"Yeaurgh!" Sam exclaimed as he was suddenly pulled out of yet another nightmare.
They'd stayed long enough to bury Jess before they set off to the coordinates their father had left them in his journal, and throughout that entire time, Dean's dog which wasn't looking quite as ugly as it had when he'd first laid eyes on it had never left his side. This had to be the fifth time he'd been pulled from a nightmare by the creature having licked him awake, and he didn't know whether to be thankful and disgusted.
The sixth time that he was pulled from the nightmare, they were at the coordinates where they soon learned that they were hunting Wendigo.
"So, your invisible dog is going to protect us?" the hunter - the normal sort that went after wild animals, not their sort - that the missing campers' sister had hired to track the "bear" that had gotten her brother said before laughing. "Is that before or after the Easter Bunny shows up?"
The man quit laughing later after Dean's dog rescued him from the Wendigo, asshole though he was.
"So, what was it you boys hunt again?" the man asked days later as they headed back after dealing with the Wendigo, warily giving Dean and his "invisible" canine companion a wide berth.
