Before Taylor could do anything, the door to the spice closet opened on its own, slamming against the shelves inside, bottles falling and smashing as they landed on the ground, the perfumed smell of different spices hitting Taylor's nose as she recoiled.

A figure barrelled out of the spice closet, sending Taylor stumbling backwards as her emerald eyes sharply watched as the figure moved awkwardly.

Only when it spoke, Taylor lowered the knife.

"Paul!" She exhaled sharply as she stuck the knife on the kitchen island, hurrying to his side as he's covered in a myriad of different spices that smelled strong enough it covered up the blood.

Bringing him to one of the seats, Taylor rushed to grab a wet rag, patting down the blood as it dribbled from wounds over Paul's face.

"What on earth happened? Taylor asks him as she held the wet rag over the gouges in his face.

Exhaling sharply, Paul, gritting his teeth in pain, tells her, "There is something in the walls!"

The cooks had every right to be afraid, as Paul struggled to tell Taylor as she tended to his wounds.

Long claw marks, spaced like a human hand, made Taylor question what exactly attacked Paul.

He couldn't describe it well, being it happened in the darkness of behind the walls, but he's certain that it's a person.

Regaling his story, Paul managed to describe how he found a hole bored from behind one of the bookcases in Arthur's study.

It wasn't big enough that someone could walk out of it, but how Paul managed to squeeze through it, it had to been someone capable of doing just that.

A good thing he has his father's healing capabilities, Paul thinks he might've broken a rib squeezing himself through.

It was claustrophobically cramped, with no fresh air coming through, got his coat caught on the nails more than once, but Paul ended up finding himself in the library.

There he found the culprit, whoever it was they're agile, and familiar with the layout enough they don't have a second guess.

Spooked them and when they saw him, well, Taylor can clearly see how it turned out.

"Oh, why didn't you say something sooner?" Taylor chided Paul for not saying anything sooner to her telepathically.

Paul admitted that he didn't want to scare her and the fact he couldn't find this somebody meant he would be giving her outdated information.

Anyhow, he found his way into the spice closet, so here he is, and as Taylor took care of him, his angel eyes glanced around.

… Arthur wasn't anywhere in the kitchen.

"Dear, where's Mr. Williams?" Paul turned his head towards her.

Blinking, her mind catching up to her, Taylor swore that Arthur was behind her when they heard Paul in the spice closet.

"Mr. Williams?" Taylor called out to him, but he didn't answer.

Instead, they heard crashing noises, alerting them something going on in the corridor outside the kitchen doors.

Jumping up, Paul walked in front of Taylor as he guided her outside the kitchen.

A potted plant had fallen from the wall adjacent to them.

Above, the lights flickered before turning off.

Keeping her close to him, Paul maneuvered around the darkened home, using his trusty Sonic Screwdriver as a light.

He kept Taylor calm by talking to her in her mind while trying to find their way around and find Arthur.

"How did they get inside the wall?" Taylor wondered how this individual managed to get inside the walls without anyone noticing until, now.

Thinking about it, Paul says that when he came down from the first floor, there was a way into the cellar through another hole leading down ward, so likely their culprit broke into the cellar somehow and found a way into the walls.

Paul has a simple plan, find Arthur, get the hell out of here, and go front here.

By then, the gouges in his face and back and his broken rib will heal.

The perks of being one-quarter Time Lord, these wounds won't have lasting effects on him unlike others who weren't fortunate.

He and Taylor were stopped as they heard noises coming from the dining room before they heard Arthur's shouting.

Rushing through the darkened corridor, the pair hurried to the dining room as they heard crashing noises and Arthur shouting at someone.

The two-doors were locked from the inside and Paul used his Sonic Screwdriver to force them unlocked.

Upon forcing their way through, they don't see anyone inside the dining room, but there's broken pottery, the chairs knocked over.

There had been a struggle and as they studied the scene, they caught sight of the lit fireplace.

"I felt heat when I was making my way through," Paul remembered as he turned his head towards Taylor, "they must've taken him through the wall!"

They didn't have enough time to figure out the motives of the perpetrator, Arthur needed their help.

God only knows if they'll rescue him in time.

There's only one location in the home they haven't gone through that the perpetrator could've taken Arthur — the cellar.

Why not through the front door, well, Paul didn't have any idea why, only that Arthur's their main priority.

Doubling back with Taylor from the dining room, he hurried through the darkness illuminated by his Sonic Screwdriver, towards the entrance into the cellar.

As they arrived, Paul was sure that the door was locked as the dining room doors, but it wasn't.

With ease the door gave, no sign of tampering, and he was sure Ethel would've locked it.

In the brief time that he knew her, Paul saw how much Ethel fretted about Arthur, that she wouldn't have allowed the cellar to be unlocked without her knowledge.

She'd be worried about her employer falling to his death accidentally going through the cellar door where there's steps leading down that she'd always checked the lock on the cellar whenever she finished her business.

The cooks were the same, they wouldn't want their employer accidentally killing himself, so they wouldn't want the cellar door unlocked, either.

As his mother taught him, Paul felt something in his gut, not the pain from the fight he undertook with the unknown perpetrator, but a feeling.

Something wasn't right and it'd be foolish if he ignored his instinct.

"Grace, return to the TARDIS," Paul tells Taylor, much to her shock, as she stood near the blue hue of the light from Paul's Sonic Screwdriver.

She shook her head as she admittedly says, "Wh-why?"

His angel eyes slowly moved towards the cellar door, Paul tells her, "It's a trap. I'm expected."

Shocked, Taylor tried to ask for more information, but Paul insisted that she hurry out of there.

He can handle himself.

"Liar!" Taylor showed displeasure as Paul insisted this, but he wouldn't relent, worried about her more than anything.

He wanted her to get back to the TARDIS and follow its instructions.

There's hesitation in Taylor's emerald eyes, but Paul coaxed her to flee while she still could.

Despite her hesitation, Taylor finally broke away from Paul's side, fleeing as quick as she could through the darkened corridor, while he returned to looking at the darkness awaiting him below.

Exhaling sharply, Paul put on a brave face as he began his descent below.

The steep steps barely creaked, there was no visible light sources, silence greeted him, and the only sound he heard were his two beating hearts.

His father warned him of the many traps' enemies may lay for him, sometimes psychological, sometimes physical, sometimes a bit of both, but depending on the enemy, the traps can be anywhere from a bug bite to something that remained with Paul until his natural conclusion.
