This season The Flash has been primarily concerned with the sudden arrival of Nora, Barry and Iris' daughter from the future, but Caitlin Snow has been dealing with family problems of her own. In the Nov. 20 episode, appropriately titled "The Icicle Cometh," Caitlin will finally meet her father, the Arrowverse's version of the comic book villain Icicle.
Icicle is a code name shared by The Flash foes Joar Mahkent and his son Cameron. Whereas Joar required a cold gun, Cameron was a metahuman with natural cryokinetic powers. Father and son previously showed up in the animated Young Justice.
On The Flash, Cameron was name-dropped earlier this season as the man who "confirmed" the death of Caitlin's father, only to turn out to be a false identity. Caitlin's been slowly trying to figure out why her father faked her death, and a recent episode confirmed that someone is spying on her.
CAITLIN LEARNS SOMETHING NEW ABOUT HER FATHER — Caitlin (Danielle Panabaker), Barry (Grant Gustin) and Cisco (Carlos Valdes) learn something new about Caitlin’s father (guest star Kyle Secor). Meanwhile, Iris (Candice Patton) and Sherloque (Tom Cavanagh) follow a clue about Cicada (Chris Klein).
Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanaugh, Jesse L. Martin, Danielle Nicolet, Hartley Sawyer and Jessica Parker Kennedy.
