This chapter is structured around two acts of reading: Anna reading the Oblonsky marriage, and the assembled characters reading Vronsky's inexplicable visit. Tolstoy uses free indirect discourse with particular precision in the first half, rendering Anna's successive inferences — 'God knows whether they are fully reconciled,' 'Yes, they must be reconciled,' 'Full, full reconciliation, full' — as a kind of interior counting-up that culminates in her kissing Dolly. The technique allows the reader to inhabit Anna's consciousness while simultaneously noticing that her conclusions are drawn from tone and posture rather than fact, establishing her as an acute but not infallible interpreter of social signs.
The motif of the child enters quietly but with structural weight. Anna's longing for Seryozha — surfacing at the hour she customarily puts him to bed — is the ostensible reason she leaves the room, and the album she fetches is a surrogate for his physical presence. Tolstoy places this maternal ache precisely at the moment that leads to her encounter with Vronsky on the staircase, implying a latent conflict between her role as mother and the pull of romantic attraction that will organise the rest of the novel.
The staircase encounter is rendered with extraordinary economy. Vronsky is glimpsed in a single paragraph: still, coated, pulling something from his pocket — a posture of arrested motion — before his eyes meet Anna's and register 'embarrassment and dismay.' Anna's response is equally compressed: 'a strange feeling of pleasure and at the same time of dread.' The oxymoron of pleasure-and-dread is the emotional signature of forbidden desire, and Tolstoy refuses to expand it, leaving it as a flash of sensation that Anna herself does not analyse.
Kitty's interior monologue after Vronsky's departure introduces dramatic irony: she believes she alone understands the visit, constructing a flattering narrative in which Vronsky avoided coming up out of consideration for the lateness of the hour and Anna's presence. The reader, however, has already seen that Anna is the reason for his hesitation in a sense Kitty does not suspect. This gap between Kitty's self-consoling interpretation and the truth Tolstoy has already planted foreshadows her eventual disillusionment.
The chapter closes on a collective, unarticulated unease — 'it seemed strange to all of them' — that functions as a form of narrative prolepsis. Tolstoy insists that the incident was objectively trivial while simultaneously insisting that everyone felt it was not, locating the disturbance in the realm of instinct rather than reason. This technique of socially shared but unspoken premonition is characteristic of Tolstoy's realism: the moral atmosphere of a scene is registered by the community of characters before any individual can name it.
