Guys, Mako and Bolin grew up on the streets. An incredibly depressing flashback episode about them fighting to survive, and scrounching for food and shelter is practically inevitable.
Just imagine tiny Mako pickpocketing so he can feed Bolin, even though he thinks it’s wrong and hates it every single time.
And Bolin’s always smiling and cracking jokes to cheer Mako up, and maybe one day Mako lashes out Bolin for not taking anything seriously. So, Bolin decides to get a job at a factory to show him that he can help, too. But then he gets hurt, and doesn’t tell Mako until his injury’s seriously infected. So, Mako’s trying to find a hospital to take in his little brother, and they keep getting turned down because they can’t afford it….
And and and… I don’t think I’ll be able to handle any of that.
