So that whole new line is all the officer? I was kind of confused at first because the way 3PO raises his hand makes it seem like he got an idea or is trying to get someone’s attention. Did anyone interpret his movement that way? It seems like I’m the original deleted scene the movement means nothing, so I guess it’s okay.

As far as the actual line for the officer (bold is what should match his mouth movements):

“And General, if the advance team is… destroyed… nobody will be able to help us.”
OR
…nobody can get past that shield.”

I was kind of confused at first by what the purpose of this line was. But I kind of see it as the officer saying that whether or not we get help, none of it will matter if the advance team can lower the shield.

I also wanted to suggest a pacing for the first line based off the officer’s mouth movements:

“General, the Senate has just voted. They’re mobilizing the fleet. Launching within an hour.”

You could make that last sentence longer if there is more time, but I tried to truncate it just in case. It also kind of flows with the officer being in a rush to pass the info to Leia.

EDIT: Rewatching it, I’m kind of worried people will be confused why Leia is being pessimistic despite finally getting what she wanted. I think if the officer said “within an hour” rather than “within the hour”, it might help make it clearer that it’s gonna take too much time. Nitpicky, but I don’t know if the fleet launching in an hour or less justifies Leia being so confident in their doom. I mean, how much faster can they be, Leia? “Within an hour” makes it seem like it’s gonna take them a whole hour to launch.
