| | McCoy : | "The chain of command is often a noose." |  |  | to Spock | 
 | 
| | Lenore : | "And this ship. All this power. Surging and throbbing, yet under control. Are you like that, captain?" |  |  | to Kirk; Oh my! | 
 | 
| 
   | McCoy : | "Do you play God? Carry his head through the corridors in triumph? That won't bring back the dead, Jim." |  | Kirk : | "No. But they may rest easier." |  | 
| | Karidian : | "Blood thins. The body fails. One is finally grateful for a failing memory." |  |  | to Kirk |

   | Lenore : | "You are like your ship. Powerful, and not human. There is no mercy in you." |  | Kirk : | "If he is Kodos, then I've shown him more mercy than he deserves." |  | 
| | Kirk : | "We've armed man with tools. Striving for greatness continues." |  |  | to Kodos; in response to the latter's claim that modern life has dehumanized Mankind |

   | Lenore : | "All the ghosts are dead. I've buried them. There's no more blood on your hands!" |  | Kodos : | "Oh my child, my child! You've left me nothing!" |  |
