Star Trek

Exactly. Not an alternate universe, just a branch timeline from the point the Enterprise-C was suppose to be destroyed.

So the altered timeline had been departing from the Prime timeline in meaningful ways for about 30 years at the point of the alternate events of Yesterday’s Enterprise. Before Tasha and her sister were born. Their lives could have played out very similarly, or they could have been completely different. That’s why I wanted to hear what other people thought.

The whole out of universe production explanation is good. Like how some things in the Original Series went past warp 10 because the showrunners were still figuring out what Warp was and how to represent it.

I think that even though it was believed from a production standpoint that she would be the same woman, just not killed by Armus, she still gave a slightly altered performance. I don’t know how much of that was her just getting back into the character, or being told to act ‘darker and more serious,’ or if she deliberately chose to set this timeline’s Yar apart. Crosby’s definitely someone who can act with that nuance because Sela is portrayed as a unique character and not simply a Romulan Tasha.
