I had a thought--a stretched thought. Rey's journey is basically the Force pulling her for an embrace, because balance is in imbalance, and the Force seeks union. Kylo Ren is highly Force sensitive, enough to feel someone he can't see or hear, but knows they are within his proximity. Because the Force wants balance, the Force itself desires Rey. The insidious thought I had: perhaps Kylo channels the Force's yearning, since he's so attuned.
Christ on a cracker, I love the way you tHINK. ♥
