The Flash EP Describes Caitlin Snow's Relationship With Her Mom

In the second season of The Flash, when Zoom (a.k.a. Hunter Zolomon) abducted Dr. Caitlin Snow from Earth-1 and brought her to his lair, she eventually met her Earth-2 doppelgänger, who had already transformed into the villainous Killer Frost and was being kept in a cell. Though not having a lot in common at that time, they both described their mothers as being frigid narcissists. And while Caitlin wasn't sure why her mother was "as cold as ice," Killer Frost revealed that her mother's icy personality resulted from the death of her son (Frost's brother), Charlie.

We'll finally meet Caitlin's mother, Dr. Tannhauser (guest star Susan Walters), in an upcoming episode (titled "Monster") that will air at the very beginning of next month. Because her mother is a renowned biomedical researcher, Caitlin will seek out her help as she continues to transform into Killer Frost.

In the latest installment of EW's Spoiler Room, Executive Producer Todd Helbing teased the frosty mother-daughter relationship. "You've heard snippets throughout the show so far of how her mom is pretty cold," Helbing said. "When you meet her, you'll understand exactly what Caitlin has been talking about and exactly how their dynamic works. You can see how that's had a long-term effect on Caitlin."


EARTH-2 WELLS AND JESSE RETURN TO CENTRAL CITY — Barry (Grant Gustin) and Team Flash are thrilled to reunite with Earth-2 Wells (Tom Cavanagh) and Jesse (guest star Violett Beane). Wells confides to Barry and Caitlin (Danielle Panabaker) that Jesse has all the powers of a speedster and has been saving people on his Earth. He is concerned about her safety and wants them to talk her out of using her powers. Meanwhile, Magenta, (guest star Joey King) a new meta who can control metal, terrorizes the city.

The Flash's visual effects maven Armen V. Kevorkian directed the episode, which was written by Judalina Neira and David Kob.
