Miraculous and The Flash crossover: Collision of Worlds. (Book 4)

Now, Hawk Moth arrives at a seemingly abandoned warehouse.
He pushes one of the large sliding doors open, and enters the pitch black warehouse.

Hawk Moth: I'm here, just as you requested. Now, where are you?

After stepping a few feet inside, the door shuts, seemingly on its own, with a loud thud.

(THUNK!)

Now left completely in the dark, Hawk Moth looks around for any sign of trouble. Believing that Falena Falco, or possibly Reverse Flash, was trying to spring some sort of trap.

Hawk Moth: Where are you?! Show yourselves!

Suddenly, the large monitor lights up, along with a few other lights. At the center of the lair, was a round table, was Future Lila in her civilian outfit, a smug grin stretched across her face. With his yellow cowl down, Reverse Flash approaches the table and stands next to her.

Thawne: Welcome, Mr. Agreste. We've been expecting you.

Hawk Moth: Professor Thawne.

Thawne: We're so glad you could make it to our little…shall we say, “conference.”

Hawk Moth: Stop the small talk. Why did you summon me?

Future Lila: Have a seat, Gabriel. And we'll gladly explain everything.

With no other options, Hawk Moth takes a seat.

Future Lila: Now then, to business. As I'm sure you know, your nephew Felix infiltrated your house. And attempted to steal some files from your computer.

Hawk Moth: That's right. How do you know about that?

Future Lila: Simple. I was the one who sent him there.

Hawk Moth: Why you-!

He attempts to get up, but Thawne rushes up and stops him.

(ZOOOOM!)

Thawne: Sit down.

Hawk Moth begrudgingly sits back down.

Meanwhile, at that same time. Flash stands on a rooftop, interrogating Argos.

Flash: Okay, Argos, start talking. Because I want answers.

Argos: What do you want to know, Barry?

Flash: Don't call me that, only my friends call me “Barry.”

Argos: Is that to say your enemies call you Flash, then? Because you've certainly made a lot of enemies, since you've been working with Ladybug.

Flash starts getting annoyed with Argos.

Flash: Stop changing the subject. Cat Noir said that you impersonated your cousin, Adrien, and snuck into his house. I want to know why you did so, and why the heck you look exactly like Adrien?

Argos: Well, there's a good reason for that. My mother is the younger twin sister of my aunt, Emilie Agreste. It's basically genetics.

Flash: Uh-huh.

Argos: And as far as infiltrating the Agreste Mansion, my purposes just so happened to coincide with some else's.

Flash: Really? What purpose was that?

Hawk Moth: He wanted the Peacock Miraculous.
And in exchange for it, he'd trade the ring he stole from me, and the information he downloaded onto a USB.

Future Lila reaches into her pocket, and takes out a USB

Future Lila: You mean this information?

She plugs the USB into a projection device on the table.
On the holographic projection, the incriminating evidence that Felix stole from Gabriel appears.
Hawk Moth becomes furious, as he realizes what he was looking at.

Hawk Moth: Where did you get this?!

Argos: I copied the files from Adrien's computer, and downloaded them to my phone. And once I transferred the files to the decoy USB. All I had to do was convince my uncle to give me the Peacock Miraculous in exchange for his ring, and the USB.

Flash: And what exactly were you planning on doing with the other copies of those files?

Argos: I transferred them to an anonymous source, and headed back to my home, in London.

Flash: And exactly what did this anonymous source want with those files?

Hawk Moth: An insurance policy?

Future Lila: Yes. You see, I knew if I were to akumatize people here in this time, you'd become suspicious. And try to disrupt my plans to obtain the Miraculouses. Which is why I had Felix sneak into your house and download these, to use as my insurance policy. So that way, if my plans went sideways, or if you decided to stick your nose in my business, I'd have everything I'd need in order to take you down with me.

Hawk Moth balls his fist, quietly seething with fury, Future Lila grins deviously.

Future Lila: Doesn't take the Moth Miraculous to feel the pure rage and hatred coming from you, right now.

Hawk Moth glances at Thawne.

Hawk Moth: And how do you play into this, Reverse Flash? What exactly do you two have planned for the heroes?

Argos: I don't know, they didn't say. And I didn't bother asking. But I do know that my uncle isn't the man that my cousin thinks he is.

Flash: I know. He's the man behind Hawk Moth's chrome mask. Ladybug told me she thought he could've been Hawk Moth, but since he was akumatized, she completely dropped him from her suspect list.

Argos: But you haven't?

Hawk Moth: No, he hasn't. He's on to my operation.

Thawne: I told you, it's what Barry does. He always follows an investigation through to the end. Always snooping around where he shouldn't. You have no idea how truly irritable it is, sometimes.

Future Lila: And of course, now that he knows your identity, Gabriel. He'll be coming for you.

Hawk Moth: How could he possibly know my secret identity?

Flash: Courtesy of my friend, Lila.

Argos: The Italian liar? I wouldn't trust her, if I were you.

Flash: What do you mean?

Lila (CL): “Barry, don't listen to him! He's just trying to manipulate you!”

Argos: She's just as deceptive as my uncle.

Flash: Which reminds me. You said that you knew something about the Agreste family that I didn't. It can't be Hawk Moth's secret identity, because you know that'd be wasting my time, since I already know who he is, thanks to Lila.

Argos: You're right. I know exactly what my uncle is planning. I know why he wants the Miraculous of Ladybug and Cat Noir.

Flash: And why is that?

Argos: To bring my aunt back to life.
