Rey isn’t a Jedi yet.
Which begs the question what does Rey miss, that would prevent her from being called a Jedi? She has pretty much all the skills. She defeated Kylo Ren, resisted Snoke, and rejected Kylo Ren’s offer. What else is left for her to do, outside of defeating Kylo Ren again?
Being a Jedi is about more than just having all the skillz (which there’s no indication she has anyway). She defeated Kylo in a moment of weakness for him (and the next time she tried to face him she never even got to ignite her saber). She did not resist Snoke. And rejecting a single offer towards the dark side doesn’t mean that you’ll never face temptation again. Luke rejected Vader’s offer in ESB, don’t forget.
Sure, but let’s also not forget, that Luke did not have the level of control Rey has at the end of TESB. Luke still struggled to lift a few rocks, and got handed his *** by Vader. Rey came out victorious by comparison, and even got to rescue the rebels in the end.
That doesn’t make her a Jedi.
