Aww, everyone's growing up. I really like the new Airbender outfits, and the idea of them patrolling the world and helping out however they can is a really nice nod to what the Gaang used to do. Mako having to be Prince Wu's bodyguard is hilarious as well, I look forward to seeing more of their adventures.
Kuvira is absolutely something else; awesome and scarily competent. It'll be interesting to see how things go once Korra is back to her old self. And Korra, aaauw, making me cry. I know this is more for the next episode, but I really admire how the show portrayed her struggle with everything. I tend to forget or take for granted just how unique this show is compared to what else is available on tv. I'm really gonna miss it.
