The subjectivity of the tetrads is an interesting point. The high-rise’s reversal into a slum absolutely highlights that; similarly, the tetrad on the brothel suggests a reversal into ‘hallucination for lonely hearts’, suggesting that loneliness is an integral factor of brothers. It seems there would be many reasons beyond loneliness for this to occur and that highlights only one emotion that it could reverse into.

I saw these tetrads, in a way, as almost journal-like. If two people wrote one on the same concept, surely they would come up with different parts of the tetrads. In fact, the mere existence of the alternate versions highlights that, right?
