When Doc and Wynonna show up, the Stone Witch, outnumbered and ticked off, promptly disappears. She then reappears driving her pink Caddy far and away. Also? Doc was able to get one shot off at the Witch which grazed her arm. As the bullet hit her, Doc noticed that he too started to bleed from the same arm, as if he had also been shot. As if he and the Witch were some how linked. How curious.
