Great notes, as always.
In addition to the already-cited references, the Beagle could additionally be a sly reference to Archer’s pal Porthos.
Interestingly, Jolene Blalock is credited simply as “Jolene”. EDIT: Mike McMahan says this was at her request. https://bsky.app/profile/mikemcmahan.bsky.social/post/3ld3v4usznc2i
Our T’Pol also had some indirect experience with the concept of katra transference when Archer briefly carried Surak’s katra.
I agree it’s overused for the average episode of Trek, but if we accept that they’re doing a Section 31 movie, what’s the point of a low-stakes feature film (even a streaming film), especially one centered around Section 31?
Also worth noting that the article describes it as “Big stakes emotionally, big stakes for the characters in our story”, so the “stakes” are referring at least in part to character stakes, not necessarily universe-ending stakes. (Though I admit in practice it will probably be both.)
