The results of time travel take center stage. Taking place directly after last week's episode, Barry goes full on Groundhog Day after reaching a peak speed attempting to stop Mark Mardon's tidal wave, Barry gets transported back to before the morgue investigation. This of course throws him for a loop, but also works out for the better. In the day that never happened... Harrison Wells reveals himself as Eobard Thawne to Cisco before swiftly killing him, Captain Singh gets violently zapped by Mark Mardon, and Joe faces some serious peril while Mardon continues his quest for revenge. All bad things reset, some of the good... like Barry finally kissing Iris and subsequently revealing his identity as The Flash.
If time is like a still lake, even the slightest ripple of change equalizes, Wells warns Barry that diverting from what he originally did would have Butterfly Effect like repercussions, and jumping the gun on apprehending Mardon does just that... with Cold and Heatwave coming back to Central City. Team Fire and Ice join with Leonard's younger sister Lisa... DC's Golden Glider. After kidnapping Cisco and violently coercing him to build a brand new cold and heat gun, Cisco builds Lisa a golden gun... literally turning whatever she shoots into solid gold... or a gold like substance.
Harrison's lie begins to unravel this week, his aggressive chides toward Barry playing with the timeline and a mysterious disappearance of a certain reporter begin the eventual no-holds-barred battle royale between Flash and Zoom!
Much of the episode's charm was bringing back Cold and Heatwave, introducing Glider to the team further builds the eventual Rogues of Central City. I've been a bit let down by the characterization of Cold from his first appearance, primarily how he doesn't shy away from indiscriminate killing. After the events of Flash vs. Cold this time around, it looks like Cold's penchant for the thrill of the job will begin shaping this character. That's a good thing, what made the Rogues such interesting villains is their motivation. They aren't world conquerers like Darkseid or Ra's al Ghul... and neither are they indiscriminate mad killers like The Joker. All that matters is the job, that and grabbing a beer after successfully scoring a major payload.
Leading up to the finale... the season has run at break-neck speeds... and it doesn't look to be slowing down.
