no one lives forever.
Grey, I don't even want to hear you talking like that, man.
As long as we're connected,
I'm nothing more than an anchor around your neck.
Which is why you must help me.
I don't understand. I...
Not Cisco's drug.
Gideon resynthesized the liquid.
She assures me it will free you from my body's biology.
And it will free you of mine.
I'm the only thing that's keeping you alive, man.
You're asking me to kill you, Grey.
I'm asking you to let me die so that you may live.
Please hand me the vial.
I-I know-- I know you think you're strong enough for both of us.
But unless I do this, we'll both die.
Then we'll both die. I don't--
You have your whole life ahead of you.
But now it's time
for you to let me go.
No, I'm not ready for you to go.
I'm not either.
But when you think about it,
compared to the Cosmos,
one's life is but a blink of an eye.
You're gonna lecture me about astrophysics right now?
Grey, please don't do this to me.
I can't do this.
You once told me...
that I was like your father
and I said you were my son.
How could a father do anything less?
- Grey. - Please. Please.
-不要 -谢谢你 杰佛逊
- No. - Thank you, Jefferson.
Grey, no, don't.
Stay with me, please.
I'd prefer not to be alone.
tell Clarissa and Lily that I love them.
Thank you, Jefferson...
for the adventure of a lifetime.
I hope your life is long
and full of love.
Just-- just as mine...
He did it for me.
I'll get it, honey.
How are you holding up?
I'll cry at the funeral.
We need to gather everyone.
Overgirl's gonna go nuclear,
and the Earth-Xers are gonna use their Waverider
to threaten Central City
and leverage us into surrendering Kara.
How do you know that?
It's exactly what I would do.
- I'm sorry. - For what?
For being so weak.
I've managed to stabilize her deterioration,
but without a transplant she'll be dead within an hour.
Now don't you listen to her.
There is more strength in you
than in this entire planet of lesser humans combined.
Yeah, I didn't want to feel left out.
Where are we with locating the other Waverider?
We got a pretty good idea.
I mean, we've all heard
of the Chandrasekhar Limit, I assume?
The data indicates it's still
in the vicinity of Central City.
Which also indicates that Overgirl
isn't long for this world.
Which means that this world
isn't long for this world.
Failure's not an option.
Losing is not an option. We are gonna win.
And we are gonna show these people that this earth
- belongs to us. - Great speech.
Sorry to interrupt, Mr. Queen,
but we're being hailed by a fellow Timeship.
Put it on.
What do you want?
To offer a truce.
In exchange for what?
We will return to our earth peacefully
if you meet my one demand.
Supergirl comes with us.
Here's another difference between you and me.
I don't abandon my friends.
- Everybody ready to go? - Never been more.
We can't bring Marty back,
but we can protect the city he loved,
and the family he left behind.
For the Professor.
Now let's go kick some ass.
Let them run.
We'll turn this city into a mausoleum.
Kill them all.
You can't just go around roasting people.
You ever heard of due process?
Rule of law?
Could use a little help here.
I got you covered.
This is just like Star Raiders on Atari except it's real.
Cut the chatter, Red 2.
