Can I just say how well this couple illustrates the possibility for harmony between benders and nonbenders?
Because here we have the daughter of a powerful, influential non-bender family whose mother was killed by a firebender, and yet she sacrificed everything to protect the boy she loves - a firebender - because she understands the importance of judging individuals for who rather than what they are.
Gorgeous.
even if he is a juvenile flighty boy (when it comes to the relationship, because otherwise he is very business)
