The macaw is Jerry, a supernatural entity with the ability to mind control others who come into physical contact with it, Sam is a human cultist wearing a blue robe that worships Jerry like he is his god. If you say anything bad about Jerry Samuel will get very very angry and try to attack you if deemed necessary. Jerry cannot speak, only squawk, and Jerry acts like a normal parrot, preening itself, chirping, etc. Samuel has surprisingly very good manners and is very polite to non-sinners.
