CUT TO MANSION
Diana, in her job as an antiques dealer, is shown an ancient sword while visiting a mansion.

RICH GUY
It's the sword of Alexander. It's the blade that cut the Gordian Knot. It's a triumph.

DIANA
Yes.
RICH GUY
Enjoy.

DIANA
Thank you.

As Diana stares at the sword, Bruce comes from behind her.

BRUCE WAYNE
It's a fake. The real was sold in '98 on the black market. Now it hangs...

DIANA
Over the bed of the Sultan of Hajar. Excuse me.
Diana tries to walk away, but Bruce grabs her by the arm.

BRUCE WAYNE
Excuse me, Miss. The other night, you took something that doesn't belong to you. Stealing's not polite.

DIANA
Is it stealing if you steal from another thief?

BRUCE WAYNE
Who are you?

DIANA
Someone interested in the same man you are.

BRUCE WAYNE
Is that right?

DIANA
I believe Mr. Luthor has a photo that belongs to me.

BRUCE WAYNE
Did you get it?

DIANA
As it happens, no, I didn't. The data you copied is military grade encryption.

BRUCE WAYNE
You know. I bet with that dress 9 out of 10 men would let you get away with anything.

DIANA
But, you're the 10th.

BRUCE WAYNE
Mmm. I guess I am the first, to see through that babe in the woods act. You don't know me, but, I've known a few women like you.

DIANA
Oh, I don't think you've ever known a woman like me. You know, it's true what they say about little boys: Born with no natural inclination to share. I didn't steal your drive. I borrowed it. You'll find it in the glove compartment of your car. Mr. Wayne.

She then walks away, Bruce stares.

Cut to BATCAVE

Bruce connects the drive to a computer, the screen reads [ INITIATING DECRYPTION ]. As the decryption is on 2%, we cut to black…
…and a metal door opens. A visibly more aged Batman steps out of it, in desert clothing over his cowl.
Cut to RUINS
The door was that of a stone bunker in a seemingly desertic location, covered in ruins and barbed wire. Pillars of fire similar to volcanos surround the area. Batman looks through a pair of binoculars.
A fleet of truck arrives in the ruin compound. Batman approaches a truck as its back door opens.

BATMAN
Did you get it? The rock?
MAN
Yeah, we got it.

Batman enters the truck, opens a LexCorp box, and finds only green light bulbs.

MAN
I'm sorry.

Stormtroopers with Superman’s shield as shoulder patches reveal themselves to Batman and his allies.

TROOPERS
Get down! Get down! Now!

Another soldier points his rifle at Batman. He holds his hands up, and by turning around sees his men being executed.

BATMAN
NOOOOO!

Angered, he begins a killing spree, gunning down and brutally beating the multiple stormtroopers working for Superman. Although he manages to take down most of the stormtroopers while Parademons invade the area and abduct many of his resistance fighters, Batman is eventually overwhelmed by the remaining stormtroopers there who could barely restrain him. He snaps one of their necks but then is brutally (but barely) beaten down and restrained by the other stormtroopers. Seeing the damage that Batman was inflicting on the stormtroopers and their inability to restrain him, a Parademon knocks him unconscious.

Cut to UNDERGROUND BUNKER

Batman recuperates chained up in the bunker with his remaining allies, eyeing them helplessly. Superman himself then lands in the bunker, and his stormtroopers reverently bow before their leader. He approaches Batman, swiftly murdering the latter's other allies with his heat vision. Superman then unmasks the infuriated vigilante.

SUPERMAN
She was my world. And you took her from me.

Superman then rips out Batman's heart.

BATMAN
GGAAHHHHH!

CUT TO: BATCAVE
Bruce awoke from this nightmare to find a distorted and unstable blue portal of electricity right in front of him. Inside it is a mysterious time traveler...
FLASH
Bruce! Bruce! Listen to me now! It's Lois! It's Lois Lane! She's the key! Am I too soon? DAMN! I'm too soon! You're right about him! You've always been right about him! Fear him! Fear him! Find us, Bruce! You have to find us... find us...!

Bruce wakes up again. That was all a dream. The computer reads DECRYPTING [100%] - [DECRYPTION COMPLETE ] before opening a LexCorp branded interface.
