I think skipping maybe a week would be alright. I assume we'd skip to the day Katara leaves, Lin will make an extra visit to see her go, as well as see how the others are doing.
I think we could assume by the next week, Asami and Mako are maybe on their first date? We could write that out while we write out Tenzin and Lin sharing some conversation about the leads and more cases popping up as well as now reports slowly coming in with people knowing bending (either paying for it if they're wealthy and know Xano/Xana OR being good people and being injected at night?). I'm not sure about Korra and Bolin though. Do you think we could say the city is pretty much rebuilt thanks to Asami's mechanical help, as well as the benders of the city? Do you think they'd be back to practicing pro bending? I also think it might be a point when Asami shows off her fire bending to them? I kind of picture Korra, Bolin, Mako, Asami, Tenzin and Lin all by the dock where the boat is leaving. Asami says she can bend now and she and Mako are on their first date, Lin and Tenzin are going to discuss how he's doing over tea or lunch, and maybe Bolin and Korra are going into the city to pro bend abit now that the arena is rebuilt?
I'm only supposing though, did you have any ideas?
