Where do I even start. This episode may have broken my heart, but I guess I can understand why the writer’s did what they did. It says a lot for Mako’s characterization, and even if it makes us shed tears….Mako just wants to be needed.
Bolin has left him, moving out, fighting with him about Varrick because for the first time he’s the one making the money, he’s loved and adored and not in Mako’s shadow. So, Bolin doesn’t want to hear that Varrick is a bad guy, and I think Mako sees him as his naive little brother, and so that’s why he doesn’t push the matter more than he did.
In regards to Korra, well, it’s been a week and he hasn’t heard from her. He has no way of knowing that she’s washed up on an island without her memories and meeting the first Avatar. It’s not like Desna and Eska swung by Republic City to go, “Hey guys, btw, Korra got eaten by a dark spirit. See ya!”
Mako is stubborn, and he is the type of person that needs to be needed. He needs to fix people’s problems, and since he can’t fix Korra’s anymore, he’s going to fix Republic City’s. Because even after the interrogation room scene, he’s still in his uniform. He’s still doing his job. The same job that lost him the person he loved.
And at first, he probably hoped that Korra would cool down, she’d come back and they’d both be stubborn but finally make up. But it’s been a week and no one has seen Korra at all. So, Asami is there, needing to be protected.
And Mako is the guy that needs to be the protector, the savior, the one that can fix the problems. He can’t do it for his brother anymore, Korra isn’t there, and Republic City doesn’t want to listen to him.
But maybe Asami would, given time.
So, while I dislike the kiss between them, I can understand where it comes from on Mako’s end
(who the hell knows why Asami is still pursuing him though).
