Question: I've got two questions 1)What Neytiri meant when she said that she mated with Jake before Eywa? 2) How did Tsu'tey know that Jake and Neytiri have mated?
Chosen answer:(1) Neytiri means that she has bonded with Jake in the eyes of their deity, that, by Na'vi tradition, they are effectively married. (2) Jake and Neytiri show up holding hands, and it's clear that Tsu'tey, who was already suspicious that they had an affection for each other, spots it. He's not stupid, he can work it out for himself.
