I think the version in the workprint feels too much like –
“What’s the message?”
“It’s two lines from Palpatine.”But it doesn’t imply that was the whole message. Taking the dialogue in the scene as a whole, it implies that they received some kind of First Order briefing message, of which the Palpatine recording was only part of. I’d say it’s much better than the theatrical version, where the message was basically “Palpatine’s back and he’s got an army of Death Stars, so you’d better hurry!”
Yes I imagine the implication is they get some sort of intel package that includes a recording of Palpatine as proof, as well as the stuff Poe exposition dumps after, but in movie language the recording is the answer to Rey’s question. And it feels like it’s only a couple of lines.
The crowd hearing Palps in any way is definitely better than “somehow palpytone retoned” but I argue the recording goes by a bit too fast, it’s over by the time you realize what’s going on.
