There was no time for ceremony. The elder pressed the blade into Rourke's palm and Wren's in the same breath, murmuring words in a language Wren didn't recognize but felt anyway — a low hum beneath her skin, old and patient, like something ancient waking up after a long sleep.
"Blood first," the elder said. "Then the binding words. Quickly."
Rourke's cut was shallow, precise, a line across his own palm before he took Wren's hand and did the same to hers, so fast she barely felt the sting before their palms pressed together, blood mingling, his grip like iron around her fingers.
"Say the words after me," he said, low, urgent, his pale eyes locked on hers with an intensity that made the burning enforcer at the door and the war party breaching the treeline feel, for one suspended second, very far away. "*I bind my blood to yours. I bind my pack to yours. What is mine is yours to carry, and what is yours is mine to defend.*"
She repeated it, voice steadier than she expected, and the moment the last word left her mouth, something happened that no medical textbook, no rational explanation, nothing in Wren's careful, evidence-based life had prepared her for.
It felt like a door opening inside her chest that she hadn't known was closed.
She gasped — actual physical shock, her knees briefly buckling before Rourke's free arm caught her around the waist — as a flood of sensation poured through her that wasn't hers. Adrenaline that tasted like copper and cold air. A bone-deep readiness for violence that made her own pulse spike in sympathetic response. And underneath all of it, quieter, almost embarrassingly intimate: a thread of something that could only be described as *relief*, warm and startled, entirely Rourke's own reaction to whatever he was feeling from her in return.
"You feel that," he said. It wasn't a question. His eyes had gone wide, just slightly, the first genuine break in his composure since she'd walked into the pack house.
"I feel *you*," she said, breathless. "This is — Rourke, this is not what I expected a magical binding to feel like."
"It's not what anyone expects." His hand hadn't left her waist. For half a second, something passed between them that had nothing to do with war or debts or dead fathers — something that made her cheeks heat despite every reason she had not to let it. Then his head snapped toward the door, toward the sound of shouting growing louder outside, and the moment shattered as completely as it had formed. "Stay behind the wall line. Do not follow me past the tree markers no matter what you hear. Do you understand?"
"I'm a doctor. If your enforcers are hurt —"
"Then you'll be needed here, in the house, where triage can happen safely — not standing in the middle of a border skirmish where a stray claw doesn't care what your medical degree says." He was already moving, already shifting in ways she could feel now as much as see — a ripple beneath his skin, restrained and violent, the wolf just beneath the surface of the man. "I need you alive, Dr. Callahan. The bond doesn't survive one of us dying. Neither, probably, does the truce."
He was gone before she could answer, out into the dark with a speed that blurred at the edges of her vision, enforcers falling into formation behind him with the wordless discipline of men who'd trained for exactly this moment their whole lives.
Wren stood in the doorway of the pack house, heart hammering with a fear that belonged to both of them now, and felt — distinctly, unmistakably, threaded through the terror — Rourke's own controlled focus settling over her like a second skin. He was afraid. Not for himself. She could feel that distinction clearly, the way you'd feel the difference between two notes played close together. He was afraid for his people, and now, apparently, for her.
The elder appeared at her shoulder, expression unreadable. "Come. If enforcers come back wounded, I'd rather you know where the supplies are before you need them."

The next two hours passed in a blur of adrenaline and borrowed fear. Wren set up triage in the pack house's great room with a speed that surprised even her — pulling gauze and antiseptic from her bag, directing pack members half her size in strength but twice her calm to boil water and clear tables — grounding herself in the one language she'd always trusted more than words: the practical, unglamorous work of keeping bodies alive.
The first wounded enforcer came through the door forty minutes in, a deep claw wound across his ribs that made her stomach lurch even as her hands moved with clinical precision. The second came ten minutes after that, worse. By the time the third arrived, carried between two others, unconscious and bleeding from a wound that would have killed a human twice over, Wren had stopped counting how many times the bond flared hot and sharp with Rourke's own pain and fury from somewhere out past the treeline — small, sourceless spikes of violence that made her flinch mid-stitch, that she'd learned, within the space of an hour, not to ask about because there was no time and because some part of her already understood she didn't want to know.
It was well past midnight when the noise outside finally changed — shouting giving way to something quieter, more controlled, the particular hush of a battlefield settling into aftermath rather than crisis. Wren was elbow-deep in the third enforcer's wound, hands steady despite the exhaustion pulling at every muscle in her body, when the bond in her chest suddenly, violently, spiked with something that had nothing to do with battle fury at all.
Pain. Sharp, immediate, unmistakably physical, and unmistakably Rourke's.
She dropped the suture needle without meaning to and was halfway to the door before the elder's hand caught her arm.
"You cannot go out there," the elder said. "The Alpha gave you an order."
"He's hurt." Wren's voice came out rawer than she intended, some part of her genuinely frightened in a way that had nothing to do with obligation or bond-magic and everything to do with the memory of his hand at her waist an hour ago, warm and startlingly gentle for a man built entirely of violence. "I felt it. Something's wrong."
"Something is always wrong on a battlefield." But the elder's grip loosened, and something in her expression shifted — assessment, recalculation, the same look Rourke himself had worn across the firelit table before he'd offered her the blade instead of a threat. "The bond doesn't lie about pain, Dr. Callahan. If you feel it that strongly, it means the wound is severe enough that he's stopped shielding you from it — which means either he's too injured to maintain control, or he wants you to know."
Wren didn't wait to find out which. She grabbed her bag and pushed past the elder into the cold dark, following the pull in her chest like a compass needle through the trees toward the border — and arrived, breathless, at a clearing lit by torchlight to find Rourke on one knee in the mud, blood soaking through his shirt from a wound at his shoulder, and standing over him, very much alive despite the three Sinclair enforcers surrounding him with weapons drawn, a man Wren recognized instantly from a photograph she'd found tucked inside her father's burned ledger three weeks ago — a photograph she'd told herself, at the time, meant nothing.
"Well," said the man, smiling with teeth that weren't quite human anymore, "if it isn't Everett Callahan's daughter. I was wondering when you'd finally show your face."
