Ahch-To’s Two Suns
After exerting so much effort in projecting a Force version of himself to confront Kylo Ren on Crait, Luke peacefully succumbs to death during the weepy end of The Last Jedi. Back on Ahch-To, he sits on a rock and watches the two suns set for the night as he fades away into nothing, as all Jedi masters do upon death.
It’s a beautiful scene but it gets even more poetic when you realize that Luke’s last sight calls back to where his story began many years before. As a boy, Luke grew up looking at two suns every day on Tatooine, as seen in A New Hope. It’s a nice touch for director Rian Johnson that brings the character’s journey full circle.
Meanwhile, there’s another callback to Luke’s life on Tatooine in Star Wars: The Last Jedi. When Rey is following him while he goes about his daily routine earlier in the movie, Luke milks a cow-like animal native to the planet. The animal’s milk happens to be tinted green, a homage to the blue Bantha milk that was so popular on his first adoptive homeworld.
