*A/N: WhouffleSmolemanForever: If anything, it's more Whouffle-ish. I don't do cross-fandom-shipping, and I try not to break canon if I can help it! Oh, and also, it's 11th Doctor, not 12, just so y'all know. Hope y'all like this one! -KM

The Winchester brothers stared.

Sam leaned in.

"Phone box?" He whispered.

"Shut your pie hole!" Dean hissed. His eyes never left the woman.

She crossed her arms and surveyed them dubiously. "Well? Who are you? Was the Doctor with you?" She huffed and marched right past them to the door. "Well if he wasn't then—"

"DON'T!" The brothers cried in unison.

She whirled on them. "All right, why not?"

Dean considered lying, but somehow, given the context, he wondered why he would bother. "Um, would you believe killer angel statues?"

She gasped and her brown eyes flew wide again. "Weeping Angels? You mean he was right?" She made for the door again. "We have to get out there," she said. "If they catch him there's no way we could rescue him!"

Dean stared at her. "Who the hell are you?"

She smiled grimly. "I'm Clara Oswald, companion to the Doctor; I'm the Impossible Girl, and I need to find him!" She shoved the door open, and the boys winced—but nothing happened.

Clara whirled back to look at the monitor. They had only traveled about a year into the future, but the town was already deserted. The brothers followed her out, staring at the overgrown hedges that were once the church walls, the silent, empty land that only minutes ago had held a busy little town.

"What the hell happened?" Sam gasped.

"The Angels must have taken everybody," Clara answered. She looked at the two of them. "And you are—"

The brothers automatically pulled out the badges, but Clara shook her head. "You realize I can tell those are fake, right?" The skepticism returned. "Who are you, and what would you need fake badges for?"

Dean sighed. "Dean Winchester, and this is my brother Sam."

"Winchester!" Clara's face lit up. "I know that name! It—wait," she bit her lip. "What year is it?"

Dean arched his eyebrow. "Uhh, 2013?"

"Hmm, it would be in the past, then. Do you have a relative named Henry?"

Sam choked. "You met Henry?"

Dean glanced back at the innocuous blue telephone booth that looked nothing like the space-age command deck they had seen inside. "What the hell is that thing?"

Clara smiled. "It's called a TARDIS, but you might think of it as a sort of time-and-space machine."

"A time machine?" Dean squawked.

"Mm-hm; and space. Basically any relative dimension."

Sam was feeling the same way he did when they first found the Men of Letters bunker. "How big is it on the inside, anyway?"

Clara shrugged. "I've given up trying to think about it; it's practically infinite."

"But here on the outside it looks like—"

Clara nodded before Dean finished. "Yeah, a phone box. It's funny how few people actually ask questions about that." She chuckled. "You wouldn't believe how many times the Doctor has tricked the police into thinking he's coming in here to arrest himself—"

"What doctor?" Sam asked.

Clara blinked. "He's just The Doctor," she said with a shrug. "He's actually a Time Lord from another planet, but he defends Earth from all sorts of bad situations..." She smiled wistfully, "and the incredible thing is that nobody is ever the wiser."

The brothers shared another glance. "Yeah, we know the feeling. So... What can you tell us about the things that were chasing us outside?"

She gestured to a row of park benches still standing. They sat and she spoke. "Okay, the Weeping Angels are a sort of alien that exists in a quantum dimension."

Dean felt like he was back in... Whatever last grade of school he attended. "Quantum?"

"Oh I get it," said Stanford Sam, "so their space-time reality is different than ours, which is why they appear to move so fast-but only if they're outside anyone else's perception."

Clara grinned. "Exactly; they can't move when they're being watched, you see, even if it's one Angel watching another."

Dean hated feeling like the dumb one in the room. "Then how do you explain the attacks, and those same people showing up thirty years in the past?"

Clara looked grim. "That's how they feed, on life energy. They remove people from the present life, and then all of the future energy fuels the Angels as they live out the rest of their years in the past."

Sam could practically see Dean's brain folding on itself trying to work this out. His brother made a fantastic Hunter because of his precise, linear thinking.

"Okay, Dean, let me help with a little math," he said. "Say our guy Stan was thirty years old when the Angels took him."

Dean nodded, "Okay."

"So let's say Stan lives till he's eighty. That gives him fifty more years after his disappearance, that he should have lived here in the present."

Dean hesitated a few minutes. "Okay," he finally nodded.

"So if the Angels had brought thirty-year-old Stan eighty years in the past, that would give them fifty years of energy, plus more if he lives past eighty, and Stan dies... roughly thirty years before today."

Clara smiled approvingly at Sam. "Look at you, sorting it out! You must be really smart."

Meanwhile, Dean worked the idea over in his head and nodded. "Yep, now I got it. So how do we stop these sons of bitches?"

Clara shrugged. "That's what the Doctor was going to tell me, and then an alarm went off and the TARDIS started moving." She sighed.

Sam looked around. "So where are we now?"

Clara bobbed her head. "Same place, different time. This is what the year 2014 looks like because we haven't stopped the Angels in 2013 yet."

Dean stared at the young Brit for five seconds. "Screw this!" He snapped, and turned back toward the blue time machine.

With a steady whooshing groan, it slowly blinked out of existence. By the time he reached out to touch it, the box faded for the last time and did not reappear.

"Dean!" Sam yelled reproachfully as he ran back. "What the hell did you do?"

"Nothing!" Dean snapped.

Clara intervened. "He's right, Sam; it's not Dean's fault. The TARDIS sometimes disappears on its own." She squinted at the older brother. "Are you sure it's not invisible?"

