My guess is that Kylo is the main villain throughout the new trilogy (what is this called any ways, the sequel trilogy? ST?). I think Kylo is Han/Leia son and Rey is Han/Leia daughter. My guess is Kylo kills Han in Episode 7. He kills Luke in Episode 8. Then a brother vs sister duel in the final movie, in which Rey wins.
Awwww sounds like the EU.I love it!
