A/N: Hello loyal readers! Thanks for all of your feedback on where to send the Winchesters next, and for now I've picked the suggestion of Boredsherlock: they should go on an adventure to find the perfect pie. For now my writing might be a bit sloppy because I've got a sprained wrist and a concussion - don't worry, it was just me being stupid - and I'll probably make a shitload of mistakes. Please inform me of these if you see any so I can go back and edit my work for your enjoyment :)

Dean turned to Sam and gave him a smirk and a glance before looking back at the Doctor. "You can travel through all of time and space?" he said with a chuckle. "Then I wanna find the perfect pie." the man announced. Sam nodded before doing a double-take at his brother with confusion. "Wait, what?" he demanded. Dean shrugged. "I really, really like pie, and we've got all of time and space to find the perfect one."
The Doctor looked doubtful and leaned on the console of his magnificent TARDIS, a hand fingering through his lush hair. "Well, I know this pie shop in west Slorfax that is known for its excellent pie..." he said doubtfully. Dean shook his head and put a hand on the handrail, laughing insincerely. "No, I don't think you understand. I don't want 'excellent pie' from S'morecracks, I want the best. Pie. Ever." he emphasized. The Doctor bit his lip and Sam put a hand on Dean's shoulder. "He's just kidding. You don't actually have to scour the Universe for the perfect pie. Wherever is fine - as long as it's not the Wild West or Gandhi." the tall one laughed uneasily. Dean turned his head to look at Sam over his shoulder, growling. "If you stop me from getting the best pie in the Universe, I will shoot you and burn your bones." he threatened icily. Sam took his hand off of Dean's shoulder instantaneously and threw a helpless shrug at the Doctor, who reached behind him to scratch the back of his neck thoughtfully. "Well, I could ask around and see if anyone's heard of some legend or summat about the 'best pie in the Universe..." he said before turning to the controls and putting the TARDIS into flight. Dean nodded enthusiastically, his eyes bright, and grinned boyishly at Sam. "He's going to take us in a spaceship to find the best pie in the whole of time and space. How cool is that?"
"Yeah. Hell of a last adventure."
"I might just have to steal this thing!" Dean joked. Suddenly, a tremor went through the TARDIS, the lights flickered, and the big circular thing in the middle - the 'time rotor', as the Doctor had called it - began to make unnerving grinding and groaning noises. "Oh, stop that!" the Doctor yelled up at it, smacking the rotor with the flat of his hand. "That's very rude! Stop it, girl!" the Time Lord shouted, smacking the rotor again. The thing almost instantly recovered and groaned as if in reply. "I dunno what the thick homo-sapiens said to you, but I'll make sure I talk to them about it, alright? You don't need to be acting all fussy! You're nearly a thousand years old - you need to start acting like it!" the Doctor shouted. He stood in tense silence for a moment before lovingly stroking bits on the console, almost as if he was sorry, and then turned to Dean and Sam. "She doesn't like you, Dean." he announced. Dean rolled his eyes and laughed, trying to get something from Sam, but all he received was a shrug and a grimace. "What? You did joke about stealing her."
"Oh, you're calling it a her now?"
"That's what the Doctor does. If this thing is alive, I want to stay on its good side."
"Machines don't have 'good sides'." he scoffed. The TARDIS gave another angry shiver again, almost throwing the three of them off of their balance, and Dean looked up around him angrily, finally giving in. "Alright, alright! I'm sorry, okay?" he shouted. The TARDIS steadied herself, and the Doctor smiled winningly at Dean and Sam. "See? Easy enough! You've just got to be nice, and she'll be nice back. I mean, I can excuse the weeks when she's menstruating - "
"Wait, what?"
"Y'know, that thing that happens to women every month or so? Yes, the TARDIS menstruates. Almost every species in the Universe menstruates. Wonderful process, menstruation. Oh, I love it. I mean, a body pre-preparing to carry a child? Happens to most every being that can carry children. Which reminds me... Jack can get pregnant... I feel like I ought to ask him if he can menstruate." the Doctor said ponderously. Sam cleared his throat, averting his eyes. "I think you're rabbit-trailing." he mumbled. The Doctor made a surprised face. "Am I?"
"Just a little bit."
"Oh, sorry 'bout that."
"Uh, who the hell is Jack?" Dean demanded. The Doctor scratched the back of his neck with a hand and frowned. "An old friend. He's not been around for... oh, simply forever. But that's not important. What is important is getting Dean the Universe's most perfect pie!" he said excitedly, jumping to the TARDIS' console and pulling levers, pushing buttons, and occasionally hitting something with the flat of his hand or a rubber mallet he kept dangling off the console. Dean and Sam held on for dear life as the TARDIS completed its rickety, bumpy travel through the Time Vortex, and then landed with a thud. The Doctor peered at the monitor hanging off of the time rotor and frowned. "That's not right..." he mumbled. Sam was immediately at his side, trying to decipher the strange circles on the screen that must've been some sort of alien language. "What?" he demanded worriedly. "What's wrong?"
