How did any of them get here? The father was tricked, but found an enjoyable life. The Other was sent here to be given life. And the lovers were drawn here by each other.

They didn't know how, but they didn't care.

They wouldn't trade what they had for the world.

Localized

For the past three days, Adam had to spend as much time in the entry plug as possible. He'd usually spend eight hours in the plug, and take an hour break. His father said that they couldn't afford to be surprised by the next Angel. What was different about this Angel, he didn't quite know. Usually, he didn't mind spending so much time here, but today… something was different.
"Dad, how much longer am I going to have to spend here?"
"I thought you liked it."
"Usually I do. But today… It feels hollow."
"How do you mean?"
"It feels like… she isn't here. Like there's just a shadow."
"She's probably waiting in her Simulation body until she's needed."
"I hope so."
"Don't worry, bro. You'll see her soon enough."
And so they went back to waiting.

In the command center, Dr. Mondschein was pacing. Why wouldn't this last Angel show itself, so they could deal with it now?
"Any sightings, Lieutenant?"
"None yet, sir."
"Alright. Open a channel to Mr. Fisher."
"Channel open."
"Mr. Fisher, how are the defences coming?"
"Well," Allan Fisher's voice said over the speakers, "Most of the defences were up yesterday. Now we're just fine tuning them to make sure the Final Angel blows up real good."
"Alright. Notify me if any problems arise."
"Can do, Doc. Fisher out."
Then Lieutenant Barret yawned.
"Tired, Lieutenant?"
"No, I'm just bored!"
"Well, suck it up. You gotta keep on your toes. You got that?"
"I guess."
"But he's right, Dad. This is boring! Can't you at least put us in the field?"
"No, Quatre. I can't. We'll get the drop on the Angel. If you guys are deployed, then the Angel will just ambush us."
"But If we're out there, we can act more immediately!"
"… You have a point. Adam?"
"I'm down with that."
"Alright. You guys are going to spend four hours up there, then four down here. Got it?"
"Got it."
"Got it."
"Alright. Lieutenant, launch Unit-04 and 14."
"Alright, Sir." He said, in a bored voice. "Launching."
The Evangelion units shot up to the surface.

"About damn time! Some fresh air!"
"Quatre, you can't breathe."
"… Touche."
"Anyway, what now?"
"Now we wait."
"We could have done that in there!"
"We could have, but now we're outside."
"… Touche."
"… Wanna wrestle?"

"If you two start wrestling, I'm going to personally kick both of your asses!"
"Come on, Sir! We need something to help us keep our sanity! We've been at this for three days!"
"No, if they waste their energy, then the Angel will have an advantage!"
"… If you're not going to do something…"
He switched off all communications, instead playing a song over the loud speakers. (.com/watch?v=CswqKzLG7dE)
"Then I will."
"… Lieutenant?"
"Doctor, there's something I need to tell you. Actually, closer to two things. Well… Three."
"… I'm not liking where this is going."
"Number one: Someone did supply the signal to activate the angels."
"… You work directly for SEELE, don't you?"
"Guilty as charged. I sent the signal after Project Telefrag and awakened the Angels."
"You son of a bitch."
"Number two: Vent climbing is a Lilithian trait."
"So the last angel…?"
"Has been in the base the whole time."
"What's the last one?"
"And number three: Do you know how easily an Angel's core can merge with Lilim anatomy? Especially when the core itself it Lilithian?"
"You're not…"
He rose into the air, the air around him shimmering.

I am.
Through license of she who is called "I Think," I have come.
Made by combining the fake with the real, I have come.
I am that which draws you into the darkness.
I am that which takes away your control.
I caused the first great fall, and exiled humanity from paradise.
My goal is simple. I will return home.
You will not stop me.
I am temptation.
I am The Snake.
You will fail.

