Shock and Awe said:
It was definitely a harsh ending, but it reflects what a real person may go through after the battles are over. We can see that the mercury poisoning(the poison was obviously mercury) has taken it's toll on her muscles and if you extrapolate the bags under her eyes to mercury poisonings side effect of insomnia you can get a pretty good feel for where the show may be going with this. I would not be surprised to see a good time skip or a really down beat first few episodes as she tries to cope with the effects, or tries to find treatment.
In addition I am nearly certain PTSD will become a theme in the next season. Another possible explanation for the lack of sleep is that she is suffering not just physically but psychologically from the traumatic battle. She almost died, almost failed the world by being the end of the avatar cycle, almost lost her father, and countless other loved ones. The costs were almost total, and even in victory they were high.
All and all I expect book to be focused around Healing. Not just Korra's physical and emotional healing, but that of the world. The Earth Kingdom must find some kind of peace and the spirits must find a place in the world. We may see an arc where Korra goes almost the opposite extreme from her former completely physically oriented self and finds strength in the Avatar's spiritual role.
Wow. Don't know why I didn't think about that being a thing too. She might be suffering from PTSD as well. After all the Hell she went through in these three seasons I'd be surprised if she wasn't an alcoholic, if she was legal of course. I know I sure as hell would be. I don't know how many times I've done this but counting up what's she's been through far outweighs most of what happened to Aang in the first series. I mean Aang had rough spots he had one truly low point and a bit of a second one with the Day of Black Sun.
Korra's list:
- Kidnapped and help prisoner by a crazy water bender.
- Had her bending taken away.
- Betrayed by her uncle.
- Losing Ravaa and barely able to stop Vatuu.
- Losing her connection with all her past lives.
- Thought her father was murdered.
- Almost killed by Zaheer.
- Poisoned and severely crippled.
- Constantly being told that she is a relic of an old age that needs to disappear.
I'm surprised she's even sane at this point. I probably would've tagged out a long time ago.
