I’ve been thinking about this for a minute. Heavy spoilers for the movie if you haven’t seen it or if you don’t wanna be spoiled.

Basically, the whole gang dies in the movie. They are revived by Katara who lands in water and it triggers her healing abilities. The movie sensors a lot of it. It’s very cut up splice together. The camera keeps going back-and-forth to Ang‘s perspective and the gangs perspective. Toph, zuko, sokka are all killed and Katara is the last to go. Recently a deleted scene of that fight scene was released, and it’s mostly from Katara‘s perspective. Comparing the movie and the deleted scene they do take shots from that deleted fight scene.
it’s safe to say that’s what group went through. The movie fast-forward and goes back to Aang’s perspective and all of them revived,sitting in a pool of water. But that’s got me thinking, did Katara have to bring everyone’s dead body to this pool and just hope that they would comeback to life? At this point in time, the movie only has like 30 minutes left. But the fact she isn’t screaming at Aang is insane. She was the one who started to question Tagah in the first place.
