Sounds like Hanna will be getting a visit from "Grandma Reg" real soon. In her interview with Huffington Post, actress Betty Buckley revealed that her character, Regina - Hanna's grandmother - will be guesting on Pretty Little Liars during the winter mid-season premiere for season 3.
"I'm also in the first episode of the new season of "Pretty Little Liars," which starts airing in January. It's my second appearance on the show…my character's name is Regina, and I call her Grandma Reg. She's an Oklahoma rancher who was a glamour girl in her day; she's really outspoken and very hilarious. She's kind of over the top and very protective of Hannah.
I hope they'll keep bringing Regina back. Those girls are great, I love them, I love the whole team -- they're really terrific people."
Will Grandma Regina's protective nature with Hanna (Ashley Benson) come out in ways relating to 'A' or maybe her parents?
