Witnessing this scene like 2 months or so before the movie released felt like early Christmas
The way they just kept threatening each other until they finally realized that they are both equally strong was everything to me
Education time!
This is Tsaheylu.
Two nerves connecting from one brain to another.
There is no sexual aspect to this.
All it does is share information.
Na'vi connect their kurus during mating to share information as a sign of trust and connection.
But it is not in itself sexual.
