After skinny man's departure, Asil tried to calm the mess his mind is in now without saying anything. Sirius also said nothing during this time. It was almost impossible to say that his mental state, too, was as usual.
Skinny man's words and behavior had clearly put a great deal of psychological pressure on them. His behavior and manner of speaking completely obscured his true thoughts. This naturally caused the person in front of him to have the wrong thoughts about him and reduce his alertness at his side. According to Asil, someone like that was scarier than the most fearsome profound monsters. In the end, even though the profound monsters were powerful, it was obvious what they were going to do, but the skinny man was unpredictable. The most dangerous creature you could encounter in this world was a creature that could not be read and predicted!!
