This is where the Legend of Korra series really starts to pull away from the standalone episodes. The first three episodes set things up – episode one brought Korra to Republic City and hinted at the problems the city faces. Episode two introduced her to her training, both the traditional methods under Tenzin and the modern methods with her new friends Mako and Bolin. Episode three introduced the series villain, Amon, and demonstrated just what kind of a threat he is.
Episode four attempts to move forward, conducting the last of the setting up and moving the overall plot arc forward.
The problem is there there’s a lot still to set up. There are several threads running through this episode, leaving it feeling disjointed, jumping around.
The threads in this episode can be broken down into three key subplots: Korra vs Amon and her own anxieties; Councilman Tarrlok’s powergrab and manipulations; and Mako’s introduction to and fledgling romance with Asami Sato.
