She was an activist and rambler from Dembley, known for campaigning against issues such as fracking and climate change.
She was portrayed by Debbie Chazen.
Along with the rest of her rambling group, Jessica went rambling across an old public footpath along the back of Charles Fraith's property. The group were met by Charles and his assistant Gustav, who insisted they stopped walking across Charles' land as his crops had long ago grown over any path. Charles was happy to comprise, allowing the group to walk around the edge of his land instead, but Jessica remained adamant that she wanted to walk across the original path.
The next morning, Jessica went rambling by herself across the footpath on Charles' land but was interrupted by Deborah Camden, who fatally hit her in the back of the head with a shovel. (The Walkers of Dembley)
Jessica was feisty and could be pushy, not one to be afraid of making a stand. She was often manipulative to ensure she got her way and was known to use sex as a weapon. (The Walkers of Dembley)
Jessica had mid-length, red hair.
- The character is mistakenly listed as 'Jessica Tarnick' in the television episode credits.
