Here’s another one for you (I don’t know what’s up with the story editing this season).
Spock doesn’t go for the grav plating controls because the script demands that he be later placed in jeopardy in the ion pod and have a dramatic complication that has to be solved by his mind meld.
But of course it strikes one as a bit odd in-universe why he didn’t try for the grav plating controls when Vulcans are hardier - obviously nobody would have known he’d be needed later for the ion pod.
But, if he and Una had swapped, and Spock was the one with the broken foot, not only would have made more sense initially, but also actually lucky. Una may have made it out unscathed, or at least less injured, because she’s shown an ability to cure lethal radiation exposure in the past due to her Illyrian heritage (SNW: “Ghosts of Illyria”). Every story beat would be the same except for the mind meld bits.
But then you sacrifice the mind meld scene for story logic.
Not all Ilyrians have the same augmentations, is the impression I get. So no, it’s not a given, but unless Spock knows specifically what kinds of augmentations Una has - and I don’t see that being a given either - the logical (pardon the expression) person all eyes turn to in the face of a high-gravity problem would be him. Even if it’s a, “Commander, let me - I was raised on a high-gravity planet,” remark met by a “No, I’m XO and I’m Illyrian,” retort, that would have been settled.
And as someone on reddit pointed out, even if Spock hadn’t been the one to go in, he could have melded with anyone who had been injured in the pod. Nothing in the story need have changed at all except the person involved.
