you've honestly got to be deluded if you think JJ doesn't "understand" Reylo tho like have you listened to his commentary track for the film? He's like Rey and Kylo's #1 Stan. Like you can hate Reylo all you want and that's fine but objectively you're wrong about JJ "not understanding" it. He's responsible for their dynamic? Like?
who is kylo ren I’ve literally never heard of him before today?
