Dean waited in the living room, wondering where the Doctor was. Then again, he was usually late. Sam paced the hallway, thinking that Dean should not have invited the time lord. Cas waited in the middle of the room, finding himself useless, but Dean had asked him to stay at least for the next two days for the holiday.

"Cas," Dean whispered, catching the angel's attention. "You don't have to stand there."

"I know," Cas answered calmly. Dean sighed and turned on the TV to find A Charlie Brown Christmas playing.

"Have you ever seen this?" Dean asked as Cas shook his head. Dean gestured for him to sit down on the chair beside him. Cas cautiously sat down, unsure what this was about. Dean smiled, thinking that this guy was something else.

About five minutes in, Cas started to get really into the show. Every once in a while, Cas would ask questions. Why was the dog dancing? Is Lucy really qualified to be a psychiatrist? Why was the dog acting like a penguin? Dean would just shrug, unsure how to answer the question nicely. Cas usually didn't care about getting the answer, but was rather interested in the special. Sam came in every once in a while as well, wondering what was going on and which part they were on. Dean even saw him smile once before he went back into the hallway.

"That young boy is too smart for his age," Cas observed of Linus.

"How so?" Dean implored, not entirely interested.

"He talks like a wise old man, but he is a child," Cas replied as the credits started to role. Dean sat up, looking to see what was on next.

"You want to watch How the Grinch Stole Christmas?" Dean asked as Cas gave him a strange look.

"Dean, no one can steal Christmas," Cas insisted, making Dean laugh.

"We are totally watching this," Dean smiled, leaning back into the couch. Cas stared at him for a moment before turning back to the TV.

About halfway through the show, there was a knock at the door. Dean went to go get it, but Sam beat him to it. Dean reclined back as he watched the Grinch steal all the presents and Christmas decorations.

"Can I help you?" Sam asked after opening the door to the four strangers.

"Sam?" the man in the pinstripe suit asked. Sam tilted his head at the man before looking at the others.

"Do I know you?" Sam whispered, confused. The man frowned, almost like he was disappointed.

"Sam, it's me. The Doctor!" the man urged, making Sam laugh.

"Right, because you look just like him," Sam informed before closing the door. The man claiming to be the Doctor held the door open, staring at Sam.

"Sam, it really is me. Who else would know that Dean's been in Hell," the Doctor informed as Sam looked shocked. "Or that you called me after Dean went to Hell, talking about how you were going to get Dean back somehow."

"Doctor?" Sam asked, really confused. The woman rolled her eyes.

"Yes, it's the Doctor? Can we come inside now? I'm freezing my tail off!" she exclaimed before Sam let them in. She muttered a thank you as she came into the living room. Dean glanced up, surprised to see her there, and smiled.

"And who might you be?" Dean asked before the Doctor walked in.

"Stop it," he warned, looking around the place, hardly registering that Dean was there. Dean immediately stood up, staring at him.

"Doctor?" Dean asked as the time lord turned and gave a small smile. "You've changed since I last saw you."

"Yeah, it happens," the Doctor whispered, rubbing the back of his neck. Cas stood up behind Dean, shocked to see the man there.

"You," Cas whispered as the Doctor glanced between the angel and Dean.

"Who's this?" the Doctor whispered as Rose looked up at him.

"This is Cas. He's an angel," Dean answered, thinking that he never would have thought he would ever have to say that.

"Cas? As in Castiel?" the Doctor asked as Dean nodded slowly. "Well, this is a bit awkward."

"What are you doing here?" Castiel demanded as the Doctor sighed.

"Dean invited me," the Doctor answered before Dean looked at him.

"Dean," Cas whispered, upset. "Why would you invite him here?"

"You know him?" Dean asked, confused on what was going on.

"That man is a genocidal maniac, Dean. He has destroyed his entire planet," Cas informed as Dean nodded.

"Yeah, he told me that," Dean answered, still unsure what was going on.

"He's just angry because he planned to let the Daleks take over," the Doctor countered as Dean ignored him, not sure what that even meant.

"We never intended for that!" Cas shouted.

"You didn't stop them! Do you know how many people cried out for your help, Castiel? For the angels' help? You ignored them and decided that they were better off dead!" the Doctor argued.

"As did you," Cas reminded as the Doctor laughed angrily.

"Ah, but I killed off the Daleks, too. Or at least most of them. If I didn't do something, then the entire universe would have burned," the Doctor growled. Dean just sat down again as Sam took the other two visitors to meet Bobby. They had been standing behind the time lord and his companion when the argument broke out.

"We would not have allowed that," Cas informed, making the Doctor laugh.

"Well, I guess we'll never know," the Doctor sneered before Dean told them to stop.

