Lilith was unsure of the glimmering brightness marked in his face, if his joyful manner would be of any good to her plan or to keep his identity low.
She knew that standing out amongst the other servant will draw attention which might hinder her discovery. However, this could be a good thing too, to help him from his suffocating bubble of loneliness and mingle with others.
But it looks like the two had not any concern but to welcome the boy, Lilith was relieved that Ada and Grahams seems to have not a care for her sudden recruitment nor was their face looked puzzled for where this young man had Lilith found.
Stewt, on the other hand, seems to want to chatter straight away with this young man but could only hold back at least in front of the Madam of the house.
With his clasped hands, his thumb dancing around on top of another, he politely greeted the new servant.
