With all of these theories that Kylo and Rey are connected, perhaps we are being led astray. Clearly, Rey is the protagonist and Kylo is the antagonist. Not every protagonist-antagonist connection requires a sibling relationship, however. The greatest thing about Star Wars is the unpredictable nature of the story. Nobody foresaw Vader as Luke's father. Nobody could predict Luke and Leia being twins. What if, then, Poe and Kylo are siblings? One possibility few have discussed in the connection between the two dark, wavy-haired military men. Perhaps Kylo is a Dameron. Here's a potential spoiler, but it is a valuable piece of evidence in linking the two characters: http://images-cdn.moviepilot.com/im...-reveals-kylo-ren-poe-dameron-more-388804.jpg Spoiler Both members of the Resistance, but then Kylo turned? We saw this in the Comic Con reel. Isaac is sporting the same kind of dark, wavy hair as Driver throughout this film. We "see" the two meet in the recent North American trailer as well. Perhaps the sibling connection lies here.
