Crisis On Earth-X (Fan Fiction) (Arrowverse x Lucifer)

Chapter 6: The Discussion

In the Cortex

Everyone got back to the Cortex

Felicity says "Dayton Optical Systems calls it the Prism."

Harry says "What on Earth do they need a sub-light generator for? It's basically a spectral emitter that..."

Felicity and Harry say in unison "...uses Quantum Entanglement."

Jake says "You could also use it to create a stable fusion reaction."

Iris asks "Ok, which all means what?"

No one said anything and Iris says "No, guys, I would really like to know what you're talking about."

Lucifer says "I got this. The device they stole can be converted into a neutron bomb."

Then Harry and Felicity say in unison "Boom."

Iris says "I take it back."

Caitlin says "The bottom line is that we have to catch these..." 

Felicity then says "Parallel-Earth goose-steppers.

Barry says with his mask down "This might help."

Alex asks "Is that a Kryptonite arrow?"

Barry says "Yup."

Felicity says "I know I shouldn't have to ask this question, but I have to ask this question. Oliver didn't shoot Kara, did he?"

Barry says "Sort of. the other archer and flying woman are Oliver and Kara of Earth-XXX."

Jake says "When you said that Earth-X was horrible, you might have undersold it."

Alex asks "Wait a minute. How--How could there be another Kara?"

Lucifer says "There are an infinite amount of Kara's, Alex. Just like there are infinite Kryptons and infinite Earths."

Barry says "And my Doppelganger is with them from that Earth too. Married to Kara."

Harry says "He's an idiot."

Felicity says "Ok, if that arrow has not-so-Supergirl's blood on it, we c--"

Jake says "We could track it using Quantum analysis."

Harry and Felicity say in unison "We could."

Alex says "Hey, guys, I think I might have a quicker way."

Then they all go into the med lab and Alex says "These red blood cells are suffused with short-way radiation."

Caitlin asks "Solar radiation?"

Alex says "Yeah, incredibly high amounts. Like nothing I've ever seen.

Lucifer asks "Can you track it?"

Felicity says "Well, I once caught a deranged serial killer off his face cream, so... No joke. Heh!"

Barry says "Let's just do it and fast. They also have John's other creation... The Knight Auto-Cybernetic Roving Robotic-Exoskeleton. Or KARR for short. He said that its programming started to self-preserve and it got smart and hundreds of people died. John is somewhere feeling sorry for himself cause he wished that this never happened."

Jake says "He can't blame himself for it."

Lucifer says "Yeah, he can. He built a monster that is uncontrollable. He feels out of control of this situation now. How is KITT?"

Barry says "KITT's good. John is with him now. I don't think he was happy to see his twin though."

Alex says "He is KARR's twin? Where did KARR come from if John didn't think he would be here."
