As for RFM...it's a favourite of mine...do we know what the extra lines between Kirk and Rayna were about?
I read the script ages ago and from what I can recall it was
a lot of dialogue where Kirk and Rayna bond while talking about her varied talents and interests. It would have helped the audience understand Kirk's becoming enamored with her so quickly IMO. At least it did for me when I read it. Maybe other people who have seen the script would remember better.
