I just saw the last couple of episodes. Wow.
I really did like how they killed off most of the main villains, giving Zaheer a reason to come back, not just to achieve his earlier goals, but also for revenge; the Red Lotus is still out there, so they could potentially get him to escape somehow.
Something I never really got clear- did Mako suddenly learn how to bend lightning, or did he have one of Asami’s gloves?
I know that magma bending has something to do with having an Earth bender and a Fire bender for parents (or at least have parents from the Fire Nation and the Earth Kingdom), but how is lightning-bending learned/inherited?
Most of the series doesn’t fully follow Korra, but the rest of the group. Korra has run off shortly after regaining the ability to walk(though not really well). She is ashamed of how weak she is, and has decided to run off to train by herself.Everyone else must deal with finding Korra, and defeating the Red Lotus before they can finish what they started.
