| Decker :  | "The commander is responsible for the lives of his crew, and for their deaths. Well, I should have died with mine."  |   | recording his last words |

| McCoy :  | "To blazes with regulations! You can't let him take command when you know he's wrong."  |   | to Spock; on Commodore Decker |

| Kirk :  | "Gentlemen, I suggest you beam me aboard."  |   | to Spock; perfectly calm as death approaches |  
  | 
   | Kirk :  | "He gave his life in an attempt to save others. Not the worst way to go."  |  
   | Spock :  | "Indeed, Captain. I presume your log will show Commodore Decker died in the line of duty."  |

| Kirk :  | "Ironic, isn't it? Way back in the 20th century, the H-Bomb was the ultimate weapon, their doomsday machine. We used something like it to destroy another doomsday machine. Probably the first time such a weapon has ever been used for constructive purposes."  |   | to Spock |
