I was informed I might have hit too close to home and didn’t want to spoil anyone.  But I’ll post my thoughts under the cut:

Rey is the daughter Han and Leia thought was dead, perhaps left behind by Luke on Jakku for her own safety from her brother, Kylo.  It’s possible Rey is not her real name (what it was Padme or such?).  Luke was terrified of what Kylo is capable of and will be even more terrified of what Rey can do and is reluctant to teach her for that purpose (he will, anyway, he’s the film’s Obi Wan).  

Rey will learn her real parent’s identity, knowing she met her father, but he was killed by Kylo in front of her (and it looks like he’ll kill Leia, too), knowing she was so close to a reunion, will set her a possible path to the Dark Side, wanting revenge, and the third film will close with Kylo’s death (after he’s achieved some kind of ill-gained redemption that only white male characters can achieve) and Rey gets to pass on her Jedi training to a new generation or something similar.
