While that wasn’t my original intention for removing that conversation, I think you’re right that is does create some interesting ambiguity to how much Jyn can trust Cassian. It makes the audience wonder if Cassian is hiding something from her.

My original reason for removing that conversation was because the whole nature of their mission changed. They’re no longer looking for Jyn’s father from the get-go, they’re just trying to find the Imperial pilot, so by necessity I had to cut that conversation between Draven and Cassian.

This does make me want to go back and finish that edit.
