Jack doesn't seem to notice. He's busy running. By the time he hits the trees, he's stumbling as he runs, making growling noises that start as pain but then start to turn into something more animalistic.

Before long he's running in great bounds, on all fours, not sure why he's running anymore but still keeping up the impulse. He's leaving behind an easy enough trail to follow, for John to find, heedless of anyone potentially following him.

He stops running when one of the nargacuga find him and leap onto him, only to get hurled away and then leapt onto, in turn, and torn apart with teeth and claws. He pauses, bending over the bloody remains, sniffing in confusion. The wolf knows lots of scents, but it doesn't know these. What is it? Is it food?

It gives John some time to catch up.
