Savitar appeared to me

- If the answers that we need
to stop Savitar

and save you are in the future,

You trapped Savitar
in the Speed Force.

Just tell me how you did it.

That's something.

So what do we do?

Just--just hear me out.

I know you're--you're worried

I don't think your abilities
have ever come from a place

They come from somewhere good.

They come from love.

And if you can find it in you

then I really think
we can save her.

We gotta figure out

- Killer Frost? Savitar?

You know some people
with really scary names.

- Eh, but is it too much?

All of us here
would understand.

Personally, I just--
I just wanna make sure

that, you know,
you don't get hurt.

As a matter of fact,
I was thinking--

- I was thinking too.
- Yeah?

- About Savitar.
- Mm-hmm?

- The way the light reflects
off his suit,

it's unlike any other metallic
compound I have ever seen.

- Hmm, you and I were thinking
about different things.

What do you think it is?

- In Fermi liquid theory,
any sort of non-Fermi liquid

is called "strange metal."
- Mm-hmm.

- It's a theoretical compound
capable of dispersing heat

at high temperatures.
I think Savitar travels so fast

that he needs that suit
to neutralize the charge

he builds up around him.

- Huh.
Interesting.

So without the suit,
he's just a dude

with a bad case
of static cling.

- Yeah.
So if we could build a device

capable of harnessing
that power,

theoretically, we could use
his own velocity against him.

- And trap him
in the Speed Force.

Tracy, you are indeed a genius.

- I'm getting there.
- Well, yes, you are.

[gasps] That means you're
gonna stay and help us.

Is that what that means?

- If I do, does that mean
the future's changing?

- I think it means
mine certainly has.

[light knocking]

- Hey.
- Hey.

- Thanks for seeing me.
Come on in.

So how are you doing?

- Joe, I'm fine.
I just--you know,

I wish that you would've told me
what was going on with you.

Although I...obviously
have some idea now.

- It was my fault that you got
caught up in all this.

I'm so sorry, Cecile.

- Joe, me too.
Look, I--

- When you told me that you
loved me this morning...

I froze.
- Yeah.

- I knew that it meant
that we moved up a level

in our relationship.

And...for me,

that level comes
with a lot of baggage.

- Like Killer Frost
and The Flash?

- Yeah.

- So you thought
that pushing me away

was the thing to do?

- I thought
that I was protecting you.

Clearly I was wrong,

because not only
did I lie to you.

I lied to myself.

And you know what?
