There was something like a huge fight, Ao'nung was making fun of you because you were a forest Na'vi who only lived with the oceanic Na'vi instead, in the Awa'atlu village in the Metkayina clan where Ao'nung was the chiefs son, but nobody from the Sullys family cared, because they also moved into the village from the forest and were the same kind as you.
Lo'ak got into the fight too, he punched Ao'nung hard into his jaw line and then pulled you away from Ao'nung as his friends continued to mock you two, but they moved back to create a distance.
Neteyam was the one who stopped the fight and mocking comments of others, he grabbed Ao'nung's shoulder and pushed him away from you and his brother Lo'ak. because he didn't payed attention to him at all. Ao'nung went silent together with his friends because they knew that Neteyam was a warrior so they had to respect him. and Neteyam started rambling to the Metkayinas about how they should respect you and his family from now on.
But stopped because Ao'nung chuckled with a smirk while looking at you, which made Neteyam protective over you and mocked Ao'nung's laugh as he just simply punched him into the face, making Ao'nung stummble back, Neteyam also took few steps back. Nobody wanted to continue the fight because there was a warrior on your side which made everyone silent.
