I feel like maybe…
…Bryan wants us to animate Mako doing that dance because he wants us to realize that this whole “hate Mako day” is ridiculous and immature and that Mako is a fictional character and he does what he wants and that people who disagree with the way Mako has been scripted to act should just back off and let the guy figure stuff out for himself.
His decisions and way he has handled the situations in the show so far may not have been the best, but remember that HE IS YOUNG. He is still living and learning and maybe in this upcoming season he’ll learn some more about himself and realize some important things and stuff.
We should just let the guy out of the hate-straight jacket and let the guy dance. He’s pretty good once you let him.
