She is very talkative. In her only appearance she assisted Whit in judging for the first Whit's End science fair. It should be noted that she's the only person during Paul Herlinger's tenure as Whit that frustrated Whit to the point he actually yelled at her.
Evelyn is John Whittaker's cousin. She also has a husband, though his name is not given.
