Oh, I never thought of that, but you're definitely right! Hmm--I was wondering about whether he'd compare them to Luke/Leia but actually I think he wouldn't really think of them as siblings until one of Rose or Paige said something that pointed it out--I mean, he knows it, of course, but to him they're his mother and his uncle, you know?

God--they'd have to be an original character, I suppose, but now I really want a story where Kylo has a sibling himself. That dynamic would be absolutely fascinating, I think, whether they went to the darkside with him, or refused to recognize him as their brother, or wanted to redeem him to the light... Also interesting to think of the effect it might have had on Han and Leia's relationship. I love sibling stories/relationships (I really loved Thor Ragnarok, forex.) Damn, that'd be really interesting. It might even be a point in for the Rose relationship, too, or for humanizing Kylo to himself, as he watches Rose and Paige and is reminded, against his will, of what he used to have...
