitable facet of reality and nothing can be done about it despite him being the primary one responsible for her suffering, and this being part of his smoke and mirrors illusion through which he maintains control, acting like his tower is the highest place in the world and he is the end of the world and there's nothing beyond the limits of his power and it's naive and delusional to think otherwise...and Anthy having internalized this idea that there's no hope for her and there's no possible future for her beyond Akio's abuse...and Utena rejecting this ultimately not out of some abstract idea of heroism or nobility or some clear idea of how to fix things but simply because she cannot accept it and she loves Anthy too much to not try to do something...and that giving Anthy the hope and courage to believe in a future where she can be loved and be happy and the strength to choose to leave herself and even subtly mock Akio's own immaturity and self-delusion on her way out the door as she goes to step over the line to the outside world while Akio is shocked because he never considered that his power over her was not absolute and he too believed in the indestructibility of the system he created...the revolution was the power to imagine the future!! the world (the stage) is free and wide!!
