Well, you like the saber toss, but I don’t, so our editing motivations are clearly at odds here. But I think it makes sense for Luke to be conflicted. He’s never been one to just give up hope. I’m trying to convey a sense that Luke began to regret his decision after the years went by, but he had already crashed his only means of escape into the ocean. When Rey comes bearing his old saber, Luke realizes that he finally has a chance to return and redeem himself, but he’s still not convinced whether that’s a good idea.