"Well, nothing too bad. I mean, the TARDIS isn't gonna blow up, so that's a relief."
"Then what's wrong?"
"Well, we're not in the 51st century. The TARDIS must've jumped a time track and then I guess the monitor expired, because it's not showing me anything I can use. I'll need to get on this pronto. But before that, how's about we go exploring?" he grinned and whirled away from the console, making his way toward the doors before Dean stopped him with a grim expression. "Doctor, maybe we shouldn't."
"Why not?"
"If we're on an alien planet, they... they may not have pie."
"Then who gets to be the very first one to introduce pie to their planet? The Winchesters! You might be made into gods!" the Doctor winked. Dean straightened and made an interested face, and then smiled. "Well, you know, what could really be the danger? I mean, I wouldn't mind being worshipped."
"That's the spirit! Come on then, allons-y!" the Doctor shouted, waving his arm in the air and flinging the doors open. He bounded out of the TARDIS and frowned as the Winchesters followed him out. "This... this isn't right." he muttered. Sam rolled his eyes and Dean grumbled. "What the hell is it this time, Space-Man?"
"Well... this isn't right. We're not in the 51st century, or any century for that matter. I dunno where we are!"
"Oh, awesome. Well, as long as they've got pie, you can take me to Jupiter and I'll be fine."
"Don't be stupid, Dean. They don't have pie on Jupiter. Jupiter is a gas planet. You can't have pie on a gas planet." the Doctor rolled his eyes, as if this was important, well-known information. Dean smirked at Sam and looked up into the sky, where he saw tons of huge, silver blimps flying around like big, lazy whales. "Are those... Zeppelins?" he demanded. Sam shielded his eyes from the beating sun and looked up as well. "Huh. Yeah, they are."
"Aren't Zeppelins like a World War Two thing?"
The Doctor's expression turned dark and the shadow of a Zeppelin darkened his face even further. "No..." he whispered. Dean and Sam's head instantly snapped their heads toward him, dreading what he was about to say. "What?" Dean demanded. "It can't be!"
"What can't be?"
"We've not jumped time tracks."
"Well that's good, isn't it?"
"No, it's not good at all! We've slipped through to a different dimension! But I closed the Rift... so how could we? Maybe Torchwood's opened it again. If they even have a Torchwood here. Do they? Maybe they've got a Jack. No, no side-tracking, Doctor! Come on, you've got to focus!"
"What the hell is going on, Doctor?"
"We're in a different dimension - oh, such an impossible dimension."
"Awesome! They must have great pie."
"Dean, this is serious! We can't be here!"
"Why the hell not?"
"Because... because someone from my past is here. Someone very, very dear to me, and I don't want to have to say goodbye to her again. I didn't finish the first time, and I don't need to. I'm sure she knew what I was going to say."
"Okay, buddy, slow down. Who is she, and what do you mean, you 'didn't finish the first time'?"
"Her name is Rose Tyler. She was my companion - she flew with me in the TARDIS for a long, long time. When she and I were saving the Universe together, she... she fell into this dimension and the Rift started closing. I only had a little amount of time to say goodbye, and... stupid Doctor, I stalled for too long. I didn't get to tell her." the Doctor whimpered. Sam looked at him with sympathy, and Dean actually felt really bad for the guy. "Tell her what, Doctor?" Sam urged. The Doctor sniffed, blinking the wet, hot tears out of his big, brown eyes. "I didn't get to tell her that I - " Before he could finish, a pedestrian bumped into him, not focusing on where he was going. The Doctor apologized and seemed to thoroughly examine the man's ears. When he was satisfied, he sprinted to the pedestrian. "Excuse me, do you happen to know where the Tyler estate is?" he wondered politely. The man pointed to the west of the city. "Yeah. They've got a property out there." he replied before turning away and continuing to walk down the street. The Doctor whirled toward the Winchesters and looked at him excitedly. "Are we gonna go see her?" Sam demanded. The Doctor shook his head profusely. "We can't. I don't want my hearts to break again."
"C'mon. What's the worst that could happen?"
"She could die!"
"That's always the worst thing that could happen, Doctor. Let's go find her!" Dean urged. Sam nodded enthusiastically, and when the Doctor hesitated, they grabbed his skinny arms and hauled him down the street, to the west of the city toward the Tyler estate.
