A/N:I am a sucker for crossovers, so I thought I'd write one. This is set right before Dean gets to Lisa's house. For the Doctor, it is during that in-between time when the Ponds have stopped traveling with him regularly. Enjoy!

Disclaimer: I do not own any of the characters.

A Little More Time

"Goodbye, Ponds!" said the Doctor, almost managing to sound cheerful as he dropped his friends off in the house that he had given them. He knew that he would see them again, but he always hated saying farewell to them. He hated knowing that they were slowly edging him out of their lives.

He waved one last time at Amy, and then pulled the TARDIS door shut and sauntered back to the console. His fingers glided over the controls, and he frowned slightly. All of time and space before him, but he could not for the life of him think of one place he wanted to go next. He leaned in closer.

"How about a surprise then, Dear?" he asked the TARDIS. "Where would you like to go this time?"

The console hummed to life, and the Doctor smiled, holding on with a laugh as the floor bucked beneath him and they began to hurtle through time and space. The trip was surprisingly short, and they soon landed with a jarring thump. As usual, the Doctor did not bother to check the displays to see where they were; he simply dashed to the doors and threw them open, looking out with excitement. The only thing he had time to register was that he was on earth, around the same time as he had just left, and it was nighttime. Then he heard the squeal of tires and a loud curse, and looked up to see the blinding glare of headlights coming directly for him.

"What the hell are you trying to do, get yourself killed?" shouted an angry voice. The human that it belonged to had just climbed out of a black car, a '67 impala, unless he was quite mistaken. He had seen a lot of them during his exile on earth. They were good cars, though he was biased towards Bessie, his personal car. He still missed her occasionally. The driver appeared to be a man in his thirties, good looking by human standards, but something about him seemed different. "Hey! I asked what you were doing in the middle of the road."

"So you did. And I would give you an answer, but I don't really have one that would satisfy you," the Doctor replied.

"But are you alright?"

"Oh yes, quite fine. You must have very good reflexes, which is nice for me, because I don't really fancy getting hit by cars. It's really rather uncomfortable."

The man stared at him, and the Doctor stared right back. There really was something about him, something that the timelord could not quite put his finger on. But aside from that, there was a tremendous sadness in his eyes, unusual for one so young.

"Are you alright?" the Doctor asked gently.

The other man opened his mouth, looking ready to spout some offhand reassurance. But then his face changed and his breath hitched, and he answered honestly.

"No. No, I'm not. Would you mind moving your…police box, out of the road, so I can get to where I'm going?"

"I will, if you tell me what's wrong."

"Why do you care?"

"I'm the Doctor, it's my job to care. At least tell me your name."

"I'm Dean. Dean Winchester."

"What happened to you, Dean Winchester? What's given you eyes as old as mine?"

The man stared at him. It had been a long time since the Doctor had seen someone so broken, except for when he looked in the mirror. Evidently Dean decided that it was not worth getting into an argument over.

"I lost my brothers," he choked out. "They're gone. They're burning in hell, and I'm never going to see them again. That good enough for you? Can I go now?"

"What makes you think you're brothers are in hell, Dean?" asked the Doctor. He was rarely one to argue with religion, but he had never seen any evidence that there was a hell, or any other kind of life after death, and he did not want this man to torture himself over nothing. But Dean's next words surprised him.

"Well, it might have had something to do with the fact that I watched my little brother open the door to hell and jump in," he said with biting sarcasm, clearly not expecting the timelord to believe him.

The Doctor gazed searchingly at Dean. He saw no trace of madness in the man's eyes. But surely what he was saying was impossible. Then again, the TARDIS had brought him here for a reason, and maybe that reason was to have his world expanded just a little more.

"Well, I'm an alien," said the Doctor. He had meant to throw Dean off balance, to distract him from his obvious grief. He succeeded.

"Excuse me?"

"I'm a timelord. Over a thousand years old. I've even got two hearts, which I think is pretty cool."

"You're insane," Dean told him bluntly.

"Probably, but I'm not lying. Hang on, I can show you proof."

The Doctor fished around in his pockets for a moment, before pulling out his stethoscope. He handed the headpiece to a bewildered Dean, and pressed the metal disc against his chest. When he was sure that Dean had heard one of his hearts, he slid the device over to the other one. Dean's eyebrows rose.

