The theory stating that Rey would go from Luke Skywalker’s pupil to hand in hand with Kylo Ren and the dark side has been floating around for months, and Star Wars hasn’t been shy with hints of Rey’s possible turn. The latest spot for The Last Jedi, might show off the strongest supporting evidence yet.
