So Sonya Gomez, who played a role in two TNG episodes later goes on to play a very prominent role in the book series Star Trek: Corps of Engineers. But on the covers of more than one or two of the omnibus covers, she's (I'm pretty sure it's supposed to be herm anyways) shown with a metal/cybernetic arm.
Now either I'm confusing her with a different character, I'm not recalling her character correctly from "Q Who" and "Samaratin Snare", or someone decided to draw her with a robotic arm for some reason that doesn't exist.
From where I am in the series, I have not read a single passage even references this.
Now if something happens later in the series that warrants this, just mention you as much, but I don't want to hear any spoilers, please and thanks. Otherwise, just show me the error of my ways.
