Dumpster, thanks for sharing this learning experience. She was stressed but nothing in her behavior indicated to me that she was truly panicked. As such, I don't think there's much more you could have done (once she committed to being in the water) other than maintaining physical contact from the time she thumbed the dive. That might have reduced her stress a little or it might not, it just depends.
Diving with an insta-buddy whom I said I would "watch out for" I wouldn't have taken the speargun but I know you dive mostly with it and it's second nature. Personal preference on that one but I would have chosen differently. It certainly didn't seem to impact your behavior much so it's probably a wash either way.
All in all I thought the whole thing was handled reasonably well until the end when she took off.
I've been very lucky having been insta-buddied on most of my dives and never having had to deal with any of this kind of stuff. My closest was a called dive before we ever dropped below the surface.
