By full dark, Pietro had turned a dead machine yard into a laboratory using chalk, torn packing tape, and the kind of stubbornness usually reserved for family arguments.
Erikar watched him drag another pale line across the concrete.
One pace.
Three.
Five.
Ten.
The measurements were ugly. None of them were perfectly straight. The concrete had cracked in too many places for precision, weeds forcing themselves through old seams and rust stains marking where machinery had once sat long enough to become part of the ground.
Better that way.
Nothing about the yard resembled the House.
No buried chamber waiting under a church.
No black shell opening because an ancient room had decided he belonged to whatever it called inheritance.
No city grid carrying dead-red signals through Manhattan.
Just concrete.
Cold metal.
A river gone black beyond the fence.
And Pietro Maximoff crouched beneath a bad industrial light with half a piece of chalk between his fingers.
He finished the last mark and stood.
"There."
Wanda, leaning against one of the concrete barriers, looked at the arrangement.
"Very impressive."
"I know."
"You wrote five backward."
Pietro looked down.
Silence.
Then he rubbed the number out with his shoe.
"I was testing whether you were paying attention."
"Of course."
Erikar said nothing.
Pietro pointed the chalk at him.
"Do not encourage her."
"I haven't spoken."
"Exactly. Somehow worse."
The chalk went into his pocket.
Erikar shifted his left arm slightly.
Wrong decision.
The movement pulled along the damaged line from shoulder to upper back, and heat sharpened beneath the skin where the bridge machine had driven current through the House mark and used his body as part of its circuit.
Not severe.
Not pleasant either.
His body had already begun repairing the damage. That was obvious from the difference between now and several hours earlier. The deep electrical burn had gone from something intrusive enough to alter movement into something he could ignore provided he did not ask too much of the shoulder.
Normally that would have been sufficient.
Tonight, apparently, ignoring things had been outlawed.
Wanda's eyes moved from his face to the shoulder.
Only for a moment.
Then away.
He filed it.
The forklift station sat beneath the corrugated shed at the opposite side of the yard.
Pietro had spent nearly twenty minutes around it before sunset.
He had disconnected the charging assembly from the depot's dead wall feed, separated the old cables from anything leading into the building, checked the exposed wiring, then checked it again after Wanda asked whether he was certain.
The station itself was ancient by Midgardian standards. Heavy metal casing. Corroded terminals. A thick portable battery unit shoved beside it under a layer of dust.
Nothing elegant.
Good.
If the House managed to make that look mystical, they had larger problems.
Pietro moved into the open space between Erikar and Wanda.
His position was deliberate.
From there he could see Wanda, Erikar, and the forklift shed without turning more than his head.
Erikar noticed.
Pietro noticed him noticing.
Neither commented.
"Before either of you starts," Pietro said, "I want this clear."
Wanda pushed away from the barrier.
"No current."
"Correct."
"No deliberate magic."
"Correct."
She looked at Erikar.
"No contact."
"Yes."
Pietro nodded. "He stays where he is. You move."
Wanda's mouth tightened slightly.
Not objection.
More likely dislike at being discussed as an experimental variable while standing close enough to hear it.
She stepped toward the farthest chalk mark.
Pietro continued.
"If something changes, you say it."
"We know."
"I know you know. I also know both of you have terrible personalities."
Wanda looked at him.
He ignored that with the confidence of long practice.
"If either of you decides a sensation is too small to matter, I end the test."
Erikar said, "That seems subjective."
"So does manageable."
That landed.
Wanda glanced toward him.
Pietro's expression became almost pleasant.
"I've been waiting to use that."
"You prepared this argument."
"I had time."
He dusted chalk from his fingers onto his trousers.
"Baseline first."
Wanda exhaled through her nose.
Pietro pointed at her.
"You."
She looked down briefly toward the place beneath her clothing where the House mark sat.
"Present."
"That is barely better than him."
"I'm not finished."
Pietro made a small accepting gesture.
Wanda closed her eyes for perhaps two seconds.
Not reaching outward.
Not using power.
Listening to herself.
When she opened them again, the irritation had gone more focused.
"Pressure beneath the mark. Low. No pull. Nothing in my hands."
Pietro looked at her fingers.
No red.
"Pain?"
"No."
"Dizziness?"
"No."
"Anything from him?"
Wanda's gaze sharpened.
"No."
Good question.
Important answer.
Pietro turned.
"Your turn."
Erikar considered the problem.
"Stable."
Pietro stared at him.
Wanda's face did not change, which was worse.
