A man in a tight cream coloured vest and trench coat with an accurately tied pink plaid bow tie came bolting through the door, stumbling over his own footing.

The Doctor and Rose ran to the side to get out of Aziraphale's way, but Crowley stood steadily in the same position, directly in front of the door. His arms were spread out like an eagle, ready to catch the angel's weight.

"Look out!" the white-haired man squealed as he tripped and fumbled through the door into Crowley's warm embrace.

Aziraphale's weight proved too much for Crowley to handle once the angel knocked Crowley to the ground in one harsh blow.

The Doctor smashed his hand on the red button once again as the thick slab of metal fell steadily down to the ground.

"I see you literally fell for me huh," Crowley chuckled but the pressure on his stomach made it sound like a wheezing gasp.

"There's this thing! It was… Oh my goodness… I've never seen anything like it?!" Aziraphale's voice was coated heavily in panic. His chest rose and fell at a fast pace as his eyes searched frantically until they stopped on Crowley's.

"That… was a weeping angel," The Doctor interjected as he confidently shoved his sonic screwdriver back into the inside of his jacket.

Crowley expressed slight discomfort in his current position as Aziraphale acknowledged it and pushed himself into a standing position

"That did NOT look like an angel," Aziraphale pointed at the Doctor as he shook his head uncomfortably.

"No not an angel, a weeping angel. They are as old as the universe itself and can move faster than the blink of an eye," The Doctor prolonged his sentences dramatically while interlacing his arms across his chest.

"But it was stone!?" Aziraphale glanced at the doctor with a worried and confused expression painted across his frame.

"Their physical appearance is stone but they're one of the most dangerous things in all of creation," The Doctor spoke with his breath held at the back of his throat.

Suddenly, the sound of fists pounding on metal echoed through the room. Realisation struck them hard in the chest which caused everyone but the doctor to jump in freight.

Aziraphale turned to Crowley with his eyes wide in horror.

"Oh dear. It appears I may have made a booboo," Aziraphale commented as his head fell to the ground in embarrassment.

"What have you done this time angel. Don't tell me you're the one who released this 'what do you call it…' depressed angel. Cause that would be a new low, even for you," Crowley rolled his eyes and jumped again as another iron fist connected with the door.

"Ah, it's weeping," Rose interjected silently with her neck craned forward.

"What?" Crowley swung his head around to meet with Rose's maroon eyes.

"It's called a weeping angel," Rose said with a smug look on her face.

"Oh who CARES what it's called! Weeping, Depressed, same thing. What I would like to know is, how in all of creation will we maneuverer our way outta here? Any clever ideas?" Crowley's voice was forced into a higher resonance as he attempted to beat the noise of the alarms.

"Spaceman! You seem to be the brains around here. Got a plan?" Crowley waved his hands about as he faced the doctor and began to move, his boots causing the metal to vibrate with every step.

"Not unless you have a mirror on you," The Doctor joked as he shoved his bony hands into the left pocket of his trench coat.

He ruffled around in his pockets manically as if he were looking for a book in a library with a blindfold on.

He sighed heavily as he pulled his hand out and looked up to see the man in the lighter trench coat with his hand stretched out in front of him.

"Will this do?" The angel said with a tone which begged for acceptance, like a young child.

In his beefy palm rested a small circular object with a face of translucent reflection.

"It's perfect!" The Doctor glanced up at Aziraphale with child-like hope sparkling in his old eyes.

He grasped the mirror and stretched out his sleeve as he wiped it with the inside of his wrist.

The sirens grew louder and more intense as the sounds bounced off of their metallic surroundings like a handball on concrete.

"Now all I need to do is adjust the harmonic frequency so that it matches the angel's resonance," The Doctor smiled intelligently as he whipped out his sonic screwdriver once more and aimed it at the mirror in the centre of his palm.

The sonic came to life in several small bursts of blue light as the doctor held it upside down with his thumb stiffly placed on the bottom.

"And… Done," The Doctor said proudly as he held the mirror up to his face.

"Work of magic… Well science… But magic sounds cooler… See!" The Doctor rambled awkwardly and shoved the mirror into the blonde man's face.

"Why can I not see my reflection? Am I a ghost? Oh no don't tell me I've died and become a ghost!" Aziraphale exclaimed melodramatically.

"You're an angel Aziraphale. Not a ghost," Crowley rolled his eyes as he traced the indented patterns along the walls.

"Oh yeah. Forgot about that," Aziraphale smiled sheepishly whilst Rose examined the mirror she removed from the Doctor's care.

"So how does it work? I assume were going to use it to trap the weeping angel," Rose interrupted the silence as she handed the mirror to Crowley.

"Think of the universe like this. Everything emits some level of harmonic frequency and if you match their frequency with enough power, you can destroy it. A bit like how you can shatter a wine glass by singing," The Doctor unknowingly looked over at Crowley who was currently inspecting himself in the mirror, despite not being able to see his counterpart.

"So that's the reason why we can't see our reflection! Because you've tuned it into the angel's frequency! Oh, that's clever!" Rose exclaimed as Crowley handed the mirror back to The Doctor with a smirk.

"Clever's my middle name," The Doctor uttered as he held the mirror a metre in front of his chest; the reflective side facing the door.

"When I say go… Rose, you press the red button and get behind me as fast as you can," The Doctor directed and confirmed it with a single nod.

Crowley and Aziraphale snuck behind the Doctors skinny frame as Aziraphale reached for Crowley's hand with a petrified expression on his face.

"Ready?" The Doctor stared wide eyed at Rose.

"Go!"
