Also still no reason given why Carol Marcus needed to change her clothes in a shuttle craft while speaking with Kirk.
I felt the reason was clear enough in the film; she was changing into a flight suit and time was of the essence. Maybe not the best reason, but I understood what the reason was supposed to be.
*Keenser is identified as a Roylan, but I couldn't remember if this information was given in the previous novelization or revealed here. Also unsure if it matches the name given in his origin story in the comic series either.
The name of the Roylan species was first established in Star Trek Ongoing
issue 14, which tells Keenser's origins in flashback.
