Ya’ know how Katara (Better then Pakku) can keep up with Aang’s and Sokka’s antics? Look at Wang Fire, and when Aang was the old dude I like to believe that she can also fully lie to Toph due to being able to be completely calm in such situations, and a great hi jinks partner, but chooses not to because Katara would feel guilty for being able to do so. Tl:Dr Katara can lie just as good as Azula and get by Toph’s seismic sense.
