Spoilers: Family confusion, please clarify...
So Palpatine is Rey's grandfather. But I could've sworn Palpatine was also Darth Vader's father. That would make Rey a cousin, sibling or half-sibling to Luke and Leia and an aunt to Kylo.
But Rey kisses Kylo... on the lips . It was heavy like when Luke and Leia kissed. The difference here is that Rey and Kylo knew the family tree situation before they kissed.
Am I missing something or was this war of the stars just one big exercise in incestuous frustration?
