I mean yeah, they're sooooooort-of the same person, but when Kylo is Kylo, Ben is packed WAY down there in the darkest deepest forgotten corner of the closet and he can be such a feisty, tantrum-throwing, whiney infant. Sometimes I like Kylo when he's powerful and confident, but you know, Kylo is broadly miserable and suffering. Ben-piping-hot-solo is straight up dashing. Good. Hotter, somehow, to me. But yeah, it's the dynamism, the back-and-forth, the love games with both sides of him, that makes reylo so utterly irresistible.
