the brief Luke reveal at the end I knew would piss a lot of people off and I was pissed about it too but I now understand the purpose of it after hours of in depth convo. The movie left a lot of things vague on purpose but allows anyone with knowledge of Star Wars lore piece together what's going on and hopefully we are rewarded when the sequels get here. One of the ideas that have to be pieced together would be Rey being Luke's daughter but another one would have to be why Luke went missing. We last saw Luke as the triumphant hero and strongest/last remaining Jedi, 30 years later he's in hiding. Essentially doesn't want anything to do with the galaxy that was his destiny to protect. Why is that? Tragedy? Yeah, the young Jedi at the academy and his gifted nephew using his chosen powers for evil...but what else could he have lost? Maybe his significant other? He failed to protect her somehow maybe. Maybe it was Kylo and the knights of Ren fault she died, or maybe Luke had something personally to do with it. Maybe he flirted with the darks side and is afraid that it may consume him like it did his father. (Remeber Harrison Ford wanted Han to die in RotJ and Lucas chose against it but The writing team granted Ford's wish with this trilogy. Mark Hamil had a request for Luke to actually turn to the darkside in RotJ and Lucas turned it down for that film........) just my theory but I feel like Rey's mother has something to do with Luke's isolation as well as Rey's isolation. I can see a dying mother's request being for her only child, a daughter at that, not living a Jedi's life. I can see Luke having people place her in seclusion because it was too hard for him personally. I can see Luke giving his only daughter he hadn't seen in years a sad and heartbroken look because even when he's tried to keep her away she has still found him and cannot be kept away from her destiny. Skywalker bloodline, a gift and a curse....
