Okay, but before all this:
Advisors: Princess Azula did perform the astounding feat of infiltrating Ba Sing Se…
Zuko: Huh? Oh, that’s not hard. It’s pretty nice, if you don’t mind the brainwashing, but you can’t get a spicy octopus for love or money. We ate so much jook. *shudders*
Advisors:… you got in too…. interesting.
Advisors: The mysterious Water Tribe city at the North Pole
Zuko: It’s a pretty place, if you like ice. Lots of sealturtles. They have a really nice little sort of sacred grove thing there, too, I kidnapped the Avatar from it once.
Advisors: …. we have some questions….
Advisors: We still have not found the Fire Lord’s secret supplier of new weapons -
Zuko: He’s at the Northern Air Temple. (Realizing they’re all staring at him) Oh, no, I haven’t met him personally, but I have friends who have. He sounds like a very interesting guy.
Advisors: SO MANY QUESTIONS
Zuko: (while directing post-war reparation efforts) Oh, and we need to send a lot of people to work on replanting the forest around this obscure village.
Advisors:…. may we ask why?
Zuko: Apparently the local panda spirit is pretty mad about having its forest burned down.
Advisors, now afraid to ask: ….Yes, Fire Lord.
Every now and then, the curiosity gets too much and they’ll bring up something like ‘legendary sand benders’ or ‘Southern Islands’ and Zuko invariably produces some tidbit of local knowledge (either his own or gleaned from the Gaang’s stories) and six Foreign Ministers have resigned in fear and the seventh one only barely held it together when Zuko greeted an envoy from a tiny, insignificant Earth Kingdom island with ‘Listen, I am really sorry about what happened last time, I hope the supplies I sent helped with the rebuilding, do you still have that giant eel thing?” IS THERE ANYTHING HE DOESN’T KNOW.
