I am also VERY heavily convinced by my own synopsis of the movie, that Rey is a Kenobi.

You know... It never really said that Ben killed the Padawans from Luke’s New Jedi Order. It just said a “student” did. Also, Leia says at another point in the movie, that they SHOULD HAVE sent Ben to Luke, implying that they never did. So, whether he did it or not is kind of up in the air, if not false.
