On an unrelated note, if there's one character I loved in Book II, it was Varrick, if only for how hilarious he was despite being such a dick: "Mako, who got you thrown in jail? I DID!"
True, true: they've really formed a tight sisterly bond and it's really cool to see them work together the way they did in Book III, but also seeing Asami comfort Korra at her low points like right now.
