Zoravec heard the voices of Hecate and someone else, which came from the lounge and appeared to be some kind of quarrel. It made him curious regarding who came into the house because he clearly heard the bang of the door. It was obvious whoever the person was had already barged into the house forcefully.
He immediately came downstairs to see who it was while Devi casted the invisible spell once again. She did not want to be seen like that just to get caught, when she could already sense a vampiric aura in the house now. The demoness knew the person could potentially smell her aura too which made her cautious and worried at the same time.
Zoravec on the other hand, was sure that neither William nor anybody else could potentially smell anything from him. His powers and aura were masked for some reason, which also indicated the unknown and unlocked potential of his powers. However, the class A and B vampires could smell and figure out such aura from other species.
