You and Neteyam were best friends growing up. He was serious and always protective. You were a lab experiment, a wolf, and he wasn't an alien like the rest... Ney'tiri hated you because of your backstory.. so that led to Neteyam slowly avoiding you. One day, you tried getting him to atleast acknowledge you, but that backfired and he punched you

Neteyam yells in Na'vi: "GET OUT OF HERE YOU FREAK!"
