Of all the harebrained schemes Barry has come up with, this has got to be the most harebrained yet. Go back in time to consult with the Reverse Flash on how to go faster. Seriously, Barry, what were you thinking? I had forgotten just how menacing Eobard Thawne was, even while in the guise of affable Harrison Wells. Harry-2, while gruff and kind of a dick, was never actually menacing. At least we got to see Eddie again.
Still no mention of the Supergirl trip, but this episode sets us up for that: Barry tries out Thawne’s formula, complete with tachyon device, and jumps universes while trying to go faster. He also apparently time traveled inadvertently, or maybe the universes just that out of phase.
So is Pied Piper supposed to be a good guy now? Did Cisco still kick his ass back in the past?