"Can't you two get along for a little bit? It freaking Christmas," Dean reminded as Cas opened and closed his mouth, wanting to tell Dean to stay out of it, but decided that it would end badly for everyone. The Doctor looked away as Rose nodded, silently thanking Dean.

"Why did you want me to come so badly, anyway?" the Doctor asked, looking around. "I thought you were in trouble."

"I never said that," Dean answered, confused. "I wanted to invite you over for Christmas."

"Why? We didn't exactly leave as friends," the Doctor reminded as Dean bit his lip.

"That's why I wanted to invite you over. Spending time in Hell, it makes you remember things. Regret things. Yelling at you and fighting was one of things I most regretted," Dean answered as the Doctor stared at him, unsure how to respond.

"So no monster," the Doctor sighed, his mind running.

"What?" Dean asked.

"I promised Sherlock that he would get to see a monster," the Doctor whispered as Dean looked at him.

"Who?"

"I brought two others along with me. I think Sam took them somewhere," the Doctor added before Dean got up to go to Bobby's office. Reluctantly, the other three followed, hoping that nothing was wrong.

When Dean got there, he found that Sam was introducing Bobby to the Doctor's new companions. Bobby looked up, slightly irritated at Dean, before talking to the shorter of the two visitors. The other began to look around and seemed to be judging everything.

"Dean," Sam whispered, walking over to his brother. "Why did you invite so many people?"

"I didn't. I only invited the Doctor. It seems that the Doctor thought that we were in trouble or something and sent for back up," Dean explained calmly, looking over at the dark haired visitor. "Did these guys tell you who they were?"

"Yeah, the shorter guy, talking to Bobby, is Dr. John Watson, and the man examining everything is Sherlock Holmes," Sam answered as Dean nodded. "They seem normal enough and Bobby and John seem to be getting along."

"Well that's something," Dean whispered. "Apparently, the Doctor and Cas know each other, though."

"That's interesting," Sam replied, surprised by this. "How?"

"Long story. Let's just say that they are not on good terms right now," Dean answered as Sam nodded.

"So who's the fourth person? The woman?" Sam asked, looking over at Rose.

"No idea, but she's hot," Dean smiled as Sam rolled his eyes.

"I'm pretty sure you're not supposed to be hitting on the Doctor's companion," Sam informed, thinking that approaching her was a horrible idea. There was a small crash as Sherlock pushed something off the shelf. John exhaled as Bobby looked over to make sure that it didn't break.

"She's the Doctor's companion, not girlfriend," Dean countered as Sam pursed his lips.

"Just make sure first," Sam sighed before the Doctor came in. Bobby looked over at Dean before introducing himself.

"I assume that you are the Doctor," Bobby whispered, trying his best to be pleasant.

"Yes, I am," the time lord smiled as Rose came up beside him.

"And I'm Rose Tyler," she informed, shaking Bobby's hand next. Dean smiled over at Sam, who rolled his eyes again. "You have a lovely house."

"Well, I try my best," Bobby answered, looking at the two. "Can I get you anything? Beer? Eggnog? It seems I'm ill prepared for company. Dean just invited you over on a whim."

"Are we intruding?" Rose asked, looking over at Dean. Bobby shook his head.

"Of course not. I wouldn't have let you in if you weren't welcome," Bobby teased, making the other two nervously laugh. "So no on the drinks?"

"We're fine," the Doctor smiled as John asked for a beer. Sam went into the kitchen as Bobby sighed. "So, how long has Dean been out of Hell?"

"Oh, you knew about that? Well, it's only been a couple of months. Sam's still getting used to it. Can't say I'm used to it either," Bobby admitted, leaning against the desk. The Doctor nodded, understanding what he meant. "How do you know the boys, anyway?"

"Stumbled upon them, actually. Nearly killed me when they noticed that I wasn't human," the Doctor smiled as Bobby raised an eyebrow. "I'm a time lord."

"What's that supposed to mean?" Bobby asked, knowing that Dean wouldn't bring a demon to the house, but still.

"I'm an alien from the planet Gallifrey," the Doctor replied before Cas appeared next to Bobby, knocking the older man off his equilibrium.

"What he says is true," Cas whispered, glaring at the time lord. Bobby shrugged and sighed.

"Whatever works, I guess," he whispered, looking at the fireplace, not sure if he believed that the man in front of him was an alien. The Doctor smiled as Rose folded her arms. "So, are you going to stay for a while or what?"

"Well," the Doctor began.

"We'd love to," Rose answered, catching the Doctor off guard. Bobby nodded and smiled.

"I have a few spare bedrooms if you need a place to stay," Bobby replied before Sam came back in with a few bottles. "How about you, John? You staying?"

"Seeing that I have no other plans, I would like to," John replied, trying to get Sherlock to stop touching everything. Bobby smiled before wandering upstairs to make sure that the spare rooms were clean.
