Snoke's mind link between Ren and Rey leads them to the Island. Luke and Snoke fight to an incredible stalemate, each one showing their true mastery of the force. Ren and Rey face off again. The Millenium Falcon is destroyed, Chewie dies in the battle, and Rey and Luke barely escape in his X-Wing after Rey is housed out by a powered up Kylo Ren who was feigning vulnerability to help the mind link find their location. This is about the same time as Rey leaves the island in TLJ. Final battle ensues later. Luke kills Snoke, but Kylo kills Luke and Leia, and Rey and The Resistance barely escape.
