The one with the planet killing machine, and crazy Commodore Decker.
Decker made a decision to beam his crew to a planet "for safety", only to find the planet destroyed and the USS Constellation spared. He is a man very similar to Kirk, so we can identify with that, and the fact that Kirk may have done the same. The guilt ridden Matt Decker we see, distraught, and in shock, and is presumably what Kirk might become if he ever made a similar error of judgement. Only Decker realised that the doomsday machine had chopped up planets in the system, and that his crew were sent to the next planet in line. And couldn't he give Spock more detail on the planet killers weapon range, it might have helped a bit. Sounds like that would have given McCoy enough to certify him as unfit to command to me
Scotty loses his Scottish accent for one brief line of dialogue about the detonation trigger he has wired for the Constellation ("and thirty seconds later. . . poof!")
