I have a theory about where the bad blood in the Chase family comes from. I can't really back up this theory but I want to see what you think of it.

Randolph, Frederick, and their sister were told the viking legends by their parents as bedtime stories. Randolph grew up believing the stories were true, and dreamed of traveling the nine realms having adventures. Randolph's brother and sister either didn't believe in the stories, or stopped believing when they grew up. Randolph never stopped believing and dedicated his adult life to trying to prove the myths were real and maybe even open a door to Asgard. When his quest was discovered he was ridiculed and thrown out of Harvard. Meanwhile both of Randolph's siblings caught the eye of an immortal and had demigod children.
