France, Middle of WWII, 1944 2PM

"Okay here's the plan. We split up. Who would like to go with who?" Eleven asked.

"That's your plan?" Dean rolled his eyes.

"It's less of a plan and more of a thing. Don't disrespect the thing." Eleven muttered.

"Fine, well I'm not letting Crowley out of my sight."

"Aw, not even after our adventures together?" Crowley chuckled at the memories.

"Actually it's because of that. You let me wander around as a demon!"

"Hey, I fixed that! Eventually."

"Uh-huh." Dean enunciated sardonically. He looked at Sam, who nodded and took a step towards Sherlock and Watson, neither of whom were willing to split up. Then the two parties disappeared off towards their respective TARDIS's.

Eleven wandered around the console, flicking levers while Dean, Castiel and Crowley leaned against the railing. He rotated the screen to face them and with the press of a button the other TARDIS interior appeared. Ten, Rose, Sherlock, John and Sam all gazed back at them and Ten frowned as he saw the new TARDIS.

"I don't like it."

"You never do." Eleven sighed, "Although, I do miss my grunge phase."

"Grunge? This is brilliant! Why is yours completely silver? You couldn't give it a homely edge; you had to make it look like the inside of a Cyberman's stomach?"

"Oh, you… shut up. So here's the plan. One of us goes back to the day where we felt the leak, and the other group goes stays in the past when it actually happened and we see what occurs." The Doctor tapped on a keyboard and the TARDIS started wheezing. Ten started flicking dials and said,

"I'll go to the location and just pray that it's not a warzone, you go to the leak," and then the screen went blank.

"That sound is oddly comforting." Castiel stared straight ahead as he spoke, his face not betraying any emotion.

"The sound the TARDIS makes, the wheezing, the groaning. That sound brings hope wherever it goes. To anyone who hears it; however lost." The Doctor said quietly, remembering the words of the interface when he was the War Doctor. The interface that looked like Rose; the Bad Wolf. He was never going to escape that woman. One day she would be the death of him. Well, she already had once or twice.

"That sounds like a mantra." Cas remarked.

"Yes, well, that mantra saved billions of lives. Including mine. A few of mine actually."

"You know, most of the stuff that comes out of your mouth is complete crap." Dean uncrossed his arms and smirked, letting them swing by his sides.

The grinding stopped and the door to the TARDIS swung open. In front of them was the same alleyway that the Doctor and Clara had stepped out in the day the adventure had started – the day the prophecy started coming true. Already the smell of sulphur was heavy in their nostrils and the readings on the TARDIS were erratic, showing a lot of rift activity and some indecipherable trace elements in the atmosphere.

"Yeah, this is definitely the place." Ten's voice echoed throughout the room and the Doctor looked over at the monitor but it was off, "So now all we have to do is see if there is a rift here and find out what's visible from my other end. Oh, no I'm never saying that again, forget I said that." A lot of laughter could be heard, sounding like Watson, Rose and Sam. Crowley looked around but there was no-one there.

"Well. That'll be the rift then." The Doctor said.

"No shit, Sherlock." Dean said.

"Oi! Rude. Okay so there's definitely a leak here. Now we just need to work out what exactly happened on that day, and why it leaked through to this day."

"Do you deliberately try to make your speeches confusing, or do you just normally speak like a four year old who ate a dictionary?"