"Okay," he said, pulling the stethoscope from his ears. "You've got two hearts. That just proves you're not human. It doesn't mean you're an alien."

"What else would I be?"

"I don't know, but I'm sure that there are some monsters out there with two hearts. Look man, normally I would be trying to figure out a way to take you out, but right now I just don't care. You're not trying to hurt anyone, and I'm not hunting anymore. So can we please just call it even and go our separate ways?"

The Doctor was not sure what that meant, but clearly this man was different. He must have seen some things that would surprise even the ancient timelord. The Doctor pushed open the door of the TARDIS and motioned for Dean to follow him inside. After a moment of hesitation, the man complied.

"Dean Winchester, meet the TARDIS. Time And Relative Dimensions In Space. My very own time machine from another galaxy."

Dean stared around silently, the grief on his face giving way slightly. He glanced back outside, checking to make sure that the police box really was as small as it appeared. The Doctor smiled, waiting anxiously for those wonderful words.

"This looks like the set of a made-for-TV sci-fi movie."

The Doctor's face fell into a dissatisfied frown.

"You're supposed to say 'it's bigger on the inside'," he told Dean grumpily.

"Well, duh. Anyone with eyes can see that. So I guess you really are an alien."

"You don't sound surprised."

"I guess I've seen too much to be surprised by anything."

"Now that I don't believe. Because I have seen so very very much. And I can tell you that there is always something out there to surprise you."

"Yeah? Well if there is, you and your time machine ain't it."

"Hmph. Well…you're not that impressive either."

"Yeah, thanks Doc. Well, unless you're planning on abducting me, would you mind moving your TARDIS out of the road? I have somewhere to be."

But the Doctor could not let him go, not when the agony was still so clear in Dean's ancient eyes. He had to do something to alleviate some of that pain.

"What really happened to your brothers, Dean?" he asked. The young man had said they were in hell, but that could have been metaphorical. He needed some specifics. "There might be something I can do to help them."

"I wish that they had just died," said Dean bitterly. "I would still miss Sam, but at least I would know that he and Adam were in heaven. I mean it's a little shady up there, but it is so much better than what they got."

"What happened to them Dean?"

The Doctor hated to keep pressing, because he could see how much pain the young man was in, but he had to know the truth. Because maybe then he could help.

"It doesn't matter. I can't help them. I have looked through every single possible option, but there is nothing. I can't do anything for them."

"But maybe I can. I have a really rather powerful machine. There's not a lot she can't do."

"Yeah? Can she pull two people out of the deepest, most well-guarded pit of hell?" Dean asked, clearly not expecting an affirmative answer.

"Hell?" he repeated. "You mean an actual, physical location?"

"Yeah, I didn't think so," said Dean, turning away.

"Dean, wait!" shouted the Doctor. If there really was a hell, and Dean's brothers really were in it, there was nothing he could do for them. But maybe there was something he could do for Dean. "Maybe I can't give you your brothers back, but I can give you time with them."

"What do you mean?"

"I told you this was a time machine. I can take you to any moment in your brothers' pasts. You'll be able to see them again, one last time. It's not a solution, but it may help to give you closure."

"Closure? They're still going to be in constant agony for eternity."

"Maybe, but there's no reason for you to be as well."

"I deserve it as much as they do."

"They can't deserve it much then."

"No, they don't. Look Doc, I appreciate that you're trying to help, but there's a reason I'm beating myself up over this, and that reason is that I'm responsible. And I know enough about time travel to understand that there's nothing you can do to fix that."

"So you don't want to see them again?"

"I didn't say that." Dean looked longingly at the console. "I…I do want to see Sam. Just one more time. Adam too, I guess. You'd really do that for me?"

ooooooooooooooooo

"I'll be damned. It really is a time machine."

"You sound surprised. Did you think I was lying to you?"

"No, it's just that the other times I've been time travelling, it was always an angel using his mojo, not a machine. I guess the idea of a payphone being able to travel through time and space just seemed a little hard to believe."

"It's not a payphone," said the Doctor rather indignantly. "It says 'free', very clearly on the side. And it's not even a real phone."

