STAR TREK

[viper37]

So. 4 1/2 vulcans.

So changing species is just that easy.... And this is never done again?

And vulcan behaviours being genetic rather than something learned?... That flies against canon.

changing species, they keep doing it in all trek series, but it's usually cosmetic surgery.
This is an evolution of the old trick.

Why did La'an go Romulan though. All this time are Romulans not just ancient vulcans but actually vulcan augments?

I'm guessing all the characters behavior is a reference to your previous point, genetic vs learned logic.
Without proper training, logic becomes flawed.  That's why La'an becomes so militaristic, so Romulan, in a way.  She has trouble integrating Vulcan logic with her own emotions.

Flawed episode, like so many this year.

I've read they struggled with the strike this year, had trouble adjusting to the pace.
