"The Flash" season 3 recently cast actress Susan Walters to play the role of Caitline Snow's (Danielle Panabaker) mom Dr. Carla Tannhauser.
According to Entertainment Weekly, Dr. Tannhauser is described as a world class biomedical engineer and CEO of a major research company.
Even though she and Caitlin are both smart, this does not necessarily mean that they get along really well. In fact, Dr. Tannahauser and her daughter have had ongoing problems when it comes to their relationship.
Caitlin always saw her mom as distant and cold, but Dr. Tannhauser always regarded her daughter as rebellious and ungrateful.
"Dr. Carla Tannhauser is 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," the publication noted.
Meanwhile, Caitlin first talked about her mom during one episode from "The Flash" season 2. During that time, she shared a scene with her Earth-2 doppelganger Killer Frost.
Caitlin verbalized the issues she's had with her mom after finding out that Killer Frost also have the same problems with her own mother.
The casting of "The Vampire Diaries" and "Teen Wolf" alum actress is expected to bring more exciting storylines for Caitlin.
Some fans are already speculating on that possibility of Caitlin and Carla having a major confrontation with each other in the upcoming episodes.
Other fans also believe that it's possible for Caitlin and Carla to set aside their differences and help each other out for the common good.
Now that Barry Allen aka The Flash (Grant Gustin) altered the timeline, it's possible too that Caitlin and Carla will be reunited during the time when the former wasn't still involved in Barry's life.
In other news, "The Flash" season 3 is also expected to introduce a slew of new characters that are related to some of the major characters in the series.
As of late, the parents of Barry are already expected to return in the Flashpoint storyline.
"The Flash" season 3 will premiere on The CW on Oct. 4 at 8 p.m. ET.