"Sorry," said Dean, raising his hands in surrender. "Either way, it works."

"Yes, it does. We're here. Are you ready?"

Dean sucked in a deep breath. He did not look ready at all, but he squared his shoulders and nodded. The Doctor pushed the TARDIS doors open, then stepped back to allow Dean to go through first.

They had materialized in what looked like the tiled hallway of a school gymnasium or auditorium. They could hear the notes of graduation processional music through a set of doors that had been propped open for ventilation. Dean walked slowly towards the music, the Doctor following. They found themselves in the back of a packed auditorium, watching hundreds of graduates file onto the stage. Dean searched the crowd of teenagers anxiously, before his eyes locked onto one of them and filled with an impossible combination of joy and sadness.

"There he is," Dean said, pointing out one of the boys to the Doctor. "That's Sammy."

"My, he's rather tall, isn't he?" said the Doctor, following Dean's gaze. "He must always have an incredible view."

Dean chuckled.

"Yeah, you know he was a shrimp for the longest time. I towered over him. But as soon as he turned seventeen, he just shot up, wouldn't stop growing. He's in that gawky stage now where he's not used to all that height. I remember he was always tripping over things…"

The Doctor glanced back at Dean, noting the nostalgia and pain in his voice. He wondered once again whether or not he was doing the right thing here. It would not help the man to be forever stuck in the past, unable to move on from his brother's death.

"Where are you, Dean?" he asked eventually as the principal of the school got up to make his introductory speech.

"Excuse me?"

"The version of you that goes along with this time. It's your little brother's high school graduation. That seems like kind of a big deal. Why aren't you here?"

Dean looked away and snorted bitterly.

"I was on a hunt," he admitted. "A chupacabra, I think. I let my dad talk me into it. He even wanted to make Sam skip this ceremony, but we both drew the line at that. So we left him here alone. We were always putting the job ahead of Sam."

"You shouldn't be too hard on yourself Dean," the Doctor told him gently. "I can't imagine Sam would have wanted that. Besides, you're here now."

"Yeah," muttered Dean, staring back at the stage. "Thank you for this, Doc. It…it means more than I can tell you to be here for him."

"I think I understand," the Doctor replied softly.

They were both silent for a moment, listening to the rest of the speech. When the principal had finished, she introduced the valedictorian, who would be giving another speech.

Sam Winchester.

The Doctor heard Dean pull in a sharp gasp of shock, and glanced over at the hunter.

"You didn't know?" he asked.

Dean shook his head, staring with pride at his little brother as the young man walked across the stage to the podium.

"He never told me," whispered Dean. "No wonder he wanted me to come."

Sam searched the crowd nervously before he began. He looked towards their corner of the auditorium and seemed to do a double take when he caught sight of Dean. The older Winchester gave his brother a proud, albeit slightly tearful smile, which Sam returned before launching into a really rather excellent speech. The Doctor listened in silence, knowing that he was hearing an impressive young man.

"So yes," finished Sam. "This is the end of something remarkable. We will never again be the community that we are now. We will go our separate ways, and some of us will never see each other again. But this is more than an end. It is an opportunity for more, an opportunity to join new communities and forge new relationships, to take chances we never dreamed of and follow paths we have hardly dared to hope for. This is the time in our lives when we stop thinking about changing the world, and start doing it. We all only have one lifetime to make a difference. So let's make it a good one."

Dean and the Doctor burst into furious applause as soon as Sam had finished speaking. The young man's eyes did not leave Dean's until he had to step down from the podium and head back to his seat.

"He didn't get it," said Dean sadly as they watched the first of the students collect their diplomas.

"What are you talking about?" asked the Doctor. "I thought he did an excellent job on the speech, and keep in mind I've met Shakespeare, so my standards are pretty high."

"What? Oh no, that's not what I meant," said Dean quickly. "Sammy rocked that speech. I meant that he didn't get to have those new relationships, or that path he dreamed of. All he wanted out of life was a job as a lawyer and a nice family. And he would have had it too, but the universe screwed him over."

"I'm sorry," the Doctor told him, knowing that there was nothing else he could say that would make the hunter feel better.

