The dull throb in Alec’s left temple began insidiously, a whisper of static behind his eye. He tried to ignore it, focusing instead on the holographic display hovering above the mission table. Jace, ever-restless, was pacing a groove into the Ops Centre floor. Isabelle, perched elegantly on the edge of a console, meticulously cleaned a seraph blade, its silver glinting even in the dim light. Clary was sketching furiously in her notebook, occasionally glancing up at the map of demon activity in the Lower East Side.
“The reports are consistent,” Jace said, not a question, but a statement of fact. “Greater demon activity, high-level. They’re targeting leylines, not mundanes. This isn’t a run-of-the-mill infestation.”
Alec’s head tightened, a vice gripping his skull. He pressed a thumb against his temple, wincing slightly. He’d woken up feeling… off. A persistent, almost imperceptible ache in his teeth, a tell-tale sign of an impending headache that only he seemed to notice. Most people worried about losing their Shadowhunter edge; Alec worried about *losing his grip* on the edges of things, the subtle shifts in pattern, the minute details. It was a habit born of necessity, an early warning system for the chaotic world he lived in.
“Agreed,” Alec managed, his voice a little rougher than usual. He cleared his throat, a dry scrape. “The frequency is escalating. We need to identify the demon, not just contain the fallout.” He tapped a point on the map, a cluster of recent energy spikes. The sudden movement sent a jarring pang through his head. He blinked hard. The bright blue of the leyline energy on the display seemed to pulse mockingly.
Isabelle looked up, her dark eyes sharp. “Alec, you okay? You look a little pale.”
“Fine,” he lied, the word tasting like ash. He coughed, a short, sharp bark that vibrated through his sinuses, making his eyes water. The dull throb in his temple intensified, blossoming into a white-hot spear behind his left eye. It felt like someone had driven an ice pick through his brain.
“Right. Anyway,” Jace continued, oblivious, “I’m thinking we split into two teams. Izzy and I can take the initial scouting, see if we can pinpoint the source. Alec, you and Clary can coordinate backup, get the wards ready.”
Alec closed his eyes for a fraction of a second, fighting the sudden nausea that roiled in his stomach. The pain was expanding, wrapping around his head, crushing it from all sides. He could feel his pulse hammering against his eardrums, each beat a fresh assault. He coughed again, harder this time, a deep, wracking cough that made his entire body spasm. The impact was immediate: a blinding flash of agony that stole his breath, making him gasp.
“Alec!” Clary exclaimed, dropping her sketchbook.
He swayed, grabbing the edge of the mission table for support. The room spun. The intricate glowing lines of the holographic map blurred into an indistinct smear of colour. He opened his mouth to speak, but another cough seized him, more violent than the last. This one tore through him, ripping a raw sound from his throat. His knees buckled.
“Whoa, hey,” Jace was suddenly there, strong hands on Alec’s shoulders. “What’s going on?”
Alec tried to push him away, to articulate the agony that was consuming him, but all that came out was a wet, gurgling sound. His vision swam. He stumbled, pitching forward, and the next thing he knew, a wave of sickening nausea overwhelmed him. His stomach convulsed, and he wretched, violently, onto the polished floor of the Ops Centre. The acrid smell of bile filled his nostrils, and a fresh wave of coughs erupted, each one a hammer blow to his skull. He retched again, emptying what little was left in his stomach, splattering the expensive runes on the floor and the hem of his own jacket.
The pain was no longer a spear, but a bonfire, consuming his entire head. It was too much. More than he had ever felt. He crumpled, Jace barely catching him before he hit the ground. He heard muffled voices, a frantic murmur, but the words were a distant echo in the roaring sea of agony that was his head. He squeezed his eyes shut, but the darkness offered no solace; lurid, colourful patterns pulsed behind his eyelids, each one a fresh torment. A chill permeated his skin, though he felt flushed, burning. He coughed once more, a pitiful, broken sound, and then he was dimly aware of being lifted, of a powerful, familiar magic swirling around him, before the blackness finally took hold.

He awoke to soft light and the distinct scent of sandalwood and old books. Magnus. A faint hum of magic vibrated through the air, soothing. He was in his own bed, the silk sheets cool against his skin. But the relief was fleeting. The moment he tried to shift, a fresh wave of pain crashed over him, less intense than before, but still a throbbing, relentless drumbeat behind his left eye. He groaned, the sound raw.
“Alexander? My darling?” Magnus’s voice, a low purr, was immediately beside him. A cool, soft hand was on his forehead. “Oh, my sweet, you’re burning up. 102 Fahrenheit, just a moment ago.”
Alec blinked, eyes still sensitive. Magnus was there, leaning over him, hair artfully dishevelled, eyes full of concern. He had changed into silk pajamas, his usual flamboyant attire replaced by something softer, domestic. Alec could make out the faint, intricate silver embroidery on the lapel. It was strange, the pain making everything seem simultaneously sharper and hazier. He felt the phantom ache in his teeth again, a low, persistent thrum beneath the surface.
Magnus’s fingers, surprisingly gentle, brushed over his temples. “Your poor head. Clary called, quite frantic. Said you were… rather dramatic in the Ops Centre.” A small, worried smile played on Magnus’s lips. “She painted a rather vivid picture.”
Alec tried to speak, but another cough bubbled up, a dry, harsh rasp in his chest. He clutched at his throat, trying to stifle it, knowing what was coming. But it was no use. The cough tore free, rattling his entire frame. The world exploded into white light behind his eyes, a spike of pure, unadulterated agony that made a choked sob escape his lips. Tears, hot and involuntary, streamed down his face. He curled into a ball, whimpering, burying his face in the pillows.
“Shh, shh, my love,” Magnus murmured, his voice laced with profound sadness. He gently rolled Alec onto his back, carefully supporting his head. “It’s alright. Let it out. I’m here.”
He felt Magnus’s lips press a soft, lingering kiss to his burning forehead, then to his cheek, damp with tears. The touch was like a balm, a tiny island of comfort in the sea of his pain. He could feel the familiar magical energy, swirling around him, working to dampen the edges of the agony, but even Magnus’s formidable power seemed to struggle against this.
“I’ve already banished the mess from the floor,” Magnus said softly, stroking Alec’s hair away from his face. “And I’ve got some potions brewing. But this… this is different, Alexander. This isn’t a run-of-the-mill fever.” His gaze, usually so knowing and confident, held a flicker of something Alec rarely saw: uncertainty. “It feels… layered.”
Magnus’s brow furrowed, a slight wrinkle marring his perfectly smooth skin. He seemed to be listening, not with his ears, but with something deeper, more attuned to the magical currents. He leaned closer, pressing another kiss to Alec’s temple. “Just rest, my dear. I’m not leaving you.”
Alec closed his eyes, the persistent ache in his teeth now a distant, secondary concern to the blinding, throbbing pain in his head. Magnus’s presence was a comfort, a shield against the swirling chaos inside him. But even through the haze of agony and fever, Alec couldn’t shake the feeling that something more than just illness was at play. He just didn’t know what. And Magnus, for all his magic, didn’t seem to know either.
