Spoilers below in the form of an upcoming Flash episode's official synopsis, along with details about this week's episode.
The Flash is known for amping up the craziness every step of the way - there are a lot of steps taken in Barry Allen's daily commutes - and it sounds like the post-Flashpoint timeline is about to get climactic, just in time for Kevin Smith to return to the show. The director's upcoming installment will be a lot less serene than his emotionally-driven episode last season, and it all has to do with the emerging forces inside of one Caitlin Snow. Grab a warm blanket and check out the description for "Killer Frost."
Caitlin (Danielle Panabaker) uses her powers to save Barry (Grant Gustin) but as her mother predicted, the effort unleashes her inner Killer Frost. Killer Frost goes on a rampage looking for Dr. Alchemy, kidnapping Julian (Tom Felton) and battling both The Flash and Vibe (Carlos Valdes). Meanwhile, Joe (Jesse L. Martin) and H.R. (Tom Cavanagh) have a heart to heart talk.
Action! Excitement! Hearts juxtaposed with hearts! In the last episode of The Flash, Caitlin took a trip to meet her mommy dearest, a driven-by-work scientist played by Susan Walters. What the cooler-than-a-cucumber Team Flash member learned from her mom is something she'd have learned eventually anyway: the more she uses those Killer Frost powers, the less she remains Caitlin Snow. And of course it's going to be an effort to save Barry from something that will be the straw that pushed the frozen camel over, thus shattering it and breaking its back.
I do like the fact that unlike Earth-2's Killer Frost, who was a minion of Zoom, this burgeoning version of the villain doesn't seem to have an allegiance with anything or anyone. She's going after Doctor Alchemy, so she obviously finds a reason to hold a grudge against the big bad. She's kidnapping Julian, which should bring an interesting connection, since Tom Felton has mostly been kept to screentime with Grant Gustin and Jesse L. Martin. And then she's getting into fights with both Flash and Vibe, which is totally bonkers.
It's one thing when Flash is fighting Caitlin from another dimension, but another entirely when Barry and Cisco are having to incapacitate one of their closest friends. Not that they haven't done it before, but Killer Frost won't have any remorse for the things she's doing to Flash and Vibe. I kinda hope she gets some good licks in before justice prevails and Barry does whatever he needs to rid Caitlin of her Frosty ways.
Kevin Smith is directing from a script written by Andrew Kreisberg and Brooke Roberts (from a story by Judalina Neira), and I kind of can't wait to see what happens when H.R. and Joe hit it off. That's not the most likely pairing on here, but maybe they'll bond over crooning and live music. Had Smith written the episode, it would have been Star Wars and weed.
