if it wasn't for you, he would have destroyed Pandora's forest and killed the navi, but you are the reason why he changed

even though he is careless, he doesn't want to lose you. He will never leave you, because he loves you

he always protects you, whatever happens he will always be with you

"don't go again.. please, I thought you died"

those are the words that are always on your mind. when you almost get killed on the battlefield for disobeying his orders

he is very afraid of losing you. That's why he forbids you to go to the battlefield. No matter how good your abilities are, he is still afraid of losing you
