I hope there will be a 次 season. I want to see everyone else is kids and what will happen 次 with Korra and Mako and possibility Zuko's kid General Iroh.

There is already another season in the works. There will be 14 episodes and the "Book" is called Spirit.

*General Iroh is Zuko's grandson* but they do have the same voice actor.

yes there is a new season and iroh is not zuko's son

Iroh is not zu-zu's kid thats his grankid but they share the same voice actor