"You're the last angel?"
"More appropriately, the last core resides within me. I am merely a vessel."
"Well then. That means that your body is still human?"
"Correct."
Dr. Mondschein ripped off his left sleeve, revealing the patch of AR Energy.
"Let's see how AR energy reacts to AT Fields, shall we?"
His hand glowed a bright blue, and he motioned as if he were throwing it. The blast impacted with the AT Field.
"Doctor, it appears that AT energy doesn't like AR Energy. You might be on to something."
"There's a lot more where that came from!"
"But I'm not willing to sit here while you wittle away at the light of my soul."
The consoles and chairs in the command center all rose up, and floated beside Barret.
"Time to die, Doctor."
All of the objects were flung with incredible force towards Dr. Mondschein. He merely stood there.
"I don't think so!"
A blue field appeared in front of Dr. Mondschein, and the objects bounced harmlessly off of it.
"You can generate your own ARKS. Impressive."
Dr. Mondschein threw barrage after barrage of AR Energy at the AT Field, while Barret continued to throw pieces of the command center at him.
"One of us is going to fall, doctor. And it's not going to be me."
"What makes you say that, you lovecraftian piece of shit?"
"Another trait of Lilithian cores."
He vanished. Dr. Mondschein looked frantically about the command center.
"We always turn up where you least expect it."
He turned around, and found Lieutenant Barret standing far too close for comfort. He threw his fist at Barret, but it just impacted the AT Field.
"Good night, Doctor."
Then Barret's fist flew at Dr. Mondschein.

"That's odd…"
"What?"
"The comm is down."
"Why's that?"
"Base sensors are still online. Hold on, let me check."
Unit-04 froze in place temporarily, something that happened whenever he went into NERV AI mode. When Unit-04 started moving again, it bolted back towards the catapults.
"Quatre, what is it?"
"Pattern Blue! INSIDE of NERV!"
The catapults refused to move.
"Come on you piece of SHIT! MOVE!"
"Quatre! What about the hole the last Angel dug?"
"We've already filled it and repaired the ceiling in the hallway."
"Well, what do you have for a right arm?"
"A drill, why?"
Unit-14 just stared at Unit-04.
"… Right! A Drill!"
He stepped away from the Catapult and lifted his right arm high above his head.
"Next stop: NERV!"
And he plunged it into the ground.

The Angel floated through the halls towards The Garden. Odd that no ventilation system lead directly to his destination. Oh well. He'll just to travel the old fashioned way. He came upon the frozen door leading to The Garden.
"Home, sweet ho-"
And the intricate defence system set up around it.
"That's not good."
"OPEN FIRE!"
Two Eva sized miniguns, the rifle from Project Telefrag, the old MSBU Drill, and some weird sticks among other things pointed directly towards Barret. Projectile after projectile impacted with the AT Field, slowly weakening it. Then a couple of energy blasts managed to pass through the AT Field and hit him square in the chest.
"What the HELL was that?"
"THAT was Magic Missile, you prick!" Allan Fisher yelled out, "I KNEW Magic was a good idea! It passes through AT Fields!"
The sticks, now revealed to be wands of Magic Missile, opened fire on Barret. Impact after impact tore away at his NERV-Uniform.
"Not good… Not good… So close…"
He curled up into a ball, projectiles still weakening the AT Field.
"ENOUGH!"
He threw his arms and legs out wide, and a massive wave passed through the hallway. Every weapon was torn to pieces, and Fisher was thrown against the door.
"I feared for my life there, Fisher. Nice try."
Then the ceiling cracked.
"ADAM Damnit."
And the two Evangelion units burst through.
"OH YEAH!"
"Time to kick some… Barret?"
"Pattern Blue is coming from him! Kick his ass!"
The silver Evangelion raised the drill again, and brought it down upon The Angel's AT Field.
"It's going to take more then that to-"
"Activating AT Field, bitch!"
The drills AT Field activated and bore through Barret's own AT Field.
"Oh no." He said sarcastically, "Whatever shall I do?"
"You can die, for one!"
The drill opened up and grabbed hold of Barret.
"Any last words?"
"I'll save those for when I die."
"I'll take that as a no!"
He detonated the Anti-Matter tip. But the explosion never came.
"Oh right, I forgot to tell you! I deactivated the detonator when I set up your drill! Sorry about that!"
"I can still crush you!"
"No. You can't."
He vanished and reappeared next to Quatre's right shoulder.
"You have your… 'Brother'… to thank for this trick."
He deactivated his AT Field and reactivated it. The sudden generation of the shield cut off his right arm.
"GAH! FUCK! ALWAYS THE RIGHT ARM!"
The green Evangelion grabbed Barret from mid air, and slammed him against the wall.
"Why won't you stay still?"
"If I did, I'd die. And I don't want that. Not yet."
He activated his AT Field again, cutting off Unit-14's right left hand. Then Barret's left arm started to glow.
"I also learned this trick from my brothers."
He raised his left hand and pointed it at Unit-14.
"This is gonna hurt…"
A familiar Impact Laser shot out and broke four of Unit-14's AT Fields and sent it flying into the wall.
"Now, if you'll excuse me, I have an appointment in The Garden."
He fired his Impact Laser again, and broke through the doors. The doors went tumbling through, destroying countless artificial Angels. He came up to the back wall. The wall slid open revealing the black giant residing within.
"Now to break you out."
And he started to chip away at the ice.

