"If you look for the light, you will often find it. If you look for the dark, that is all you will ever see."
This is definitely not exhaustive. I literally was emailing my sister and then accidentally wrote way more than I’d planned on writing, but it’s still not nearly as much as I could (and might) write.
Out of all of the characters, Bolin is the one who, I think, loves pro-bending the most. At the beginning of the season, Bolin was left behind as the only original (well, ignoring Fucking Hasook) member of the Fire Ferrets, not wanting to move on but also not enjoying it without his old teammates. His whole arc with Varrick and stardom showed how badly he wanted to make his own name for himself like Korra and Mako, but he just ended up quite literally taking on a different identity in the process.
That’s why it was so satisfying to see Bolin fighting in the arena. It is was his playing field in all senses of the phrase, and putting him back into that setting really showcased how Bolin has matured since Book 1. He’s innovative, but instead of that creativity being treated as quirky and worthless, it’s impressive. He can fight with pro-bending materials without following the rules (I absolutely loved the announcer guy narrating from his seat.) and his familiarity with the field is a huge advantage. Also, if I’m going to be talking about Bolin was the “home team” or something, I’m going to have to mention the puntential of that, considering Bolin used to live above the arena.
It’s clear that Bolin feels most at home (ha) in the pro-bending arena, but the way that he now has the maturity to use his old skills in new ways also proves that, if he decides to return to pro-bending, he isn’t being being “left behind” by Korra and Mako. There are more ways to mature than to move on from old hobbies. I think Bolin would make a terrific pro-bending coach, or maybe he could even invent a new sport. I don’t know… I just don’t want him to become Varrick Jr. when there is so much evidence that he can be happy and successful doing something that he’s always loved.
