As much as I love Zuko and his story arc I think I love Azula's just as much and that's because their stories work in tandem.
The beach episode is a really important turning point for her as a character because we see her out of her role of Weapon.
We see her as a teenager girl who struggles to flirt with boys, gets in arguments with her friends, and has a difficult relationship with her brother and who longs for a mother's love that she feels she never had
We see her not knowing how to act as anything but a tool of war. Because that's all she's been taught
I think that episode was the moment I really believed that Azula in the present day of the story did care for Zuko still.
That some part of her wanted her brother back
And after Zuko leaves and the day of Black Sun everything goes to hell for her
Mai and Ty Lee betray her
Zuko is helping the Avatar
Her father is sidelining her
She has lost everything and she desperate and alone and we see her falling apart
Azula is terrifying as an antagonist all through the second season and a good portion of the third. She is ruthless and callous and terribly good at her job
But the writers manuever us as an audience so when she faces off against Zuko in the climactic battle it's not a victory it's a tragedy
Zuko got his redemption or escape. His chance to find himself and who he is away from his awful abusive family
And in that moment we the audience are upset that Azula didn't
Because in that moment we see her for what she is: A teenage girl who had been raised to be a weapon
