It absolutely is ergot poisoning lol. The tell was the funky smelling rye bread. That was the biggest culprit. I bet the blonde saint just doesn't ever eat it at all and that's why she never gets it, or she just avoids the weird smelling/tasting ones.
I mean she is a noble so her workers probably pick out the best portion to serve their masters and everyone else makes due with the leftovers/ the contaminated portion.
You know how there's a theory that the hysteria/hallucinations of the girls involved in the Salem Witch Trials was caused by a type of mold in their grains? I wonder if that's what's going on here?
