It is confirmed! There is no shadow of a doubt left about whether or not Korra and Asami were together at the end of The Legend of Korra. Because it is now officially confirmed via Bryan Konietzko and Michael DiMartino's official Tumblrs!
I am glad they did this and stopped the fighting about the topic and gave us this amazing thing that was Korrasami with no ifs, ands, or butts.
Their posts confirm that Korra and Asami was not planned from the start but not much was other then Korra's spiritual arc. Still Konietzko points out that they did not "cave to fans" like some accuse them of as whomever they "caved" to there would be the opposite side still angry.
Konietzko confirms that there was a limit to what the network would allow and they did all they could within that limit. I especially like his refuting the idea this was the end all be all of queer representation.
Was it a slam-dunk victory for queer representation? I think it falls short of that, but hopefully it is a somewhat significant inching forward. It has been encouraging how well the media and the bulk of the fans have embraced it. Sadly and unsurprisingly, there are also plenty of people who have lashed out with homophobic vitriol and nonsense. It has been my experience that by and large this kind of mindset is a result of a lack of exposure to people whose lives and struggles are different from one's own, and due to a deficiency in empathy––the latter being a key theme in Book 4.
It is clear from both of their posts that they definitely had an agenda for including a same sex relationship on the show for their main character and that is fine. Stories carry agendas to share with people new ideas and viewpoints. To change the status quo of something you must approach it with an agenda or it will remain just that, the status quo. Both state this was done also to help LGBT people by allowing them a chance to see themselves in a positive light the same way the heterosexual people do. It may be about 2015 but queer representation is still a small thing, especially at the level of Legend of Korra, a kids aimed show.
