I’d say that she still isn’t convinced to fight for the Rebellion in the Hologram scene. She is actually more interested in finding and rescuing her father. It is only after his death (strangely, at the hands of the Rebellion) that she decides to get the plans. I don’t think she ever really aligns with the Rebellion, more accurate to say that they both have the same objective in the end.
That sounds more like what I remember.
See, I was right without knowing why.
