Re: Why did Dax remove her spots?
I mean, I've never known everyone at my workplaces, yet I knew everyone's face and generally knew when new people were brought in, so I wouldn't get suspicious that there was someone hanging around who shouldn't be. But here are four people who shouldn't be there, and just because they're dressed in the right uniform, no one questions it.
In the novelization, Kirk actually wonders about Sisko after meeting him, remarking to Spock that he didn't carry himself like a lieutenant (Sisko's faux rank while wearing TOS gear). Given Kirk's penchant for being thorough, one wonders if he went back through the duty roster or personnel files to look for someone who wasn't there.
