At least you say that there is a character arc.
I mean sure. She changes in the movie. But it happens over the course of one scene and I think that she was an terribly written character.
I haven’t seen the movie*, but I don’t think you are right about this being all in one scene.
*In the past 8 months or so.
I’d love to hear a response to how what I said is not correct. She does not give a crap about the rebellion. She sees hologram in the very next scene. After this she is set on finding the death star plans and stopping the completion of the superweapon.
