That morning, Karenin performs two tasks. He receives a delegation from the provincial racial minorities currently visiting Moscow, and writes the promised letter to his lawyer, enclosing three letters from Vronsky to Anna.
Having settled on his course of action regarding his family, Karenin feels more comfortable in carrying out the lawyer's plan.
Oblonsky arrives and insists on seeing Karenin.
Karenin turns down the dinner invitation. Oblonsky looks at him kindly, and the two men have a chat about Anna. Oblonsky begs Karenin to talk the matter over with Dolly.
Finally Karenin relents and agrees to come to dinner.
The two then chat about Oblonsky's new department head.
Oblonsky dashes off after securing a promise from Karenin that he'll come to dinner.
