Edit: if we want to split Palpatine and Pryde’s conversation from later in the movie, and do a bit of sentence-mixing, we could do it like this:
Spy recording on Ajan Kloss:
Palpatine: “Send the ships to a world they know. Let it burn. The Final Order begins.”
Pryde: “Yes, my lord.”This gives context to Poe’s line, “He calls it the Final Order. In 16 hours, attacks on all free worlds begin.”
Is a little short, but if you combine it with the dialogue from the broadcast it might work better with the reaction shots from the resistance base.
“At last the work of generations is complete, Skywalker is dead. The Republic, Destroyed. The day of victory is at hand. Send the ships to a world they know, let it burn.
The Final order begins.”
“Yes my lord”
