'Star Wars: Episode 8' spoilers: Kylo Ren may not be the next Darth Vader

Rey (Daisy Ridley) could be the Sith Lord in the making that the galaxy far, far away should prepare for, according to the latest "Star Wars: Episode 8" theory.
In a new speculation explained in detail by The Guardian, the scavenger from Jakku could be the next Darth Vader. This could be the reason that she knows her way around the Force even better than Kylo Ren (Adam Driver).
One of the glaring issues of fans with "Star Wars: The Force Awakens" is how Rey appeared to be quickly adept with her Force abilities rapidly while it took time for Luke Skywalker (Mark Hamill) to reach the level she reached in the film in a matter of minutes.

It is speculated that this could be because Rey might be a reincarnation of Anakin Skywalker and her path to the dark side could begin in "Star Wars: Episode 8."
If this is the plan for Ridley's character, it will certainly be interesting to see the dynamic changes between her and Kylo Ren, who has idolized his grandfather all his life and has done everything he did to continue his so-called legacy.
"Star Wars: Episode 8" should see a more Force-skilled Rey as she will train with Luke in the planet Ahch-To, where the Jedi master stayed after his failure to hone the skills of his Padawans.
Should Rey come out as the new Darth Vader after all this training, it will once again be another heartbreaking moment for Luke, who isolated himself in the first place because of that.
Of course, this is only mere speculation. Not much is known about Rey at the moment except that her parents left her in Jakku, she is a good pilot and Force-sensitive and was trained by Luke when she was young.
"Star Wars: Episode 8" should shed more light on who she really is when the film hits cinemas Dec. 15.
