Thank you very much for the kind words and congratulations!☺️💕💕💕💕 It's okay <3
Sam and the other teachers immediately feel that something is wrong with Ciel. And experienced students like Leona, Malleus and Lilia too. But the students do not understand this immediately, I think they needed to concentrate and really try to feel something (Ciel doesn't have any magic after all, this black magic belongs to Sebastian. Ciel just has a "confirmation" that black magic is connected to him, but he doesn't have one, ofc. After Sebastian's appearance, Ciel's suspicious aura will become really stronger)
Once I actually answered the question of the interaction of these two:
I think spirits, Sam (and also ghosts) knew better than anyone that Ciel was connected to something bad. Maybe it's hard for them to believe it because it's still a child, or even if they somehow ask Ciel something, he can just say nothing or change the subject💔
In general, it will be really difficult for Sebastian and Ciel! I'd like to draw some epic scene about them and Sam XDD💕💕💕
I hope I explained everything clearly and interestingly💦💦 Feel free to ask anything else. Thanks for the question!😊💗💖💗💖
