Arlene Wilcox is a citizen of Salem, and a friend of the gang.

Physical appearance

Arlene is a teenaged Caucasian female with dusty brown hair. She wears a blue turtleneck sweater, a light blue jacket, blue pants, and black shoes.


The thought of her long dead ancestor rising from the grave scared her very much, which is understandable. As she had no knowledge of her twin sister, she was shocked to learn of her existence but did not seem angry at her.

Season three

She was suspected of being possessed by her look-a-like ancestor, who was accused of being a witch by the people of her town, but she was being framed by her twin sister, with the help of the graveyard caretaker Gar Mooney.



  • According to Velma, it's impossible for Arlene to be a Gemini since she was born in October.
    • Geminis are born in the late spring and early summer, between May 21st and June 20th. Since Arlene was born in October, that would make her either a Libra (September 23rd to October 22nd) or a Scorpio (October 23rd to November 21st).
    • "Gemini" was used simply as a code for "twin" and it does not mean Arlene's birth sign. This is confirmed by Arlene's birthday.
