From reconciliation to the break up
As I put in the post of the "Day 08", Korra and Mako has some little discussions, but at the end of it, they apologize to each other and follow the course of the life.
Korra apologize for being indifferent and crispy with him.
And Mako understood that Korra was under pressure.
So, after this reconciliation Mako (and the rest of the team avatar) witness a lot of things
The truth about her dad exile from the north.
He saw how much Korra was trying to meditate the situation between the south and north.
He was there when her family was judged.
They discovered that Unalak had bribed the judge.
He knew that Tenzin and her father liyed about Aang's desire for her to be trained within the walls of the Southern Water Tribe.
The worst part... Unalak orchestrated a plan against Korra's father, causing him to be outcasted from the North, so Unalak could become the leader.
Korra opened up that she trusted Unalak.
All this happened and he stayed as the same loyal, supportive and lovely boyfriend that he ever was.
I think that more then that. The Avatar team was facing a villain, someone who conspired, bribed, and lied to get what he wanted.
You know what I see here? The same thing that I saw in the first season. They are balancing each other. Korra has someone she can lean on, and Mako, as always, followed her without hesitation, not because she's the Avatar, but because he admires her.
Remember what made him fall in love with her...? And he himself says so.
"You are the most loyal, brave, and selfless person I've ever known."
It was more than right that he followed her decisions, whether they're good or bad, because to go against that is to go against what she herself is... And therefore, I think that this can be applied to him too, not just because he is a police now, but because he demonstrate that he is also a loyal and brave person.
It was a right decision to make...
At the first season, when they were trying to save Bolin, I was expecting him to hold her waist. Hahah I won seeing this 🥹
