They could have just had Pelia push a secret button to reveal her stash of alien tech, and that probably would have been fine. Instead they show her as this woman who’s very smart and obviously immortal but otherwise…just a person living through history, which is so much better. Imagining the 250 years between the present and when she’s one of the most famous engineers in the fleet is fun.

It's not just fun--but it speaks to a different demographic than most shows speak to.

It's telling older women that it's not too late to change and grow and learn. Here she is, obviously having already lived a long life--but then we learn she hasn't ALWAYS been an engineer from the start. She did not begin as someone obviously fascinated by science.

She realized later in life. And then she was able to SUCCESSFULLY pursue her career and become an expert. Just because she wasn't a child prodigy didn't mean she couldn't learn and grow. There's SO many stories focusing on people who have things 100% right immediately out of the gate. Top grades in school, top performance at work, accolades, reccomendations from the time they were teens.

But this story is of an ordinary eccentric retail worker...who goes back to hit the books and succeeds with her change.

This lesson will go over 75% people's heads...but in true Star Trek fashion, even if it elludes many, it'll hit home with the demographic it's meant to talk to. Older women who feel like they're too old to change. That they shouldn't even try. It's talking to THEM like so many other characters in Star Trek talk to other overlooked people.

And that makes this detail--one out of many in this excellent episode--top Star Trek.
