Personally I prefer the way it plays out originally, Cassian’s main objective is to “authenticate the story and then if possible find [Galen Erso]”. They believe he is critical to the development of this weapon, which plays into the orders to kill him. And on that note, I wouldn’t want to lose Draven’s reaction to “Jedah Destroyed”, it gives his orders more motivation (killing Galen, commanding a direct assault on Eadu). He feels “a decision needed to be made”.
Those cut lines are also where Cassian autheticates the story, “Weapon Confirmed. Jedah Destroyed”. He then asks if he proceeds with the secondary objective after learning Galen is on Eadu. Jynn’s “speech” is not meant to rally them to go to Eadu, she’s telling them her father is not the evil imperial they believe, it has a purpose as it is what makes Cassian hesitate on following his orders. The Rebels don’t know that Galen is working against the Empire, and neither does Cassian, since the message was destroyed on Jedah, he has to trust Jynn’s word.
I think if this change was merged with the “secret mission” change, it would muddle the motivations of everyone. The progression in the story makes more sense if “finding Galen” is given some importance from the beggining.
Ah, those are good points and it would make it “murky” about Cassian’s “secret” orders. What would be the point of those orders if the earlier scene at the briefing room was just about finding the pilot. I also get what you mean with Jynn’s role and it does make some sense. There would be a disconnect with the “kill orders” if there was nothing officially or unofficially talked about finding Galen.
SO I would be ok with not going that route now for the sake of the “secret kill orders” since that change in itself I think adds plenty of benefits.
