Command officer 2  

This female command division officer was treating the wounded crewmembers in sickbay when Tom Paris acted as the protagonist in The Doctor's holonovel. ()

Marseilles' dates  

These two crewmembers entered sickbay to receive their medical check-ups while B'Elanna Torres acted as the protagonist in the holonovel. When the first woman entered, Torres was sent to engineering by Marseilles but was sent back by Torrey. When she entered the dark sickbay, she found Marseilles with this crewmember on the biobed.

The second woman then entered sickbay for her medical examination and Torres realized that Marseilles used these examinations for dates with female crewmembers. ()

Operations officer 4

Altered version 
The narrator, now based on Paris, gave a tongue-in-cheek introduction based on the original.
The protagonist was the chief medical officer's medical assistant.
The CMO is egotistical, unethical, and obnoxious. He has a bad comb-over and is more concerned with his extracurricular activities, like golfing, than with his patients. Later, Paris mused that The Doctor was not the doctor shown in the holonovel, insisting that this doctor "had more hair", in reference to the superficial differences between The Doctor's characters and their Voyager counterparts.
Two of Three, similar to Three of Eight, was part of a set of triplets, which also included the unseen One of Three and a third sister, unnamed. She was quite demure and submissive in her attitude.