Erikar amended, "The mark is active."
"And."
"Low pressure beneath the sternum."
"And."
"The shoulder remains damaged."
Pietro waited.
Apparently this was going to require absurd specificity.
Erikar lifted the arm a few centimeters.
The line across the upper back pulled again.
"Burning through the left shoulder. Extends across the upper back. Movement increases it."
Across the yard, Wanda's weight shifted.
Very slightly.
Her attention went to the shoulder again rather than his face.
Pietro asked, "How much movement."
"Enough to notice."
"That was nearly a normal answer."
"I regret it already."
"Good. We're making progress."
Wanda looked away toward the river.
Her mouth had done something small.
Not a smile exactly.
He chose not to investigate.
Pietro stepped backward until he was outside the path between them.
"All right."
The yard became quieter simply because they were ready.
Nothing in the environment had changed.
River against pilings beyond the fence.
A truck several streets away changing gears.
Loose metal tapping intermittently somewhere behind the plumbing depot.
One bad security light over the shed humming with ordinary electrical incompetence.
Erikar stood at the first chalk line.
Wanda stood at the far end.
Ten paces according to Pietro's measurements.
More in actual distance because Pietro's stride was irritatingly long.
The mark beneath Erikar's sternum remained low.
No sharper pressure.
No rhythm.
No answer.
Pietro looked between them.
"Move."
Wanda took one step.
Nothing.
"Anything?"
"No," she said.
Erikar shook his head.
Another step.
Nothing.
Pietro looked almost offended by the lack of catastrophe.
"Again."
Wanda moved.
The sole of her boot scraped lightly over concrete.
Nothing.
For several seconds, the impossible architecture beneath New York, the inheritance room, the marked circuit, the bridge machine, and everything else that had rewritten the categories available to Erikar's understanding of his own body amounted to three people standing around an abandoned forklift charger in a depressing yard.
A gull landed on the depot roof.
Looked down at them.
Apparently decided they were not food.
Left.
Wanda looked after it.
"Useful."
Pietro said, "It has better survival instincts than all of us."
Another step.
Nothing.
Erikar studied the absence instead.
Breathing normal.
Shoulder unchanged.
Sternum mark quiet.
Wanda's posture remained controlled. Arms loose. Fingers open. No visible power.
The distance had already closed considerably.
If proximity alone mattered, the effect either required less distance than expected or depended on something they had removed.
Current remained the obvious possibility.
The bridge had used enormous electrical density.
The city pulses had traveled through infrastructure.
The truck had responded through wiring.
The laundromat.
The streetlights.
The loose cable earlier.
Perhaps without current there was nothing to test.
Pietro lifted two fingers.
"One more."
Wanda stepped forward.
The mark under Erikar's sternum moved.
Not pain.
Not heat.
One additional beat.
His body went still before thought fully named it.
Then another.
A second pressure line seemed to form beneath the first, not deeper exactly, but offset enough that the difference became unmistakable.
Wanda stopped.
Immediately.
"Change."
The word came cleanly.
Pietro's head turned toward Erikar.
"Yes."
"What."
Erikar concentrated on the sensation without attempting to answer it.
"Pressure beneath the mark. Rhythm changed."
Wanda said, "Mine tightened."
Pietro looked at her.
"Pain?"
"No."
"Power?"
"No."
"Anything else?"
She waited a second.
"No."
Pietro pointed behind her.
"Back."
Wanda moved without argument.
One step.
The second pressure line weakened.
Another.
The rhythm beneath Erikar's sternum lost its extra beat.
"Lower," he said.
"Same," Wanda answered.
Pietro kept her moving.
By the time she returned near the far line, the mark had settled almost completely into the state it had held before they began.
Almost.
That distinction mattered.
Pietro came closer to Erikar, though not enough to enter Wanda's line.
"Baseline?"
"Nearly."
Wanda touched two fingers lightly against the fabric above her mark, then lowered her hand.
"Nearly."
No one spoke for a few seconds.
Pietro looked down at the chalk marks.
Then up again.
"So distance matters."
"Proximity matters," Erikar corrected.
Pietro frowned. "That is what I said."
"No. Distance may only be the measurement. We don't know the mechanism."
Wanda folded her arms.
"He means one observation isn't enough."
"I know what he means."
Erikar looked at the far line.
"Again."
Wanda said, "Yes."
Pietro closed his eyes.
Not long.
Just enough to communicate a great deal about his opinion of both of them.
"I hate that answer from either of you. Together, it becomes offensive."
