Kyle Secor As Caitlin's MIA Father On 'The Flash'

Entertainment Weekly has learned that Kyle Secor will recur during Season 5 of The Flash as Caitlin Snow’s absentee father, Dr. Thomas Snow. Dr. Snow is an extremely intelligent geneticist who has been MIA for decades. Upon returning to Central City, he will try his best to make up for lost time with Caitlin (Danielle Panabaker). But what Caitlin doesn’t know is that Thomas is hiding a big secret.

In season 5, Caitlin will first turn to her mother, Dr. Carla Tannhauser (Susan Walters, who guest-starred in season 3), for some insight into her current predicament.

“[Carla] is the one she goes to first for answers,” executive producer Todd Helbing tells sources. “You’re going to learn about what role her mother played in all of this, and there is that mysterious premonition that Cecile had at the end of last year about Thomas. So you’re going to learn about exactly who he is and how he plays into the season and Caitlin and Killer Frost, and really just that whole mystery about where she comes from and how she was created is explained.”
