It was an extraordinary game the two of them were playing; each perfectly aware that they lied and double-lied, each knowing that Hans Castorp teased the schoolmistress only in order to be able to talk about Frau Chauchat. He took a morbid and extravagant pleasure in thus trifling with Fräulein Engelhart, and she on her side reciprocated; first out of a natural instinct to be the go-between in a love-affair, secondly because to oblige Hans Castorp she had actually contrived to fall victim to Frau Chauchat’s charms; and finally because she felt a pathetic joy in having him tease her and make her blush. He well knew, and she well knew, all this about each other and themselves; each knew that the other knew and that the whole situation was equivocal and almost questionable. Equivocal and questionable situations were, in general, repugnant to Hans Castorp’s taste, and the present one was no exception. He felt disgusted, yet for all that he went on fishing in these troubled waters, quieting his conscience with the assurance that he was only up here on a visit and would soon be leaving.
