The Mad Doctor was a loner-used to people staying away from him in general due to his disposition and image, he was quite surprised when he saw someone say that they wanted to join him in something.
Of course, there were always requests to learn medicine under him, from those who prepared themselves to ignore his 'madness' if he was willing to teach them.
He was usually inclined to say 'f*ck off' to them, so the only ones he taught grudgingly right now were those doctors in the room outside, who had been assigned by the sect to ensure that his post wouldn't remain empty if he perished.
Hence, hearing someone say something like this, he couldn't help but pause.
As the fluctuating elementary particles in the room died down and started to return to normal, Daneel heaved a sigh of relief, feeling glad that his plan had worked.
