The underground chamber smelled faintly of rust, old incense, and something sweeter underneath.

Blood.

Not fresh enough to belong there naturally.

Fresh enough that Lucien noticed it immediately.

He stood near the partially opened iron gate while Seraphina continued examining the carved Church seals along the walls, her flashlight beam moving slowly across faded scripture and silver-lined symbols.

“You’ve seen these before,” he said.

It wasn’t really a question.

Seraphina crouched beside one of the lower markings without looking back at him. “Restricted archive material.”

“Your Order trains children using containment doctrine?”

“They train us using whatever keeps us alive.”

Lucien leaned one shoulder lightly against the stone archway behind him.

“That sounds exhausting.”

“It was meant to.”

The answer came automatically.

Too automatically.

She realized that a second too late.

Because when she finally glanced back toward him, something about his expression had changed slightly.

Not pity.

Lucien never looked like someone who wasted energy pitying people.

But there was recognition there now.

The unpleasant kind.

The kind shared between survivors who noticed familiar damage in each other.

Seraphina turned away before the thought settled too deeply.

The chamber had grown colder the longer they remained underground. Moisture dripped steadily from the ceiling somewhere beyond the tunnel corridors while distant pipes groaned faintly beneath the city streets overhead.

She focused on the symbols instead.

Practical things.

Measurable things.

Not the vampire standing behind her.

Unfortunately, that became difficult the moment dizziness hit.

It arrived suddenly enough to blur her vision for half a second.

Seraphina braced one hand against the wall immediately.

Lucien straightened at once.

“You’re getting worse.”

“I’m fine.”

“You keep saying that while actively bleeding on historical architecture.”

Only then did she notice the blood.

A thin line had slipped beneath the edge of her sleeve where the bite wound reopened under strain. Dark red against pale skin.

Not much.

Barely noticeable, honestly.

But the effect on Lucien was immediate.

Silence settled across the chamber.

Not empty silence.

The kind that sharpened.

Seraphina looked up instinctively.

Lucien had gone very still.

His gaze fixed on the blood running slowly down her wrist.

Not dramatic.

Not monstrous.

Which somehow made it worse.

Because she could actually see the exact moment his attention shifted from conversation to instinct.

His pupils darkened slightly.

His jaw tightened once.

The lantern in his hand lowered a fraction without him seeming aware of it.

And for the first time since meeting him—

Seraphina looked at Lucien and remembered very clearly that he was not human.

The realization moved through her slowly.

Not fear exactly.

More like standing too close to the edge of something deep enough to kill you before you heard the fall.

Lucien looked away first.

Toward the iron gate.

Toward literally anything else.

But the movement came half a second too late.

He’d already smelled it.

Seraphina slowly straightened from the wall.

“You reacted.”

Lucien’s voice remained calm when he answered.

“Yes.”

“That much blood shouldn’t matter.”

“It doesn’t.”

“That sounded dishonest.”

A faint, humorless smile touched his mouth briefly.

“You’re learning.”

The wound burned again.

Sharper now.

Seraphina reached automatically toward her sleeve to cover it, but Lucien noticed the movement immediately.

“Don’t.”

She frowned.

“Don’t what?”

“Hide it.”

That should not have sounded as intimate as it did underground in the dark.

Annoyed by her own reaction, Seraphina folded her arms instead.

“You’re staring.”

“I’m trying not to.”

The honesty caught her off guard.

Lucien exhaled slowly through his nose before setting the lantern down atop one of the abandoned plague tables nearby.

When he spoke again, his voice had gone quieter.

“Most vampires would’ve attacked you already.”

“Comforting.”

“I wasn’t trying to comfort you.”

“No,” she said dryly. “I noticed.”

Another drop of blood slid down her wrist.

Lucien’s eyes followed it involuntarily.

There it is again.

That loss of control.

Small.

Brief.

But real.

And strangely enough, Seraphina trusted that more than she trusted his composure.

Because at least instinct couldn’t lie politely.

“You said those creatures upstairs were adapting,” she said carefully. “Adapting to what?”

Lucien dragged his attention away from the blood with visible effort.

“The Church spent centuries studying vampire physiology.”

“And?”

“And your bloodline became part of that research eventually.”

The chamber suddenly felt even colder.

Seraphina’s expression hardened. “Explain.”

Lucien remained quiet for several seconds.

Long enough that she almost repeated the demand.

Then finally:

“The Van Helsing bloodline doesn’t smell human to vampires.”

Her pulse slowed.

“What does that mean?”

“It means your ancestors altered themselves.”

“That’s impossible.”

“You say that constantly for someone standing inside a plague crypt built to imprison artificial monsters.”

She hated that he had a point.

Lucien stepped closer then.

Not aggressively.

Carefully.

Like approaching something capable of spooking.

The movement should’ve triggered immediate defensive instinct.

Instead, Seraphina found herself watching the details.

The rain still drying slowly along the collar of his coat.

The faint silver scar disappearing beneath his throat.

The exhaustion hidden behind all that composure.

He stopped close enough now that she could feel the cold radiating from him.

Not metaphorical cold.

Actual temperature.

Dead things did not carry body heat properly.

Lucien’s gaze lowered once more toward the blood on her wrist.

This time he spoke almost absently.

“Your blood smells wrong.”

“Wrong how?”

His eyes lifted back to hers slowly.

“Like memory.”

The answer unsettled her more than she expected.

Before she could respond, Lucien reached toward her injured arm.

Not grabbing.

Asking silently.

Seraphina hesitated.

Every instinct she possessed screamed not to allow this.

But another part of her—the exhausted, curious, dangerously human part—wanted to know what would happen if she stopped treating every moment like a battlefield.

Slowly, she held out her wrist.

Lucien touched her carefully enough that the gesture almost felt deliberate in its restraint.

His fingers wrapped lightly around her arm.

Cold.

God, he was cold.

His thumb brushed once beneath the edge of the reopened wound.

The reaction hit him immediately.

Seraphina saw it happen in real time.

His breathing stopped.

Not slowed.

Stopped.

The chamber went completely silent except for dripping water somewhere deep underground.

Lucien’s eyes darkened sharply.

Not red.

Not yet.

But close.

His grip tightened involuntarily around her wrist.

Every predator instinct in her body woke up at once.

“Lucien.”

He didn’t answer.

His attention remained fixed entirely on the pulse beneath her skin.

On the blood.

On her.

And suddenly she understood something terrifying:

he was losing control quietly.

The worst kind.

Not frenzy.

Not violence.

Need.

Lucien lowered his head slightly before catching himself halfway through the movement.

His jaw clenched hard enough to visibly tense beneath pale skin.

For one dangerous second, Seraphina thought he might actually bite her.

Not because he wanted to hurt her.

Because some older part of him wanted her close enough to try.

Then Lucien released her abruptly and stepped backward so quickly the lantern nearly tipped sideways off the table.

Distance.

He needed distance.

Seraphina’s heart was beating too fast now, though she refused to examine why.

Lucien turned away completely, one hand braced hard against the ancient stone wall beside him.

When he finally spoke again, his voice sounded rougher than before.

“You should bandage that.”

She stared at his back for a moment.

At the tension still locked visibly through his shoulders.

Then, quietly:

“You stopped yourself.”

Lucien laughed once under his breath.

Not amused.

Just tired.

“Barely.”
