The Avatar: Fire and Ash ending is a particularly action-packed one, so it's understandable if some of the finer details of what happens passed you by.
The film is the third in James Cameron's epic Avatar series, which kicked off way back in 2009. This one requires you to remember some plot points from the first movie, as well as what happened in The Way of Water, so you might need to brush up on your Pandora lore. In Fire and Ash, Jake Sully and his family go up against the fearsome fire Na'vi, the Ash People, while also dealing with their old foes Quaritch and the RDA.
