The story continues for the Consulted crew in A Day of Duality!

Sam shifted in place as John stopped, blinking at the world around him. “Somethin’ wrong?” he asked blearily, pulled out of a daydream he’d fallen into during the walk.

Then Sam heard it too. A faint cry in the air, something easily overlooked. His ears pricked up, and he paid close attention to the back of his neck, alert for anyone other than John around the alley. “Sounds like someone’s hurt,” Sam said, glancing around. That didn’t sound like the call of an injured animal, and out in London that was less likely to happen.

“Yeah,” John agreed, stepping gingerly into the alley. For a voice to be that soft, one of two things had to be true. On the one hand, it could be an injured human in the far distance, in which case John would have to be incredibly careful with Sam.

No one would speak of it, but since Sam’s kidnapping all those weeks ago there was an enhanced sense of responsibility between John and Sherlock to protect their friends. There was a much greater risk to anything that ran the chance of Sam or Dean being seen. Other humans were always a wild card, especially strangers.

Then again, on the other hand, the voice could seem distant because the person it belonged to was a borrower, closer to Sam and Dean’s size.

John didn’t know which he dreaded more. Even so, something in him wouldn’t let him turn his back on someone who needed help.

Sam was attentive as John went, his ears tuned to the voice they’d heard on the wind. There was no sense that they were being watched, no feeling of eyes on him, so he frowned, wondering who could have called for help.

“Do you think–” Sam started, then cut himself off.

Down on the ground of the alley, he’d caught sight of motion against the ground. Just a flicker, but there.

Sam might have passed it off as a mouse hiding from John if he hadn’t spotted color.

Nudging John in the neck, Sam motioned at the ground. “Watch it, I think someone’s here.”
