This episode killed me when I listened to it, and reading through this thread killed me again. I'm not sure if this is the right place to post this but I found something that seemed amusingly similar.
So, I googled Vulcans from Star Trek and the first thing that came up was a fandom wiki link, which I clicked. I saw that the term "emotion" had it's own page and thought back to this episode of the F Plus. Of course, I wanted to know what emotions are in the Star Trek universe (apparently 'An emotion, or emotional state, is a physical state which can either be a response to an external stimuli or the product of a memory. The state can either be positive or negative. In sentient species, the emotion can trigger a feeling. Emotions can be observed through facial expressions and body language. (TNG: "Shades of Gray", "Data's Day").' I've never seen Star Trek Next Generation, but I sure am glad that it devoted a few episodes to covering what emotions are, or we might not know what exactly that term means in the Star Trek universe.
The reason I posted here, though, is that it also has a list of emotional states. Some of which have their own pages. The pages for individual emotions all follow the same format: a few sentences to describe the emotion, then a series of disjointed paragraphs describing episodes in Star Trek in which that emotion was present. Most of the pages just seem to refer to other emotions in their descriptions. For example, the page for frustration refers to annoyance, which itself has a page that refers to irritation and anger, each of which have their own pages which refers to annoyance. Others have circular definitions, for example: "Protectiveness was an emotion characterized by being protective of another individual."
Anger and rage are included separately in the list of emotions, but both redirect to the page on anger (images for this page: Nog_angry.jpg and Khan!!!.jpg)
Optimism is listed as an emotion, but pessimism is not. Similarly, "motherhood" is listed as an emotion, but fatherhood is not. After imagining someone saying that she was feeling motherhood today and giggling to myself like the idiot that I am, I clicked that on that link and found that it actually went to the "parent" article, subsection "mother." It turns out that the terms mother and mommy have been known since the original series, but fans were forced to wait until Star Trek Next Generation to learn what the french call their "maternal parents." I wonder when they'll get around to the other languages.
Shock is listed as an emotion. It redirects to a page that describes shock as a medical condition, but then lists what seems to be every example in Star Trek in which someone has either been emotionally shocked or physically gone into shock.
Rejection is listed as an emotion, but links to a page dedicated to transplant rejection.
Anyways, link if anyone here is confused about what emotions are in Star Trek and is just dying to know https://memory-alpha.fandom.com/wiki/Emotion
Again, sorry if this is the wrong place to post it.
