This is a (mostly) spoiler-free roundup of information gathered from the new Book 3 leaks. Episodes 3, 4, 5, and 6 were accidentally made available publicly on one of Nick’s foreign sites. Where the spoilers begin, you will see a line of asterisks as a warning.
Judging from the fact that four complete episodes were accidentally put on a foreign Nickelodeon site, Book 3 is completely done and ready to air. It’s unknown why Nick is waiting to do so, most likely for Comic-Con. However, the fact that we don’t even have a release date or any official press releases, news, stills, descriptions, cast lists, anything, and Book 3 is totally complete, is off-putting.
The first six episodes of Book Three: Change, are titled, written and directed by as follows:
301: A Breath of Fresh Air, wr. ?, dir. ?
302: Rebirth, wr. ?, dir. ?
303: The Earth Queen, wr. Tim Hedrick, dir. Ian Graham
304: In Harm’s Way, wr. Joshua Hamilton, dir. Melchior Zwyer
305: The Metal Clan, wr. Mike DiMartino, dir. Colin Heck
306: Old Wounds, wr. Katie Mattila, dir. Ian Graham
(Reminder: since technically Books 1 & 2 make up “Season 1” and Books 3 & 4 make up “Season 2” you may see these listed elsewhere as 201, 202, 203, etc.)
Melchior Zwyer is a newcomer to the franchise, and has previously directed episodes of Young Justice, and worked on animated movies such as Kung Fu Panda (2008) and How to Train Your Dragon (2010).
Katie Mattila has previously written for ATLA, on the episodes The Tales of Ba Sing Se (The Tale of Zuko) and The Beach. Her credit in Book 3 of Korra marks the first female writer of the sequel series.
