For Cisco, he must learn to not fear but embrace his power.
Iris and the Wests must deal with Francines imminent death.
This Reverse-Flash is the Eobard Thawne who kills Barrys mother and comes back in time and masquerades Harrison Wells.

And its understandable why.
How does he figure out how to do so?
By scaring the living hell out of Cisco.
He wires the goggles to induce a similar effect and allow him to control the length of his vibes.
Are you telling me I can see the future, Cisco asks.
Thats exactly what Im telling you, Harry deadpans in response.
Those goggles are getting named immediately, Cisco says, solidifying the need for a Harry-CiscoThe Office-style spin-off.
Barry is called back from the brink of murdering him and instead brings him back to S.T.A.R.
Labs, where Cisco takes a victory lap.
But Cisco stops riding so high when his nosebleeds at the lab turn into full-on seizures.
That means freeing the Reverse-Flash and sending him home.
NEXT: Saying goodbye to love and loved ones
The thought initially haunts Barry.
Barry accepts his fate and suits up to combine his speed with Thawnes and propel him back home.
He learns of S.T.A.R.
Labs, of all the people Barry cares for, and of Barry.
Barry also had to learn to let go in his non-speeding hours as well.
Patty hoped they could be cordial with each other, but at work Barry is distant from her.
She wants him to admit who he is.
She wants to hear the truth.
Part of her very much wants to stay rather than leave for school.
And there is part of Barry that wants her to, as well.
Feigning an armed attack on the train, she incites Barry to rush to her aid.
He lets down his protective shield to let Patty see and hear Barry in the costume.
Barry and Patty are learning to let go, learning to say goodbye.
Francine is on the verge of death, and its time for the family to say their final farewells.
Joe does so offscreen, giving Iris the key moment of forgiveness before her mothers imminent passing.
Theres still Wally who has to say goodbye, but hes refusing to do so.
He wants to stay out on the road racing instead of facing what reality has in store.
Accepting his mothers death proves too difficult, but Iris talks some sense into the boy.
He has the rare opportunity to actually spend a knowing final moment with Francine.
Eventually he comes around and asks Iris to help him say goodbye.
To help him let go.
The only solution is to find Zoom, but Caitlin refuses to accept that at first.
She thinks of finding his Earth-1 doppelganger, and replacing Jays sick cells with Earth-1 Jays healthy ones.
But that proves impossible, as Jay explains to her.
Jays counterpart was adopted and eventually given the name Hunter Zolomon by his new family.
So Caitlin lets go, just as Jay has, of all other possibilities.
