Polly Parker, sister of Fiona Parker. When her mother passed away of cancer in early 2011, Polly was left her car, though she really wanted her mother's vase, causing a great deal of dispute between she and her Fiona. However, her mother's car hadn't been serviced in some time, and was leaking dangerous carbon monoxide, poisoning Polly and resulting in her becoming very sick. This sickness almost went unnoticed, as it was at first attributed to the heat wave, but was eventually treated by Drs. Zoe Hart and Brick Breeland.
