The Falcon crew determines BB-8’s map is incomplete. Han explains that Luke attempted to rebuild the Jedi Order but exiled himself when an apprentice turned to the dark side, destroyed the temple, and slaughtered the other apprentices.
On Takodana they meet with cantina owner Maz Kanata, who offers assistance getting BB-8 to the Resistance.

Meanwhile, Rey arrives on Ahch-To with Chewbacca and R2-D2 aboard the Millennium Falcon to recruit Luke Skywalker to the Resistance. Disillusioned by his failure to train Kylo as a Jedi, and under self-imposed exile from the Force, Luke refuses to help and believes the Jedi should go extinct. Unbeknownst to Luke, Rey and Kylo communicate through the Force, puzzling the two enemies. As Rey and Kylo learn about each other, both have visions of themselves as future partners.
R2-D2 persuades Luke to train Rey. After Kylo tells Rey what happened between him and Luke that caused him to choose the dark side, Luke confesses that he momentarily contemplated killing Kylo upon sensing that Supreme Leader Snoke was corrupting him, causing Kylo to destroy Luke’s new Jedi Order in retaliation.
