During the infamous Ajan Kloss meeting, I wondered if maybe when Rey hears the word “Exegol,” the other voices could get a bit muffled and she could hear Luke’s voice quietly saying the same word before going back to look at his notes. Since the wayfinder hunt is finishing what Luke began (in more ways than one), it might be nice to bring more attention to him, and this would be an easy way simce Rey reacts to it.

If you want to get really radical, maybe Rey could hear Luke’s voice a few times throughout the movie. Though perhaps that would hurt the impact when Luke finally arrives in person and when Rey contacts the Jedi on Exegol.
