Bernie is Ben's best friend, and an emo who looks just like him as they dress the same, even though Bernie is a girl. She has long black hair, black cargo shorts and pale skin. She is a member of the Waitrose group. Ben describes her as sometimes saying things she shouldn't and getting him into fights. Despite being a noncombatant, Bernie, along with Ben are capable mechanics. She helped to create a gate door barricade, an outdoor brazier made from a washing machine barrel and speaking tubes inside of the Waitrose supermarket. Bernie and Ben team up with Shadowman during The End to rig a volley of car bombs to attack the Fear during the final battle. They used the explosives inside of stadiums such as Wembley, based on the information Ed gave to Shadowman about the explosion in The Oval cricket stadium.
