It wasn’t surprising that Sebastian locked the hound outside, it was becoming more frequent however. The hound had started to get annoyed with the demon and merely turned his favoritism to Finny until the butler cooled down and wouldn’t react so harshly to Pluto. This time it wasn’t his fault! This time it was the other servants trying to catch yet another mouse that found it’s way into the manor. Though they mostly ended up in a pile, trying to process what just happened, while Pluto practically tore through the wall.
Despite how annoying Ciel and Sebastian found the hound to be, he was still a good guard dog. He would be friendly to people when needed but if it was a threat or intruder then he wouldn’t stand for it. There was never a time where he had been told to attack anyone, maybe one or two by Sebastian. But that was it. When Mey-Rin opened the door to let him in, he burst inside, knocking her to the floor. He simply crouched down, somewhat curled up on himself, and licked the wound on his arm as he looked over at the maid now being helped up by the others.
