After seeing it i will probably chalk it up to the best episode of the book if not the show in general, it really brings Korra conflict into perspective and hints at what the true purpose of things we have seen so far. Korra’s amnesia also has a rational explanation that makes sense with everything that happens and doesn’t cheapen her character. Most importantly it is bar none the most beautiful piece of animation I have seen from a TV show and really highlights how great Studio Mir is.
