To be honest, I liked Makorra a lot more then Masami. I just felt more attraction between the two... but will it happen by the end of Season Four? Perhaps, but probably not. I'd like it to, but I don't think it will happen.
I don't even think Bopal will work out. The entire show since season one has been about on and off relationships. So I think it's a safe bet to assume it will stay the course. Which makes me sad because I liked Makorra and Bopal with the latter a lot more then Boleska.
I don't understand how people are claiming Opal to be a psychotic b***h... she's no where near the same level as Eska in that regards. Nor do I understand how Opal's love is toxic for Bolin as Eska's was due to the way she treated him. I haven't once seen Opal demand Bolin to kiss her feet or grovel at her feet. The worst I've seen her do is understandably snap and ask Bolin to assist in her secret mission to redeem his mistakes (in her eyes) from earlier. Which is reasonable. I wouldn't want my girlfriend going on a secret mission without me. Especially without me.
But Bolin going with Opal gives the two a chance to talk things over. Bolin just needs to grow up and talk to her and he needs to stop being so damn naive. It was cute at first but years have past but he's still the same big ol' dumbass at times.
But back onto Makorra as this thread is for those two, not Bopal... so my bad.
Honestly, I don't think Korra has grown out of Mako. She was just struggling with PDST and wasn't herself. She felt down and felt like the World was against her as she struggled. Now that that is finally over and she isn't suffering from her fears and denials, she can move on and their relationship can flourish.
But I still don't think it will happen. But I want it to happen. Korra needs some happiness more than ever and Mako was one of the few that stuck by her side as she dealt with her issues. Something his brother can learn a thing or two about...
