The fact that Mizi's eyes are called "love eyes" makes it all the more painful because her eyes don't just show how much she loves Sua, but also how she expresses her true feelings after losing her sight. She's become completely empty and lifeless.
This is how I think the zuko movie is gonna go:
Zuko: wow, being firelord is so much work but i love my friends and i love my family.
Mai: I just won "teacher of the year" for the 10th year in a row. I love my job.
Izumi: goo goo gaga
Tyzula subplot:
ATLA fans want Azula hanged for smirking here but have no problem with Iroh just STANDING there doing jack shit, even though he knew how crazy his brother was.
They can forgive inaction, but smirking? That's to much HANG HER
