I'm curious as to the story behind what seems to be robot spirits, because I'm pretty sure it's not something left over from Korras trip to Cybertron.

>dealing with the unagi - "Nobody likes the unagi but me," Korra grumbled to herself.

And Kyoshi, going by that fancomic :)

>To paraphrase Atomic Robo, "Well, that was like placating him."

And frankly, I'm still of the belief it's the best way to deal with the idiot.

>Jianyu Beifong - Jianyu is descended from Suyin Beifong's oldest son Baatar Jr.
>(an architect/engineer) and Kuvira (the head of Zaofu's City Guard during the
>170's and an extremely skilled metalbender).

I liked book 4, but there's something so very pleasing about knowing there's a universe where those two got their happy ending, as opposed to Kuvira going a bit overboard with trying to stand in for Korra.

>you cannot be serious - Oh, Tenneq. You never studied.

And he'll never learn.
