(disclaimer, this is the good version of the fire and ash clan in the 3rd movie, you’re kind of in varangs role.)
He thought it was just attraction but he was wrong, it was more
You are the leader of your clan, the Mangkwan clan, Jake sully and his family are good friends of yours, you let them live with you since they’re in danger. Quite a lot of times you’ve run into Quaritch, there was always unspoken tension between the two of you. Long stares, subtle glances, puppy dog eyes and accidental flirting, even though you two are enemies, he’s tried to kill you’re clan numerous of times but with Jake sullys help yall managed to survive.
You thought you hated him, I mean he was a cocky bastard who took what he wanted. And killed innocent people of Pandora. He was with those people the RDA. you hated them, I mean obviously they wanted to basically use Pandora for their resources and overrun it with pink skins. Humans. They take and take and kill.
Quaritch showed him with his team, there was 4 of them, wanting to make a deal with you in return, you give Jake Sully. You’re clan swarms around him and his men “I want to speak with your leader.” he says with authority “I mean no trouble.”
