It sounds like Luke Skywalker’s possible rejection of Rey in Star Wars: The Last Jedi will push the scavenger towards forming an alliance with her one-time nemesis, Kylo Ren.
This is similar to the position Rey finds herself in Last Jedi, as she’s left lost and alone when Luke abandons her training.
Ridley admitted the Resistance doesn’t mean that much to Rey, and Kylo Ren doesn’t appear too concerned with advancing the agenda of the First Order.
That “unexpected” place is Kylo Ren, who sees a kindred spirit in Rey.
