day 4: write a short fanfiction from one fandom set in the universe of another.

Something had gone terribly wrong, as usual, with the Doctor's landing/aiming skills. He'd promised to take Rose to meet Sherlock Holmes but the wormhole they'd used got all wibbly wobbly on them and spat the TARDIS out in a completely different alternate reality. The ride had been unusually bumpy, not that the Doctor would ever admit it, and Rose just watched him wordlessly from the copilot's chair in the control room of the TARDIS for a while, amused by the whole thing.

When they finally landed it was with a crash and not the normal whirring noise the TARDIS usually made upon landing. Obviously this isn't normal and the Doctor was trying to pretend like it was, "Alright so, alternate universe where Sherlock Holmes is real. Why did you want to come here again?" Rose grinned and hopped off her chair, walking over and wrapping her arms around his waist, "Because I'm a horrid fangirl and I need these two to get their shit together." He snorted and shook his head, pretending to be embarrassed by her but he was still grinning like an idiot because Rose had her arms around him and she was real and they were together, at least for right now. "Well come on then. Allons-y!"

The two of them half run and half spill out of the TARDIS, only to come out in the middle of a shitty motel room that appears to be somewhere in America. "Doctor... something tells me you overshot the landing a bit." Rose is walking around the room and trying to figure out where and when they are when a rather handsome man opens the door to the motel room with two other guys, an extraordinarily tall young man with impractically long hair and an almost pretty slightly older looking man in a trench coat, following behind him. The first man freezes and looks at them like they're holding bombs, "Who the hell are you, how the hell did you get in here, and what the fuck is that?" He's gesturing towards the TARDIS and his hand is resting on the back of his jeans where Rose can only assume there's a gun. Of course the Doctor is playing the part of completely unfazed quite well, "Hello there! I'm the Doctor, this is Rose we're..." He flashed the psychic paper in front of all three men's faces who were now standing inside the motel room with them. The first two seem to buy it but the third man, the one with the blue eyes, is tilting his head to the side and looking at the Doctor like he has four heads. "That paper is blank." Oh this one's clever.

"What do you mean Cas?"

"No he's right Dean, look at it again. It's blank."

Dean practically rips the psychic paper out of the strange dude in a blue suit and Chuck Taylor's hands, frowning as he turns it over in his hands. "What the fuck kind of hoodoo is this Cas?"

"I believe you would call it 'alien' technology, Dean."

Rose and the Doctor are standing together in front of the three of them, watching with both a bemused and impressed expression on their faces. Apparently all three of them are quite clever and all Rose can think is if Jack was here, this whole situation would be even better. He's got a thing for tall, dark and handsome men and now there were three of them standing here.

The one who is apparently called Dean, the first one who'd walked in, frowned and stepped closer to the Doctor before poking his shoulder, "I thought aliens were supposed to be green."

"Well it depends on the species of alien and who knows, I could be green the next time I regenerate but probably not. If I've never been ginger somehow I doubt that I'd turn green."

Rose was trying not to laugh as the one in the trench coat that was apparently called Cas stepped uncomfortably close to her, eyeing her up and down before mumbling, "She appears to be human... and to have a pure soul." The Doctor frowned at the two of them and crossed his arms like a petulant child who's favorite toy was being played with by another kid, "Well I could have told you that."

The really tall one, the only one who hadn't been introduced by name, was over looking at the TARDIS and running his hands over her in a way that one would caress a lover. "If you're an alien, why do you have a 1950's British police box in our motel room?" Dean snorted at his little brother and crossed his arms, never taking his eyes off of the apparent alien, "He wanted to brighten up the decor. What the fuck do you think Sam, it's probably how they got in here."

Cas was still standing uncomfortably close to Rose, frowning as he sniffed her, "She does not smell human however... she also smells alien." Both Dean and the Doctor took immediate notice to their proximity and both men frowned deeply. "Oy, would you stop smelling her?" Dean almost growled when Cas didn't move back and Rose leaned in closer to him before leaning over and yanking his angel back away from the weird human-but-maybe-alien chick, "Personal space Cas." The angel frowned at him, tilting his head to the side again, "All humans require personal space?" Dean sighed in annoyance, "Yes Cas. All of us prefer it." Rose grinned, "I didn't mind."

Sam nudged the door of the TARDIS open with his foot and stepped inside without the two jealous couples in the motel room noticing. He whistled as he walked into the weird box further, taking note of how much bigger it was on the inside and maybe there was some hoodoo involved here or maybe Cas was right and this weird dude was just an alien. A British alien, mind you, traveling with a girl... maybe lots of planets have Brits? "Is this your ship?"

"No it's my wardrobe. Yes it's my ship what are you -" the Doctor turned around as he saw Sam start to go towards the one giant red button that you are never supposed to touch on the control panel, "Oy, moose boy, don't touch that!" Sam froze in place and spun around to face them with his hands in the air, "Sorry sorry. This is really cool though. Alternate dimension or magic or what?" The Doctor followed him inside the TARDIS and started blathering on, explaining what the TARDIS was and how it works and how she's definitely not magic or this hoodoo that they kept speaking of.

Meanwhile in the motel room Rose was watching Dean and Cas have an argument about personal space and good cop, bad cop. "So how long have you two been a couple?" Dean's head snapped around as he frowned at the blonde sitting on his bed, "We are not a couple." Cas nodded and didn't take his eyes off of Dean, "We just have intercourse from time to time."

"For fuck's sake Cas, how many times have I told you, don't call it intercourse. And thank you for making me sound like a cheap fuck, really appreciate that."

"If we are not a couple but I am not allowed to call it intercourse, what would you suggest I call it Dean?"

The hunter narrowed his eyes and walked inside the TARDIS to avoid having this conversation with the angel, not even batting an eye at how big the phone box was on the inside. After hell and purgatory, it was kind of hard to shock him.

"How can you tell what my soul looks like?"

"I am an angel of the lord."

"No way."

"Yes... way..."

"This is so cool."

"I do not follow..."

"Come on, the Doctor isn't going to believe this."
