And someone could then take over (for whatever reason), and decide "Hmmm, you know that relationship my predecessors had been teasing throughout season 3 and 4? Yeah, I'm not a fan, and since I'm in charge now, puff. Never happened".

I've seen this occur before, and I don't want myself or anyone else to be dissappointed or angry if this were to happen (granted, the probability is very low, but still).

Look at Star Wars, and it's absurd amount of media outside of live-action films; look at how the MLP comics presented some ideas, then BAM, in one episode the show screws that for everyone; Gandalf going off to fight the Necromancer during the events of the Hobbit was never made clear in the book, but the general consensus was that it occured (we got lucky on that one, albeit it was one of the reasons the movies were stretched xD); The Last Airbender comics, a lot happened in those, but very little has been aknowledged.



Again, I'm very much on the Korrasami Canon Parade. But until we have confirmation ON THE SHOW, aka, in the medium of animation, and is presented as such, it's best to just make it the main consensus headcanon, and leave it at that.
