Two days ago, we were given the information that the identity of Lin Beifong’s father as well as information on the subset of Air Bending was going to be revealed in The Legend of Korra. I had explained that these two aspects would be revealed in Book 2, but I may have had a bit of a slip-up.
While I was reading Morgan Bannon’s (Airspeed Prime) latest post on Avatar: The Last Airbender Online, he pointed out a very interesting observation: this information was never confirmed for Book 2, specifically. While going over the Tumblr post again that had revealed this information, I realized that Morgan was correct.
Even though we will learn about Lin Beifong’s mother as well as the Subset to Air Bending at some point in time, we can’t necessarily confirm that this information will be revealed in Book 2.
The Tumblr post never mentions anything about this information coming in Book 2. It just says that the information is coming, so that could mean it’ll appear in Book 2, Book 3 or even Book 4.
My apologies for the slip-up, hopefully we receive the information during the course of Book 2.
