The Flash Season 2: 7 Ups And 4 Downs Of 'Invincible'

6. Doppelgangers

Wait, aren’t Reverb and Killer Frost both dead? Killed at the evil hands of Zoom, right? Oh hold on, these are their doppelgangers!

Seeing Earth-1’s Cisco and Caitlin dressing up as their evil Earth-2 counterparts was a nice tough here, and it certainly lent itself well to the use of Laurel Lance as Black Siren. It was also great to see the S.T.A.R. Labs crew thinking a little outside the box.

Sure, logic gets lost a little when one thinks about just how they managed to get identical Reverb and Killer Frost outfits at the drop of a hat – maybe there’s a local fancy dress store that stocks them? – but it was a whole lot of fun to see Cisco and Caitlin pretend to be their evil doppelgangers.

Even more fun was the inevitable giveaway, which then saw an irked Black Siren target the duo.
