Cal didn't sit back down.
He stayed where he was, standing in the thin space between us, shoulders loose, posture balanced in a way that looked practiced without ever having been taught. The fog hovered close, offset just enough to cast a second outline when the firelight shifted.
Borrowed.
Not claimed.
Claire watched him like he might shatter if she breathed wrong. "You need to rest."
"I am," Cal said.
That was the problem.
His breathing was steady. His pulse, when I focused on it, was even. Too even for someone who'd just become a proving ground.
The fog made a minute adjustment—no more than a tilt, a refinement of angle—and Cal's stance changed with it, weight redistributing cleanly across his feet.
Mirroring.
I cut my connection another notch.
The echo inside my chest lagged, then followed, imperfect and delayed. The fog didn't collapse.
It compensated.
Cal's gaze drifted to me. "It says you're wasting energy."
"Tell it to stop talking," Claire snapped.
He blinked, and for a heartbeat the calm cracked. "I'm trying."
The fog pulsed, displeased.
"It's easier when I don't fight it," Cal admitted. "It doesn't push as hard."
"That's how it teaches you to cooperate," I said.
"It says cooperation isn't the word."
I stepped closer despite the warning pressure prickling along my spine. The fog reacted immediately, compressing tighter around Cal's shoulders, sharpening its projection like it was protecting a calculation mid-process.
"Move away from him," Claire said.
"I can't," I replied. "Not without giving it what it wants."
Cal swallowed. His hands flexed once, then stilled. "It's not telling me what to do," he said. "It's showing me how not to fall apart."
"That's still control," Claire said.
"No," Cal said quietly. "It's alignment."
The fog rippled, pleased.
I felt the urge to strike then—not at Cal, not even at the fog—but at the space it occupied. To disrupt the pattern before it settled. Before the calm hardened into something permanent.
I didn't.
Instead, I knelt and pressed my palm to the ground, grounding myself in something solid and indifferent. The fog reacted late, tugging at me after the decision instead of before it.
That mattered.
"Listen to me," I said. "It's not here to help you hold together. It's here to see how much it can borrow without you noticing the loss."
Cal's jaw tightened. The calm wavered. "It says loss is inevitable."
"Yes," I said. "But timing isn't."
The fog stilled.
For the first time since it shifted, I felt resistance—not from Cal, but through him. A subtle mismatch, like a joint refusing to seat perfectly.
Cal winced. "That— It didn't like that."
"Good," Claire said.
The fog adjusted again, smoothing the interface, tightening its projection until the mismatch vanished. Cal's expression eased, the borrowed calm sliding back into place.
There it is, I thought.
Correction.
Not of action.
Of thought.
Claire took Cal's hand suddenly, squeezing hard enough that his fingers went white. "Stay here," she said. "With us. Not with it."
Cal's breath hitched. The calm fractured, fear bleeding through the cracks.
For a moment, he leaned toward her.
The fog leaned too—
Then hesitated.
That hesitation was everything.
I rose in the silence it left behind, heart hammering. "It can't finish like this," I said. "Not while it's still copying."
Cal nodded slowly, sweat beading along his hairline. "Then it's going to stop copying."
The fog pulsed once, dense and precise.
Agreement.
And as the night deepened around us and the fire burned lower, one truth settled in with cold clarity:
The fog wasn't testing Cal anymore.
It was rehearsing how to replace the need to ask.
