Continue the scene from TROS where Rey bemoans that the wayfinder got destroyed, where Luke reveals that he used his powers as a Force Ghost to shield Kylo’s wayfinder from harm when Rey set fire to his fighter. He explains that this is why he was in the right place at the right time to catch the saber she threw at him.
I absolutely love this one as a Bad Edit Idea because it’s the exact sort of thing I could see somebody very earnestly trying to implement unironically.
