Hans’s uncharacteristic rudeness suggests that the “magic” of the Berghof is already working on him: far removed from bourgeois society, he acts on his irrational whims and emotions, even if doing so would be unacceptable under normal circumstances. His desire to be back in his room is further evidence of the figurative “spell” the Berghof is casting on him: it’s almost as though the malaise of the sanatorium’s residents is more infectious than their physical illnesses. Of course, Hans’s exhaustion could also have a simpler explanation: he could literally be getting sick.
