Callum left just after ten, with a promise, extracted mostly by Del, that he'd come back the next evening, and once his truck's headlights had swung out of the driveway and faded into the dark, Del turned back to Wren with the particular look of a woman about to say something enormous.
"Okay," Del said, dropping onto the couch beside her, close enough now that the earlier careful distance felt like it belonged to a different conversation entirely. "I think you deserve the whole truth, or as much of it as I can give you without my brother having a stroke about it. You feeling steady enough for that?"
"I've been steadier. I've also never been less inclined to wait for the convenient version." Wren pulled the blanket around her shoulders, some of the day's exhaustion settling into a wary alertness now that the worst of the cold had eased. "Start with the word he used. Bond. What is that."
"Okay. Start simple, work up." Del took a breath, the particular breath of someone about to say something they'd said before, to other people, in other contexts, and never quite gotten used to saying out loud. "Thornevale isn't an ordinary town, Wren. My family, most of the town's oldest families, we're not entirely human. We're wolves. Shifters. It's not a metaphor and it's not a cult thing, it's a literal, physical fact of what we are."
Wren waited for the part of her that should have laughed, should have pushed back with the reasonable skepticism of a woman being told something absurd, and found instead that it simply didn't arrive, not after five days of watching her own body do things medicine had no explanation for.
"Okay," she said slowly. "And the bond."
"When a wolf meets their true mate, the person biology and instinct and something we don't fully understand all agree is meant for them, it registers. Usually at a rite like the one you went to, where the whole pack gathers and the scent recognition is strongest. It's not a choice, exactly. It just happens." Del's voice had gone careful now, watching Wren's reaction with real attention. "Callum's bond activated for you. In front of the whole pack. And then he rejected it."
"Which does what, exactly. Why does his rejection make my body act like it's shutting down?"
"Because the bond isn't a one way thing once it activates. Both sides feel it, whether or not both sides accept it. Rejection from one side leaves the other exposed, cut off from something the body's already started depending on. We call it the wane. It gets progressively worse the longer it's left unresolved. Fatigue, cold, eventually it can become dangerous in ways that aren't reversible if it goes on too long."
Wren sat with that for a long moment, turning it over, trying to find the edges of something that didn't have edges she recognized. "So he could kill me. By doing nothing."
"Not intentionally. God, not intentionally, Wren, whatever else you think of him right now, that's not what's happening." Del's voice had sharpened, defensive in a way that told Wren there was more history here than she was getting the full shape of. "There's a reason he did what he did. It's not a good enough reason, I've told him that myself more than once, but it's not cruelty. It's fear."
"Fear of what."
Del hesitated, the first real hesitation Wren had seen from her, and something in her expression shuttered slightly, the same careful withholding Wren had noticed in Ines days earlier. "That part isn't mine to tell you. It's his. I know that's frustrating, I know you're sick and scared and you deserve every answer right now, but some of this is genuinely his story, and I've already told you more tonight than he probably wanted me to."
Wren wanted to push, wanted to demand the rest of it right there in the firelit room, but something in Del's face, a tiredness under the loyalty, told her this wasn't a wall she was going to get through tonight. She let it go, filing the question away with the others accumulating steadily since she'd arrived in this town.
"Fine," she said. "Tell me the rest of what you can, then. How does this end. Is there a cure, a fix, something that doesn't involve me depending on a man who rejected me in front of an entire crowd of strangers."
"The bond can be completed after a rejection. It's not common, but it's not impossible either. It requires trust to rebuild first, and it has to be mutual, chosen properly this time, not just some instinctive reaction in a clearing." Del's mouth curved, something rueful in it. "It's also, and I say this as someone who loves my brother very much and finds him exhausting in equal measure, entirely dependent on him getting his head out of his own history long enough to actually let someone in."
"And if he doesn't."
Del didn't answer that immediately, and the silence sat heavy between them, the fire popping softly in the grate.
"Then we keep you stable as best we can," she said finally, quiet. "And we hope he comes around before it's too late to matter."
Wren looked into the fire, thinking about the man who'd sat across from her that evening with his hands folded and his voice carefully flat, watching her the way someone watches a wound they're responsible for and don't know how to close. She thought about the moment in the clearing before he'd said a single word, the half second of unguarded recognition that had felt more honest than anything he'd said since.
Whatever he was protecting her from, whatever fear Del wouldn't name, it was clearly bigger than either of them wanted to say out loud.
She didn't know yet what shape that fear took. But she was starting to understand, sitting in a stranger's living room with a truth about her own body that no doctor could have given her, that she wasn't leaving Thornevale in six weeks after all.
Whatever this was, she was in it now, whether she'd chosen it or not.
