He stood still, staring at the carrion dog in front of him, silent for a long, long time.
The dog was also well-behaved, not barking or running around. From its burst eyeball and the hollowed-out eye socket, it was clear that this creature was the one whose brain Sherlock had mashed in the dream.
However... it was now truly standing in front of him.
And it had emerged from the void crack he had torn open himself.
"Could this creature... have become my covenant demon?"
Sherlock of course knew how unrealistic this thought was, for from all the books, people's understanding of the covenant person, and even the knowledge about covenant demons that the old priest had imparted to him:
[The covenant person has, and only has, one covenant demon, which cannot be changed or replaced, to accompany them for life. Even if the covenant demon dies, one cannot form a bond with another demon.]
This was an unalterable rule.
But what's the deal with this dog?
