When Mandi Bierly spoke to Julie Plec yesterday about the midseason finale, she got some extra details on what fans can expect when Bonnie’s mom, Abby Bennett (Persia White), makes her debut in episode 12, which Plec said she’s currently writing. “In our show, we’ve met a series of Bennett witches. Obviously it is something that seems to have been passed down from generation to generation,” she says. “The lineage of these witches, with Grams and Emily Bennett, has been very important to our show, and Bonnie’s heritage has been very important to the mythology. So it’s about time that we ask ourselves who her mother is, and what her mother might be capable of as a witch or not a witch, and where the hell she is.” Also juicy? We will find out exactly what’s been keeping Mama away from Mystic Falls and her daughter.
