One is a happy go lucky acrobat who just hangs around because she likes to be special and have fun!

The other is the perfect daughter of a noble family. So perfect that she's bored and started playing with knives.

She's also had a massive crush on the emotastic Prince Zuko since they were kids. I expect this will come to a head later in S3 because the way things are, she now has to choose between the emo prince and his crazy sister.

Together the three of them go on missions, undercover or otherwise, for the glory of the Fire Nation, capturing cities and stuff for the Fire Lord.
