I just realised something with the new Dagger translation. Babu Frik expressed understanding after Sith-3P0 recites the translation, then when the gang arrive on Kef Bir / Endor and meet Jannah, she says they got a message from Babu Frik saying they were coming. This is what prompts them to trust each other at their initial meeting.
But we’re changing it so the translation doesn’t say “go to this planet,” it explains how the Dagger works. Rey doesn’t reveal that they’re going to Endor until they’re on the Falcon. So how does Babu Frik know to send a message to Endor that Jannah receives?
