These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Ozai already fell under this category in the series. Believe or not, he actually seems worse.
Fridge Brilliance: Azula's mirror hallucination in the finale wasn't just a hallucination, it was a flashback of Ursa finding her in Ba Sing Se.
On that note, Ursa isn't able to get through to Azula until she learns to trust others as well.
Moral Event Horizon: Ozai, obviously. Zhao also crosses it in a brief appearance when he tortures Ursa with red spider-fly venom with the intent of using her against Zuko.
Nightmare Fuel: Ursa's nightmares about Ozai are genuinely frightening.
