If Machete had a real fever and hallucinated an angel who explained germ theory to him, do you think he would take that well? Would he retain any of that?

He'd be absolutely horrified in the dream and Concerned upon waking up, and I think that uneasiness would probably last for a day or two. But realistically he'd know it was a dream and eventually rationality would win. Besides, if he tried to talk about such an incomprehensible, outlandish concept with anyone, surely they would think he had finally lost it.
