Erotic rivalry recurs down the family line
Sandra's betrayal of Medea is replayed a generation later when Nika and Sandra's fragile granddaughter Masha become entangled with the same man, Butonov, and Masha kills herself. The novel shows inherited temperaments and unspoken family wounds recurring as repeated situations rather than repeated knowledge. Because the original secret was buried, the family cannot recognize the pattern while it repeats.
