With the latest season of The Flash ending in some troubling time-travel, fans are eager to see what Grant Gustin’s Barry Allen has done to the timeline when the show returns to the CW this Fall. However, according to the show’s Executive Producer Andrew Kreisberg, fans should also be looking excited about Caitlin Snow’s upcoming storylines.

In an interview with Collider, Andrew Kreisberg spoke about Danielle Panabaker doubling up as both Caitlin Snow and Killer Frost in the most recent season of The Flash. And, more importantly, Kreisberg teased that Caitlin’s mom may be making an appearance in Season 3.

When asked where Caitlin might go in the third season, Kreisberg teased fans by saying that, “We haven’t met Caitlin’s mother yet. We got a little talk between the two women, which will probably play out in Season 3.”

While Caitlin’s mom has never made an appearance on The Flash, she was mentioned in the show when Caitlin and Killer Frost had a less-than-stellar conversation describing their estranged mother. Fans know little else about Caitlin’s family or her past aside from these characters’ terse discussion, but Killer Frost did let slip that she had a brother on her Earth. With The Flash’s timeline promising to bend after its recent season finale, it’s not out of the question that Caitlin might discover a long-lost brother pretty soon.

Andrew Kreisberg went on to applaud Danielle Panabaker for her acting and insisted that the Killer Frost’s introduction was only possible because of the actress’ hard work. When asked about the sorts of technical challenges which plagued the villain’s scenes, actor Tom Cavanagh (Harry Wells) chimed in and said that, “She put in a 17-hour day in two cells. The table read was great because there were these volleys back and forth, where the voice would change. It was Danielle talking to Danielle, but it was tremendous to watch. And then, you put her in that outfit. There’s always a lot of stuff going on, but she was phenomenal with it. She was loving every minute. It was really, really impressive to watch.”

With the possible addition of Caitlin’s mom to The Flash’s cast, Danielle Panabaker might soon be given more room to explore her character’s hidden past and uncover where Caitlin is heading in an increasingly unstable Central City.
