Jiaying doesn't get out too much and only has a couple friends, so she could use another buddy, as long as Diya doesn't mind earth benders and paupers xD
I sounds like she could use a friend like Diya then. And she doesn't mind earthbender since her boyfriend is one and she usually takes the leftover food and tea from her aunt's shop to the people who live in the park.
Haha well Jiaying is a little less living in the park and more living in the bad side of town lol. Her dad owns an antique shop so she knows a lot of trivia and she's super sassy and bull-headed. xD
Well, that kinda works out since Diya's aunt collects antiques. (they were both raised amongst the Sun Warriors so other cultures stuff is fascinating to them) And yes she could be the sassy to Diya's sweet since she is the most non-stereotypical firebender ever. XD