Dean walked forward and waved his arms. "Yeah, it's gone," he confirmed.

Sam threw up his hands. "Great! So now we're stranded here, with no idea—"

"Now hang on a minute," Clara reassured him. "The TARDIS wouldn't leave us here without good reason. The Doctor probably found the spot we left and called it back. He'll look at the logs and figure out where we went. He might even be here within minutes."

Sam, Dean, and Clara stood around the space once occupied by the TARDIS. They waited several minutes. Nothing moved.

"Well, this has been a complete waste of time!" Dean grumbled sarcastically.

"We'll be all right," said Clara, "there's no need to panic."

"I'm not panicking!" Dean snapped, turning away. Two paces later, he faced Clara and his brother again. "Okay yeah, I'm panicking a little—are you freaking kidding me? We just freaking TIME TRAVELED!"

"Dean," Sam caught his brother's shoulder. "We can figure this out."

Dean shrugged off the hand and stalked away. "Yeah, well we'd better!"

Sam caught a worried expression on Clara's face. "What is it?" He asked.

"Another reason the TARDIS might have left," she began slowly, "is that it detected danger."

"Danger?" Sam didn't like the chill that came with that word. "Like what kind of danger?"

"The energy the TARDIS possesses, the reason it's able to travel inter-dimensionally, is—"

"Lemme guess," Sam winced, "quantum energy?"

Clara nodded, "That's why they've been after the Doctor and the TARDIS for years. He's practically immortal, and with the TARDIS..." Her voice trailed off.

"They'd feed off of him for years," Sam finished.

"Who knows what the Angels would be capable of, with a virtually infinite power source?"

Sam watched his brother disappear down the road through town. "So if the TARDIS radar got spooked and transported away—" he looked back at her.

Clara nodded, confirming what they feared. "They're here."

Sam turned to call for Dean, but his brother had disappeared down a side street.

"Dammit, I'll go find him," he groaned.

"Be careful!" Clara warned.

Sam had to chuckle and roll his eyes. Between the two of them, Sam was the least likely to ignore that advice.

Up ahead, Dean had wandered into the morgue where they had found out about Stan and the time discrepancy. Would any sort of files exist if quantum alien things had reduced the area to a ghost town?

Dean hit a few keys, but the computer wouldn't even start up. He turned to the filing cabinet behind the desk—

And the hairs on the back of his neck rose. He whirled back around as Sam raised his hands defensively.

"Whoa, take it easy," said Sam. "It's just me."

"Dammit, Sammy," Dean shivered, "don't scare me like that!"

Sam frowned. "What are you doing?"

Dean shrugged. "I'm just looking around, seeing if anything changed from... Last time we were here."

Sam nodded, "Dean, I really don't think this is a good idea. Clara said that—"

"You know what?" Dean jabbed a finger at his brother. "I don't give a crap what that chick says! The whole thing is just mumbo-jumbo crazy talk!" He moved deeper into the corridors, back to the operating rooms. Sam followed out of necessity as Dean kept talking.

"It's you and me, Sammy; we're going to work together and figure this thing out, Winchester style—oh jeez!"

Sam darted forward as Dean screamed.

"What, what is it?"

Dean turned around with a smirk on his face. In his hands he clutched a length of metal piping, which he had grabbed in his fright. "Oh, just one of those angel statues freaked me ou—" his smirk vanished as he remembered the singular quality of those particular "statues."

"Sonofabitch!"

Sure enough, by the time Dean turned back around, the Angel was gone. Dean glared at Sam accusingly, but the younger Winchester shrugged. "It's what I've been trying to tell you. We think they're still here."

Just then, they heard Clara scream.

"Sonofabitch!" Dean yelled again as they ran back down the street.

Back at the original landing site, Clara was rooted to the spot, staring at the Angel reaching toward her, even as her smarting eyes were beginning to tear. Dean and Sam ran up, and she finally allowed her eyes to blink—only to see a second Angel appear behind the brothers!

"Dean, look out!" She cried.

Dean whirled around and swung the pipe, but the Angel merely quantum-leaped to another position and Dean swung at empty air.

"Don't let them touch you!" Clara warned.

Sam kept his eyes fixed on the Angel, no matter how badly he wanted to help his brother.

Just then, a familiar whooshing groan filled the air.

"It's the TARDIS!" cried Clara.

Sam glanced to his left and saw Clara there. He felt Dean at his back.

"I can see it, fellas," Dean said.

"I've got an Angel on me," Clara said.

"Same here," said Sam. "Okay, we all have to go together if we are going to make it." His eyes were burning, by Sam knew how dangerous it would be to look away now.

"Okay, here's how it's going to be," said Dean. "On the count of three, I'll grab Clara, and Clara, you grab Sam, and whatever you do, don't stop running till we're inside, okay?"

Sam gulped. "Got it."

"One... Two... Three!"

A half-second later, Sam felt Clara grab his hand.

"Run, you clever boy!" She cried, and Sam half-ran as she dragged him.

He ran blindly, knowing that every step would bring the Angels leaping closer. He ran so fast that the blue door was in front of him before he realized it, and the blue trim under the word "ICE" smacked him in the face before he could duck.

Dean slammed the door shut only moments before the entire machine began to rock and shake violently. The motor whooshed and whirled, and the dials on the ceiling spun, but it didn't seem to do much good. Finally, the shaking stopped, but the trio still could not relax. Every ear strained, listening for the sound of Angels nearby. Then—

Knock-knock.

Knock-knock.

Knock-knock.
