The devotion of Reddit fanboys to the Rey Skywalker theory has to be seen to be believed. Some are still hotly insisting that TLJ was a mere misdirection and that in the final film the Truth Will Be Revealed. Because there is just no way Rey could come from nowhere, and not be related to any of the legacy characters, and still have a satisfying narrative arc. There is no way she could find or build a family that doesn't depend on her own genetic heritage and have it mean anything. So if she isn't a Solo (which some thought before TFA came out, and some even thought afterward) and she isn't a Skywalker, she has to be a Kenobi or a cloned daughter of Palpatine at the very LEAST. But really she has to be a Skywalker because Kylo proved himself irredeemably evil by killing Han and will surely be killed in the third movie and therefore doesn't count. THE SKYWALKER LINE MUST NOT DIE.

I love how Rian Johnson repeatedly stuck it to the people who think bloodline matters by showing how messed up Kylo's (and Luke's, and Snoke's) ideas about legacy were, and how much pride and folly and devastation were caused by everyone telling Ben Solo that he had a great destiny to live up to because he was the son of Leia Organa and the war hero Han Solo, and the nephew of the great Luke Skywalker, and the grandson of Darth Vader. Bring on Rey Nobody and the message that the Force belongs to everyone, no matter who their parents were.