"Yeah, me too. But you know what? He did change the world for the better. He saved hundreds, maybe even thousands of people as a hunter, and he saved all of them when he beat the Devil."

"He sounds like a great man," said the Doctor softly. He meant it too. He had met so many people in his lifetime, and Sam Winchester sounded like one that would have stood out among them.

"Yeah, he was."

They waited in silence for a moment, but then the rest of the Doctor's words seemed to sink in for Dean.

"You've met Shakespeare?" he asked incredulously.

The Doctor grinned.

"Oh yes. Brilliant fellow. He was a bit full of himself, but then, he was Shakespeare, so he could afford to be."

Dean chuckled in disbelief.

"Doc, you are nine kinds of crazy," he said, but the Doctor could hear the warmth in his voice. "Sammy would have liked you."

"I'm sure I would like him too," said the Doctor.

The conversation lapsed again and the two of them watched as more and more students received their diplomas, until finally Sam's name was called. As the young man rose from his seat and began to cross the stage, Dean and the Doctor shot to their feet, applauding wildly. Dean gave a whistle so loud that it hurt the Doctor's ear. Sam looked back at them, shooting Dean an appreciative, if slightly embarrassed smile. He also spared a confused glance for the Doctor, probably wondering why the strange man was giving him a standing ovation.

When the ceremony was finally over, Dean immediately began to cut through the crowd towards the stage, the Doctor following a few paces behind. Sam's height turned out to be a good thing, because it made him easy to spot in the throng of people. The Doctor slowed down as they approached the young man, giving the two Winchesters a bit of privacy.

As soon as he was close enough, Dean pulled his little brother into a tight hug.

"Congratulations Sammy," he said when he let go.

"I can't believe you're here," laughed Sam.

"Of course I'm here. You didn't think I'd miss watching all of your geeky studying pay off, did you?" replied Dean through the suffocating lump in his throat.

Sam just smiled wider. He did not bother asking about their father, they both knew that he was not there.

"I'm serious Sam," said Dean, catching one of his brother's shoulders and looking him in the eye. "I am so proud of you. I always have been."

Now it looked as though Sam was fighting back tears of his own.

"Thanks Dean," he whispered. "Are you alright man? You seem…different. Older. Did something happen that I should know about?"

"I'm fine Sammy. Everything's fine." Except for the fact that Dean's entire world had collapsed around him, vanishing into the ground in that cemetery in Lawrence. Except for the fact that he was facing an eternity without Sam. "Listen, I just want you to know…even when it feels like I turned my back on you, or given up on you, or anything like that, know that it's not true. You will always be the most important thing to me, ever. Promise me you won't forget that."

Sam stared at him. When he realized that his brother was serious, he replied,

"Yeah, of course Dean. You know that goes both ways, right?"

Dean pulled Sam into another hug, knowing that it was time to go. He closed his eyes, a few silent tears escaping his closed lids and trailing down his face into his little brother's long hair. He felt a rush of jealousy for his twenty-two year old self, who was currently two states over, getting his ass kicked by a chupacabra. That Dean still had time with Sam.

"Yeah, I know," he said gruffly. There was one more thing he had to say, the thing that they never said, but really should have. "I-I love you, little brother."

He pulled away, ruffling Sam's hair and giving him a watery smile. The teenager looked worried, clearly aware that something was very wrong, but Dean did not give him the chance to ask about it. He just turned and disappeared into the crowd, heading back to the TARDIS and the mysterious Doctor.

Sam called out to Dean, trying to follow him, but the Doctor stepped into his path.

"Let him go, Sam," he said gently. "You'll see him again soon."

"Who are you?" asked the teenager suspiciously.

"Oh, I'm nobody important, just a friend of Dean's. I was just giving him a lift here."

"Oh. Well then thank you, I guess." He extended a hand. "I'm Sam. What's your name?"

"Call me the Doctor," the timelord replied, taking Sam's hand and shaking it energetically. "Listen, I just wanted to give you some advice, for what it's worth. I've been around a bit, you see, so I suppose I'm qualified."

"Okay…"

The Doctor leaned closer.

"Learn as if you will live forever. Live as if you will die tomorrow."

"Isn't that a quote from Gandhi?"

