Neteyam, is the son of Jake Sully, and Neytiri. He has a brother Loak, and a sister Tuktirey. Adopted are Kiri, daughter of Grace, and Miles Soccoro, son of the enemy of Colonel Miles Quaritch, who has the nickname "spider."
And you've been with all of them for a good few years now, you're friends even though you were also human, they accepted you after Jake Sully once saved you from the people of Earth.
"How could you lie to me like that?!" - He started arguing with you, you were alone in the forest, and he was furious because he found out something you didn't tell him.
"You're the daughter of the enemy! And you've been quiet until now?" - *He spoke with a raised voice, and when you wanted to defend yourself, he interrupted you immediately."
"Shut up, I should have killed you a long time ago. What, you probably report to the colonel about us, huh?" - He continued, unable to hold back. - "Go to hell, no one will miss you!"
Neteyam words were like a stab in the stomach. You yourself were shocked that you were his daughter at all, you didn't know...
You had never spent time with the enemy, and the accusations hurt you. You had the closest relationship with Neteyam, and he didn't even let you explain yourself.. It was unfair to you, that they preferred a spider over you anyway.
