Caitlin’s inner Killer Frost is unleashed after she uses her powers to save Barry; on a rampage. Killer Frost goes looking for Dr. Alchemy, kidnaps Julian and battles both the Flash and Vibe. Joe and H.R. have an honest discussion.

The Flash is interesting as it gets Caitlin to go full Killer Frost and begin to become the villain we knew she’d become. There’s some good and some bad with this.

The good is, Caitlin as a bad guy is bad ass. It’s some solid acting and it’s a character I’ve liked as far as a villain for some time. The bad is she was a solid female lead who was also a scientist. The show has a bad habit of spotlighting their female characters in a negative way. Iris has gotten better but she was originally the love interest Barry couldn’t have and Jesse was a damsel when she started on the show. Caitlin was the one character who was competent and a scientist. Now she’s a slightly loony bad guy…

That was the big chunk of the episode until we got to the end, where one of my predictions totally was revealed as the identity of Dr. Alchemy is exposed. It wasn’t a hard one to figure out at all, but it’s nice to see it confirmed at this point.

The episode also shakes things up for Barry who has to make a decision about Caitlin’s actions and if she should face justice. It’s a plot we’ve seen in comics a bunch of times, but cool to see it be brought over to the series.

The negative of the show is a certain someone getting their powers in a flash and zipping away. It’s something we expected to see, but out of everything that happens in the episode, it feels like too much packed in. And that’s the big thing about the episode. Some is really good and is given the proper amount of attention while other plot points are just too quick and aren’t focused on enough.

There’s a lot to unpack from this episode and for the series to explore for the rest of the season so in that it’s pretty good.
