Yes that could be fun... especially if rehabbed Azula also likes her diapers and can diaper Katara as well. We could do something like have them hanging out at the Ember Island beach house, playing in diapers, using their diapers in front of each other, changing each other and so on
Dany & Sansa might be interesting to RP sometime. I generally don’t RP with underage characters like Arya.
