It was the kind of morning that felt less like a new beginning and more like a reluctant continuation. The bunker’s air, usually a stagnant blanket, stirred with an unfamiliar chill, hinting at a malfunction Sam hadn't yet diagnosed. His internal clock, scarred by years of erratic schedules, nonetheless declared it too early for this level of activity, especially *his* level of activity. He was already deep in the library, a thick tome on Mesoamerican demonology splayed open, a half-empty mug of lukewarm coffee steaming gently beside it.
His fingers, calloused from weaponry and research, traced the intricate glyphs on the page. Sam had warned him not to touch anything, not without gloves, not without his express permission, and certainly not *alone*. But the OC wasn't Sam. He was *Casimir*. And Casimir, despite his fastidious adherence to most of Sam's rules, possessed an independent streak that manifested in quiet rebellion. His particular vice? A compulsion to straighten. Not just papers or books, but the microscopic imperfections in the universe, or at least, the bunker's corner of it. A slightly askew rug, a mug handle not perfectly aligned with a table edge, a misfiled report. It clawed at him, a tiny, insistent itch behind his eyes until it was corrected. And right now, the sheer *disorder* of the Winchesters' personal effects in this section of the library was a symphony of chaos.
He’d found the book not on a shelf, but tucked under a stack of old *Playboys* Dean had forgotten to re-hide. Casimir had spent a full hour, hands gloved, re-shelving each lurid magazine with meticulous care before even daring to touch the offending text. Now, the heavy tome, bound in what felt like dried, ancient leather, lay open. Its pages were brittle, the paper darkened by age, and the ink so faded in places that he had to angle the desk lamp just so to decipher the script. Sam would have taken pictures, run it through the spectral analysis software, cross-referenced it with half a dozen other texts. Casimir just… read.
A faint scuffing sound, distant but distinct, reached him from the hall. It was Dean. Not Sam. Dean moved like a bulldozer with a faulty muffler, all heavy footfalls and muted grunts. Casimir glanced at his watch. Too early for Dean to be up, unless…
“Casimir? You in here, pal?” Dean’s voice, raspy with sleep and nicotine, cut through the quiet.
Casimir quickly closed the book, sliding it back under the stack of *Playboys*. It wasn't the most logical hiding spot, but it was Dean's, and therefore, safe from Sam's eagle eye for misplaced lore. He smoothed the corner of the rug nearest him, a small, unconscious gesture. "Morning, Dean. Just... organizing."
Dean ambled into the library, his hair a rumpled mess, a faded Metallica t-shirt hanging loose on his frame. He squinted at Casimir, then at the general tidiness. "Organizing? It looks like a damn museum in here already. Sam's got everything filed down to the last dust bunny. What're you even *doing*?" Dean’s gaze flickered over Casimir, assessing. He was looking for something. Always looking.
Casimir pushed his glasses up his nose, a nervous habit. "Just... consolidating. Sam keeps certain texts spread across multiple sections. It’s inefficient." He hated lying, but the book felt… *different*. Not just another forgotten piece of lore.
Dean grunted, running a hand through his hair. "Right. Well, I woke up. Figured I'd make a coffee run. Want anything? My usual. Black as midnight, strong enough to wake the dead." He paused, a strange glint in his eye. "Actually, don't answer that. You want what you always want, right? That fancy tea with the little jasmine flowers floating in it."
Casimir tried to smile. "Just coffee, Dean. Black. Thank you." He deliberately didn't mention the specific brand Sam bought, the one that tasted like an old shoe. He knew Dean had his reasons for pretending not to remember his preferences.
Dean nodded, turning to leave. "Alright, be back in a bit. Don't go summoning anything without us, okay? Last time you got curious, we ended up with a demon trapped in the kitchen for a week. Sam was *not* happy about the scorched ceiling." He winked, but the smile didn’t quite reach his eyes. There was an edge to Dean's banter, a subtle undercurrent that Casimir had learned to recognize. Dean was withholding. Something.
As soon as Dean's heavy footsteps faded, Casimir retrieved the book. He hadn't just *read* it. He’d found a loose page, tucked between the spine and the binding, a single sheet of parchment that wasn’t part of the original text. It was thin, almost translucent, covered in script he didn't recognize, and had a small, crudely drawn symbol at its center.
He pulled it out now, carefully, his breath catching. It wasn't Mesoamerican. The script was too angular, too… European, perhaps. And the symbol… it wasn't a standard demon sigil. Nor was it an angel ward. It was intricate, a series of interwoven lines forming a central eye, but not an eye he knew from any occult text. It resonated with something deep, something primal. A cold knot formed in his stomach.
This symbol. He’d seen it before. Not in a book, not on a relic. He’d seen it in one of Sam’s dreams. A hazy, fleeting image from a therapy session he’d accidentally overheard through the thin walls of the bunker's makeshift infirmary. Sam had mumbled about it, about a 'shiver' he couldn't place, a 'cold eye' watching.
Casimir held the page in his hand. This wasn't just a book. This was a direct line into Sam’s nightmares. He didn't know what it meant, but the air around him thickened, suddenly charged. A prickle of unease crawled up his spine, whispering that this, whatever *this* was, was far more dangerous than just another monster of the week. He shivered. And then, he tucked the page into his own pocket, not under the *Playboys*. He had to know.
