I didn’t realize this page was for RotJR, I wondered which thread I was subscribed to that was debating love stories.
As for the lightsaber, of course Luke eventually picked it back up. He threw it away to show he wasn’t going to use it to kill his father. It’s still his lightsaber that he should have a spiritual attachment to (see TFA’s Family Saber).
Are people saying that it should be removed from the celebration? Can’t it just be implied he picked it back up while he was slowly dragging Vader’s body down to a shuttle bay?
