Here’s some more foreshadowing via camera framing for you guys.

Everyone the camera focuses on when Chief Arnook gets to this part of his speech leaves he North Pole in one way or another.

Princess Yue dies (err, her physical form dies but her spirit lives on as the Moon), Hahn presumably dies as well (although he’s a one time character that was only meant to be a rival for Sokka…but, he was thrown into the ocean with Fire Navy ships everywhere, so…), and Pakku travels to the Southern Water Tribe to help their sister tribe rebuild.
