As soon as they stepped foot int eh parking lot of Buckingham Palace, Dean broke into a sprint, Rose groaning as she jogged to keep up.

"You know!" she panted as she caught up with him, "I don't usually do… this kind of …. running!" As soon as she caught up with him, he was kneeling next to his car, the door open. The yellow paint spelling out the damned words was still there, dried and flaking. Where the Doctor had licked the door was dry as well, leaving no trace of him actually having made contact with it.

"No!" he muttered harshly, banging his fist against the door, "fucking damn it!"

"What is it? What's wrong?" Rose asked, panic rising in her voice. He was kneeling not eh ground, hands groping the driver's seat frantically.

"Sammy?!" he called, "Sammy!?" Rose cocked an eyebrow.

"What are you going on about?" she asked, peering into the car. No one was sitting in any of the seats. Jack was with the doctor, and K-9 was with them as well.

"Sam is gone!" he said, nearly yelling, "Sam is gone! He's gone!"

"Okay, okay!" Rose shouted at him, silencing him instantly, "it's gonna be alright, we'll find him!" She rubbed his arm, trying to console him.

"We shouldn't have left him!" Dean mumbled under his breath, "we shouldn't have…."

"Dean, listen to me," Rose said soothingly, "he probably came to and is wandering around looking for us, alright? He's a big boy now, he'll be able to take car of himself for a while." She felt as if she were dealing with a child who had lost his security blanket. Instead of a blanket it's his brother, she thought, slamming the car door shut, "How about we get whatever supplies we need and go back inside, alright? Jack and the Doctor are waiting!" Nodding, Dean opened the trunk, digging his ahdns into a massive pile of weapons. Rose gasped- he probably had a bigger arsenal in the trunk of his car then the Queen of England did inside the castle!

"Alright," Dean said gruffly, "let's go." He shoved a large bag of salt at her, motioning for her to follow. Struggling, she jogged after him, trying her best not to spill any of the salt out of the white and blue burlap sack.

"Is this really necessary?" she asked.

"Trust me," Dean said, "it is." Rose shrugged, following hims she open the doors tot eh palace, walking straight past the security guards like they had before- tank fully, they paid the to no mind, going about their jobs as they usually did: keeping nosy tourists at bay from touching priceless artifacts. Turning the corner, they expected to find the Doctor and Jack waiting patiently, but to their surprise there was no one there.

"Where did they go?" Dean said, feeling the panic come back. Rose shrugged, jutting her chin down the hall.

"They probably went down there, no?" she suggested. Dean shrugged, answering, "Let's go then, Blondie!" Rose rolled her eyes as they started running again.

"If we keep running I'm going to need to buy myself a pair of sneakers!" Rose commented. Dean rolled his eyes at her- girls could be so demanding sometimes!

"Complain when we get there, alright?" he said, muscles straining as he ran- how long was this damn hallway?! Rose suddenly skidded to a stop, falling forward as she did so, sing the bag to break her fall. Dean nearly crashed into a wall as he tried turning around.

"You okay?" he asked, leaning down and helping her up. Nodding, she dusted herself off, flecks of salt and dirt falling to the floor.

"I think so," she said, "I mean, the salt did break my fall…"

"Okay, well, as long as you're not broken in any way shape or form, let's keep going," Dean said, picking up the sack himself, cradling it in his left arm as if it were a precious baby. As Dean took the first few steps down the hall, Rose pointed past him, eyes wide,a smile on her face.

"Look!" she exclaimed, shaking his shoulder, "over there!"

"I kin dog have a sack of salt in my way!" Dean complained, trying his best to peek around it. Rose scowled, knocking the sack to the floor.

"Now can you see it?" she asked incredulously.

"Son of a bitch…." Dean muttered, green eyes wide as he and Rose watched it appear… no, materialize out of thin air, making a rough whistling type noise as it did so. Grabbing Dean's arm, she dragged him toward it, reaching for the handle on the blue wooden door, her fingers nearly able to touch it….

There was a sudden jerk as dean pulled back, shaking his head.

"What is it?" Rose asked.

"That isn't possible…" he muttered, trailing off.

"It's not impossible, it's the TARDIS," Rose said, "now come on! If the TARDIS is here that means Jack and the Doctor are inside!" Deans hook his head.

"But Sammy…" Dean pointed out, "where is he? We have to find him!"

"And the TARDS has a GPS that can detect where any person in the world is," Rose explained with a nod of her head, "so we can use that to find him! Now come on!"

"But how can four people fit inside a phone box?" Dean asked, scratching his chin. The wooden box itself seemed to be beaten up, certain spots of the blue paint warped and faded. A sign on the door said "POLICE BOX," the blue words chipped and almost unreadable. Rose grinned, pulling open the door and ushering him inside.

"Well?" she asked, watching as his already widened eyes went wider, looking like saucers, ready to bug out of his sockets.

"It's…." he began. What was it? Strange, for one thing, he thought, then it struck him: if the Doctor was possessed and had pushed her out of the very machine they were standing in, what if the possessed alien was still in here? Carefully, he slipped an Angel Blade out of his pocket, flicking it open. There was a metallic shiny as it opened, the blade newly sharpened, ready to bite.

"Dean?" Rose asked, watching as he then took the salt and began lining the walls with it, careful to get it into every nook and cranny.

"Rose whatever you do do not move out of the salt outline, you got it?" he commanded, eyes narrowing as he finished.

"What do you mean?" Rose asked, "I don't understand-"

"Just do as I say!" Dean cut her off. Nodding, she shut her mouth, biting her lip nervously. As soon as he finished with the salt, he held the blade at his waist, knuckles turning white from gripping it so tightly. Rose noticed a vein in his neck popping out, looking as if ti was going to burst at any minute. That's when they heard it:

"Who the hell are you?" came a voice, somewhat gravelly, low, and definitely British.

"Captain Jack Harkness," Jack's voice sounded, "and what the fuck are you doing?!"

"JACK!" screamed the Doctor suddenly, making the two jump, "GET AWAY FROM HIM!" There was a crash, glassy shattering and dean was racing towards the sound.

"Dean?!" Rose shrieks after him, unsure of whether she should follow.

"Stay put!" Dean shouted back, his voice echoing down the hall, leaving Rose to stand in the salt outline with the console for company, nervously awaiting what was down the hall.
