STAR WARS 7 NEXT TRAILER!

[dafier]

My thought process is still that Luke ended up just going in to hiding, just like Yoda did for the fact that he would only be a threat to Han and Leia. He found out really fast that there are other Dark side users (First Order) who are looking to destroy all Jedi.

If Luke has a connection with Ren, it's one that Ren or someone Ren knows met up with Luke in the past and lost a fight in some type of form. Ren became educated with the past Jedi/Sith and because he is a Darkside user chose to be infatuated with Vader's mission and life. In books and in video games (after EP6) Vader was immortalized with statues and more.
