Barry, Harry, and Cisco travel to Earth-2 to rescue Jesse from Zoom but encounter Killer Frost, Deathstorm and Reverb (Caitlin, Ronnie and Cisco's evil Earth-2 doppelgangers, respectively). Despite Harrison's warning, Barry and Cisco do indeed get emotionally caught up and emotionally invested in seeing themselves and others they've known living alternate lives, which threatens their mission. Back on Earth-1, Jay takes on Barry's responsibility of defending Central City when a quake-inducing meta-human called Geomancer comes looking for a rumble with The Flash.

Did You Know?


When Barry picks up the phone to call his mom, it shows a list of names to call. The names are: Dad, Mom & Dad, Eddie, Bruce, Hal, and Diana. With this info we know that Eddie Thawne is alive on this earth and Batman(Bruce), Green Lantern(Hal), and Diana (Wonder Women) exist on earth 2 as well. We don't know if they exist on earth 1 yet.

At Jitterbugs, everybody's Meta-Human Warning App goes off prior to the arrival of Deathstorm and Killer Frost. It was proven at the police station that Earth-1 Barry (a meta-human) can set off these apps as well, yet he does not at Jitterbugs. See more »


Jay Garrick: Caitlin, I like the way you look at me with warmth and pride, and I'm not... I'm not worthy of those.
Caitlin Snow: Yes, you are.
Jay Garrick: No. I did a terrible thing, Caitlin. When my world's Particle Accelerator went off, I became a speedster. I became the fastest man alive, only... only it wasn't enough for me. I wasn't... I wasn't fast enough, so I figured with my scientific background I could increase my powers. I did.
Caitlin Snow: So you've taken Velocity-6 before?
Jay Garrick: Yes, but there were some... unforeseen side effects.
Caitlin Snow: This is...

Jam-Packed Fun
9 February 2016 | by ThomasDrufkeSee all my reviews

Much like last week's Arrow episode, tonight's Flash has so much material and so much to digest that i'm not even sure where to start. I think some may take issue with just how much the episode tried to cram in, but I think the highly entertaining factor of this episode trumps any of those critiques, especially for those who love easter eggs.

The team finally got a chance to travel to Earth-2 in what is basically this show's version of the 'What if?' story line. The easter eggs began right away as we saw Arrow, Flash, and Supergirl in continuous images while Barry, Cisco, and Harry went through the breach. You have to think the shows knew about the crossover with Supergirl months ago and just decided to announce it before we all saw her in the portal. Supergirl as a show is pretty weak, but I think it's pretty cool that she is at least in the same galaxy as Flash and Arrow. Leaving the door open to crossovers is always a good idea.

After Cisco and Barry got their selfies at the Earth-2 Star Labs it was time to get down to business as they heard Mayor Snart is moving the curfew up after more Zoom attacks and even Earth-2 Barry talking about the issue. Yep, apparently a member of the Snart family is Mayor of Central City. Yikes. This wasn't the first time a villain was doing good things in this earth as none other than Deadshot himself, Floyd Lawton, is a cop working under Detective *Iris* West. It's always fun seeing Michael Rowe reprise his role, I only wish he would somehow come back on Arrow. Hope it's not another situation in which they can't use any of the characters from the upcoming Suicide Squad movie, but it probably is. Also, how did Barry know who he was?

Back to Flash. As much as I don't want to ever see Iris and Barry get together, I enjoyed the new dynamic of having them married on Earth- 2. Also, Joe West as a singer who despises Barry? That's awesome. It was really fun to watch Grant Gustin play a different side to Barry but then seeing him break down after hearing his mom's voice again was devastating. Of course, the call was overshadowed by the fact that the telephone had Bruce, Diana, and Hal on speed dial. Oh my god. Sure, these are all just teases and easter eggs for hardcore fans, but man, there was almost too many to handle tonight. I'm pretty sure Jonah Hex was also seen in the beginning as well. My oh my.

Aside from all the references, there was a solid story behind it, and I think it will work even better as a two part episode including the next episode. While Barry was trying to find a way to figure out how to beat Zoom on earth-2, Jay covered for him back on earth-1 taking the velocity-7 and temporarily being The Flash. It's worth noting how much Jay and Wally have been talking about not being 'Fast enough', just like Zoom's motives. For now, the writers are just trying to get your head spinning about who Zoom is, but don't be surprised if either of them turn out to have their doppelgangers be Zoom all along.

Killer Frost and Deathstorm were the 'villains' of the week if you don't count the stupid inclusion of Geomancer. As I don't think we will get Caitlin's version of Killer Frost on earth-1 anytime soon, I had a lot of fun watching Danielle Panabaker take on a new role this week. It was even cooler seeing Reverb AKA earth-2 Cisco absolutely show them who's really in charge, only to be murdered by Zoom shortly after. What an entrance huh?

In all seriousness, this may not have been the best episode of Flash, but it was probably the most fun I've had with this show since its inception. It was also probably the most refreshing for all the actors and writers involved as they got to explore a completely different side to their characters. Here's hoping for an earth-2 trip to Star City? No matter, next week will be fun as well as we hopefully get a full on Zoom episode and figure out who the heck the guy locked up across from Barry was.

+Everyone got to play a different side to themselves
