So who are you?
Hey,
we got your alert. Where's...
That's not Caitlin.
Uh... [chuckles]
What's--what's happening here?
Actually, it's kind of a long and very confusing story.
One which we are happy to share.
First, please meet-- - You can call me Snow.
Wait, as in, like, the third Snow sister?
Barry, do you remember the time that you found out
Caitlin was trying to bring back Frost,
and you destroyed her lab?
I didn't have a choice.
The point is,
Caitlin never gave up.
She kept on working with me.
Together, we built a machine to reactivate Frost's mind
in Caitlin's body.
Only... - Something went wrong.
But in place of Caitlin...
I came out instead.
Well, if you're not Caitlin or Frost,
who are you?
Honestly, I don't know.
I wanna find out who I am just as much as the rest of you do.
Snow here is a total blank slate
with zero memories.
So I've been doing my best to bring her up to speed.
Mark, what happened to Caitlin?
[sighs]
Where is she?
Caitlin's dead, Barry.
- What? - That's impossible.
I--I--I know what you must be thinking,
but I have a plan to bring Caitlin back.

Now the CRC was supposed to unzip neural DNA from Caitlin.
That way, we could isolate Frost's brain patterns
inside of her-- - Download into another
new body later on.
Only a power fluctuation
caused the process to malfunction,
and so if
Team Flash could provide me with a stable energy source,
we could reverse the process
and just bring Caitlin back.
So now you want our help?
For Caitlin's sake,
yeah.
It's Caitlin. We have to try.
Yeah, I'm sold.

to Caitlin when she was a child.

at Tannhauser Labs. Now, it's a lot, but...

Is this really true?

In his original experiment,
Thomas Snow tried to create a Caitlin 2.0,
one that would be immune to ALS,
but instead, he created a daughter
with two mixed consciousnesses,
and when he tried to reverse it,
he found out
the process would kill one of them.
That's why Thomas never built his own CRC,
because he loved both Caitlin and Frost.
He couldn't bear to lose either of them.
Just like us.

We're gonna have to choose

Mark, we're all pretty clear

Okay.
I vote to bring back Frost.
Mark's right.
Caitlin chose for us.
This was her plan, so choosing Frost honors her.
Right, Chuck?
Chuck?
Um,

but no.
Allegra, look, when Deathstorm brought my dad back,
it taught me one thing:
that resurrecting the dead
is unnatural.

I'd choose Caitlin,

it's what makes the most sense to me.
Mm,

you're with Chester, right?
That way, your super-hubby can tip the scales to Caitlin.
