The scene in the lounge was nearly cut in half as well and in it he also professes his friendship for Kirk, saying, .."if a had a best friend you be that as well..."
I'm glad they cut that much out...it would have seemed very contrived.
Yes, because to find out any new information about kirk's relationships with other Starfleet members would be bad.
Without seeing it filmed, it's hard to judge, but I agree with
The Old Mixer, as it does seem a bit contrived to suddenly have someone we've never seen or heard about profess that Kirk's the closest thing to a best friend that he has.
It teeters on the line between learning new information about Kirk's relationships with other Starfleet members and something shoe-horned into the plot for convenience.
Perhaps if we'd seen Morrow in
The Motion Picture greeting Kirk and questioning his decision to take the demotion to Captain. Or if Morrow was in
The Wrath of Khan, talking to Kirk before Kirk and crew left for the
Enterprise inspection, then the scene you described would seem less contrived.
Or if the scene in
The Search for Spock scene was a little less sounding like a "bro-mance" forced into the script. If Morrow instead said something along the lines of, "Jim, I've enjoyed our chats over the years, you've been a good friend and I'd hate to see you throw all of that away," it would have sounded more natural.
Again, without seeing it filmed, it's hard to judge, as it could have been a nice addition, allowing us to see Kirk's circle of friends extend beyond his senior officers. It would also serve as a way to give us insight into Kirk's years as an Admiral, where, presumably, due to Spock going off to Vulcan, McCoy retiring, and the others overseeing the refit, as well as Kirk's own duties as an admiral, he wouldn't have been able to see the
Enterprise crew that often.
