Fans of The Flash are about to learn a lot more about Caitlin Snow in season three.
Entertainment Weekly reports that Vampire Diaries alum Susan Walters has been cast as Caitlin’s mother, Dr. Carla Tannhauser, in season three of The Flash.
Tannhauser is described as “a world class biomedical engineer and CEO of a major research company. But while Caitlin may have inherited her mother’s formidable scientific mind, the two have long had a difficult relationship, with Caitlin finding her mother cold and withholding, and Carla regarding her daughter as rebellious and ungrateful.”
Caitlin’s mother was first mentioned during The Flash‘s trip to Earth-2, where Caitlin’s doppleganger Killer Frost had not so nice things to say about their mother.
The Flash season three premieres Tuesday, Oct. 4 at 8/7c on The CW.
