I just want some opinions on this, what do you guys think is Azula's problm throughout the trailer? (OR what leads to her freaking out.)
Let's keep in mind;
Things That MIGHT Make her Happy - Becoming Fire Lord, we know she loves power. However, Ozai may condemn her to this position, leading to some problems.
Things That Might Upset Her - Possible Defeat in 314/315, Being stuck as Fire Lord, whatever the punishment was for lying. (Although, Ozai may not care, since Azula is all he has) or the events of the Finale, which she may not like.
I want some opinions.
