I wouldn't call myself a hardcore Star Wars fan by any stretch (I love the original trilogy, hate the prequels, have watched some Rebels, played some SWTOR, but apart from that I haven't read the comics, books, played any of the other games) but it's interesting to see all these weird theories like Luke being Kylo Ren when it was confirmed maybe a year ago that Kylo Ren would be played by Adam Driver, who is most likely the son of Leia/Han.
