The edit goes something like this:
Transition from Tarkin scene (Aka security breach, Galen erso is at Eadu)
goes to Jynn sitting staring at the wall on U wing. The dialogue between Chirrut & Baze about “Tell me … the whole city” has a line between them talking where you hear Cassian say “Set a course to Yavin 4”
So you see that the scene has changed that they are heading back to Yavin 4 after witnessing the weapon’s fire power. Now most of the dialogue in the rest of the scene has Jynn talking about the message and how to destroy the death star. So she recommends going to Eadu to get her father to explain it to the rebels. Then it cuts to Yavin 4 establishing shot, and shortens the scene with Draven saying “Proceed … my orders still stand, yada yada gotta kill Galen Erso.”
Establishing shot of U wing in hyperspace and cassian then tells K2 to set a course to Eadu.
What I like about this change, is it get’s Jynn to be more proactive now, especially after hearing that message. Since the original scene was:
“we are going to Eadu”
“where my father is?”
“yes”
“His message talks about a weakness in the death star, we can destroy it!”
“Where is it?”
“Well … it’s destroyed! but everyone is behind me/believe me, let’s go get him! Rally Call!!”
( … we are already going there. She was … kinda motiving people to do what they were already seemingly going to do.)
So it kinda gives actual purpose to Jynn’s speech and motivation, to actually “rally” the troops to do something based on a moment of defeat or uncertainty of what to do next. She is helping to move the plot, not just being there for the ride. In a sense.