Wanda was already returning to position.
Pietro pointed at her without looking.
"Slow this time."
"I understood."
"And don't anticipate it."
She gave him a flat look. "How exactly would you like me not to know what just happened?"
"By becoming less difficult."
"You first."
He considered that.
"Fair."
Erikar rolled the left shoulder once without thinking.
Pain caught under the scapula.
Wanda noticed.
Pietro did too.
He pointed at Erikar.
"Report."
"Shoulder."
"Different?"
"Movement."
"Then stop moving it."
Reasonable.
Annoying.
Pietro returned to his observer position.
"Same starting state?"
Wanda checked first.
"Mark low."
Erikar waited until his own rhythm settled.
"Low."
"Shoulder?"
"Burning."
Pietro's eyebrow lifted.
Erikar looked at him.
"I said it."
"You did. I'm proud."
"Don't be."
"Too late."
Wanda's breath left her in something dangerously close to a laugh.
It vanished before becoming one.
Pietro heard it anyway.
His expression brightened with immediate sibling malice.
Wanda pointed at the chalk line.
"Start."
He did.
The second approach felt different for the simple reason that now they were waiting for something.
Expectation contaminated observation.
Erikar disliked that.
The first step produced nothing.
The second too.
He watched Wanda's shoulders rather than the mark he could not see beneath her clothes.
No tension.
No hesitation.
Third step.
Nothing.
Fourth.
Her fingers twitched.
Red gathered at the base of one knuckle.
Barely visible.
Pietro's voice cut in immediately.
"No."
Wanda stopped.
The red disappeared.
"I didn't do that deliberately."
"I know."
"Then why are you looking at me like I broke a rule?"
"Because whether you meant to is another variable."
That quieted the objection.
Good.
Pietro was learning the shape of the problem quickly.
Not merely protecting his sister.
Controlling the room.
One variable at a time.
Wanda flexed her hand once.
"No power."
Pietro nodded. "Continue."
She stepped forward.
Erikar waited.
Nothing.
That was wrong.
Or rather, different.
On the first run the response had already begun before this point.
He checked his breathing.
Shoulder.
Mark.
Attention.
Had expecting the response altered the threshold?
Had the first activation changed the mark?
Had Wanda's involuntary gathering of power mattered despite being stopped?
Too many possible explanations.
She took another half step.
The pressure arrived.
Sharper than before but later.
Erikar spoke immediately.
"Now."
Wanda stopped at almost the same instant.
"Yes."
Pietro looked at the ground.
Not at either of them.
At the marks.
He walked sideways to compare her position against the chalk line.
His face tightened.
"Not the same place."
"No," Erikar said.
Wanda looked down.
"Farther."
"A little."
Pietro crouched and used a smaller piece of chalk to mark where the second response had begun.
Two pale lines now crossed the concrete.
Close.
Not identical.
He stood.
"Again?"
Erikar looked at Wanda.
She was already looking at him.
Neither answered immediately.
Pietro's expression hardened.
"No meaningful silences."
Wanda looked away first.
"Not yet."
Erikar agreed. "Back her out."
Pietro nodded.
Better.
They had enough for one variable.
Wanda retreated.
The pressure under Erikar's sternum decreased with every few steps, but not smoothly. For one pace it held. Then dropped more noticeably on the next. The strange second rhythm faded until only the original low House pressure remained.
Wanda stopped at the far line.
"Baseline."
Erikar checked himself.
"Close."
Pietro looked between them.
"Close is not baseline."
"No."
"Which is irritating."
"Yes."
"Good. At least we agree on something useful."
He rubbed at the second chalk mark with the edge of his boot but stopped before erasing it.
Erikar looked down the distance between himself and Wanda.
First activation here.
Second activation slightly farther in.
Separation lowered both.
That was evidence.
Not explanation.
Wanda crossed her arms tighter.
"So the bridge wasn't wrong."
Erikar understood what she meant.
"The machine identified a real response."
"It amplified it."
"Probably."
Pietro turned sharply.
Erikar corrected himself before the complaint arrived.
"We have evidence it amplified something. We do not have enough to define what."
Pietro lowered the finger he had already raised.
"I am becoming unnecessary."
"No danger of that," Wanda said.
He looked suspiciously pleased.
The yard wind strengthened, carrying river water, old oil, and the metallic smell of damp fencing.
Erikar studied the nearest chalk mark.
The problem had changed.
At the bridge, proximity had been one piece of a larger mechanism. Current, House residue, external machinery, pain, Wanda's power, his own mark. Too many variables imposed at once to know which one mattered most.
