I can do it, or you can do it. I'm happy to help you out with it if you'd rather do it, or you can help me if I do it. I probably won't have much time to do one until January 9th, as I have a big essay to write over the Christmas break, but I have a ton of time between then and when my classes start on the 26th.
I still feel bad about causing all that trouble with the Book 3 OT -- and now I think back on it my self-ban request was for a really fucking stupid reason too -- so if I can make it up by doing the Community OT I'd gladly do it.
But you staked your claim on the Community OT first, so I'm happy to go with whatever your preference is. So long as KorraGAF is cool with the arrangement.
FYI: I did the Book 2 OT and was set to do the Book 3 OT (I wanted Book 4, too, but I was still banned lol). Wiseblade did Book 1, but he gave me his blessings to do the future ones.
I don't think they had it in mind from the very beginning. After all, Makorra was the OTP until the end of Book 2, when they collapsed it because it was an awful pairing and they had terrible chemistry. I think they may have been toying with the idea in Book 3, and were umming and ahhing on it right up until the end of Book 4's production. There's a lot of subtext in those two seasons to support this argument.
