Scary thing about psychopaths, they function perfectly logically with the context of their delusion. I worked ambulances in my youth and met my share of them. One was a lady who believed that the rock she was holding was a dinosaur egg that spoke to her and told her that some colors were out to get her, but green was safe. When we got her to the locked ward, she started going nuts on us until I pointed out that the nurse had a green pen and reminded her that green meant she was safe, whereupon she immediately stopped fighting.
The nurse, who’d been fighting with the woman while simultaneously yelling at me to butt out, was still looking stunned as I danced away.
That nurse was a real piece of work. She ‘secured’ our patient, and twenty minutes later, having completed the paperwork and changed sheets on the gurney, we pulled out of the parking lot and saw our former patient sitting on a bus bench out front. We debated letting them know their patient had escaped, looked at each other, realized we’d be helping the nurse, and simulaneously said “Nahhh”. “Mrs. Dino Egg” waved as we drove by.
