In true Flash form, the episode begins with Barry confronting Savitar and telling him he knows who he really is. And then a time jump to 16 hours earlier happens and you watch as it all begins to unravel itself before your eyes. Continued from last episode, the team sets out to find Tracy Brand, the scientist who developed the tech to trap Savitar, and see if can help them out in any way in the present. When they find her, they discover that she’s begun burning all of her work as she’s just failed her doctorate. However, already knowing the future, the team does what they can to convince her to keep going. HR even takes a liking to her. But their efforts are interrupted as Killer Frost makes an appearance and tries to kill Tracy. Barry manages to save her but gets hit in the process. Cisco confronts Killer Frost but hesitates and is then hurled over a counter by Frost’s powers. Barry acts quickly and uses his powers combined with a blow torch to thwart off Caitlin for the time being.
Not long after agreeing to help the team, Tracy runs off. After quickly researching her, HR figures out where to find her. Tracking her down to a park with a statue of Galileo, he finally talks her into finally working with the team. While one couple seems to be blossoming, another looks like it’s about to fall apart as Joe and Cecile go over their struggles. Joe breaks things off with her over fear that she’s going to get hurt if he learns about his “complicated” life. But as she leaves his house she’s captured by Killer Frost and taken hostage in exchange for Tracy. The team shows up with a plan, but Caitlin seems to be in sync as to what their plan is. Almost as if she planned it herself. But she says that she learned everything from Savitar. A battle ensues and Caitlin manages to freeze Barry, but Cisco overcomes his worries and is able to defeat her. He then takes a blood sample to work on a cure for her.
While this is nothing compared to what happening to The Flash in the comics, this is still quite the reveal. As far as other big reveals, the twist concerning the identity of Zoom still remains the top reveal of the series. That shouldn’t take away from this moment though. The reason why it’s probably second to that moment with Zoom is because fans of the show have gotten smarter. By the time the show had gone on it’s three week hiatus, theories about Barry being Savitar had already begun to surface on the internet. By tonight’s episode, it was all but confirmed.
So who is this version of Barry? Is it really Barry from the future because it doesn’t entirely make sense. What went wrong that would cause Barry to turn into a serial killer? And where did he get that scar? Answers! Fans need answers! Maybe this is Barry from one of the endless, possible futures. This Barry could have experienced the worst of everything and is here to take out all of his aggression on this Barry. Time is such a confusing thing.
It’s time to talk about that cure for Caitlin. By now, you should know that Killer Frost is one of those iconic villains from the DC universe. The character is so popular and so well known that she was given her own one-shot in DC’s Rebirth Universe as well as made a member of The Justice League America after the Suicide Squad had a little battle against them. Getting Caitlin Snow back would be wonderful. She’s developed into a strong female lead and is an important part of team flash. But happens to that iconic villain, Killer Frost? Maybe it’s a struggle that not only will the writers have to deal with but the fans as well. Either way, Danielle Panabaker is great as Caitlin Snow and she’s great as Killer Frost. On a final note, does having a cure for Caitlin mean a cure for all meta-humans? Or just her?
The Flash airs Tuesdays on The CW at 8 PM EST. Check out a preview for next week’s all-new episode.
