Dr. Caitlin Snow’s (Danielle Panabaker) father will finally make his Flash debut in the program’s fifth season.
Entertainment Weekly reports Veronica Mars veteran Kyle Secor will play Dr. Thomas Snow, the missing parental figure in Caitlin’s life — and the person potentially responsible for her metahuman powers. Described as “an extremely intelligent geneticist who has been MIA for decades,” Snow returns to make up for lost time. He is hiding a big secret, of course, and it may relate back to Killer Frost.
Late in the fourth season, Caitlin discovered her powers and the Killer Frost persona predate the accelerator explosion at S.T.A.R. Labs which gave rise to Barry’s (Grant Gustin) powers and the wave of metahumans in Central City. In the upcoming season, Caitlin will turn to both of her parents for some insight into this seemingly impossible truth.
Of course, keen-eyed observes will remember Caitlin had no powers prior to Barry’s creation of the Flashpoint timeline. But it seems a more fundamental change occurred in the prime timeline upon his return from Flashpoint.
The Flash returns October 9th on The CW.
