Where's the writers of avatar could hurt the audience without having to kill off main characters
It would be cool if James could invoke horrible suffering on all of us without killing someone. There are so many other ways to break hearts without killing off his characters
Losing a battle and the RDA rips apart the land in graphic detail
Neytiri mourning properly without anger or battle getting in the way
Spiders has to make a decision between the sullies or quaritch (long shot, but if they spend time in the third movie developing a relationship between the two, it might make it impact more)
Quaritch has to fist fight his way through a redemption arc ( this one seems unlikely, but it may happen if i'm lucky, I like his character)
Seeing past characters in eywa, like Tsu'tey, Eytukan, Neteyam.
Death of a bonded, one thing I didn't really like about the first movie is that when seze died they just kind of moved past it, i get it.It was in the middle of the battle.There was no time to mourn or anything but like please, do it again with more emotion this time
Some kind of classic love turmoil? Like if the kids are going to be older in the third movie maybe Tsireya can shatter Lo'aks heart. If the Na'vi are anything like humans, let's face it.The person you were in love with at twelve.You aren't in the same relationship with when you're eighteen (unless your betrothed, which Tsireya may be already since she's the future tsahìk)
Tuk growing apart from her family maybe? Let's face it the poor little girl was born in war times and hasn't exactly had an easy life, she's most likely going to develop some horrible PTSD and it'd be neat to see her blame her dad for it
Ao'nung/Metkayina kids getting closer to the Sully family only to have it all ripped away when they have to leave like they did in the first movie
Making Varang a genuinely sympathetic character, giving her some horrible past that could explain her motivations (provided that she is actually the main antagonist in the next movie, we won't know until we see it after all)
Kiri and her mom. Do I need to say much more there like we got What a minute of the two of them interacting before she had a seizure, let those two hold each other and cry
Something goes wrong with eywa and it effects all the people horribly ( this feels like something that would happen in the last movie, and it would be much more high stakes.You know, dramatic final battle and all that but still an option)
Anyways, this is just how I cope with the fact that I don't want to see ronal or ao'nung or anyone else die, because honestly, it's just starting to feel like an overused plot point in this franchise but I just wanted to put the ideas out there :)
