So our Bolin is in conflict about whether or not Kuvira is doing the right thing, and in turn, if he’s doing the right thing following her. Kuvira has him convinced she’s doing good so far and it’s lead to conflict with Mako and Opal.
But we, the viewers, see how Kuvira gets what she wants. It seems she leaves anyone that does not join her open to bandit attacks and starvation. It’s implied she hires goons to cause trouble until she gets what she wants. Kuvira has also stated that anyone against her and her empire will be crushed.
Who is going to be crushed indeed. Bolin and Mako’s grandma, Yin, has shown loyalty to the deceased Earth Queen. Kuvira hates kings and queens and Yin so happens to adore a queen. What’s to say she won’t stand against Kuvira and her empire? She may do just that and be put into a situation in which she dies. Whether it be hired goons, left to die to bandits, or starvation, this seems like the only thing at the moment that would have Bolin break way from Kuvira.
It’s been 3 years and it doesn’t look like Opal has been able to get him off Kuvira’s side. Mako is currently working for Wu, defends him, and is against Kuvira. Because of that, Bolin is distanced from Mako.
Bolin currently thinks he is doing good with the thought he’s helping poor people LIKE his family. It has not been stated yet that his family is okay and it’s been implied by him that they are still poor.
I feel it’s unlikely because of how dark it would be, but what if Mako and Bolin’s family are wiped out by Kuvira because Yin refused to submit? Bolin could be assigned somewhere else when it happens and Mako would probably still be in Republic City. When the news finally hits, it’s even worse than when their parents died and we may finally get some tears out of Mako.
*Cue the incredibly sad scene where Bolin brings back their father’s scarf and gives it to Mako as he breaks the news their family has been wiped out.
I am not expecting something of that magnitude to happen but perhaps something similar. I do not think Yin’s attachment to the deceased Earth Queen is just a gag. It seems placed there for the purpose of conflict with Kuvira. So I won’t be surprised if someone from Bolin’s family dies or at least forces Bolin to stand up against Kuvira.
