I've decided to start a series of drabbles as a companion to "When the World Ends", but can be read as stories on their own.

Just be aware that this takes place in the same AU as the aforementioned story, where Allen was actually an agent of the Noah all along, just doing undercover work for the Earl.

These drabbles follow his adventures and misadventures as he adapts to Exorcist life while maintaining his secret.

"Remember, Neah my child, your mission is one of reconnaissance. Become their friend, make them trust you, and make them care for you. That way when we do lead our final attack, you can destroy them from the inside."

"Yeah, I understand. But what if my Innocence doesn't trick their gatekeeper? What if he senses I'm actually a Noah?"

The two were standing outside a sheet of intense white light. The number 07 glowed brightly in a cheery red. The Earl chuckled, glasses glinting dangerously. "If it fails to do that, what good is that filthy Innocence anyway? Now run along. We'll be in touch so you won't get too homesick, my child."

The Earl tapped Neah forward with his umbrella, which squawked an indignant "Lero!" The Musician paused just outside the threshold, let out a small sigh, and stepped through…

…finding himself nearly greeting a massive stone wall with his face. At least, that's what he thought it was until the newly christened Allen peered upward.

"Oh no."

It wasn't a wall. It was a cliff.

. . .

Of course the Black Order would keep their Headquarters on a cliff, Allen thought bitterly as his hand found another rocky outcropping.When the Earl said that the Ark would be dropping him off somewhat nearby,he obviously only measured the distance horizontally, notvertically. Scaling a massive stone mountain definitely was not highon Allen's list of fantastic ways to start off the day.

Clutching his bag in his teeth, he grimaced as the stones beneath oneof his feet crumbled away. The fall would be very unpleasant if he were to lose his grip, to say the least. Luckily for him, he had finally reached the top after his three hour trek andheaved himself up, lying on the precipice for a minute to catch hisbreath, staring at the sky. Under the open expanse of blue and white, a strange sort of peace and excitement overcame him. How long had it been since he was out on his own? Granted he was on a mission, but who said he couldn't make it fun?

Holding his hands into the sky in an effort to shield his face from the sun, he curiously studied his now pale-peach skin. It had been a while since he had seen this color rather than his usual smoky grey. He had to admit he rather liked it.

Once his arms stopped having the consistency of overcookednoodles, he got back on his feet and faced the large, menacing blackcastle that was to be his temporary home now. He couldn't help the small excited smile that graced his lips. He could be anyone he wanted to be, with a new life and a new name, and he was going to make sure he would enjoy it.

For the most part, the 14th Noah's first day as an Exorcist called "Allen Walker" went by without a hitch.

Almost.

He recalled his close call with the gatekeeper, who sounded the alarm due to the mark on his eye, forcing Allen to defend himself from a certain dark-haired sword-wielding Kanda Yu. It was probably a needed experience, Allen decided. It was a good opportunity for the Musician to practice holding back – he didn't want to draw unnecessary attention to himself by revealing how strong he truly was.

And then there was Hevlaska. He hadn't been expecting something like her at all, so when she examined his Innocence it was an understatement to say that he panicked, afraid that she would find something in his soul that would reveal him.

In the end, though, after Kanda's violent welcome and Hevlaska's prodding and Komui's "repairs", Allen could safely say that his infiltration was a success. Now that he was lying on his bed in his designated room, he felt like he could finally release the breath he had been subconsciously holding throughout the day. That is, until he heard the knock on his door, followed by fervent whispers.

"Lavi, he's probably sleeping. He must be exhausted after today."

"Okay then, we'll just wake him up. Oi, Allen!" The knock sounded again, louder than the last time. "Come eat dinner with me and Lenalee!"

"B-but if you're tired, feel free to rest and sleep," a soft, hesitant voice called.

"Lenalee! You're not supposed to give him an option! What if he doesn't want to come now?"

Allen closed his eyes briefly, listening to the whispered bickering escalate into a shouting match, before forcing himself out of his bed to stagger to the door. He might as well take this opportunity to get to know the people he would be spending his days with.

When he opened the door, he blinked stupidly at the sight before him. Was Lavi cowering in fear of the petite female exorcist… what was her name?

"Look, Lenalee," the redhead sputtered, "he's awake! I told you." She glared daggers at him before turning her gaze to Allen with all the gentleness of a sunrise.

"Hello, Allen," she said as offered him a brilliant smile –he wondered why his hands suddenly felt clammy– before continuing, "Lavi and I were hoping you could eat dinner with us so we can start getting to know one another, but if you're tired we can come back later." Lavi was about to protest her last remark, but Lenalee's sharp elbow to his ribs left him doubled over in pain, wheezing.

Allen's eyes flitted between Lavi's pained moans and Lenalee's bright smile, before giving a quick laugh as he ran his fingers through his hair.

This is going to be some kind of adventure.

"Sure, why not? I'm starved."
