I wonder if we could have Leia begin the little briefing at the start of the movie. We could get rid of the Emperor’s Fortnight speech we added, and come into the scene with something like this:
Leia: Emperor Palpatine has returned from the dead, and laid claim to his former Empire. The First Order was a diversion.
Cut to that one shot of Leia looking worried.
Poe: “His followers have been building…” and the scene plays out.
Not at all sure of it, but tossing out the idea.
