Danielle Panabaker Talks Killer Frost, Kevin Smith, and More in Talk Show Appearance

During an interview on the latest episode of The Lowdown With Diana Madison, The Flash actress Danielle Panabaker talked about a wide-ranging variety of topics related to the show's third season.

Among those topics? Will Caitlin sing in the forthcoming musical crossover between The Flash and Supergirl; will she appear in the four-show Invasion! super-crossover; and what was it like trying to wrangle that much talent for one story?

You can see her responses in the video above, as well as a little bit of teasing about Killer Frost. That's not only her metahuman identity, but the name of he season's seventh episode, which will be directed by geek icon Kevin Smith.

Panabaker said it was great to have Smith back on set, and that since she hadn't had much in the way of interaction with him when he directed "The Runaway Dinosaur" last year, she was glad to get to work with him more (one would assume a lot more, with that title) this time around.

In tonight's episode of The Flash, Caitlin -- who has been showing some signs that she may have powers herself -- gets time to talk to Jesse Quick about the experience, and what she would do if -- hypothetically -- she got metahuman abilities.

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 airs on The CW every Tuesday at 8 p.m. ET/PT.