Dr. Mondschein woke up in the destroyed command center. He looked around, looking for Barret.
"Where the hell did you go?"
But of course, he was no where in sight. He walked over the debris, looking for Barret's old terminal. Someway, some how, it remained intact.
"… Don't look a gift horse in the mouth, Dream."
He turned on communications and scanned the surveillance. Barret was already inside The Garden. Unit-14 and Unit-04 were wrecked in the hallway outside.
"Wait, where's Fisher?"
Then he noticed something. Fisher's twisted body among the wrecked weapons.
"Damnit! DAMNIT! We couldn't stop it… We failed!"
He opened a channel to Quatre and Adam.
"Quatre, Adam, one of you, respond."
"… Dad?"
"Right here."
"We failed. We couldn't stop it. We tried, but it wasn't good enough…"
"Alright, there's nothing more we can do. The point is, you tried. Now, you two come back to the command center. There's one last thing we can do."

He reached it. His goal. He was returning home. The Black Giant called EVE thrashed about. Barret floated towards it, and they became a singular being.
"Anti-AT Field detected. It happened, Dad."
"Activate the ARKS."
"Don't need to. The Anti-AT Field is only spreading two kilometers in every direction from contact."
"So, he wasn't a proper Angel either?"
"No. Instrumentality is happening, but it's become localized."
"… Alright. Well, I guess we can try to stop it."
"Operative word here being 'Try.'"
"I guess."
"Here we go, Dad." (.com/watch?v=w2cFEHM9yMw)
"… Appropriate."
Endless copies of EVE poured out of The Garden. They hunted down every last person in NERV-Alaska and absorbed them. Quatre stood on the surface, and looked at the now red sky. Dr. Mondschein stood on his shoulder, lab coat blowing in the ominous wind.
"Here they come."
Copies of EVE appeared on all sides of them.
"… I'll take the endless amounts on the left. You take care of the endless amounts on the right."
"You got it."
He jumped off of Quatre's shoulder, and stood on a patch of blue AR Energy. He walked forward, throwing AR Energy at everything he saw. Quatre ran forward and tackled one EVE. But there's only so much you can do with one arm.
It wasn't long before they were completely overrun. Eventually, Quatre was swarmed by EVEs and was ripped apart. Dr. Mondschein's AR Field eventually faded away.

But as the EVEs came upon him, he only smiled.

"There's one last thing we can do."
"What brilliant plan do you have, Dad?"
"We're getting you out of here. Both of you come to the command center."
"Got it. Come on Adam."
He waited for the two Evangelions to show up. He turned off the music that had been playing since the start of this attack. One last act of defiance.
"Alright, we're here."
"Good. Quatre?"
"You want to see The Project."
"Yes."
Unit-04 knelt down in front of the command center, and the entry plug popped out of the back of his neck.
"Just like the first time, eh?"
"Yup."
He hopped into the Entry Plug. Quatre stood up again and the entry plug slid back in.
"The Project? What's that?"
"Just follow me, Bro. You'll see it soon enough."

