It was not long before Clara, decided the TARIDS was haunted. There were moments when she stood alone in the console room – or at least she believed she was alone- when she felt an invisible presence looking down at her. She would feel a brush against her arm, a sudden breeze against her face that is created when one quickly walks by. The presence was dominating which made her look over her shoulder more often than she could count. Ghosts was never something Clara quite believed in, but now with quivering chills scrambling up and down her spine, she began to believe in something else altogether.

"Do you believe there are ghosts, Doctor?" Clara asked as casually as she could manage without slipping the fear she felt into her words.

"Eh?"

"Ghosts...real ghosts. Not some alien that looks like one, or something that pretends to being one... a real haunting spooky ghost?"

The Doctor looked up from under the console and gave her a calculating look. "Don't know," he admitted finally, "Never seen one, so I guess no," he scratched his head in thought as if the question was more complex than Clara had intended.

"Really? Huh," Clara shrugged and leaned against the railing, "have you ever thought that...by chance...the TARDIS would be...could be...er...well..."

"Well what?"

"...haunted?" she bit out in hast. The Doctor guffawed at her, "Well if there are ghosts, I don't really know why they would want to 'haunt' a TARDIS." He shook his head still laughing coming up to stand beside her, but he suddenly stopped, noticing Clara's silence.

"Why? Is the old girl giving you a hard time?" he gestured toward the counsel, patting the metal surface lightly.

"No, no," Clara bit her lip in distraction, "its just for the past few days, I've noticed something has not been quite right. Like there is someone else standing in this room with us, but neither of us can see...it. I feel like I'm being watched all the time, sometimes I even feel a hand on my shoulder or someone passing by me. Have you not felt it? There is something here...something big, but it's like hiding behind a curtain of some kind."

"Very interesting," the Doctor murmured after some time. He glanced consciously around the console room. "Come out wherever you are!" he grinned excitedly.

"So you believe someone could be hiding here?" Clara asked uncertain she should be relieved.

"Wouldn't be the first time," he replied offhandedly. There was silence between them, the only sound was of the TARDIS humming hauntingly, and neither noticed the figure standing stolidly in the shadow.

"Doctor," Clara whispered, "I keep seeing this figure, well I can't see it exactly, but when I think I see someone standing just behind me, it disappears before I even know for certain it was there. Maybe I"m just imagining it...but that feeling is always there."

Slowly, he pulls the glowing screwdriver from his coat and swipes it through the air.

"There is no readings," he whispers in reply, but feels a a presence standing behind him.

"You feel it don't you?" Clara murmurs excitedly grasping his hand.

"Is it that feeling, Clara, that someone, or rather something, is standing right behind you, but you know for certain nothing could possibly be there because there is nothing there, but you feel it all the same?"

"At the moment, very much yes," Clara mutters softly. The room had become suddenly darker, as if reflecting the fear that pulsed through Clara's veins. She felt the something breathing down her neck and felt her heart leap in anticipation. They both had their backs turned from the opening door of the TARDIS, and felt the presence behind them grow stronger with every breath they took.

"When I count to three," his voice barely reached her ears, "we both turn around." She nodded her head in acknowledgment.

"Ok," she swallowed.

"One."

He grasped her hand.

"Two."

She held her breath.

"Three!"

They both whirled around facing the ominous monster, both ready to take on what ever threatened them. Neither was sure what they expected to see, but the vast empty space at their backs was not one of them. They both stood in silence unsure what to say to the other. After a long expectant pause, Clara let out a loud snort, then clenched her sides with her fists as she doubled over in peels of laughter.

"If you could have seen your face!" she rasped between gulps of air.

"Mine?" the Doctor sounded aghast, "you should have seen yours! One would think you expected the whole Judoon army to explode through the walls!"

They stood and laughed with each other, the mood lifting and the moment of fear forgotten until the lights of the TARIDS went out with a faint click as if someone had pulled the switch. The only light was the glowing blue of the Time Energy. Their laughter cut short and stuck in their throat.

"Who's there?" the Doctor called.

"Doctor..." Clara whispers urgently tugging violently at his sleeve.

"Come out and show yourself!" He calls out ignoring Clara.

"Doctor I don't..."

"You can't hide forever, you'll have to come out sometime..."

"Doctor!" Clara shouts, there is fear in her voice.

"What?" He can barely see her, but her face glows slightly in the blue light, odd shadows stretched across the pretty face. Her eyes held his without blinking her voice barely reaching his ears.

"Its here." Clara's desperate whisper seemed to echo off the walls.

The certainty in her voice made him glance widely about the room, now assured of the unwelcome presence. There is a sound deep within the TARDIS that howls and rattles the structure of the old machine. The Doctor and Clara clasp their ears as the sound grows louder and louder until they fall on their knees. The floor beneath them trembles and both fear the metal structure would collapse beneath them. Then, with a gasp of Clara's breath, the sound vanishes and the silence that follows is more than terrible. The lights flicked about them then burst into full flame.

Slowly, both raise their heads and glanced about them, reassuring themselves that they were alone. They stood clumsily to their feet, hands reaching for each other as they pulled themselves up.

"Wh-what was that?" Clara gasped breathlessly.

Without a word the Doctor leapt into action as if he had never been huddled on the floor. He ran around the counsel in small leaps and jumps, pulling leavers and pushing glowing buttons. So consumed with his work he nearly missed the startled gasp. He was about to ask what the matter was without looking to inspect his disturbed companion, when her demanding voice, "Doctor look!" jolts him to glance up at her.

Clara had her back turned from him so she could not see the blanched, startled look that bled across his face. For there sketched in immense, black, bold words that dripped black stains eerily to the floor, made his head spin and breath shallow.

"Bad Wolf." Clara's voice echos in the TARDIS and for a long time there was not a words between them.
