Karen is a typical nerdy teenage girl, enjoying book series such as Twilight or Harry Potter, as well as photography. She is known for being a rule-follower and a serious student, getting good grades, caring about her college applications and working as a librarian's assistant in an unpaid internship. She seems to dislike troublemakers, and doesn't hesitate to report any rule violations to teachers or higher-ups. Unlike most of the cast, she is very naive and clueless, being unfamiliar with sexual slang such as "skeeted on," and believes her so-called friends when they falsely tell her it means to be complimented. Karen is also pretty sensitive and insecure, and easily manipulated. She suffers from bulimia, whenever someone point it out it can trigger her to relapse, and is seen crying or disturbed on multiple occasions. Despite her vulnerabilities, she seems well-intentioned and friendly, assisting Nicole with learning how to use a camera despite her attitude on one occasion. It is implied she is lonely and longing for friends or popularity. She arguably is the most normal and least problematic person in the cast as she doesn't have any truly negative traits or flaws. She's also highly allergic to dogs
