It is revealed that Ren is the son of Han and Leia, and was once one of Luke's Jedi pupils. He was drawn to the dark side of the Force by the First Order's Supreme Leader Snoke. He then helped to destroy his uncle Luke's new Jedi Academy. However, Ren still feels the pull of the light side of the Force and seeks the strength to overcome this weakness from his grandfather Darth Vader, whose burnt helmet is in Ren's possession. Arriving at Maz Kanata's castle on Takodana, Ren captures Rey, who he senses has seen the map. While interrogating her with the Force, he realizes that she is strong with the Force herself, though unaware of it. Rey finds herself able to resist his powers and experience Ren's emotions, and confronts him over his fear that he will never be as powerful as his grandfather. She later uses the "Jedi mind trick" to compel her stormtrooper guard to let her escape. Han arrives at the First Order's battle station, Starkiller Base, as part of the Resistance's plan to destroy it.
