It alternates between the perspective of the Winchester brothers and the Sherlock duo with appearances of Doctor Who ( and briefly Dan and Phil)

The heading of the chapter makes it obvious which fandom your reading about.

Working out a good plot line to bring the three fandoms together (feasibly) and in character, was a real challenge but I think I've managed it. I wont give any spoilers but hope you like it, if you think you've figured it out at any point, leave a comment, it'd be great to hear your thoughts. I hope I can do them all justice, sorry if mess it up (if I do something wrong please tell me and I'll fix it straight away)

also my knowledge of London geography is pretty vague

Okay enough rambling, enjoy!

(Supernatural POV)

Dean decided he definitely liked boats better than flying, though as he sprawled across one of the two single beds, his thoughts kept returning to an image of the Titanic. They'd seen a couple of icebergs a while back, nothing close enough to be a risk, but Dean had found it somewhat unsettling that something as basic as a piece of floating ice (no matter how big it might be) could bring down something as large as a ship like this, never mind one as big as the Titanic, it just seemed…unnatural. There was no way in Hell he was going to tell Sam about that though, he'd never live it down, but he couldn't wait to be back on the road.

He thought longingly of his Impala, waiting back home God knows (then again maybe not even God knew) wherever Cas had put it for 'safe keeping'. Dean didn't want to think about where the angel had stashed his Baby, it didn't bear thinking about because angels just didn't place the same value on inanimate objects. So even with the multiple death threats to ensure she returned unharmed- which Castiel knew to take seriously-he still worried.

Dean sighed, it wasn't going to do any good dwelling on it. He folded his arms behind his head and leaning back on the surrogate pillow and closed his eyes, he heard the sound of the door sliding open, but didn't look until his brother spoke.

'Don't trouble yourself, I'll just eat the pie myself.' Dean's head turned towards him, sitting up as Sam, balancing a tray precariously in one hand while he closed the door behind him.

'No problem,' Dean grinned, then craning his neck to look asked, 'where's the pie?'

Sam rolled his eyes, 'here' he said tossing Dean a white box.

'You heard anything more from Cas?' Sam asked him as he sat down, putting the two coffees down on the bedside table, and tucking the tray under the bed out of the way.

Dean shook his head shovelling a mouthful of apple pie into his mouth 'oh my God, you have got to try this!' He exclaimed, Sam declined and Dean shrugged 'your loss.'

Sam wasn't going to be distracted though, 'so what do we know exactly?'

'Sam we've gone over this how many times already?' The eldest Winchester groaned.

'We need to make sure we know as much about what we might be up against before we get there.'

'Weird killings...angels...blah blah blah...yeah we know that already, one of Cas's...friends, or whatever, needs our help to stop someone ganking angels, what's new?'

'But we don't know what's killing them.'

'Exactly , so we go guns blazing, and shoot whatever it is with everything we have until something offs it, just like we usually do.'

'I just don't like this.'

'Sam it's Cas.'

'Yeah I know, it's not Cas I don't trust it's just that we don't even know this guy, and Cas's judgement isn't always great, remember Crowley...all I'm saying is Cas'll do anything for the 'greater good'. How do we even know this John Smith guy isn't the one ganking them, is he even an angel or what?'

'No idea' Dean said, 'we'll just have to be on our guard and nothing'll go wrong.'

'Yeah I've heard that one before.' Sam snorted, but sighed 'fine, but just so you know, if we get killed I'm blaming you and your boyfriend.'

'Fine, whatever...wait, boyfriend?' Dean looked up at Sam who laughed at his expression

'just kidding Dean. Got to admit you'd make an adorable couple though...Ouch!' Sam yelled as the heavy backpack hit him squarely in the face.

Dean sat back smugly with his coffee, just as an announcement rang out of the ship's speakers.

'We will soon be arriving at London Southampton. Please ensure you collect all items in preparation for your departure. We hope you have had a pleasant journey on board The Angeles.'

'Finally!'

'It's been a few days, you know, it would have been a lot faster if we'd just flown.'

Dean scowled at his younger brother 'Just get your stuff and let's go meet our damsel in distress/possible angel killer, and do our damned job.'

Yes I know, I made a Destiel joke and i'm not sorry :P I can't promise there wont be any more (or Johnlock ones for that matter) but I promise that's it. Nothing explicit, no smut and no cannon relationships, no harm in a couple of jokes though is there ;) that's part of belonging to those fandoms (even the TV crews understand that). Anyways hope you liked it. Comment on what you thought below

(whether you liked it or hated it, I appreciate honesty.)

CONSTRUCTIVE criticism though if you please) or even follow the story if you want to read more :)
