in "", ren tried to prove himself to snoke after being defeated by rey by leading the attack on the resistance fleet, although he hesitated to kill his mother. he also formed a special force connection with rey, through which he revealed to her how luke had tried to kill him on the night that he turned to the dark side, leading rey to come to confront ren, believing that there is still good in him. ren brought rey before snoke, who ordered him to kill her, but he instead killed snoke and then worked with rey to defeat his praetorian guards. ren offered rey to rule the galaxy alongside him and detach herself from the past, claiming that her parents were nobodies, but after she refused, they fought over possession of luke's lightsaber, which rey had been using, leading to it being destroyed and rey escaping. ren then pinned snoke's death on rey and declared himself as the new supreme leader of the first order, before leading an attack on the remains of the resistance on crait. after luke showed up to confront ren and give the resistance enough time to escape, ren fought him, only to discover him to be a force projection. as ren screamed in anger, luke died peacefully on ahch-to, having used all his remaining energy to project himself on crait, and the remains of the resistance escaped aboard the "millennium falcon".
