Agreed. I had forgotten about the foreshadowing- but I remember that now. For ghostwriters, they did a good job with that. Clearly AMM was still quite involved at that point. I know she herself wrote Stacey’s Emergency as I recall.
I definitely feel they should have taken time to grow a buildup to an actual emergency in previous episodes.
That being said, speaking as someone who has seen my share of 30s, 47 doesn’t seem fainting low to me, but as I said, I tend to hypoglycemia over hyperglycemia. As my endocrinologist said to me, your body adjusts to its own norms.
