Heather is a teenager friend of Vanessa Doofenshmirtz.
Heather went to Vanessa's girl movie night with Dana, Lacie, Birgitte and Candace before the pharmacist breakout. When the breakout happened, she was among the people transformed, and also one of the few who believed they would survive by doing the typical zombie movie stuff (she suggested she would walk backwards to a dimly lit room).
When the pharmacists got in the room and transformed Lacie, she stayed together in a group with Birgitte and Dana, who were transformed not soon after.
Heather has brown hair, green eyes and wears a black jacket, red shirt, black fingerless gloves and dark blue pants with black shoes.
