Now of course it's again possible to think of complicated explanations for that ("She wanted to gauge his first reaction to the Galorndon Core Incident to get an indication of how trustworthy he was"), etc, etc, but still ...Hrm ... that actually sounds somewhat plausible, except for the fact that I don't see Beverly doing it.
The scene does play out as if Crusher laid a little trap there, as she immediately points out that knowledge of the incident would be surprising for a man of Setal's position.
She of course would be well versed, having also patched up LaForge after her son rescued the two men. So she might simply find "Setal's" nonhostile tone of voice downright insulting and quip back, only then jumping to Starfleet Intel mode.
Perhaps. Then again.I would find it weird if Beverly didn't have some multi-species knowledge.
The same applies to McCoy, really - but it's not surprising that an obvious need would not easily translate into a capacity. Heck, since it does seem implausible for a single person to be capable of covering all of
Homo sapiens, let alone two or more species, it should be pointed out that only the EMH has ever demonstrated true multispecies skills, that is, the ability to dive in without first diving into a pile of books.
No doubt Crusher could bring herself up to speed by consulting a somewhat less bodily version of an expert program, and Jarok could mistake that for skill. On the other hand, practical skill, rather than abstract knowledge, seems to be what "Setal" is commenting on, from the receiving end.
I mean, Talok has a romulan head ridge, so he's probably genetically romulan.
Or then the ridges are also found on Vulcan. Which is what I mean about this whole ambiguity thing: we see and hear of attributes that
aren't uniquely identified as either Vulcan or Romulan, save for the logic religion thing which is at least heavily implied not to be a Romulan attribute. Things like ridges and melds and pon farr and T-negative blood are wholly up in the air. Which sort of leaves "Romulan" up there as well.
Naturally, we're supposed to tell Romulans apart by their ridges, that is, the ridges exist for that purpose. But we are also expected to accept and recognize Romulans without ridges. So the out-universe intent does not really translate into any sort of in-universe rules.
