The hum of fluorescent lights was constant in the lab. So constant that Albert Wesker had tuned it out as he moved from station to station, running analyses of samples, reviewing data and singling out key features he wanted to improve. It was peaceful. This is peaceful. This is heaven…
… And then the door hissed open.
Before the metal plate could completely clear the opening, a shoulder collides with it, followed by a muttered indignation. “Fucking… Stupid door… Fucking thing needs to open faster, I swear to-” William Birkin’s voice filled the once peaceful lab. Wesker didn’t acknowledge his compatriot until the sample he was holding had the pipette out of it, the cap was closed, and the glass vial was back in its secured carrier. “William….” He began and turned slowly, discarding of the latex gloves he was handling the sample in. “Forgive my… Crude wording… But…. Who pissed in your cereal today? I haven’t seen you this… Agitated since your confession to Annette was disrupted by a disgruntled oppossum…” Albert snickered.
Usually, Birkin would jab back at the other blond, it would blow up, and the two would be at each other’s throats until the next morning, when one would leave the other coffee on his respective station’s coaster. Today however, Birkin just dropped into the stool next to Wesker and slammed his head onto the metal work surface.
A groan left him, and Wesker’s eyebrow raised at the rare sound. “... My sister is in town…” William explained, voice muffled. “... I didn’t even know you had a sister.” Albert retorted flatly. “Ugh. Because she and I are… Fundamentally different!” The collapsed man squawked before continuing. “Do you want to know something?? On my way here, I got a call from the police station. Not the one in the fuck-off-far city I thought she was living in, the fucking RPD!!!” Birkin hissed, running a hand through his hair over and over again, disheveling blond locks.
“Albert, she was arrested! And what for, you may ask?? For trespassing! And what’s worse?! SHE BROKE INTO AN ABANDONED BUILDING!” William’s arms fly up and he begins to pace the length of the lab. “Now I have to go pay her bail and figure out why the fuck she’s here, how long she’s been here, and possibly even change the locks, because I’m fairly sure she has a key to my door still!!!” He shrieks, shoulders heaving with effort.
Wesker just puts a hand on his shoulder. “William. You are being… A touch dramatic… I do not think you need to go as far as to… Change your locks.” Birkin just stares at him out of the corner of his eye. “... Aren’t you heading to the RPD today…?” He asks slowly, in that tone that means he’s already thinking about how to word something complex. Wesker’s hand dropped and he slid off his lab coat, draping it over the back of his chair. “I am. Why? Are you wanting me to deliver a telegram to your delightful little sister?” He snickers. Birkin’s nose scrunches. “... Don’t… Don’t say it like that… No. You’re opening up a new division in the police department aren’t you? We twisted Iron’s arm to make you captain, didn’t we?”
“... William, I hardly see what my side project has to do with your-”
“You owe me a favor, Albert.” The interjection is sharp. The silence following is sharper.
“... What is it… That you want… William…”

“What were you looking for?!” The demanding words of Enrico Marini echo in the tight confines of the interrogation room. The officer paces the stretch of tile, eyes wide and wild.
“What was so fucking important that you had to break into a secure facility, risk your life, and get caught by my cops?? HUH??” Marini barks. Y/N’s eyes, half lidded and calm, trace him as he stalks like a stressed out tiger. “... Your blood pressure must be obscene, officer.” She remarks and leans back on the uncomfortable metal chair. “I don’t think I want to say anything until my brother arrives. Thank you.” The younger Birkin chirps dismissively, lips curling at the corners and head tilting in mock sweetness.
Enrico’s palm collides with the stainless steel table as the only door to the room swings open. He whips around, eyes narrowed and freezes. Breath caught in his throat.
“I’ll take it from here, Enrico.” A barbed–and yet velvety–voice settles over the ringing from the table’s impact. “Captain, I was just-”
“I said, I will take it. From here.” Wesker dictates without looking up from the arrest report he’s holding.
Silence settles for a second too long, a sentiment displayed by the Captain’s piercing blue eyes flicking up over his dark lenses. They stare down the officer, almost into submission, before Marini swallows down his protests and stomps towards the entrance, forcing it open with too much force.
As the metal door sings its song of contact, the blond settles gracefully across from Y/N.
He taps the report to straighten it, and lays it flat. Her name displayed in bold on the front page. Her eyes flit from her own name to his face.
“I’m not speaking to you or your… boys until my brother-” “William sends his well wishes.” Wesker cuts her off, balancing an ankle over his knee and folding his hands. He stares up at her and tilts his head. Despite the dark lenses, she can feel him staring…
Her posture shifts into something less… Rigid. Something nonconfrontational. Carefully rehearsed. “... He’s not mad at me…Is he?” She coos, tone coated with false sweetness. With a mini shrug, the performance continues. “I mean, what did he expect? He left such interesting stories out, and I’ve always been an inquisitive little sister… Is that a crime?” Her head tilts, mirroring his and her lashes bat.
When the act doesn’t garner a reaction, she drops it with a huff, rolled eyes, and a hard flopping back against her seat. The Captain raises a perfectly blond eyebrow.
“Stories, Ms. Birkin?” His voice wraps around the interrogation room with an underlying interest woven through the timbre. Y/N’s gaze meets him again. Measures it. Then she speaks. “... Stories. Fantasies. Ramblings about… Monsters.”
Wesker is silent for a heartbeat; arms crossed over his chest, studying the woman across from him. “... Monsters, Ms. Birkin?” He finally chuckles. “Such an… Inelegant word for…” He stops himself and grins–lips pull back to reveal perfect white teeth in an expression that feels more like a barring of fangs rather than a smile.
“Why don’t you tell me about these… Imaginary creatures…” He purrs coaxingly.
~~~
“I mean seriously, nicknaming it Tyrant? How… Dramatic.” Y/N snickers softly and shakes her head, continuing. “But… Willy-boy never was the creative type.” A mocking pout settles on her face as the room falls quiet again…
And then
A sound.
It’s muffled, but in the silence… It’s loud
Laughter.
Y/N’s eyebrows furrow in confusion as her eyes narrow at him. Before she can speak, he raises his head, glasses sliding down just enough for the younger Birkin to meet his wildly manic gaze. Wesker lets his hysterics subside as he sits up, spine straight once more. “... Ms. Birkin… I have never had anyone shamelessly call my decisions dramatic or lacking creativity…” He hisses through clenched teeth bared fangs.
The room drops a few degrees as the woman swallows and stares at him, still trying to sustain her carefully crafted demeanor.
“What are you talking about…?” She whispers before her eyes go wide. “... You’re-”
His grin stretches, eyes focused fully on her.
“Nice to meet you, Little Birkin…
My name...
is Doctor Albert Wesker…”
