Katherine Vaughn - Mary's Grandmother

This is Katherine Vaughn, Mary's grandmother and Sheriff Nick's mom. Like all mother-in-laws, she loves Alison like she were her own and spoils Mary rotten. This kick-ass granny also likes to take Jane and Jessie out to bars, metal concerts, you name it. She also makes sure that Jane and the girls don't go beerless either. She loves her grandchild, son, Jane, Jessie, and her daughter-in-law to death. If you mess with her and her family, she'll make you regret the day you were ever born. Kathy may look harmless, but she is a parkour practitioner, veteran street fighter, and a black belt. So she knows how to kick ass and take names!
