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.

Barry flashes about in his doppelganger's street clothes yet his speed friction doesn't set these pedestrian threads on fire (not even producing a little smoldering). See more »


Barry Allen: Caitlin.
Killer Frost: I haven't heard that name in a long time.
Barry Allen: That is your name, isn't it? Your real name? Please, look... I know you. Don't do this.
Killer Frost: If you knew me at all, you would know that I hate the name Caitlin. I'm Killer Frost.

It's a pretty good concept. Showing how things are different in Earth-2, what the people in Earth-1 could have been, the road not traveled and all that. The ending does a good job of raising the stakes.

All this is overshadowed by the sheer irritation at watching Barry and Cisco. They react to every little difference between the Earths with shock that scrambles their brains for a good thirty to sixty seconds. Wells didn't go around gawking at everything that was different from his Earth; he just accepted it and moved on because he had a mission to focus on. Barry and Cisco also have a mission, a really important one, but keep getting distracted by trivialities.

After a while, you want to scream in their faces, "Get over it and move on with the plot!"
