I fel like they feel they never fully explained what is driving her. I feel like I missed an episode along the way (I havnt). This especially stands out as it felt like Korra was going to look at exploring. All the motivation of her past villains and some how come out more enlightened because of it. That theme kinda fell away, I am guessing it will come back but Kuvira is so one dimensional at this point.

Is there just one episode left?

Mako's been such a bit player this season
