In general: Thank you all for your questions! We’re working on providing thoughtful responses, especially with those asking about Koh and The Avatar State. Hey, we gotta have some fodder for future dispatches right? : )
As for Sokka. Hmmmm. I would be very surprised if we didn’t figure out what happened to Sokka. He believed in Aang since the beginning, was one of the core trio and managed to be the shining example of excellence amongst those not blessed with bending abilities. It would just feel weird to exclude him. I have trust that we’ll learn about Sokka when it’s a thematic gut punch (just seems like Korra is that type of show), but I’d be okay with a Squeee-moment if we just learn that he’s made a successful line of boomerangs.