Here they had removed almost all of them.
No enemy.
No deliberate current.
No deliberate Chaos.
No touch.
No command from the House.
And still the mark had answered.
Twice.
That made proximity operationally relevant.
It did not make proximity causal.
A distinction worth preserving.
Wanda said, "You're doing it again."
Erikar looked up.
"What."
"Building the whole thing in your head instead of saying the part we need."
Pietro pointed at her. "That. Keep doing that."
She ignored him.
Erikar considered the question.
"The threshold moved."
"Yes."
"So distance isn't enough."
Her eyes narrowed slightly.
"Injury?"
"Possible."
"Recovery?"
"Possible."
Pietro added, "Attention."
Erikar looked at him.
Pietro shrugged. "First time you weren't expecting it. Second time all three of us were staring at the same patch of concrete like it owed us money."
Fair.
Wanda glanced toward the forklift shed.
"Residual House effect."
"Possible," Erikar said.
"That is four possibilities."
"More."
"I dislike you."
"Temporarily?"
"No."
Pietro looked between them.
"Excellent. We're returning to healthy communication."
Wanda dropped her arms.
"What was next."
Pietro turned toward the shed.
"Current."
He took two steps.
Erikar said, "Not tonight."
Pietro stopped.
Wanda looked at him.
Erikar continued.
"We have a response with one variable. Adding another before we understand the first only makes the next result less useful."
For a moment Pietro said nothing.
Then his head tilted.
Not disagreement.
Approval being carefully hidden.
Wanda looked from Erikar to the station.
"I thought you would want more data."
"I do."
"Then."
"Better data."
That ended it.
She gave one short nod.
Trust via method.
Nothing more complicated required.
Pietro walked to the forklift station anyway.
"Then I am shutting this ugly thing down completely before one of you changes your mind."
"The wall feed is already disconnected," Wanda said.
"I know."
He crouched beside the old battery unit.
The security light above him threw a thin shadow across the concrete.
Erikar watched without particular concern.
The mark had settled again.
His shoulder hurt.
Wanda remained at the far line.
Everything they had just established could be arranged into something useful.
Proximity produced response.
Retreat reduced it.
The threshold shifted.
No visible power required.
No contact required.
No large city pulse required.
That was enough for one night.
Perhaps more than enough.
Pietro pulled open the lower metal panel on the battery housing.
Stopped.
Erikar saw the change before he spoke.
The brother's posture lost its usual impatience.
Not fear.
Concentration.
He reached into the open compartment.
Moved one cable.
Then another.
Wanda noticed.
"What."
Pietro did not answer.
He leaned closer and wiped corrosion from one terminal with his thumb.
Erikar crossed neither line nor distance.
"What is it."
Pietro sat back on his heels.
"The output lead."
Wanda waited.
"What about it."
Pietro looked at the cable in his hand.
Then at the empty terminal inside the housing.
"It isn't connected."
The yard seemed to become quieter.
Erikar looked toward the station.
"The wall supply?"
"Not that."
Pietro stood slowly.
"The battery."
Wanda's face changed by almost nothing.
That was enough.
Pietro lifted the loose cable.
"This unit has been dead the entire time."
Erikar looked at the charger.
At the disconnected wall feed.
At the open battery housing.
At the terminal carrying no cable.
Then back across the yard at Wanda.
No deliberate current.
That they had known.
No current from the test apparatus.
That was different.
The yard's ordinary electrical background had remained exactly what it had been before Wanda moved. No surge. No added source. No machine completing the circuit.
Only the distance between them had changed.
Wanda said, "You're certain."
Pietro gave her a look.
Then he bent down, pulled the cable farther into the light, and showed them the corroded end.
"This hasn't been attached tonight. It probably hasn't been attached this year."
No one answered.
There was no useful joke for him to make.
No argument for Wanda to sharpen.
Nothing for Erikar to reduce into a smaller category without first accepting the larger one.
The bridge machine had not invented the line.
The city's electrical systems had not created it.
The House chamber had not needed to remain open.
Those things had forced the connection louder.
Made it violent.
Made it useful to enemies.
But here, in a dead yard beside a dead machine with no active current between them, Wanda had taken several ordinary steps across cracked concrete.
And the marks had answered each other anyway.
Erikar looked at the chalk lines again.
Two thresholds.
Not identical.
Both real.
The classification changed.
The circuit did not require someone else to close it.
It was already there.
Waiting to be made loud.
