The McDonald’s french fry
is unbelievable. When you bite into it, you think: It’s so tasty, it
can’t be real. As soon as it gets cold, it turns to lard and flubble. I
mean, have you ever tried to eat a McDonald’s french fry that’s gone
cold? That’s one of the circles of hell. The gulf between the warm,
fresh, lightly salted McDonald’s french fry and the cold McDonald’s
french fry is as great a gulf as any I know. - Viggo Mortensen, Esquire magazine (x)
Them being connected as cousins is just not a compelling storyline, especially when we already have Luke and Leia who are twins, and Luke and Vader who were father and son. Also, Rey didn't feel this connection described about her and Kylo with anybody else. Not with Leia nor with Luke. She thinks Luke was a myth. And why would Kylo only feel this type of connection described with Rey than with his own Uncle Luke and his parents? Why do they have no pull on him the way Rey does? So cousins? No.
