"[EVELYN EVERNEVER] Female, Late Teens – Early 20’s to play Late Teens, Open Ethnicity. Otherworldly, seemingly omnipresent, and a bit odd. She’s eager to befriend Betty, and is surprisingly insightful for her age, but may be hiding dark secrets about herself. (While not required, a possible direction for the role is a girl who is physically reminiscent of “Betty”.) MAJOR RECURRING GUEST STAR."
Fans of the original Archie comics will remember Evelyn from the Little Archie comics. She has appeared in Little Ambrose's issue and in many issues of Betty & Veronica Spectacular.
According to That Hashtag Show, Evelyn was actually Archie's kidnapper when he goes missing and is even Archie's first kiss.
