Whitecoats

The term "whitecoats" is used to describe the scientists who worked at the School because they wore long, white lab coats. Jeb was a whitecoat until he brought the flock to Colorado, and returned to his job two years later

Max often refers to the School's employees as "whitecoats" rather than "scientists". She doesn't refer to Jeb as either, and merely calls him by his name.
