It's all AU.

John had been standing under a tree out by the woods, sharpening his knife, when he felt a very distinct pull. He dropped the blade onto the floor, and held his hand to his forehead, eyes squeezed shut. His mind skittered as he tried to place it, but it was too garbled and faint to make much sense. Like a radio tuned to the wrong frequency. Too many snatched voices, and not enough clarity. He slumped down the tree until he was sitting at the base of it. 

He thumped the ground with his free hand and he growled low, as a strong twinge of pain racing through his head made him wince.

What the ever-loving fuck was that?

He was aware dimly that footsteps were approaching, and his eyes shot open to see..

Jack, standing over him.

"What the.." he managed to croak out, before letting his head drop back into his hand.