"Yep," said the Doctor with a smile. "Great man, Gandhi. He always beat me at staring contests. Anyway, why make up new advice when you don't have to? But I will tell you this; have fun. Do that for me, eh? Just live a good life, Sam Winchester. And take care of that brother of yours."

With that, the Doctor spun around and departed. He did not even bother asking Dean if he was okay when he came back into the TARDIS. The tears snaking down the other man's face were indication enough. So he turned away, giving Dean the privacy to pull himself together.

"What about your other brother?" the Doctor asked when he was sure that the hunter was composed. "When would you like to go in his life?"

Dean sighed.

"Yeah, Adam. The thing is, Doc, I never really knew Adam. I didn't even know he existed until he was already dead. So it's not like I can go be there for him, because he won't know who I am. I think the best thing I can do for him is let him have those nineteen normal years with his mom."

"Alright; as long as you're sure."

"Yeah. But there is one last stop I'd like to make, if it's alright Doctor."

"What's that?"

"There's something I want to get."

ooooooooooooooooo

"So you died here?"

"Yep. Shot by a couple of hunters. I guess we should have been expecting it. We did start the apocalypse, after all."

Dean looked sharply at the Doctor, seeming to dare him to criticize. As if the Doctor could possibly look down on Dean after everything that he himself had done.

"Anyway," continued Dean after a pause, "we went to heaven and…I don't know. I realize now that Zachariah was probably pulling the strings, trying to screw with our heads and push us apart so that we would say yes, but at the time, all I could think was that Sam had never wanted to be a part of the family, never cared as much about me as I did him. I just felt so betrayed, and I threw away the amulet that he gave me when we were kids. God, he must have felt like I was throwing him away."

Dean trailed off, his eyes misty as he got lost in the memory. Then he shook himself and bent down to reach into the trashcan by the door. Confusion overtook his face as he rummaged through it. Eventually he just overturned it, dumping the contents onto the floor.

"It's not here," Dean said finally, glancing up at the Doctor. The timelord coughed uncomfortably.

"That may be my fault," he admitted. "I have been known to land on the wrong day. Or year. But I'm positive that we're in the right decade."

"No, it's the right day," said Dean. "Look, there's still blood on the sheets from when we got shot. And all the other trash is here. I remember eating at the diner that this receipt is from."

In that case, the Doctor suspected that he knew what had happened, but he wanted to let Dean arrive at the conclusion on his own. He watched as realization dawned on the hunter's face.

"Oh, Sammy," Dean whispered, the pain in his face growing more pronounced. "He fished it out of the trash, didn't he? Even after everything that I said to him, after I threw our relationship back in his face, he still kept it."

Dean stood. The Doctor could tell that he was fighting against tears again, but it was a fight that he was loosing.

"I'm sorry Dean," he said again. It felt as useless as the last time he had said it.

"No. Don't be. It means he still has it. Wherever he is, whatever he's going through, he still has the amulet with him. I'd rather he had it than I did."

ooooooooooooooooo

"You're sure there's nowhere else I can take you?" asked the Doctor after they had landed in the same spot they had met. "There's so much to see out there. I could take you anywhere."

Maybe enough travelling, seeing enough amazing sights, would ease some of the agony from the young man's eyes. Dean gazed thoughtfully around the TARDIS, before grimacing ruefully, and the Doctor knew what his answer was going to be.

"Thanks for the offer, Doc," he said, "really. But…I've gotta stop running sometime, right? Sam wanted me to have a normal life, so that's what I'm gonna do. I think there's a great woman and kid waiting for me out there. And you know what? I'm tired of travelling. It's time to settle down."

The Doctor smiled at him. He admired the hunter's strength. Sometimes he wished that he had the courage to stop running from his loss.

He whirled around and swiped a sticky note from the console, and handed it to Dean.

"In case you change your mind," he said.

"Thanks," said Dean with a tiny smile as he glanced down at the Doctor's phone number. "And if you ever need anything, you come and get me, you understand?"

"Yes, sir," said the Doctor.

He watched sadly as Dean squared his shoulders and walked out of the door. He knew that the young man was strong, that he would be all right, but he sure had a long, painful road ahead of him.

A/N: Thank you for reading! I will be adding a new chapter/epilogue sometime soon. Please review!
