I've been going back and forth with that final scene. It might just mean Luke going "oh shyt you found me, don't make me do this
"
But then again, Rey is parentless and was left on a desert planet without knowing she's strong in the Force, and Luke was very emotional when he saw her. Maybe he left her after failing to train Ben? And if Luke really didn't want to be found, why the hell would he leave a map with his whereabouts?
R2D2 an a$$hole though, you have BB8 trying to wake your ass up to go find Luke and you wait for complete chaos and destruction to ensue before finally revealing you have the rest of the map
Can't wait for ep. VIII
I need answers