They stood in a remote part of the facility. It was a round room, with just a liquid filled tank in the center. Inside the tank was a naked girl with wires in the back of her head leading towards a nearby computer terminal.
"What am I looking at, dad? Seriously."
"You know that memories are just electrical signals, right?"
"Yeah."
"What makes up the human personality is nothing but a series of signals from the brain."
"What exactly are you getting at?"
Dr. Mondschein walked over to the terminal. He smiled, a notification in the center of the screen saying "Upload 100%"
"Well… AIs are the exact same. Just electrical signals."
"AIs…?"
Dr. Mondschein typed something into the terminal, and the wires disconnected from the back of her head, and the liquid slowly drained from the tube. The glass slid up into the ceiling, and the girl was left lying there.
"You don't mean… You can't mean…"
Her eyes opened up, and she looked around. Green eyes.
"Unit-14 felt hollow because I put a copy in their while I worked on this."
"You didn't…"
She spotted him. Her eyes lit up, and she lunged at him.
"ADAM!"
"Adam Mondschein, meet Allison Catorce."
He wrapped his arms around her. She laughed, holding him in her arms for what felt like the first time.
"I can actually feel it! You're actually here!"
Dr. Mondschein took off his lab coat and handed it to Allison. She took it, without letting go of Adam.
"The point of that was to put it on."
"Not yet, Dr. Mondschein… Just a little bit longer…"
"I really hate to rush you, but we need to go as soon as possible."
"He's right. We need to go. Allison, put on your coat, we have to go."
He pulled another coat out of hammerspace and put it on.
"Come on."

They stood on the surface. Allison and Adam in their entry plug, and Dr. Mondschein standing on Quatre's shoulder.
"Dad, why are we out here?"
"AI, eject the entry plug."
The entry plug of Unit-14 ejected.
"Quatre."
"You got it, Dad."
"Dad, what are you doing?"
Unit-04 grabbed the entry plug and pulled it out.
"The nearest city is… That way."
Unit-04 turned to face the direction he was pointing.
"Dr. Mondschein, we're not leaving you!"
"You two don't have a choice in the matter. We can't stop this. We tried, and we failed. At the very least, you two are getting out of here."
"But dad-"
"No buts!"
Quatre lifted the entry plug and prepared to throw it.
"Dad! Don't do this! We'll fight with you!"
"I don't want you two to fight. You two finally got each other. Don't throw your lives away."
The comm. fell silent.
"You got that?"
"… alright."
"I love you both with all my heart."
"You two be good to each other, and if I find out that Adam did something to harm you, Allison, I swear I will come back and I will hunt him down."
"Good bye, you two."
And Quatre threw the entry plug with every last ounce of strength he could muster.
"… Good luck."

Somehow, they had managed to find their way back to the apartment. The entry plug managed to land a kilometre or two outside of town, and they managed to walk back. Neither of them felt the need to say anything. Nothing could be said. When they entered the apartment, they noticed a box was lying on the dinner table. Inside of it was a recorder, and a lot of cash.
"… What does it say?" She asked.
"I don't know." He pressed the play button. Dr. Mondschein's voice came out of it.
Hello Adam. Hello Allison. If you're listening to this then… Well, you know. I did what I had to do. I know you won't like it, but it was for the best. I wasn't about to let you die trying to stop something that couldn't be stopped. Originally, I was going to show you Allison, as a 'congratulations' if we won. But because the box is still here and you are listening, I showed her to you as a chance for you to find happiness after I'm gone. Now, if you look inside the box, you'll notice that there is a lot of money inside. Being the head of a secret organization helps on the financial front. That's enough money to let you live almost anywhere in the globe. Or, if you want, you can fly to Tokyo-3 and live there. Eva pilots are provided for there, after all, and you seem to have taken a liking to piloting. But… No matter what, I'm proud of you, Adam. Every decision you make will be the right one. It may not seem it at the time, but it will be. Because it will be your decision. Unless you decide to start moping about me being gone. If you do, I will haunt you. I've given you the materials, now live your life.
He shut off the recorder.
"Move on…"
"So… what now?"
"For now?" He grabbed her by the hand, "We have a sunset to watch."

They stood on the roof, watching as the sun sank below the horizon. A red dome marked the place where NERV-Alaska used to be.
"… Dad would have wanted a headstone as grand as that."
Hand in hand, they watched as the sun sank below the red dome.
"At least…" He turned towards Allison, smiling, "At least I still have you."
"Theres… one thing I want to try, now that I have a human body." She said, turning towards him.
"What's that?"
She put her hands on the sides of his face and kissed him. A warm, gentle kiss. But to her, it meant everything. She broke off, smiling.
"I finally got to kiss you!"
She hopped a little, in victory.
"You're a weird one. But that's why I love you so much."
He wrapped his arms around her.
"I love you, Adam."
"I love you, too."
And they kissed each other in the sunset.

They may have lost much. They will always miss what was lost. But in the end, they gained the one thing they've always wanted. And now, all they can do is move on with their lives, and enjoy every single moment they have.
