When I started watching the series, I had this doubt. As the three seasons went by, I came to the conclusion that she was simply a woman.
There was a character in the Fallout series, Dane, and I completely missed the fact that they were non-binary. I thought they were more of a tomboy character, but no—the character is non-binary, and the actor is a trans man, if I’m not mistaken.
I want to know if I was the only one who thought Erica might be the same case.
It’s weird to say because I usually try not to make assumptions about people, but sometimes I feel rude for not noticing these things sooner.


Weird just search José Tyler that’s the character she is based on
Nope, she’s clearly a completely different character. Tyler would have been on the crew during “The cage”, which takes place before the events of Discovery s2. According to his Memory Alpha entry:
Also, Tyler is listed on Memory Alpha as navigator, Ortegas as senior helmsman. Sure, it’s a fan wiki, but Trekkies are sticklers for these things.
