That sounds like a very extreme sensitivity to another food or maybe the timing was just coincidental and it was something they ate earlier. My and most people's alpha gal response is usually delayed by hours, supposedly due to food having to digest and break down food components into alpha-gal.

Another explanation is allergies and panic attacks also go hand in hand from what I've heard. Panic attacks cause breathing problems and can easily be confused with anaphylaxis or make real anaphylaxis even more terrifying than it already is. Feeling fear that a threat is ever present when you have any food allergy is real, but manageable.
